Tulip (detailed introduction) leaf blight is a relatively common disease of tulips. This disease is more severe during the rainy season, and its pathogen is Botrytis tulipae Lind. The editor has compiled knowledge about tulip leaf blight for you. If your tulips have also been infected with leaf blight, you can study it together.
Tulip (detailed introduction)
Symptoms:Infected leaf buds develop poorly and become deformed and curled. Leaves that grow from damaged young buds become curled. If the environment is humid, a large amount of gray mold-like conidia will be produced on the diseased tissue, affecting nearby healthy plants and causing leaf infection, so bulb growth is greatly affected. After flowers are damaged, white or light yellow-brown lesions begin to appear, then they quickly wither and drop, or turn brown and dry up. Ring-like bands appear on the flower stalk, on which conidial layers sometimes develop. Every stage of this disease is highly likely to infect flowers. Sclerotia form on the outer shell of diseased bulbs, or round or oval sunken spots appear on the outer scales, with a grayish-yellow center and brown edges, containing one to several sclerotia inside.
Causes:The pathogen can produce conidia at 5 degrees and humidity of 90%-100%. The disease is severe when temperatures are low in spring and there is much rain and humidity.
Prevention and control methods:
First, remove diseased bulbs before planting and practice crop rotation; then, once buds or flower buds showing symptoms of this disease are found, remove them immediately to control disease development; next, before planting, soak the bulbs in 2% formalin solution for 30 minutes, dry them, and then plant to reduce residual pathogens; finally, during the growing period, spray 50% iprodione 1000x solution or 50% procymidone 2000x solution or 50% thiophanate-methyl 1000x solution.
Prevention and control of tulip leaf blight
Symptoms: Infected leaf buds develop poorly and become deformed and curled. Leaves that grow from damaged young buds become curled. If the environment is humid, a large amount of gray mold-like conidia will be produced on the diseased tissue, affecting nearby healthy plants and causing leaf infection, so bulb growth is greatly affected.
After flowers are damaged, white or light yellow-brown lesions begin to appear, then rapidly expand and cause withering and dropping, or turn brown and dry up. Ring-like bands also appear on the flower stalk, on which conidial layers sometimes develop. Every stage of this disease is highly likely to infect flowers. Sclerotia form on the outer shell of diseased bulbs, or round or oval sunken spots appear on the outer scales, with a grayish-yellow center and brown edges, containing one to several sclerotia inside. Pathogen: Botrytis tulipae Lind. belongs to Deuteromycotina and is commonly found in tulip cultivation areas, becoming more severe during the rainy season. Its conidiophores bear colorless or gray conidia, and the sclerotia are black, 1-2 mm in diameter, with a flat surface, round or oval.
Transmission route: Mycelium and sclerotia remain in decayed bulbs and soil to overwinter. After diseased bulbs are planted, a large number of conidia are produced on the damaged dead young buds, which are the source of infection for aboveground diseases.
Disease conditions: The pathogen can produce conidia at 5°C and humidity of 90%-100%. The disease is severe when temperatures are low in spring and there is much rain and humidity.
Prevention and control methods:
1. Remove diseased bulbs before planting and practice crop rotation.
2. Once buds or flower buds showing symptoms of this disease are found, remove them immediately to control disease development.
3. Before planting, soak the bulbs in 2% formalin solution for 30 minutes, dry them, and then plant to reduce residual pathogens.
4. During the growing period, spray 50% iprodione 1000x solution or 50% procymidone 2000x solution or 50% thiophanate-methyl 1000x solution.

Tulip cultivation methods and precautions, introduction to tulips
Tulip is a herbaceous plant of the genus Tulipa in the Liliaceae family, and is the national flower of Turkey, Kazakhstan, and the Netherlands. English names: Flower of Common Tulip, Flower of Late Tulip. Traditional Chinese medicine names: Tulip in "Supplement to the Materia Medica"; Tulip in "Taiping Imperial Reader"; red and blue flower, purple narrative fragrance in "Compendium of Materia Medica".
Tulip has 3-5 leaves, linear-lanceolate to ovate-lanceolate, flowers solitary and terminal, large and showy, tepals red or mixed with white and yellow, sometimes white or yellow, 5-7 cm long, 2-4 cm wide, 6 stamens of equal length, filaments hairless, no style, stigma enlarged and cockscomb-shaped.
In plant taxonomy, tulip is a type of bulbous herbaceous plant belonging to the genus Tulipa (scientific name: Tulipa) in the Liliaceae family. It is also called foreign lotus, dry lotus, grass musk, tulip fragrance ("Taiping Imperial Reader"), red and blue flower, purple narrative fragrance ("Compendium of Materia Medica"). Its place of origin ranges from southern Europe and western Asia all the way to Northeast China in East Asia. The well-known major exporting country the Netherlands first introduced tulips at the end of the 16th century. Because growing regions are at different latitudes, flowering periods vary, generally from late March to early May. Although there are about more than 2,000 tulip varieties worldwide, large-scale producers grow only about 150 kinds. It is the national flower of the Netherlands.
Tulips originated in the ancient Western Regions of China and the ** area of Tibet. As early as more than 1,300 years ago, the great poet Li Bai of China's Tang Dynasty left the line "Lanling fine wine with tulips, jade bowls filled with amber light" as clear evidence.
Later it spread through the Silk Road to Central Asia, and then from Central Asia into Europe and all parts of the world. At present it is cultivated all over the world. It is the national flower of the Netherlands, New Zealand, Iran, Turkey, Turkmenistan and other countries, and is called the queen of flowers of the world, becoming a symbol representing fashion and internationalization.
The origin of tulips is along the north and south coasts of the Mediterranean, Central Asia, Iran, Turkey, and east to Northeast China and other places. The exact origin is difficult to verify, but it is now mostly believed to have originated in Ceylon and the southwestern direction of the Mediterranean. Today tulips are commonly planted in every corner of the world, with cultivation being most prevalent in the Netherlands, becoming commercial production. As early as the 17th century, in the imperial gardens of the Ottoman Empire, they were specially planted for the royal and noble families to view.
The earliest tulips planted in Europe were introduced from Turkey. China began introducing them in the 19th century. Because growing regions are at different latitudes, flowering periods vary, generally from late March to early May. Although there are about more than 2,000 tulip varieties worldwide, only about 150 are produced in large quantities.
In flower beds such as the White House in the United States and the Louvre Museum in France, countless tourists come every year to browse and admire its beauty. Not only that, in artistic flower arrangement, it is also an extremely precious floral material. Its flower stem can reach as long as forty or fifty cm. Whether in a tall vase, shallow bowl, or round jar, it looks especially elegant and refined when arranged, fresh and meaningful, making people never tire of looking at it.
Tulip flowering period is April-May.
Morphological characteristics of tulips
Tulip is a perennial herb. The bulb is flattened conical, with a brown skin covering. The bulb is oval, about 2 cm in diameter. The outer layer is papery, and there are a few appressed hairs at the top and base on the inner side.
Tulip stems and leaves are smooth and covered with white powder. Leaves 3-5, elliptic-lanceolate or ovate-lanceolate, 10-21 cm long, 1-6 cm wide; basal leaves 2-3, relatively wider and larger, cauline leaves 1-2.
Tulip flowers are solitary at the top of the stem. Large, upright, forest-like, magenta, often dark purple at the base. Scape 35-55 cm long; flower solitary, upright, 5-7.5 cm long; petals 6, obovate, bright yellow or purplish red, with yellow stripes and spots: stamens 6, free, anthers 0.7-1.3 cm long, basifixed, filament base broad; pistil 1.7-2.5 cm long, style split to the base into 3, recurved. Flower shapes include cup-shaped, bowl-shaped, ovate, spherical, bell-shaped, funnel-shaped, lily-flowered, etc., with single and double forms. Flower colors include white, pink, magenta, purple, brown, yellow, orange, etc., in varying shades, single-colored or multi-colored.

The tulip flowering period is generally March-May, with early, middle, and late types. The capsule has 3 chambers, dehiscing along the back, with many seeds. The capsule dehisces along the back, and the seeds are flat.
Ecological habits of tulips
Tulips originated in the high mountain regions of Iran and Turkey. Due to the Mediterranean climate, tulips have formed the characteristic of adapting to wet and cold winters and dry and hot summers, with summer dormancy, rooting and sprouting new buds in autumn and winter but not emerging from the soil, and requiring low winter temperatures before beginning extended growth to form stems and leaves around early February of the following year (when the temperature is above 5°C), and flowering in March-April.
The suitable temperature for tulip growth and flowering is 15-20°C. Flower bud differentiation occurs during the storage period when the stems and leaves turn yellow, the bulbs are dug out of the pots, and placed in a cool outdoor place to spend the summer. The suitable temperature for differentiation is 20-25°C, and the maximum must not exceed 28°C.
Tulip is a long-day flower and likes a climate with sufficient sunlight, warm and humid winters, and cool and dry summers. It is very cold-resistant. In severe cold regions, if there is thick snow cover, the bulbs can overwinter in the open field, but it fears intense summer heat. If summer comes early and midsummer is very hot, it is difficult for the bulbs to survive the summer after dormancy.
Tulips require loose, fertile, well-drained slightly acidic sandy loam, and avoid alkaline soil and continuous cropping.
Conventional cultivation techniques for tulips
Field planting requires well-drained sandy soil, pH 6.6-7. Deep plow and prepare the land, use decomposed cow manure and leaf mold as base fertilizer, and apply a small amount of phosphorus and potassium fertilizer. Plant in beds, with planting depth of 10-12 cm. Generally, topdress after emergence, during flower bud formation, and after flowering.
In winter the bulbs take root. Before flowering in spring, topdress twice. They flower from late March to early April, and in early June the aboveground leaves turn yellow and enter dormancy. During growth, generally there is no need to water; keeping the soil moist is sufficient. In dry weather, water appropriately. The key points of cultivation and management are basically the same as those for hyacinths; only that tulip varieties are prone to hybridization, causing variety mixing, so isolated planting should be noted. Tulip bulbs contain a lot of starch and are easily eaten by mice during storage, so attention should be paid to storage.
Tulip belongs to bulbous plants. It needs to go through a certain low-temperature stage and can only flower normally after the flower stem has fully grown.
Conventional cultivation is a general cultivation method, one in which tulip bulbs have not undergone cold treatment.
Preparation before cultivation. Before planting tulips, a complete production plan needs to be made. The plan includes choosing and organizing the planting site, how to obtain tulip bulbs, preparation of production tools, and for potted cultivation, preparation of potting soil and containers.
Cultivation key points
Tulip bulbs should be planted in deep, fertile sandy soil. Their root growth hates waterlogging most, so the selected terrain must have smooth drainage. For planting beds, the bed width is generally [missing], the ditch depth is 30 cm, and on flat terrain the ditch should be deeper. If the soil in the first year of planting is relatively clayey, two cubic meters of peat and 5 kg of compound fertilizer per 100 square meters can be used as base fertilizer for soil improvement. Tulips should not be continuously cropped. Land where tulips have been planted in the previous one or two years is best not used for planting again. One month before planting tulips, the land should be deeply plowed and exposed to the sun to eliminate pathogen spores and remove weeds. Then choose clear weather, use 40% formalin 100x solution to irrigate (to a depth of more than 10 cm) for soil disinfection, then cover with plastic film for about one week. After removing the film, make the soil fine and prepare for planting.
