I. Preventing and treating root rot:When potted flowers and trees suffer from poor structure of the potting nutrient soil, alkalinity, or waterlogging, root rot and yellow leaves result. When repotting and changing the soil, the rotten roots can be cut off and the wounds coated with sulfur powder to promote new root growth.
Preserving cuttings from rot: When propagating camellia, azalea, gardenia, crabapple, southern magnolia, osmanthus and others from cuttings, the base of the cuttings can be dipped in sulfur powder before planting, which effectively prevents the cuttings from rotting.
II. Preventing and treating diseases:For flowers and trees with powdery mildew, anthracnose, black spot, gray mold and the like, spray sulfur powder in the early morning when the leaf surface is moist; in dry weather, use a sulfur powder suspension or lime sulfur mixture spray. Sulfur powder has a special effect on controlling powdery mildew, rust and so on.
Adjusting pH: For flowers that like acidic soil, applying a certain amount of sulfur powder to waterlogged, compacted or alkaline garden soil or potting nutrient soil can adjust the soil pH, reduce salinity and alkalinity damage, and prevent root rot and nutrient deficiency.
Increasing grafting success rate: After grafting succulents, spraying sulfur powder on the graft union can prevent the union from rotting due to infection by pathogens.
The role of cactus: cactus cultivation methods
Cactus is a plant of the genus Opuntia. Also known as xianbazhang, Guanyin palm, bawang, huozhang and so on, it is a plant of the family Cactaceae. Cactus is a clumping succulent shrub, with the upper branches broadly obovate, obovate-elliptic or nearly round; flowers radiate-shaped, receptacle obovate; seeds numerous, flat-round, with slightly irregular edges, hairless, light yellowish-brown. Cactus likes strong light, tolerates heat, drought and barren conditions, and has tenacious vitality; the optimum growth temperature is 20-30°C. It is mainly distributed in the southern and southeastern coastal areas of the United States, the West Indies, Bermuda, northern South America, southern China and Southeast Asia and other tropical and subtropical arid regions.
There are many kinds of cactus; worldwide there are 70-110 genera and more than 2000 species, which can be specifically divided into: prickly pear cactus types, segmented cactus types, crab claw cactus (crab cactus), leaf-type forest cactus types, and spherical cactus. They often grow in dry environments such as deserts, and are called the "hero flower of the desert"; they are a category of succulents. Below, let us take a look at the classification, roles and cultivation methods of cactus.
Classification of cactus
There are many kinds of cactus, which can be specifically divided into eight major categories: prickly pear cactus types, segmented cactus types, crab claw cactus (crab cactus), leaf-type forest cactus types, spherical cactus types, spherical cactus types, climbing cactus types, and edible cactus.
Prickly pear cactus types
They are mainly distributed in Canada, the West Indies and southern Argentina, and are the second largest family of Cactaceae plants. Their appearance varies greatly; some grow together in clumps like shrubs, while others can grow to a height of about four meters. The areoles of this genus are very large, and the colors also vary with different varieties; among the more common spines are the golden-yellow spines of the golden ball cactus, and the white spines of the white ball cactus.
Segmented cactus types
Most cacti of the segmented type grow in forests. Because there is more water in their growing environment, they do not have fat stems for storing water; instead, they have segmented stem structures, and each stem segment is relatively short.
Crab claw cactus (crab cactus)
The fleshy stem of the crab claw cactus is divided into segments, which is one of its characteristics, and this is also a characteristic of epiphytic cacti. Its flowers are relatively long, and the sepals are also colored, just like petals; during the flowering period, the flowers all grow at the ends of the fleshy stems, so the more branches a plant has, the more flowers it produces. After the flowers of the crab claw cactus are pollinated by insects, they will bear fruit, but the fruit needs a full year to fully mature; the mature fruit contains many black seeds, tastes sweet and refreshing, and can be eaten.