Planting. Plant in sunny, well-drained sandy loam. Generally, planting can be considered when the soil temperature is stably below 12°C. After deep plowing, apply decomposed cow manure and other phosphorus and potassium fertilizers (apply 7-10 g phosphorus pentoxide and 13-15 g potassium oxide per square meter). The planting depth is about 2 times the height of the bulb, and the plant and row spacing is 2-3 times the transverse diameter of the bulb. After covering with soil, do not water again, but cover with straw to increase soil moisture and prevent soil compaction. Before the young buds just emerge and unfold leaves, apply 1 thin nitrogen fertilizer; after budding, increase the fertilizer concentration (10% fertilizer, 90% water). During the growth period, generally do not water; just keep the soil moist. If the weather is dry, water thoroughly 1-2 times (wetting depth about 15 cm). For those used as cut flowers, cut when the flower buds have completely changed color. The ornamental period in a vase is about 10 days.
Before planting, the bulbs should be disinfected. They can be soaked in potassium permanganate solution or formalin solution for 30 minutes, then dried and planted. The density for productive planting can be controlled at 12×12 cm or 13×12 cm, with slight differences depending on the variety. Generally, varieties with strong upright leaves and short plants can be planted more densely.
Potted treatment
If grown for exhibition, the spacing can be 20-25 cm, and the planting depth is 4-5 cm from the top of the bulb to the soil surface. After planting, water thoroughly once to prevent drying and dehydration. Tulips are mostly grown in pots for ornamental purposes, and also used as ground cover plants and medicinally.
Cultivation method for bulbs treated at 5°C for 12 weeks: Tulip bulbs treated at 5°C for 12 weeks have completed scale nutrient conversion and can be directly used for greenhouse pot cultivation. From November to December, use 5-inch to 6-inch pots, place them on the ground, 3-4 bulbs per pot. The soil covering the bulbs should be shallow, preferably so that the bulb tips can be exposed at the pot soil surface. When planting, the soil moisture must be high, because roots grow quickly and do not need much water. The optimum growth temperature is 15°C, maintain 5°C-18°C, and it must not exceed 18°C. They can flower in 5-6 weeks; in addition, ventilation in the greenhouse should be good, and water droplets must not appear on the greenhouse film. They can bloom in January-February when flower prices are high.
Cultivation method for bulbs treated at 9°C for 16 weeks: Bulbs treated at 9°C are suitable for bed planting in greenhouses. Cover the bulbs with 2-5 cm of soil. The soil should be moist and loose. The planting density is 230 bulbs/sq m-250 bulbs/sq m (circumference s=11 cm-12 cm). The management method is the same as for 5°C tulips; but flowering is 1 month later than for 5°C-treated bulbs. Plant in November-December, flower in February-March, and they can be sold as fresh cut flowers or potted flowers.
Cultivation method for natural bulbs without low-temperature treatment: Because natural bulbs have not undergone low-temperature treatment, nutrients have not been transferred to the flower primordium, and the flower bud nutrition is insufficient, so natural bulbs must be planted in the open field and undergo natural cold treatment. When planting, the planting site should be deeply plowed 30 cm to ensure loose soil. The planting density of bulbs varies according to bulb diameter. Generally, the planting depth should be 10-11 cm; large bulbs can be planted 15 cm deep. Planting time should be from October to the end of November. Do not water after planting. If planted after November 15, a thin layer of straw bag can be covered on top. Until May 1 of the following year, do not water; under normal circumstances, no fertilization is needed. If selling cut flowers, cut from the base of the flower stem; if propagating bulbs, cut from the neck of the flower. Dig bulbs in June-July. There are 3-4 small bulbs around a large bulb. Separate the large and small bulbs, and do not break the bulb skin. Store bulbs of different sizes at different temperatures: small bulbs at 12°C-18°C, large bulbs at 18°C-20°C, and later store according to different needs with 5°C, 9°C, and natural bulb treatments.
The key points of cultivation and management are basically the same as those for hyacinths; only that tulip varieties are prone to hybridization, causing variety mixing, so isolated planting should be noted. Tulip bulbs contain a lot of starch and are easily eaten by mice during storage, so attention should be paid to storage.
Field management
Temperature regulation
The suitable temperature during the tulip growth period is 5-20°C, with the optimum temperature being 15-18°C. The plant growth temperature should be maintained at 0-25°C. The root growth temperature of tulips should preferably be above 5°C and below 14°C, especially around 10°C, which is best. The suitable temperature for flower bud differentiation is 17-23°C. When it exceeds 35°C, flower bud differentiation will be inhibited. In addition, tulips are extremely cold-resistant and can withstand low temperatures of -35°C in winter. When the temperature remains above 8°C, they begin to grow.
Water management
During cultivation, never overwater. However, within one week after planting, the water requirement is relatively high and should be watered sufficiently. After germination, the water requirement decreases, especially at flowering time when water must not be excessive. Watering should follow "small amounts, many times." If too dry, growth will be significantly delayed. During the tulip growth period, the air humidity should preferably be maintained at around 80%.
Light conditions
When the bulbs germinate, the elongation of their flower buds is inhibited by sunlight. Therefore, they must be planted deeply and moderately shaded to prevent direct sunlight from adversely affecting bulb growth.
Soil and fertilization
Sandy loam is best, and the soil pH should preferably be neutral to slightly alkaline. Tulips prefer fertilizer, so sufficient base fertilizer should be applied before planting. Generally, dried chicken manure or decomposed compost is used as base fertilizer and watered thoroughly. Two to three days before planting, carefully plow and harrow to ensure loose soil. After the bulbs produce two leaves, apply 1-2 liquid fertilizer topdressings. During the peak growth season, apply a balanced nitrogen, phosphorus, and potassium compound fertilizer 3-4 times per month. Stop fertilizing during the flowering period. After flowering, apply 1-2 liquid fertilizers of potassium dihydrogen phosphate or compound fertilizer.
Bulb storage
The storage conditions of bulbs directly affect flower bud differentiation within the bulbs and the flowering time of the plants. After harvest, bulbs should be placed in a ventilated, dry, and cool place as much as possible. If conditions permit, in the high-temperature season of July-August, place the bulbs in a 15-17°C cold storage, then the bulbs will develop smoothly and flower bud differentiation and development will be promoted. If the bulbs are placed at a high temperature above 35°C, flower bud abortion and deformed development will occur.
Key maintenance points for tulips
Tulips are highly cold-resistant and can withstand low temperatures of -35°C in winter. They can also grow normally at 5-8°C, making them suitable for winter forcing cultivation.
Tulip forcing cultivation means breaking the dormancy of the flower primordium and leaf primordium through temperature variation treatment of the bulbs, eliminating factors that inhibit flower bud germination, and promoting flower bud differentiation. Then, through artificial temperature increases, supplementary lighting, and other measures, tulips are made to flower outside their natural flowering period. Commonly seen on the market are 5°C bulbs and 9°C bulbs. We generally choose 5°C bulbs for forcing cultivation to bloom at Spring Festival.
Substrate preparation
First, prepare a high-quality substrate that is both water-retaining and breathable. Salinity must not be too high, and it must not be too acidic. The pH value should be no less than 6, and it should be free of pests, diseases, and harmful substances. The bulbs should be planted very firmly in a sufficiently deep cultivation bed (at least 5 cm deep). In recent years, we have used a 1:1:1 mixture of peat, decomposed soil, and sand as the cultivation substrate, with good results. About half a month before planting, apply decomposed farmyard manure into the bed soil as base fertilizer, and add an appropriate amount of carbofuran and carbendazim (or irrigate with 1% formalin and cover for disinfection). Water thoroughly, and carefully plow and harrow before planting to ensure loose soil.
Planting
Because the ground temperature in the greenhouse is high, tulips will undergo late vernalization, and the low-temperature treatment effect of forcing cultivation will be reduced. Therefore, early planting is not as good as late planting. Generally, plant about two months before Spring Festival, around early to mid-November. Before planting, remove the brown bulb skin and soak in 50% carbendazim 500x solution for about two hours. The plant and row spacing is 9×10 cm. When planting, the top of the bulb should be level with or slightly below the soil surface. Proper shallow planting can advance flowering. Sometimes when about 1/3 of the tulip bulb is exposed above the soil surface, flowering can be advanced by more than 5 days. After planting, water thoroughly to promote rooting.
Cultivation management temperature
Generally after one week, the bulbs begin to germinate. Before emergence and during the seedling stage, keep the indoor temperature at 12-15°C during the day. If the temperature is too high, ventilate promptly to cool it down. At night it should not be lower than 6°C, to promote early rooting, strong rooting, and cultivate strong seedlings. If the temperature is too high at this time, the plant stems will be weak and flower quality poor. After more than 20 days, when the plant has grown two leaves, increase the temperature promptly to promote the flower buds to separate from the bracts in time. Keep the indoor temperature at 18-25°C during the day and above 10°C at night. Generally after another 20-plus days, the flower crown begins to color. The first flower opens from late December to early January, and it takes 10-15 days to reach full bloom. At this time, place them in batches according to different flower requirement times. The higher the temperature, the earlier the flowering. Generally, after the flower crown is fully colored, the plants should be placed in a 10°C environment for sale.
Light
Sufficient light is essential for tulip growth. Insufficient light will cause poor plant growth, cause bud drop, weaken the plant, lighten leaf color, and shorten the flowering period. However, within more than half a month after potting, tulips should be properly shaded to help the bulbs grow new roots. In addition, when germinating, flower bud elongation is inhibited by light. After shading, flower bud elongation can be promoted, preventing excessive vegetative growth and legginess in the early stage. After emergence, light should be increased to promote stem elongation, form flower buds, and promote coloring. After the flower buds are fully colored in the later stage, direct sunlight should be prevented to prolong flowering time.
Fertilization
Because the substrate is rich in organic fertilizer, no additional topdressing is needed during the growth period. However, if nitrogen is insufficient and leaf color becomes lighter or the plant grows insufficiently robust, easily absorbed nitrogen fertilizers such as urea and ammonium nitrate can be applied, but the amount must not be large, otherwise it will cause legginess and may even affect the plant's absorption of iron, causing iron deficiency (when iron is deficient, new leaves and flower buds all turn yellow, but old leaves remain normal). Applying liquid fertilizer during the growth period has a notable effect. Generally, from budding to flowering, spray potassium dihydrogen phosphate solution at a concentration of 2‰-3‰ once every 10 days to promote large flowers, bright colors, and sturdy, upright flower stems.
Water
After planting, water thoroughly so that the soil and bulbs can fully bind closely, which is beneficial for rooting. After budding, water should be properly controlled. When the leaves gradually extend, water can be sprayed on the leaf surface to increase air humidity. During the scape-extending stage and budding stage, sufficient water supply must be ensured to promote full flower development. After flowering, properly control water.
Other
Potted tulips are directly managed after potting. Because bulb quality varies, growth and flowering are uneven, affecting their commercial quality. Therefore, it is best to first plant them in the greenhouse ground, then manage them in pots after the flower crown colors. This does not affect flowering quality and gives better results.
Among flower colors, red flowers bloom earliest and yellow latest, generally about 10 days apart. During cultivation, planting times should be staggered appropriately to ensure simultaneous flowering.
Potted techniques for tulips, potted maintenance
Tulips can be planted in the ground or in pots. For cultivation time, both planting methods can be carried out in late October.
For field planting, the plant and row spacing is 14-16 cm. Apply sufficient base fertilizer. The soil covering depth is about 4 cm, and the ditch depth is 15-20 cm. Water after planting. Before and after germination and flowering, apply 2-4 light fertilizer applications.
For potting, choose plump and large bulbs. A 30 cm flowerpot can hold 3-5 bulbs. The top of the bulb should be level with the soil surface. After planting in autumn, bury the pot in soil, then dig it out in spring, place it in a sunny, well-ventilated place, and water and fertilize normally, and it will flower on time.
Cultivation experience
It requires growth in well-drained sandy loam rich in humus. A small amount of decomposed manure and bone meal can be mixed in as base fertilizer.
It likes cool conditions, but has strong adaptability. It can face wet and cold winters and also adapt to dry and hot summers, but summering should not exceed 27°C. If the temperature is too high, leaves will become leggy, the leaf-to-flower ratio will be unbalanced, and flowering will be poor; the suitable growth temperature is 15-20°C. It can grow normally above 8°C, but can also withstand low temperatures of -14°C.
During the growth period, generally keeping it moist is sufficient. Apart from appropriate watering during drought, generally large amounts of water are not needed; in winter it mainly grows roots and grows slowly, so it may be not watered or very little watered; spring is the peak growth period for flower buds and leaves, so it can be watered appropriately; after flowers fade, the main focus is bulb growth, so water should again be properly controlled.
Only with sufficient light can flowers bloom well and the ornamental period be extended. Insufficient light will result in incomplete opening or even closed flowers that do not open.
During important growth periods such as after emergence, during flower bud formation, and after flowering, topdressing should be carried out. Diluted liquids such as sesame paste residue, horse hoof water, and ferrous sulfate can all promote growth. Do not use urea for topdressing.
For those aimed at growing bulbs, once the flower buds color, they should be removed immediately to avoid consuming nutrients; for those aimed at cut flower production, they can be cut only after the flower buds have completely changed color.
If flowers show patterns, it is caused by viral infection and they should be dug out and burned immediately to avoid contagion and spread.
Forcing cultivation
To make them available for Spring Festival needs, choose early-flowering varieties and plant them in early October on the light-receiving side of a hotbed or greenhouse. Move them into a greenhouse in early December and sprinkle water once a day. They can bud in about 20 days. If earlier flowering is desired, the greenhouse temperature should be kept at 16-18°C, and all sides should be covered so they do not receive sunlight. After two weeks, place them in a sunny place and lower the temperature appropriately. They can flower after six weeks.
Hydroponic methods for tulips, hydroponic production methods
For hydroponics, a rooting nutrient solution must be used. After planting and adding water, place the planting tray in a rooting room at 5°C with a small amount of air circulation. Replenish water in a timely manner. When watering, tap water with a conductivity value of 1.5 ms/cm can be used, and rainwater can also be used. For varieties prone to leaf splitting, water with a conductivity value of 2 ms/cm should be used during the rooting stage.
Tulip is a perennial herbaceous plant of the Liliaceae family and is welcomed by people because of its large, brightly colored flowers. Because it sells well on the market, countries have devoted themselves to researching its cultivation techniques, and hydroponic cut flower production has gradually become popular among professional growers. China began introduction trials and cultivation in the 1990s.
Hydroponic experience
Selecting suitable and disease-free bulbs is the key to hydroponic production of tulip cut flowers.
After the bulbs are transported back, they must be stored in a well-adjusted cold storage at 5°C and humidity within 80%. Check in time and select out bulbs with severe penicillium disease.
According to the required flowering time, choose and determine the cultivation time and planting method. For hydroponic cut flower cultivation, the bulbs should be planted in disinfected and leak-proof needle trays, with the rooting temperature kept stable at 8°C and humidity between 60% and 70%.
After about two weeks of rooting, once the roots have reached a length of more than 3 cm, move the needle trays into the greenhouse. Keep the temperature at 15-20°C and the humidity at 60%-70%, and add nutrient solution to bring the Ec value of the water to 1.5 ms to 2.0 ms, so as to promote the rapid growth of the tulips.
In the early stage of growth, to prevent diseases caused by filamentous fungi, spray 2 to 3 times. Choose low-toxicity, high-efficiency fungicides such as chlorothalonil, thiophanate-methyl and thiram, at a concentration of 750-1000 times dilution.
Spray foliar fertilizer at the appropriate time according to growth conditions, to balance vegetative growth and reproductive growth.
During growth, due to root exudates and other environmental conditions, an oily film forms on the surface of the water in the needle tray, which deprives the roots of nutrient supply and causes the roots to turn brown. Therefore, change the water 2 to 3 times as needed.
When harvested cut flowers cannot be shipped out in time, they must be placed in a cool, ventilated place, avoiding strong light, high temperatures and low temperatures, which would affect the quality of the cut flowers.
Propagation methods of tulips
Tulip propagation and cultivation is generally based mainly on separating small bulblets, as follows: the annual mother bulb, after flowering, sprouts 1 to 3 new bulbs at the base of the bulb that can flower the following year, along with 2 to 6 small bulblets, while the mother bulb gradually dries up. The bulbs can be dug out, the soil removed and dried, and the baby bulbs separated from the bulb and stored in a ventilated place at 5 to 10°C; by autumn, the baby bulbs can be planted in soil rich in leaf mold with an appropriate amount of phosphorus and potassium fertilizer, with a plant and row spacing of 14 to 16 cm, a trench depth of 15 to 20 cm, and a covering soil depth of 4 cm; note, however, that any baby bulb that is round, however small, can flower, while baby bulbs that are flat generally will not flower; after planting the baby bulbs, water them thoroughly, and just keep them moist at ordinary times. The following spring, begin normal fertilizer and water management for the flower seedlings, and they will flower in 2 to 3 years. Seed propagation is generally used only for breeding and large-scale propagation, but it takes 4 to 5 years to flower.
Tulips are divided and planted as small bulbs in autumn, from September to October. The mother bulb is annual, that is, renewed every year, drying up after flowering, with a new bulb and several bulblets growing beside it; in autumn the new bulb and bulblets are separated and planted. Autumn sowing propagation is also possible. The number of bulblets produced within the scale leaves of the mother bulb varies with the variety and is also related to cultivation conditions. The swelling of the new bulb and bulblets is usually completed within one month after flowering.
Bulb division and seed propagation are commonly used.
Bulb division propagation
After a season of growth, the mother bulb planted that year can simultaneously produce 1-2 large bulbs and 3-5 small bulbs around it. They can be planted separately according to bulb size; large bulbs can flower in the same year after planting, and small baby bulbs can also flower after 1-2 years of cultivation.
Seed propagation
Tulip seed propagation is mostly used for breeding new varieties. The seeds are harvested before the capsules mature and split, stored in sand until October, then sown in pots indoors. Keep them moist; they will not germinate until the following spring. They flower in about 3-4 years.
Seed propagation is generally used only for breeding and large-scale propagation. But it takes 4-5 years to flower, so bulb division is generally the main method, as follows: the annual mother bulb, after flowering, sprouts 1-3 new bulbs at the base of the bulb that can flower the following year, along with 2-6 small bulblets, while the mother bulb gradually dries up. The bulbs can be dug out, the soil removed and dried, and the baby bulbs separated from the bulb and stored in a ventilated place at 5-10°C; by September in autumn, the baby bulbs can be planted in soil rich in leaf mold with an appropriate amount of phosphorus and potassium fertilizer, with a plant and row spacing of 14-16 cm, a trench depth of 15-20 cm, and a covering soil depth of 4 cm; note, however, that any baby bulb that is round, however small, can flower, while baby bulbs that are flat generally will not flower; after planting the baby bulbs, water them thoroughly, and just keep them moist at ordinary times. The following spring, begin normal fertilizer and water management for the flower seedlings, and they will flower in 2-3 years.
Flowering regulation of tulips
Tulips are cold-tolerant but not heat-tolerant; they can generally withstand low temperatures of -30°C, and enter dormancy in hot seasons. They usually prefer moist, cool climates and a sheltered, sunny environment, and grow better in neutral or slightly acidic soil. A mature tulip bulb contains three generations of bulbs, or three generations of planting stock. The large bulb itself is the first-generation bulb, with fully differentiated flower organs, and flowers in the same year after planting. The second- and third-generation bulbs are bulblets, which can be cultivated into large bulbs.
Tulip bulbs must undergo a certain amount of low temperature before they can flower. In their place of origin, winters generally provide sufficient low-temperature time, so tulip bulbs can obtain enough low-temperature treatment time and flower naturally in spring. Generally speaking, tulip bulbs used in production are given 5°C treatment and 9°C treatment, and after treatment the planting methods are mainly greenhouse cultivation and forcing cultivation in boxes.
In South China and other southern regions, tulip cultivation is limited by temperature, so planting is done during the three months from December to February of the following year. In December, temperatures in South China may still be very high; at this time, tulips can be grown in cultivation boxes and placed in a cold store at about 5°C for 2-3 weeks. Once the tulip bulbs have grown roots and the shoots are about 1-2 cm long, move them out of the cold store and place them in a planting shed to grow.
To ensure that tulips flower on time, try to maintain daytime temperatures of 17-20°C and nighttime temperatures of 10-12°C during the growth period. When temperatures are high, the temperature can be lowered by shading and ventilation; when temperatures are too low, growth can be promoted by heating and increasing light. Using water control to inhibit growth will cause a "dry flower" phenomenon. If high temperatures persist, box-grown plants can have their boxes moved into a cold store; note that the cold store temperature should be around 8-10°C, and it is best to move them in when the flower stems are elongating, otherwise it easily causes poor bud development. Tulip flowering can also be regulated by plant growth hormones. For example, soaking tulip bulbs in gibberellin causes them to flower in the greenhouse and can increase flower diameter.
Harvest and freshness preservation
Harvesting and freshness preservation of cut flowers: once the buds are fully colored, they can be harvested and marketed. Those managed at a slightly lower temperature can color gradually; but those forced to flower early at high temperatures color poorly. At the same time, those that color late are easily damaged during transport and market transactions. Therefore, when flowering is near, avoid excessively high temperatures, maintain good ventilation while providing adequate shading, and when cutting the flowers, since the bulbs are easily pulled up, use pliers to cut, keeping as much of the stem inside the bulb as possible. Cut flowers are sorted according to variety, plant height and flower size, tied in bunches of 10 and packed for transport. For vase freshness preservation, a mixture of 10×10-6 algaecide ammonium, 2.5% sugar and 10×10-6 calcium carbonate can be used, or a mixture of sugar, chlormequat and 8-hydroxyquinoline citrate.
Post-harvest technology
Main characteristics of cut flowers: the longer the low-temperature forcing cultivation at night, the longer the vase life of the cut flowers.
Harvest and cutting developmental stage: the optimal cutting time for tulips varies by variety. Generally, cut when the flower is 1/2 colored. Immediately after cutting, place in an environment at 2°C and at least 85% relative humidity.
Vase life: the shortest vase life is only 3-4 days, and the longest is about 5-7 days.
Preservative treatment method: preservative solutions cause the flower stems to elongate excessively and have little effect on extending vase life. Therefore, preservative solutions are generally not used.
Storage and transport technology: they can be stored dry (placed horizontally) or wet (placed vertically) at 2°C, with the flower heads tightly wrapped in plastic film, but they should not be stored long-term. Some varieties are harvested together with the bulb at the green bud stage and can be stored at 0°C for 2-3 weeks.
Retailer and consumer handling methods
(1) Re-cut the flower stems, insert the cut flowers into water 15-20 cm deep, wrap the flower heads in plastic film, and rehydrate at room temperature until the cut flowers are firm.