Leaf-type forest cactus types
Like the segmented cactus types, leaf-type forest cacti are cacti that need relatively more water. In their native habitats they grow attached to trees in forests. In fact, although the spines of some leaf-type forest cacti have degenerated, they still have areole structures. As the name suggests, the stems of this type of cactus look like long leaves, with very long segments or even no segmentation.
Spherical cactus types
The plants of spherical cacti are all round and ball-shaped in appearance, but under long-term cultivation, some varieties will deform and tend toward an oval shape; in addition, most of them do not have tubercles, and even if they do, they are very inconspicuous.
Climbing cactus types
Climbing cacti all have aerial roots and can climb on rocks or tree trunks, which is one of the characteristics of this type of cactus; they are all cylindrical and grow by climbing upward or hanging downward.
Many people say that cactus has a disinfecting and sterilizing effect, so they keep several pots at home, and when a family member has symptoms such as stomachache, they pick some to eat as medicine. Medical experts clearly point out that these cacti contain toxins, and instead of curing illness, they may actually worsen it; they must never be eaten casually.
In people's impression, cactus is not only a flower and plant, but also a kind of good medicine for treating illnesses; for minor ailments such as wound inflammation, abdominal pain and diarrhea, just eating some cactus can cure them. Now the market and restaurants also sell cactus and dishes made with it as an ingredient, and people welcome this very much, rushing to try it.
According to relevant experts, most of the cacti seen now are wild, and their original purpose is only for ornamental use. These cacti generally contain a certain amount of toxins and anesthetics; regular consumption can cause nerve paralysis, and other toxic side effects are still under further testing.
Edible cactus
Edible cactus is a newly introduced health vegetable in China in recent years. At present, the main variety is the "Mibangta" edible cactus introduced from Mexico. The "Mibangta" edible cactus is a new cactus variety selected and bred by Mexican experts over many years, mainly for eating and with multiple uses. After more than two years of introduction, demonstration, promotion and application by the high-quality agricultural products center of the Ministry of Agriculture and the Ningde region, as well as analysis and verification by nutrition experts, it is a new type of health vegetable variety suitable for planting and promotion in China. At the same time, it also has great value in medicinal, ornamental, fruit, beauty and environmental protection aspects.
The flower language of cactus
The flower language of cactus is - strength.
The cactus has a heart that is hard on the outside and soft on the inside. At the beginning of creation, the cactus was the most delicate thing in the world; she was as tender as water, and a light touch could cost her her life. God could not bear it, so he added a suit of armor over her heart, hard as iron, with sharp steel spines that could wound. From then on, no one could see the heart of the cactus anymore, and any creature that came near her would be covered in blood. Long afterward, a hero wanted to eradicate this evil thing; with the drawing of his sword, the cactus was split in two, and from within came green liquid. It turned out that this was the sealed heart of the cactus; because no one understood its loneliness, it turned into drop after drop of tears, and the green tears made the delicate cactus highlight her strength even more. Therefore, the flower language of cactus is - strength.
The role of cactus in the home environment
Plants of the family Cactaceae have very strong drought and high-temperature tolerance, and also have few pests and diseases and do not need frequent fertilizing. In recent years, people have also discovered that they have the function of reducing air pollution and purifying the air: the stomata on their fleshy stems close during the day and open at night, absorbing carbon dioxide and producing oxygen, increasing the concentration of negative ions in indoor air.
The feng shui role of cactus placement
Placement location: Cactus is best placed on a balcony, second best in an office, and worst in a bedroom.
Placed in an office, it has the effect of guarding against petty people and increasing self-defense ability. It is often used to neutralize negative energy, but it is not known that while neutralizing the negative energy of the other party, it may also cause unnecessary backlash against oneself. If there are small children or elderly people at home, it may have a slight effect on them.
Spiny cactus balls are not suitable for placement in the bedroom, otherwise they will invite disputes.