(2) Cut flowers stored at 2°C have the longest vase life.
(3) Arrangements should be placed in a cool, windless environment, not near a stove. Tulips are phototropic, so indoor light should be evenly distributed to avoid stem bending.
(4) Do not put tulips and daffodils in the same container, otherwise the life of the tulips will be shortened. Tulips may cause redness and swelling of the skin of the hands, so handle them with care.
Disease control of tulips
The main diseases of tulips are bulb rot caused by decay fungi, gray mold and color-breaking petal disease. The control methods are, first, to choose virus-free bulbs as far as possible, and disinfect the soil and bulbs, promptly burn diseased bulbs and diseased plants, etc., then spray with 5% benomyl wettable emulsion at 2500 times dilution every half month. The main insect pests of tulips are aphids and root mites; aphids are generally controlled by spraying 40% dimethoate emulsion at 1000 times dilution.
Pathogen
TuBV is called tulip breaking virus. The virus particles are filamentous, 700×12-13 nm or 750-175x15 nm in size, with bundle-shaped or coil-shaped inclusion bodies; the thermal death point is 65-70°C, the dilution end point is 0.00001, and the longevity in vitro at 18°C is 4-6 days. This virus has two strains, a virulent strain and a mild strain. The former causes faded mottling on leaves and flower stalks. This virus is closely related to lily latent virus LSV. In addition, CMV, TRV and TNV are also pathogens of this virus, and their plastids are all spherical. Tulip breaking virus can also harm lilies, Cape asparagus fern and yellow fritillary, etc.
Distribution area:
Disease characteristics: tulip breaking virus can be transmitted by sap, aphids and bulbs. The tulip bulb aphid mainly transmits the virus during bulb storage, but not during the growth period. In Shanghai and other places, most varieties of planting bulbs imported from the Netherlands can only be grown for 2-3 years, after which they gradually degenerate and become smaller, and may even fail to flower; this virus is the main cause of the degeneration.
Control methods:
(1) Choose disease-free bulbs as propagation material. For introduced tulip bulbs, virus elimination should be carried out centrally using a combination of shoot-tip culture and heat treatment, and virus-free breeding bases should be established to obtain virus-free seedlings before they enter the market.
(2) If tulip bulb aphids are found active during bulb storage, or other aphids are found in the field, promptly spray 40% dimethoate emulsifiable concentrate at 1000 times dilution to kill them and prevent virus transmission.
(3) Promptly pull out and remove diseased plants found in the field.
(4) Fields planted with tulips should preferably be far away from Lilium plants to prevent virus transmission.
(5) In areas with severe disease, it is still safer in production to choose relatively disease-resistant single-flowered tulip varieties.
Preventing bulb rot in tulips
In tulip cultivation, bulb rot often occurs. The main causes are: the dug-out bulbs were not dried and carry disease-carrying soil, and during storage the high temperature and high humidity are suitable for pathogens to reproduce and spread, causing the bulbs to rot; during cultivation, soil carrying pathogens (mostly Fusarium) and incompletely decomposed fertilizer are used, and the bulbs suffer pathogen damage, causing bulb rot; the potting soil is clayey, and with overwatering it causes waterlogging in the pot, causing the bulbs to rot from waterlogging; the bulbs are dug up too early, and the new bulbs are not plump enough, which also easily causes rot. The method to prevent bulb rot is to take corresponding measures according to the above causative factors.
Pest and disease control
The main pests and diseases of tulips include rot disease, sclerotinia disease, viral disease, thrips, foxglove aphid and root lice, etc.
After infection with sclerotinia disease, yellow or brown slightly raised round spots appear on the scales, and sclerotia form in the slightly sunken inner parts. When the pathogen infects the stem, it produces long oval lesions, and sclerotia form at the soil surface. Control methods: first, disinfect the soil before planting; second, immediately pull out diseased plants after onset and spray with zineb at 500 times dilution.
Viral disease is one of the main causes of tulip germplasm degeneration. There are many viruses harming tulips; in China the common ones are mosaic virus and breaking virus. Mosaic virus causes yellow stripes or fine speckled spots on affected leaves, and dark spots on petals; in severe cases the leaves rot, so aphids should be controlled promptly and weeds removed. Breaking virus causes pale yellow or grayish-white stripes or irregular spots on diseased leaves, sometimes forming a mosaic, and pale yellow or white stripes or irregular spots on petals, producing color-breaking flowers on red or purple varieties. Its control methods are the same as for general viral diseases, but the planting site should be far from lilies.
Root lice feed on bulbs in the soil, burrowing into the epidermis to suck sap, causing plants to grow weakly or to rot easily or to be induced to develop diseases. Soaking infested bulbs in thin limewater for 10 minutes, then taking them out and rinsing them clean, can kill the root lice.
1. Tulip southern blight
Symptoms: the whole plant wilts, white mycelial strands or rapeseed-like tea-brown small sclerotia wind around the stem base, and the affected part turns brown, decays and rots. Large amounts of white mycelial strands and tea-brown fungal bodies can be seen on the soil surface.
Pathogen: SclerotiumrolfsiiSacc., called the southern blight fungus, belongs to the Deuteromycotina fungi. The hyphae are white and silky, spreading in a fan or radial shape, later gathering into mycelial strands or tangling into sclerotia. The sclerotia resemble rapeseeds, initially white to yellowish-white, later turning tea-brown, round, with a smooth surface. In addition, it has been reported that Corticiumrolfsii(Secc.)Cyrzi. is also a pathogen of this disease.
Transmission routes: 1. The pathogen overwinters in the soil with diseased residues as sclerotia or mycelial strands, and when conditions are suitable the following year, the sclerotia or mycelial strands produce hyphae for primary infection. 2. The silky hyphae produced by the plant extend to contact neighboring plants, or sclerotia are spread by water flow for re-infection, causing the disease to spread and expand; the disease is severe in continuous cropping or clayey soil, low-lying terrain, or years or seasons with high temperature and high humidity.
Control methods: when diseased plants are found, promptly pull them out and burn them, and drench the diseased holes and nearby plants with 5% jinggangmycin aqueous solution at 1000-1600 times dilution, or 50% tianan aqueous solution at 500-600 times dilution, or 20% tolclofos-methyl emulsion at 1000 times dilution, or 90% fenaminosulf wettable powder at 500 times dilution, sprinkling and drenching 0.4-0.5 liters per plant (hole). In conjunction with plowing, apply 100-150 kg of lime powder per mu to make the soil slightly alkaline, which can inhibit the reproduction of the southern blight pathogen.
2. Tulip leaf spot
Symptoms: infected leaf buds develop poorly, appearing deformed and curled; after the young buds are damaged, the leaves that grow become curled. If the environment is humid, a large number of gray mold-like conidia are produced on the diseased tissue, affecting neighboring healthy plants and causing leaf infection, so bulb growth is greatly affected. After flowers are damaged, white or light yellowish-brown lesions initially appear, then they quickly wither and drop, or turn brown and dry up. Ring bands appear on the flower stalk, sometimes with a conidial layer on them. Every stage of the disease is highly prone to infecting flowers. Sclerotia form on the outer shell of diseased bulbs, or round to oval sunken spots appear on the outer scales, grayish-yellow in the center and brown at the edges, containing one to several sclerotia.
Pathogen: BotrytistulipaeLind. belongs to the Deuteromycotina, and is commonly found in tulip cultivation areas, being more severe in the rainy season. Transmission routes: hyphae and sclerotia remain in rotting bulbs and soil to overwinter. After diseased bulbs are planted, a large number of conidia are produced on the damaged and dead young buds, which are the source of infection for aboveground diseases.
Onset conditions: the pathogen can produce conidia at 5°C and humidity of 90%-100%. The disease is severe in spring when temperatures are low and rainy days are humid.
Control methods:
(1) Remove diseased bulbs before planting and practice crop rotation.
(2) Once buds or flower buds showing symptoms of this disease are found, remove them immediately to control the development of the disease.
(3) Before planting, soak the bulbs in 2% formalin solution for 30 minutes, then dry them and plant, to reduce residual pathogens.
(4) During the growth period, spray 50% iprodione at 1000 times dilution, or 50% procymidone at 2000 times dilution, or 50% duomeixun at 1000 times dilution.
3. Tulip black rot
Symptoms: the bulb becomes diseased. On the stem plate and stem surface, sometimes on the 2nd and 3rd scales, irregular lesions initially yellowish-brown and later black appear, with a rough surface.
Pathogen: Pseudomonasandropogonis(Smith)Stapp, a Pseudomonas bacterium. The bacterial cells are rod-shaped, 1.9*0.8 micrometers in size, with 1-3 polar flagella. The optimum temperature for onset is 20-25°C, and the minimum is 5°C.
Transmission routes: infected bulbs and diseased residues in the soil are the sources of infection.
Control methods: try soaking the bulbs in agricultural streptomycin sulfate solution for disinfection.
4. Tulip mosaic disease (CMV)
Symptoms: mosaic-like markings and chlorotic streaks appear on leaves, sometimes necrotic spots occur, and dark spots appear on petals. Growth and development are inhibited. When symptoms are severe, the bulbs do not grow large, and the damage is great.
Pathogen: cucumber mosaic virus (CMV).
Transmission routes: this virus occurs on many crops and weeds and is transmitted non-persistently by aphids.
Control methods:
(1) Use healthy bulbs.
(2) Control aphids promptly.
5. Tulip wilt disease
Symptoms: dark brown and gray sunken spots appear on the outer scales of the bulb, later expanding into medium-dark brown lesions. If diseased bulbs are placed in a warm, humid place, white or pink hyphae and conidia grow on them, causing the diseased tissue to shrivel and harden. After the bulb base is damaged, the rapidly developing lesions can spread across all scales; the ethylene produced by diseased scales causes healthy bulbs to exude gum, affecting growth. The leaves on the bulb show premature aging, and some leaves appear upright and gradually turn a characteristic purple. The flowers produced are thin and small, deformed, and may even wither. In a greenhouse, infected plants will yellow and die prematurely.
Pathogen: FusariumoxysporumSch1.f.sp.tulipaeApt.; microconidia are 5-12*2.2-3.5 micrometers, and macroconidia have 3-5 septa, measuring 30-60*3.5 micrometers.
Control methods:
(1) Delay planting appropriately and dig up bulbs early, avoiding the high-temperature period as much as possible, so as to prevent rampant damage by the pathogen.
(2) Healthy bulbs should be stored separately in a ventilated, cool place (below 15°C).
(3) Do not plant too densely, and promptly remove diseased plants found during the growth period.
(4) Within 48 hours of digging up the bulbs, soak them in a 50% benomyl wettable powder aqueous solution for 15-30 minutes, then dry them and store.
(5) Plant disease-free bulbs and implement a three-year crop rotation system.
6. Tulip color-breaking petal disease
Symptoms: the main symptoms appear on the flowers. On the same flower, the petal color shows varying degrees of change; some colors deepen, some remain normal, and some fade. Some become variegated mottling, and some become striped. Affected leaves show lighter-colored spots or stripes, and in many varieties the anthocyanin on the outer side of the first leaf shows irregular stripes.
Pathogen: tulip breaking virus (TulipBreakingVirus, TuBV); the thermal death point of the virus is 65°C-70°C.
Transmission routes: it overwinters and oversummers as sclerotia in bulbs and soil. During the growth period it is transmitted by aphids. The knives and scissors used when cutting flowers can also transmit it.
Control methods:
(1) Choose virus-free plants as propagation material.
(2) Promptly remove diseased plants.
(3) Spray 40% dimethoate emulsifiable concentrate at 1000 times dilution, or 40% omethoate emulsifiable concentrate at 1000 times dilution, or 2.5% rotenone at 800 times dilution to control aphids.
(4) When cutting flowers, the knives and scissors should be heat-sterilized or washed clean with detergent before use.
Causes of blind shoots and blind flowers
Tulips belong to the Liliaceae family, Tulipa genus, perennial bulbous herbaceous plants. They have an upright plant shape and large, showy flowers, with high ornamental value. However, if not cared for properly, tulips are prone to blind shoots and blind flowers.
Blind flower symptoms are shown as normal development of branches and leaves; in weak-growing plants, the flower bud loses water and appears white, pointed like a leaf tip, and the flower stem shrivels; in strong-growing plants, the flower stem is short, the petals remain green or white, and they curl together with the stamens and pistils, unable to open fully. A blind shoot means the aboveground part of the plant bears only one large leaf, with no leafy branches, let alone flower branches.
The causes of their formation are as follows
Related to variety, biological characteristics and cold treatment time
Because tulips were tempered by harsh natural conditions in their place of origin over a long period, they not only developed the varietal characteristic of being cold-tolerant but not heat-tolerant, but also acquired the biological characteristic of requiring a certain period of low-temperature treatment before the stems and leaves grow fully and they can flower. In northern China, autumn and winter planting in the open field can satisfy the low-temperature requirement, and they flower in April-May of the following year. Using this characteristic to give tulip bulbs 9-5°C low-temperature treatment allows forcing cultivation and year-round flower supply. The blind flower phenomenon in production is mainly caused by bulbs not having undergone low-temperature vernalization or having too short a cold treatment time, thus failing to meet the flowering requirement.
Related to bulb size and intermediate temperature
In production, bulbs above 12 cm are mostly used as planting stock; such bulbs have fully developed flower buds and mostly show no blind flowers; bulbs below 10-11 cm are mostly used for open-field planting, and after one year, once the flower buds are fully developed, they can also flower normally; if used for forcing cultivation, the blind flower rate is relatively high. This is mainly because most of the flower buds of such sized planting stock are not yet fully developed, and before cold treatment they must be given 1-3 weeks longer intermediate temperature treatment at 17-20°C than bulbs with a diameter of 12 cm. If the planting stock is uneven in size, the intermediate temperature treatment is improper, and forcing cultivation is then carried out, and fertilizer supply is insufficient during vegetative growth, blind shoots and blind flowers easily appear. Therefore, producers are reminded that in large-scale production they should strictly select bulb specifications according to different cultivation methods.
Influence of human factors
First, when removing the bulb skin before planting, try not to damage the stem buds, to reduce the occurrence of blind shoots. Second, extreme high temperatures caused by human factors during storage and transport, such as excessive heat dissipation from the bulbs themselves or from other fruits, vegetables, flowers and engines, cause ethylene production within the bulbs. When the ethylene concentration reaches 0.1 dpm, it causes bud necrosis, and after planting a large number of blind shoots will appear.
Influence of other factors
For example, incorrect watering during cultivation, excessive humidity in the greenhouse, and disease-carrying planting stock causing root asphyxiation mean there is even less yield to speak of.
Tulip disease control (additional) pest and disease control
The pathogens of tulip pests and diseases can be carried by bulbs, or carried by soil and infect bulbs. They mostly occur in high-temperature, high-humidity environments. The main diseases include stem rot, soft rot, color-breaking disease, damping-off and blind buds, etc., and the insect pests are mostly aphids.
Control methods
Carry out thorough soil disinfection before planting, choose virus-free bulbs for cultivation as far as possible, promptly dig out and destroy diseased plants found, and water with fungicide 1-2 times during greenhouse growth for better results; maintain good ventilation to prevent high temperature and high humidity; when aphids occur, spray 3% natural pyrethrin at 800 times dilution to kill them.
Color-breaking petal disease
Tulip color-breaking petal disease, also called tulip white streak disease, occurs in all tulip producing areas and is one of the important causes of tulip bulb degeneration. The disease mainly infects tulip leaves and corollas. Affected leaves show light green or grayish-white streaks, sometimes forming a mosaic. Petals are deformed, and on single-colored flowers pale yellow or white stripes or irregular spots appear. Affected bulbs degenerate and become smaller, plants grow poorly and are stunted, and flowers become smaller and deformed. The pathogen is tulip breaking virus (Tulip breaking virus, TuBV).
The virus overwinters in diseased bulbs and becomes the source of infection the following year, and is transmitted non-persistently by the green peach aphid and other aphids. This virus can also harm lilies, and after lilies are infected they show mosaic or latent symptoms. Under natural cultivation conditions, double-flowered tulips are more susceptible to the disease than single-flowered tulips.
1. Control aphids and spray insecticides regularly to reduce transmission vectors.
2. Strengthen quarantine to control the expansion and spread of the disease. Immediately pull out diseased plants found. Avoid planting too close to lilies to prevent mutual infection.
Preventing bulb rot
In tulip cultivation, bulb rot often occurs. The main causes are: the dug-out bulbs were not dried and carry disease-carrying soil, and during storage the high temperature and high humidity are suitable for pathogens to reproduce and spread, causing the bulbs to rot; during cultivation, soil carrying pathogens (mostly Fusarium) and incompletely decomposed fertilizer are used, and the bulbs suffer pathogen damage, causing bulb rot; the potting soil is clayey, and with overwatering it causes waterlogging in the pot, causing the bulbs to rot from waterlogging; the bulbs are dug up too early, and the new bulbs are not plump enough, which also easily causes rot. The method to prevent bulb rot is to take corresponding measures according to the above causative factors.
Sclerotinia disease
After infection, yellow or brown slightly raised round spots appear on the scales, and sclerotia form in the slightly sunken inner parts. When the pathogen infects the stem, it produces long oval lesions, and sclerotia form at the soil surface. Control methods: first, disinfect the soil before planting; second, immediately pull out diseased plants after onset and spray with zineb at 500 times dilution.
Viral diseases
Viral diseases are one of the main causes of tulip germplasm degeneration. There are many viruses that harm tulips, and two are common in China: mosaic virus and breaking virus. Mosaic virus causes yellow stripes or fine speckled spots on affected leaves and dark spots on petals; in severe cases the leaves rot, so timely control of aphids and removal of weeds are important. Breaking virus causes pale yellow or grayish-white stripes or irregular spots on diseased leaves, sometimes forming a mosaic pattern, and pale yellow or white stripes or irregular spots on petals, producing broken-color flowers on red or purple varieties.
Soft rot
This disease mainly harms tulip bulbs and plants. After the bulb is infected, water-soaked brown spots begin to appear, and then the bulb becomes soft and rotted. After the plant is infected, the leaf tips and leaf margins of the lower leaves fade, the stem turns purple, the stem base shrinks, and the plant then dies. Control methods: when storing bulbs, avoid high temperature and high humidity, ensure ventilation, and avoid continuous cropping. Diseased plants and infected bulbs should be disposed of promptly. In the early stage of infection, spray promptly with a 1000-fold solution of 70% thiophanate-methyl.
Root lice
They feed on bulbs in the soil, bore into the epidermis and suck sap, causing plants to grow weakly, rot easily, or become susceptible to disease. Soak infested bulbs in dilute limewater for 10 minutes, then remove and rinse clean to kill the root lice.
Damping-off
Flower stems or plants collapse. The cause is too high relative humidity in the greenhouse, or poor rooting of the bulbs leading to reduced water uptake. Control methods: during management, do not allow temperatures that are too low, and do not let plants grow too quickly at high temperatures; ensure normal root function and avoid excessively high relative humidity (above 80%).
Blind buds
The flower bud loses water, the petals remain green, the leaf tips are white, the stamens and pistils dry up, and the flower cannot fully open. The causes are insufficient cold treatment, temperatures that are too high during storage and transport, relative humidity in the greenhouse that is too high, and improper watering methods leading to root suffocation, among others. Control methods: strictly prevent the above phenomena at every stage.
Root rot
In mild infections, part of the root system rots; severe infections cause the flowers to wilt. Infected roots usually become waxy and turn the surrounding soil brown, and eventually the entire root system turns brown. The cause is infection by Pythium. Control methods: disinfect the soil before planting. Remove heavily infected bulbs promptly. Ensure the greenhouse soil has good soil structure and a good drainage system. For the first two weeks after planting, keep the greenhouse temperature at 10°C or below.
Soft rot
In early infected bulbs, the tissue becomes soft and pink and releases a peculiar odor; in the later stage, soft rot manifests as stunted plant growth, yellowing leaf tips, and dehydration of flowers. The cause is infection by Pythium. Control methods: fully disinfect and sterilize the bulbs before planting and disinfect the soil. Ensure the greenhouse soil has good soil structure and a good drainage system. Remove infected plants promptly and disinfect the affected soil.
Scorch
Water-soaked green spots appear on flowers and leaves and gradually become large white or brown spots; in severe cases they can prevent plant development or hinder flowering. The cause is infection by downy mildew. Control methods: remove already infected bulbs before planting and disinfect the soil. Apply routine sterilization treatment to infected soil. During cultivation, keep plant leaves dry, especially at night. It is best to water directly onto the soil.
Southern blight
Symptoms: The whole plant wilts, white mycelial strands or mustard-seed-like tawny-brown small sclerotia wrap around the stem base, and the affected part turns brown, rots, and decays. Large amounts of white mycelial strands and tawny-brown fungal bodies can be seen on the soil surface.
Pathogen: Sclerotium rolfsii Sacc., called southern blight, belongs to the Deuteromycotina fungi. The hyphae are white and silky, spreading in a fan shape or radially, then gathering into mycelial strands or tangling into sclerotia. The sclerotia resemble rapeseeds, initially white to yellowish-white, later turning tawny-brown, round, with a smooth surface. In addition, it has been reported that Corticium rolfsii (Secc.) Cyrzi. is also a pathogen of this disease.
Transmission routes
The pathogen overwinters in the soil as sclerotia or mycelial strands with diseased residues. When conditions are suitable the following year, the sclerotia or mycelial strands produce hyphae for primary infection.
The silky hyphae produced by the plant extend to contact neighboring plants, or the sclerotia spread through water flow for secondary infection, causing the disease to spread and expand. The disease is severe in years or seasons with continuous cropping, heavy clay soil, low-lying terrain, or high temperature and humidity.
Control methods: When diseased plants are found, pull them out promptly and burn them. Drench the diseased holes and nearby plants with a 1000-1600 fold solution of 5% validamycin aqueous solution, or a 500-600 fold solution of 50% Tian'an aqueous solution, or a 1000 fold solution of 20% tolclofos-methyl EC, or a 500 fold solution of 90% fenaminosulf wettable powder, sprinkling and drenching 0.4-0.5 liters per plant (hole). When plowing, mix in 100-150 kg of lime powder per mu to make the soil slightly alkaline, which can inhibit the reproduction of the southern blight pathogen.