The role of cactus
The edible use of cactus
People often think that cactus is only an ornamental plant and has no use, but this is not so. In fact, the fruits of many cactus plants can not only be eaten raw, but can also be used to make wine or dried fruit. Cactus has traditionally been a food of the Americas, an indispensable specialty vegetable and fruit in people's daily lives. People wash and chop cactus and cook it in soup, or roast it over a fire, or make it into pie filling, or directly pickle fresh cactus, and some use cactus to make wine. In Mexican markets, the tender stems of some flat-padded cacti can be sold as vegetables. The woody trunks of some columnar cacti have long been used by Indigenous peoples as building materials. The flat stem segments of cactus can not only be used as livestock feed, but its viscous sap can also be used as a purifying agent to clean water quality. In some places, densely spiny cacti are planted beside houses and fields as thorn hedges.
The medicinal use of cactus
In every 100 grams of edible cactus, there are about 220 micrograms of vitamin A, 16 milligrams of vitamin C, 1.6 grams of protein, and 2.7 milligrams of iron, and it can produce 25 kcal-30 kcal of heat. In recent years, many countries have begun using cactus to treat arteriosclerosis, diabetes and obesity, and have achieved very good results. It is said that this is mainly because the vitamins contained in cactus can inhibit the absorption of fat and cholesterol and can slow the uptake of glucose. Edible cactus is very rich in nutrition; it contains a large amount of vitamins and minerals and has the effects of lowering blood sugar, blood lipids and blood pressure. The tender stems of edible cactus can be eaten as vegetables, the fruit is a sweet and refreshing fruit, and the old stems can also be processed into health products and medicines with effects such as removing blood lipids and lowering cholesterol. Mexico's pastries, snacks and dishes are widely praised, and they are cooked using the flowers of local cactus plants.
Cactus cultivation methods
(1) Watering and spraying
Terrestrial cacti have obvious growth periods and dormancy periods. They should be watered during the growth period, and watered less or even not at all during the dormancy period. For epiphytic types, if the winter temperature is kept above 12°C, they can be watered and sprayed all year round; if the winter temperature is kept below 12°C, watering can be reduced as appropriate and spraying should be stopped. When watering, grasp this principle: "water thoroughly when dry, do not water when not dry"; the water temperature should be as close as possible to the soil temperature; in summer, water early (before sunrise) and late (after sunset), and in winter water from 10 a.m. to 11 a.m.; and pour the water directly onto the potting soil, otherwise it will affect the beauty of the spines. In addition, in summer it is necessary to sprinkle water on the ground to increase air humidity.
(2) Fertilizing
For fertilizing, grasp this principle: timely, appropriate amount, and according to the object. Fertilizing is carried out in spring and autumn, once every 20 days, and should be chosen in the early morning or evening of a sunny day. If the potting soil is relatively dry, sprinkle a little water on the potting soil before fertilizing; a concentration of 0.05%-0.2% is appropriate, and watering once thoroughly the next morning gives an even better effect. Terrestrial types require fertilizers rich in potassium and phosphorus and low in nitrogen, while epiphytic types require more nitrogen fertilizer.
(3) Light
Terrestrial types prefer sufficient sunlight, especially in winter they need full sunlight exposure. Generally, tall columnar and flat-padded cacti are more tolerant of strong light and can be placed outdoors in summer without shading; smaller spherical types mostly prefer semi-shade conditions in summer. In the high-temperature summer months of June to August, cover the growth point at the top of the golden barrel cactus and its surroundings with a round piece of plastic film so that all parts of the ball grow evenly. Epiphytic cacti require semi-shade conditions all year round.
(4) Temperature
The optimum growth temperature for cactus is between 20-35°C. Terrestrial types do not require very high temperatures during winter dormancy; while keeping the potting soil dry, maintaining a temperature of 4-7°C is sufficient. Epiphytic types, however, require higher temperatures in winter, preferably maintaining 10-13°C or higher. When summer temperatures reach 30-35°C, the growth rate of most cacti slows down, and sometimes the stems of certain species will turn yellow or be scorched; at this time they must be shaded and more water sprinkled on the ground to lower the temperature.