Brown spot
Symptoms: Infected leaf buds develop poorly and become deformed and curled; leaves that grow after the young buds are damaged become curled. If the environment is humid, large amounts of gray mold-like conidia are produced on the diseased tissue, affecting nearby healthy plants and causing leaf infection, so bulb growth is greatly affected. After flowers are infected, white or light yellowish-brown lesions first appear, then they quickly wither and drop, or turn brown and dry up. Ring-like bands appear on the flower stalk, sometimes with a layer of conidia on them. Every stage of the disease is highly prone to infecting flowers. Sclerotia form on the outer coat of diseased bulbs, or round to oval sunken spots appear on the outer scales, grayish-yellow in the center with brown edges, containing one to several sclerotia.
Pathogen: Tulip fire [Botrytis tulipae Lind.] belongs to the Deuteromycotina, commonly found in tulip-growing areas, and is more severe in the rainy season. Transmission routes: Mycelia and sclerotia remain in rotted bulbs and soil to overwinter. After diseased bulbs are planted, large amounts of conidia are produced on the damaged and dead young buds, which are the source of infection for aboveground diseases.
Disease conditions: The pathogen can produce conidia at 5°C and humidity of 90%-100%. The disease is severe in spring with low temperatures and rainy, humid weather.
Control methods
Remove diseased bulbs before planting and practice crop rotation.
Once buds or flower buds showing symptoms of this disease are found, remove them immediately to control disease development.
Before planting, soak the bulbs in a 2% formalin solution for 30 minutes, then dry and plant to reduce residual pathogens.
During the growing period, spray a 1000-fold solution of 50% iprodione, or a 2000-fold solution of 50% procymidone, or a 1000-fold solution of 50% dimethirimol.
Black rot
Symptoms: The bulb becomes diseased. On the stem plate and stem surface, sometimes on the 2nd and 3rd scales, irregular lesions initially yellowish-brown and later black appear, with a rough surface.
Pathogen: Pseudomonas andropogonis (Smith) Stapp, a Pseudomonas bacterium. The bacterial cells are rod-shaped, 1.9*0.8 micrometers in size, with 1-3 polar flagella. The optimum temperature for disease development is 20-25°C, with a minimum of 5°C.
Transmission routes: Infected bulbs and diseased residues in the soil are the sources of infection.
Mosaic disease
Symptoms: Mosaic-like markings and chlorotic streaks appear on leaves, sometimes necrotic spots form, and dark spots appear on petals. Growth and development are inhibited. When symptoms are severe, the corms do not grow large and the damage is great.
Pathogen: Cucumber mosaic virus (CMV).
Transmission routes: This virus occurs on many crops and weeds and is transmitted non-persistently by aphids.
Control methods:
Use healthy bulbs.
Control aphids promptly.
Fusarium wilt
Symptoms: Dark brown and gray sunken spots appear on the outer scales of the bulb, then expand into medium to dark brown lesions. If diseased bulbs are placed in a warm, humid place, white or pink mycelia and conidia grow on them, causing the infected tissue to shrink and harden. After the bulb base is damaged, rapidly developing lesions can spread across all scales; ethylene produced by diseased scales can cause healthy bulbs to exude gum, affecting growth. Leaves on the bulb show premature aging, and some leaves stand upright and gradually turn a characteristic purple. The flowers produced are thin and small, deformed, and even withered. In a greenhouse, infected plants will yellow and die prematurely.
Pathogen: Fusarium oxysporum Sch1. f. sp. tulipae Apt. Microconidia are 5-12*2.2-3.5 micrometers; macroconidia have 3-5 septa and measure 30-60*3.5 micrometers.
Control methods:
Appropriately delay planting and dig up bulbs early to avoid the high-temperature period as much as possible, so as to prevent rampant damage by the pathogen.
Store healthy bulbs separately in a ventilated, cool place (below 15°C).
Do not plant too densely, and remove diseased plants promptly during the growing period.
Within 48 hours of digging up the bulbs, soak them in a water solution of 50% benomyl wettable powder for 15-30 minutes, then dry and store.
Plant disease-free bulbs and practice a three-year rotation system.
Broken-color petal disease
Symptoms: The main symptoms appear on the flowers. On the same flower, the petal colors show varying degrees of change: some colors deepen, some remain normal, and some become lighter. Some become mottled, and some form stripes. Affected leaves show lighter-colored spots or stripes, and in many varieties the outer anthocyanin pigment of the first leaf shows irregular stripes.
Pathogen: Tulip breaking virus (Tulip Breaking Virus, TuBV); the thermal death point of the virus is 65-70°C.
Transmission routes: It overwinters and oversummers as sclerotia in bulbs and soil. During the growing period it is transmitted by aphids. The knives and scissors used when cutting flowers can also transmit it.
Control methods:
Select virus-free plants as propagation material.
Remove diseased plants promptly.
Spray a 1000-fold solution of 40% dimethoate EC, or a 1000-fold solution of 40% omethoate EC, or an 800-fold solution of 2.5% rotenone to control aphids.
When cutting flowers, the knives and scissors should be heat-sterilized or washed clean with detergent before use.
Tulip cultivar classification
There are many tulip cultivars, about ten thousand or more. Flower shapes include cup-shaped, bowl-shaped, egg-shaped, spherical, lily-flowered, and double-flowered, among others. Flower colors include white, pink, purple, brown, yellow, orange, and others, in varying shades, single-colored or bicolored. Flowering periods include early, mid, and late. Although the cultivars are extremely rich, like hyacinths they are not easy to cultivate successfully in many places in China and often degenerate.
Today, after long-term crossbreeding by horticulturists, there are more than 8,000 cultivars worldwide, of which about 150 are mass-produced. They are brightly colored and highly varied, with red, yellow, and purple being the most popular. For example, a yellow flower sprinkled with red dots on the petals is called "King's Blood"; a red flower with stripes distributed on the petals is called "Olympic Torch"; and a crimson flower with petals curling around each other is called "Lover's Hot Kiss," and so on. Carotenoids turn the petals bright orange and yellow; anthocyanins bring light pink, rose red, and deep purple; and tiny air bubbles between the petal cells give the flowers a crystalline pure white. As for black tulips, the most classic cultivar is named "Queen of Night," and its color is produced by the projection of cell protrusions. The flowers of cultivars such as "Diane's Widow," "Peerless Beauty," and "Black Queen" produced in the Netherlands are not pure black.
By flower shape variation
Cup-shaped: The corolla is cup-shaped, including Cottage tulips, Darwin tulips, and Darwin hybrid tulips;
Bowl-shaped: The corolla is shallow dish-shaped and bell-shaped, with many small flowers, including water lily tulips;
Lily-flowered: The petal tips are gradually pointed, and the corolla resembles a lily, including lily-flowered tulips;
Spherical: The corolla is spherical, being the double-flowered types among Cottage tulips and Darwin hybrid tulips.
By flowering time
Mainly based on early or late flowering, tulips are divided into: Early-flowering types. They flower early, blooming in March-April, including the Early Single series, Early Double series, Mendel series, and Triumph series; Late-flowering types. They flower late, from late April to early May, including the Darwin series, Darwin hybrid series, Breeder series, Lily-flowered series, Cottage series, Rembrandt series, Bizarre series, Parrot series, Peony-flowered series, and species and hybrids.

Although tulip cultivars are extremely rich, like hyacinths they are not easy to cultivate successfully in many places and often degenerate.
By color classification
Overall, the flower language of tulips is universal love, consideration, elegance, wealth, capability, and intelligence.
1. Tulip (red) Tulipa gesneriana, Liliaceae, Tulipa
The tulip is the national flower of the Netherlands. From 1634 to 1637, there was a period known in Dutch history as "Tulip Mania." New and rare tulip cultivars were bought and sold at high prices and became investment objects that people raced to pursue.
Flower language: confession of love
Gift-giving etiquette: Place several stems of red tulips on square stiff backing paper, fix their positions with tape, carefully wrap them in transparent plastic paper, and decorate the four corners with golden ribbons to add a sense of elegance.
2. Tulip (yellow) Tulipa gesneriana, Liliaceae, Tulipa
In Europe and America, yellow flowers are usually not very popular, and their related flower languages also carry relatively negative meanings. In fact, clear bright yellow contains the joy of spring; how could such eye-catching bright flowers fail to inspire affection?
Flower language: hopeless love
Gift-giving etiquette: Because tulip flower stems have a rather graceful curve, it is best to use slightly larger white patterned wrapping paper; tie 4-5 long stems into a bunch, and the ribbon must be yellow.
3. Tulip (white) Tulipa gesneriana, Liliaceae, Tulipa
Origin of the name: When an Australian ambassador who came to Turkey in the 16th century first saw this flower, he asked the Turks around him for its name, and the answer was: tulip. In fact, this pronunciation referred to a Turkish turban; that Turk misunderstood the ambassador's meaning, but the flower name was thus produced and has continued to be used.
Flower language: love that has passed
Gift-giving etiquette: Simply make a bouquet with just a few white tulips, without adding other embellishments. Wrap the outside with pink gauze, then gently tie it with a few thin red ribbons.
Hybrid cultivation
After long-term crossbreeding by horticulturists, there are more than 8,000 cultivars worldwide. About 150 are mass-produced, among which red, yellow, and purple are the most popular.
The new cultivar Guotai tulip was discovered by the Dutchman Jan Carol in 1999; the whole flower is dark purple, feather-like, and parrot-shaped. On March 24, 2014, China's First Lady Peng Liyuan, invited by the Dutch royal family, named this new purple parrot-shaped tulip "Guotai." "Guotai" gives this purple tulip the new connotations of world peace, national prosperity, and people's well-being. It has now become a flower used for national foreign affairs activities, large celebrations, Chinese and foreign flower exhibitions, high-end hall decoration and display, and high-standard ceremonial gifts.
A yellow flower sprinkled with red dots on the petals is called "King's Blood"; a red flower with stripes distributed on the petals is called "Olympic Torch"; and a crimson flower with petals curling around each other is called "Lover's Hot Kiss," and so on.
Carotenoids turn the petals bright orange and yellow; anthocyanins bring light pink, rose red, and deep purple; and tiny air bubbles between the petal cells give the flowers a crystalline pure white.
As for black tulips, the most classic cultivar is named "Queen of Night," and its color is produced by the projection of cell protrusions. The flowers of cultivars such as "Diane's Widow," "Peerless Beauty," and "Black Queen" produced in the Netherlands are not pure black.
Species and hybrids:
Koufmaniana varieties and hybrids, also called water lily-flowered type: the corolla is bell-shaped, the flowering period is early, and the leaves often have stripes.
Fosteriana varieties and hybrids: The leaves are broad with obvious purplish-red stripes, and the corolla is cup-shaped.
Greigii varieties and hybrids: The species leaves have purplish-brown stripes, the corolla is bell-shaped, and the flowers of hybrids with Darwin tulips are extremely large.
Other species, varieties, and hybrids: such as Tulipa pulchella, Tulipa clusiana, Tulipa acuminata, Tulipa tarda, etc.
Artificially Hybridized Varieties
The tulip is a hybrid produced through nearly a century of artificial crossbreeding involving multiple parent plants, with as many as 8,000 cultivars. Flower shape, flower color, blooming period and plant form vary greatly. In 1981, tulips were classified abroad into 4 classes and 15 groups.
I. Early-flowering class:
Single Early Group: plant height 20-25 cm.
Double Early Group.
II. Mid-season flowering class:
Triumph Tulip: large flowers, single, plant height 45-55 cm.
Darwin Hybrid Group: large flowers, cup-shaped, bright flower colors, plant height 50-70 cm.
III. Late-flowering class:
Single Late Group: plant height 65-80 cm, cup-shaped flowers, relatively many cultivars, many flower colors, such as Queen of Night which is purple, etc.
Lily-flowered Tulips: petal tips pointed, opening flat, shaped like a lily.
Fringed Tulips: petal edges have crystalline fringed borders.
Viridiflora Tulips: part of the perianth turns green.
Rembrandt Tulips: the corolla has differently colored streaks.
Parrot Tulips: petals twisted, with jagged fringes.
Double Late Tulips, also called Paeony Flowered Tulips.
IV. Botanical Species and Hybrids:
Koufmaniana Varieties and Hybrids, also called the water lily type: corolla bell-shaped, early blooming, leaves often striped.
Fosteriana Varieties and Hybrids: leaves broad with obvious purplish-red stripes, corolla cup-shaped.
Greigii Varieties and Hybrids: the original species has purple-brown striped leaves, bell-shaped corolla; the hybrids with Darwin tulips have extremely large flowers.
Other species, varieties and hybrids: such as Tulipa pulchella, Tulipa clusiana, Tulipa acuminata, Tulipa tarda, etc.
Among the above groups, groups 1 to 11 were formed after multiple hybridizations, namely the common tulips. Groups 12 to 15 are wild species, varieties or hybrids, whose original species characteristics remain obvious, so the parent species names are still used as the group names.
The Distribution Regions of Tulips
The tulip originates from the high mountain regions of **Tibet, China, Iran and Turkey. This species is a widely cultivated ornamental flower, and because of its long history, it has many cultivars.
The tulip's places of origin include the north and south coasts of the Mediterranean and Central Asia, as well as Iran, Turkey, and eastward to Northeast China and other places. The exact origin is difficult to verify, but it is now mostly believed to originate from Ceylon and the direction slightly southwest of the Mediterranean. Today tulips are commonly planted in every corner of the world, among which cultivation is most prevalent in the Netherlands, becoming a commercial production. They are also widely cultivated in gardens throughout China.
China's tulip resources are mainly concentrated in the northwest region. On the wastelands and hills of **, the most commonly seen is the ** tulip that blooms yellow flowers in early spring. The most widely distributed wild tulip in China is the Chinese tulip (Amana edulis); it can be seen on hillsides and even in parks in East China and Central China.
In 1593, the first tulip bulb was imported from Constantinople (that is, Turkey) by a Dutch merchant named Guesters. Later it was widely cultivated in China.
The Landscape Uses of Tulips
The tulip is an important spring bulbous flower, suitable for cut flowers or for arranging flower beds and flower borders, and can also be planted in clumps on lawns or under the shade of deciduous trees. Medium and short varieties can be potted. In gardens they are mostly used to arrange flower beds or planted in masses on lawns, in woods, and by water, forming overall color-block landscapes.
The Functions and Uses of Tulips: Ornamental Value
The tulip is a world-famous bulbous flower and also an excellent cut flower variety. The flower is vigorous and upright, the leaves are elegantly plain in color, and the lotus-like flowers are dignified and moving, endearing to people. In Europe and America it is regarded as a symbol of victory and beauty, and many countries such as the Netherlands, Iran and Turkey treasure it as their national flower.
Potted Plant Use
The tulip's flowers resemble lotus flowers, with many flower colors, rich and brilliant in color. It is a world-famous bulbous flower. In European and American novels and poetry, it is regarded as a symbol of victory and beauty, and can also represent grace and elegance. It is suitable for embellishing courtyards, as cut flowers and for potting.
In China, tulips have three main uses:
1. Landscape exhibition arrangement
The characteristic of tulips is that when a single variety is cultivated on the same plot, its flower stem length, blooming time, flower color and flower shape are very uniform, which is the main reason they are generally welcomed; secondly, the flower colors are rich and brilliant; thirdly, the flowers are large with unusual traits; fourthly, there are many cultivars, and different cultivars differ in flower color, flower shape, flower posture, plant height, leaf shape and leaf color. In garden applications, tulips can satisfy a great variety of requirements and artistic approaches. From deep in the woods to open lawns, whether by ponds and lakesides or by rockeries and pavilions; whether Western-style geometric flower beds or Chinese-style small bridges and flowing water, winding railings and secluded paths, one can choose and arrange scenery that is in perfect harmony with nature. Hangzhou's Taiziwan Park has held a tulip flower show every year since 1993, achieving good benefits. Every April, when the tulips in Taiziwan Park are in bud and in full bloom, the park is packed with people, attracting a large number of Hangzhou citizens and out-of-town tourists, not only achieving very good social benefits but also very good economic benefits, and greatly expanding the park's fame.
2. Supplying cut flowers and potted flowers during the Spring Festival
The beautiful tulip is a wonderful flower indispensable to people's lives. During festivals such as Christmas, the Spring Festival and Valentine's Day, giving a bouquet or a pot of vigorous, spring-filled tulips will add boundless affection to the festival.
Feng Shui Function
It is beneficial to the love luck of people whose Five Elements belong to earth. People born in the Year of the Ox have the Five Elements belonging to earth, and the tulip is their lucky flower. They are emotionally rich and clear in their loves and hates, and should seek balance through the golden mean. In love life there are sometimes ups and downs, especially when women place their feelings on entertainment in the outside world, causing disagreements in the family; this must be overcome, and couples must eliminate suspicion. For such a tortuous love life, if you plant your own lucky flower, the tulip, at home, it can improve your love luck to a certain extent. In addition, planting tulips at home can also improve their fortunes. Heaven's blessing and good luck protect people born in the Year of the Ox to turn bad luck into good, and Heaven's blessing and good luck shelter those born in the Year of the Ox to see their luck turn.
The feng shui function of the tulip comes from its fragrance. We know that the fragrance of the tulip can kill bacteria in the air. Bacteria grow in the air, and after we breathe them in we feel discomfort and may even fall ill. If the tulip washes away these harmful components, it reduces the chances of discomfort and illness [16]. At the same time, it can carry out photosynthesis, inhaling a large amount of carbon dioxide and releasing fresh air. If the carbon dioxide content in the air is high and oxygen is lacking, we will feel short of oxygen and our minds will not be clear. If the tulip balances the indoor atmosphere and restores it to a normal state, we can live healthily. A home feng shui in which one can live healthily and happily is the good-feng-shui home we hope for. From this it can be seen that a good-feng-shui home comes from the tulip.

Tuliposide ABC has an inhibitory effect on Bacillus subtilis. After tulip juice passes through cation and anion exchange resins, it still has an antibacterial effect on Staphylococcus aureus. The alcohol extract of stems and leaves has an antibacterial effect on Bacillus cereus mycoides, and its active components contain a variety of amino acids.
Pharmacological Effects
Tulip flowers contain cyanidin bis-glucoside, salicylic acid and arginine; the pistil, stems and leaves contain the antibacterial tuliposide A, tuliposide B and a small amount of tuliposide C. Tuliposides A and B can partially convert after standing into inactive 6-tuliposide A and 6-tuliposide B. The buds contain gibberellin A1.

The Origin of the Name Tulip
The tulip originated in the Middle East and was introduced to Europe in the 16th century. In the Middle East, people always associated it with the Muslim turban. Because its flower resembles a Muslim turban, Persian called it dulband, and Turkish borrowed it as tulbend, meaning "Muslim turban." The word entered English through French tulipe/tulipan and Latin tulipa, evolving into the form tulip. The Turkish word tulbend entered English through another channel as turban, still meaning "Muslim turban."
The Cultural Background of Tulips: "Greigii" Tulips Make Their First Appearance in the Capital
Right now, in Beijing's Zhongshan Park, green leaves with black spots set off magenta and orange-yellow tulips with white edges, attracting many tourists. These 20 cultivars of "Greigii" tulips introduced from the Netherlands are making their first appearance in the capital. The 10th Large-scale Tulip Flower Show of Zhongshan Park, with the theme "Return to Nature," opened on April 21 and will successively display more than 60 cultivars and 300,000 tulips. According to park engineer Meng Lingyang, at this flower show, in addition to some conventional cultivars such as 'Orange Bouquet', 'Happy Time' and 'Manner', 20 new cultivars of the "Greigii" type have been added, such as 'Dream Boat', 'Marianne' and 'Yellow Dawn'. The characteristics of this type of tulip are early blooming, large flowers and short plant form. These tulips have different blooming periods, with the latest blooming in early May. The layout of tulips in the park is divided into two types: formal and naturalistic. The formal style is generally arranged in a matrix shape. The naturalistic style combines the park's terrain, gives play to creativity, and is randomly placed to achieve a landscape effect in harmony with the environment.
Related Legends
When tulips are mentioned, one invariably thinks of the tulip kingdom, the Netherlands, yet it was actually the Turks who first planted tulips. The Netherlands' ability to become today's tulip empire should be credited to the director of the Vienna royal herb garden in the 16th century. For religious reasons, this herb garden director moved to the Netherlands, and at the same time brought in the European tulips he had cultivated.
Legend One
In ancient Europe, there was a beautiful maiden who was courted and pursued by three handsome knights at the same time. One gave her a crown; one gave her a sword; another gave her gold. The maiden was very worried and did not know how to choose, because all three men were so outstanding, so she had no choice but to ask the flower god for help. The flower god then turned her into a tulip: the crown became the flower bud, the sword became the leaves, and the gold became the bulb. In this way she accepted the love of the three knights at the same time, and the tulip also became the embodiment of love. Because the crown represented incomparably noble status, the sword was a symbol of power, and possessing gold meant possessing wealth, in ancient Europe only nobles and celebrities were qualified to plant tulips.
Legend Two
Originally there was no purple in the world. One day, no one knew who blended red and blue together, and so magical purple appeared...
In fact, long ago, tulips had only one color - white. Because in their family, white was the noblest and purest. Finally one day, a prince passed by them. When the prince bent down to caress their petals, they were instantly stunned. His deep purple pupils emitted a faint glow, and a light purple robe set off his extraordinary temperament. The most dazzling thing was the amethyst ring on his hand; although it was very small, it seemed to possess magical power. They were clearly lucky: the prince, disregarding the obstruction of his attendants, carefully dug them out of the soil with his own hands and brought them back to the imperial palace. From then on, they lived in a fantasy world full of purple, praying that one day their own petals could also turn purple.
In the end, she who stopped at nothing won the prince; while she who was kind gave everything, yet ultimately chose to give up. In the woods, her sword pierced in from her chest, and fresh blood gushed out. The prince awoke as if from a dream and hugged her, crying bitterly. At that moment, she smiled, smiling so brightly, so beautifully... Her fresh blood flowed on this black soil, shimmering in the sunlight with a faint purple light, that weak yet soul-stirring purple light!
From then on, a strange and beautiful flower appeared in the world - the purple tulip. Old people say that it represents love that will never be erased.
Tulip Allusions
Tulip Allusion One:
Tulips were introduced to Europe from Turkey in 1554 and immediately became popular. By the 17th century they had become the target pursued competitively by crazy financial speculators in the Netherlands. Someone even made up a story: in ancient times a beautiful maiden lived in a majestic castle, and three warriors fell in love with her at the same time. One gave her a crown; one gave a sword; one gave a pile of gold. But she favored none of them, so she had no choice but to pray to the flower god. The flower god felt deeply that love cannot be forced, so he turned the crown into flowers, the sword into green leaves, and the pile of gold into bulbs, and together these became the tulip. Every Valentine's Day, for young men and women expressing love, besides roses, tulips have also become the best choice for conveying affection to a lover. This story further deepened the Dutch people's impression of this flower. Some media even promoted a maxim: "Whoever belittles the tulip has offended God."
Finally a "tulip mania" swept across the whole Netherlands and even Europe. Many people believed that "a rich man without tulips is not truly rich." Some people would even rather exchange a winery or a house for a few rare bulbs. In 1637, the Dutch tulip market collapsed, and in the end the government intervened to stop further speculation.
During the crazy speculation period, the number of tulips on the financial market exceeded the number actually planted, but these many "madman's dances" made the Netherlands rich. At the beginning of the 19th century, the whole Netherlands planted only 130 acres of tulips; by the middle of the 20th century this had grown to more than 20,000 acres, accounting for more than 80% of the world's total tulip exports, sold in 125 countries, and it was praised as the "queen of flowers of the world." The emergence of this super flagship product made the tulip deservedly become the national flower, and also deservedly be designated, together with windmills, cheese and wooden shoes, as one of the "four national treasures."
Tulip Allusion Two:
During World War II, in one winter the Netherlands suffered a famine, and many starving people ate tulip bulbs as food and relied on tulips to stay alive. Grateful for the tulip's life-saving grace, the Dutch made the tulip their national flower.
Tulip Allusion Three:
In ancient Roman mythology, the tulip was the daughter of the god Bratus, who, in order to escape the one-sided love of the autumn god Belzenu, asked Diana, the goddess of chastity, to turn her into a tulip flower. Therefore, one meaning of the wild tulip is chastity. Of course, what different colors of tulips represent is different.
Related Poetry
The great Tang Dynasty poet Li Bai once wrote a famous poem, "Traveling as a Guest":
Lanling fine wine with tulip fragrance, served in jade bowls shining with amber light.
But if the host can make the guest drunk, he will not know where his native place is.
The Lanling fine wine mentioned in the poem, due to the development of brewing techniques, should have been different from today's wine; the so-called "tulip" should refer to its having the fragrance of the spice and medicine "turmeric." The "tulip" wine described in the original poem has in fact long been lost to later ages.
But it was precisely inspired by this poem that around the Ming Dynasty a wine named "Tulip" appeared. The "Tulip" wine of Lanling Town in Cangshan County, Shandong Province and of Nanxiang Town in Jiading District, Shanghai are both quite famous.
Tulip wine is brewed from polished white rice after traditional fermentation, combined with more than twenty medicinal materials such as turmeric, angelica and eucommia. The wine is purple-red and transparent, with high concentration; when drunk it is mellow and fragrant, sweet with a slight sourness and a faint medicinal taste; with sugar added it is moderate (25 degrees), and the alcohol content is low (20 degrees), so it is naturally deeply welcomed by men. It is said that women also love to drink it, hence it has the name "madam's wine." (Note: the turmeric referred to in traditional Chinese medicine does not mean the flower of the tulip or the bulb of the tulip. The turmeric referred to in traditional Chinese medicine is a plant of the ginger family.)
Wuhan, a Holy Land for Viewing Tulips
At the Tulip Flower Festival held by the Wuhan Botanical Garden of the Chinese Academy of Sciences, a total of 5 exhibition areas were set up, and the blooming periods of early, middle and late tulip cultivars in the garden overlapped, and some areas arranged relying on water areas welcomed their best viewing period. For example, the scenic spot named "Top of the Rainbow" in the Lianxuan Lake shore area close to the chrysanthemum nursery has yellow, red, white and purple tulips distributed in strips; flowers set off the water and the water reflects the flowers, like a rainbow fallen to the earth, with flower shadows flickering in the water, delicate flowers mirrored in the water in perfect harmony. Wuhan launched a Wuhan flower-viewing map to make things convenient for tourists. In mid-spring, besides 600,000 tulips blooming delicately, peach blossoms, pear blossoms and camellias also appeared one after another, and daffodils, irises, azaleas, peonies and Chinese peonies were also unwilling to lag behind in displaying their beauty.
The understory exhibition area at the garden's entrance is the site where, in 2013, a tulip scene was arranged for the first time in imitation of the Keukenhof Park in the Netherlands. Relying on the small river flowing through this area, the garden authorities created a 60-meter-long, 5-meter-wide "flower stream," whose role is like the "Blue Danube" flowing through Keukenhof Park. The white tulips in the "flower stream" have already opened, and the blue grape hyacinths have also successively entered their blooming period. It is expected that this weekend one can see the beautiful scene of alternating blue and white, swaying gracefully.
Wuhan Dutch Style Garden
The garden has planted many large tree varieties reflecting Dutch style, and Dutch-style ground cover plants have been laid out over a large area. The whole garden added more than 2,000 trees in total and 24 kinds of shrubs (including flowers). The flower varieties are full of "Dutch flavor." Tulips and hyacinths are the most famous flowers of the Netherlands; in the flower fields, 22,000 pots of tulips and 6,500 hyacinths have been arranged, with red, pink and blue all available.
**
The 4th Tulip Festival will open at Qinggeda Lake in Wujiaqu City. At that time, 1.2 million tulips of 125 cultivars will give off their fragrance and adorn the spring scenery of Qinggeda Lake. Qinggeda Lake tourism, with the theme "Colorful Tulips, Charming Wujiaqu," will also be held at the same time.
According to Jiao Mingqi, Party Secretary and Political Commissar of Wujiaqu City of the Sixth Agricultural Division, the annual Tulip Festival has become a bright calling card for Wujiaqu City. Compared with previous editions, the 2013 Tulip Festival is large in scale and high in quality. The tulips in bud and blooming include the delicate beauty of goose yellow, the passion of fiery red, the purity of snow, and the nobility of purple-black, complementing the rippling blue waves of Qinggeda Lake.
Kunming
Cuihu Park, Kunming: the sunshine is always warm and genial, and the sky appears especially blue. The long-term mild and moist air makes this place the best residence for tulips. Vast expanses of flower fields stretch beyond sight: bright red, tender yellow and purple-white flowers float like clouds and mist! Famous tulip cultivars such as "Apollo," "Golden Apollo," "Merry Christmas" and "Apollo Beauty" bloom with reserve and freedom from vulgarity; some are brilliant like peonies, some are concise like azaleas, and some are so full that they bend the branches...
Xining

The Tulip Bubble Economy
In 1593 a Dutch merchant named Guesters imported the first tulip bulb from Constantinople (Turkey) and planted it. Because this flower was an imported good, owning a tulip became a symbol and special honor of the wealthy. Rich people had to own tulips to count as rich, so buying tulips became a symbol for the rich to display their wealth, and thus this trend spread from the Netherlands to Germany. As it happened, at this time tulips were infected with an infectious disease called Mosaic, which made the tulip petals more vivid, so virus-infected tulips were even more sought after, forming a wave of panic buying.
At first, only tulip connoisseurs knew how to appreciate the beauty of tulips, but after the trend formed, people bought tulips only to make money. As the wave of panic buying gradually formed, speculators took the opportunity to hype them: as long as you bought today, you could earn a sum tomorrow, and it worked every time. Because more people bought, a trading market formed, and trading venues gradually became lively, like a stock trading market.
In 1634, the craze for buying tulips spread to the middle class and even spread to become a movement of the whole people. Everyone came to buy and sell tulips. Speculators saw only buying low and selling high, and profit came in, so the whole people became tulip speculators. Every household poured out the family fortune just to buy one tulip. A tulip bulb cost 1,000 US dollars, and less than a month later it became 20,000 US dollars. With such huge profits, no wonder everyone was dazzled; instead of doing proper work, they could just busy themselves every day with buying and selling tulips.
By 1636, tulips were listed on the stock markets of Amsterdam and Rotterdam, and tulips were even traded in some nearby European stock markets. What is more, some stock markets even introduced options, and at the same time split them into small shares, lowering the threshold for speculators, so that speculators could buy a fraction of a tulip, increasing the ease of trading. Because of the options, the price was pushed up again. Originally an actual purchase within one month could yield a 20-fold profit; through options, the profit could be magnified 100-fold.
When the madness reached its peak, one large holder sold everything and made a big profit. At the same time, the Dutch government began to take braking action, and the tulips shipped from Turkey were also about to arrive in large quantities. Suddenly, tulips were no longer so rare, and in an instant the price of tulips slid downward. Once the slide began, within six weeks it actually fell by 90%, and so there was wailing everywhere and wealth dreams were shattered. At this time, no matter how much the government tried to support the market, it could not save it. The price of tulips continued to probe new lows, and many stock market deliveries could not be completed. The Dutch government then declared this event a gambling matter, exempted delivery, and ended this crazy tulip bubble event.
Legend has it that the trigger that caused the "tulip mania" to collapse came from a foreign sailor. The newly arrived sailor mistook a bulb worth a fortune for an onion and ate it together with salt herring. The owner of the bulb demanded that the sailor pay high compensation, and after the matter was brought to court, the judge's ruling was: the inflated price of tulips was caused by speculation and could not represent the tulip's own value. This accidental event was like dropping a bomb, causing speculators to begin reflecting, and then some began frantically selling off, and the inflated price of tulips eventually collapsed like a bursting dam. To this day, with the Dutch tulip craze as a typical case, economics calls the bubble-like surge caused by speculative activity, followed by a sharp fall and crash, the "tulip phenomenon."
It took ten years after this for the Dutch economy to slowly recover. A tulip worth 76,000 dollars at its peak was worth only one dollar six weeks later. This is the first recorded bubble event in history.
Tulip as a national flower and city flower
The tulip is the national flower of the Netherlands. In addition, the tulip is also the national flower of Turkey, Hungary and Iran.
The origin of the Netherlands' national flower
The tulip originally grew on the Qinghai-Tibet Plateau in China and was introduced to Europe from Turkey in 1554. From then on it immediately became popular, and by the 17th century it had become a target pursued by frenzied financial speculators in the Netherlands. Someone even made up a story: in ancient times a beautiful maiden lived in a majestic castle, and three warriors fell in love with her at the same time. One gave her a crown; one gave her a sword; one gave her a pile of gold. But she favored none of them, so she prayed to the flower god. The flower god felt deeply that love cannot be forced, so the god turned the crown into blossoms, the sword into green leaves, and the pile of gold into a bulb, and together these became the tulip. Every year on Valentine's Day, for young men and women expressing love, besides roses, tulips have also become the best choice for conveying affection to a sweetheart. This story further deepened the Dutch people's impression of this flower. Some media even promoted a motto: "Whoever despises tulips offends God."
Finally a "tulip mania" swept across the whole Netherlands and even Europe. Many people believed that "a rich man without tulips is not truly wealthy." Some were even willing to trade a brewery or a house for a few rare bulbs. In 1637, the Dutch tulip market collapsed, and in the end the government intervened to stop further speculation.
During the period of frenzied speculation, the number of tulips on the financial market exceeded the number actually planted, but these many "frenzied dance tunes" made the Netherlands rich. At the beginning of the 19th century, the whole Netherlands planted only 130 acres of tulips. By the middle of the 20th century, this had grown to more than 20,000 acres, accounting for more than 80% of the world's total tulip exports, sold in 125 countries, and it was hailed as the "queen of flowers." The emergence of this super flagship product made the tulip unquestionably worthy of being the national flower, and also worthy of being designated, together with windmills, cheese and wooden shoes, as one of the "four national treasures."
Another account holds that during World War II, in one winter the Netherlands suffered a famine, and many starving people ate tulip bulbs as food and survived by relying on tulips. Out of gratitude for tulips saving their lives, the Dutch made the tulip their national flower.