(5) Air
Most cactus flowers are native to open desert areas with good ventilation and fresh air. Therefore, in the hot midsummer weather, ventilation and cooling work at the cultivation site should be done well. Cultivation greenhouses should be chosen in an environment with air circulation, and more ventilation openings such as windows and skylights should be installed so as to ventilate and exchange air in hot weather. If necessary, equipment such as exhaust fans, blowers or electric fans can also be installed to strengthen the air circulation effect of the environment, so as to help cactus flowers safely pass through summer.
(6) Pests and diseases
The pathogens harming cactus flowers include bacteria and fungi, but the problem is not very serious. As long as cultivation conditions are improved, management measures are appropriate, and prevention and elimination of pests and diseases are combined, good results are easily obtained. The more common pests and diseases mainly include:
1. Rot disease. Its pathogens include both bacteria and fungi. The occurrence of this disease is often related to improper watering, poor drainage of the potting soil, and continuous excessive moisture. After discovering diseased plants, immediately use a sharp knife to cut off the diseased tissue, and coat the cut with charcoal powder or sulfur powder; at the same time, reduce watering or change the pot, and take new cuttings or graft again. It is best to regularly spray a 40% copper oxychloride suspension at 800-1000 times dilution at the planting site and on the plants for prevention, but the main thing is still to improve ventilation conditions and avoid continuous excessive moisture.
2. Damage by insects and other animals. Mainly scale insects, red spider mites and slugs, etc. To control scale insects, spray a 50% omethoate emulsion at 1000 times dilution; to control red spider mites, spray a 20% dicofol wettable powder at 600 times dilution or a 40% dicofol emulsifiable concentrate at 1000 times dilution; to control rats and woodlice, spray chlorpyrifos at 2000 times dilution around flower stands and flower pots; to control snails and slugs, sprinkle lime powder around the flower pots, or apply 8% metaldehyde granules; to control cockroaches and ants, place cockroach and ant-killing drugs or mix sugar water with trichlorfon to poison them.
The above is an introduction to the classification, roles and cultivation methods of cactus. For more home plants, please stay tuned.
What is the role of Gerbera daisy? Gerbera daisy cultivation methods
Gerbera daisy: (scientific name: Gerbera jamesonii Bolus) is a perennial herbaceous plant of the family Asteraceae, also known as sun flower, orangutan chrysanthemum, sun-head flower and so on. Propagation is by sowing or division. The plant height is 30-45 cm, the rhizome is short and surrounded by remnant leaf petioles, and most leaves are basal and pinnately lobed. It has relatively thick fibrous roots and terminal inflorescences; the flowers are huge, with colors including red, white, yellow, orange, purple and so on. The flower colors are rich, management is labor-saving, and in warm regions it can be supplied all year round. It is an important material in modern cut flowers, used for flower arrangement and making flower baskets, and can also be grown in pots for ornamental use.
The main types can be divided into modern cut-flower types and dwarf cultivation types. Its place of origin is South Africa, and it was later introduced to the United Kingdom; now it is widely cultivated around the world. It is said that Gerbera daisy can also change the home environment. Below, let us take a look at how Gerbera daisy changes the home environment and its cultivation methods.
Introduction to Gerbera daisy
1. The appearance of Gerbera daisy. Numerous small and pointed petals surround a sun-shaped flower center, and the soft flower center is filled with yellow, red or pink, etc., a very cute appearance. It is a perennial herb of the family Asteraceae, with fine hairs all over the plant, most leaves basal and pinnately lobed, and solitary capitula. The plant height is 30-45 cm, leaves are basal, petioles are long, leaf blades are oblong-spatulate, pinnately lobed or deeply lobed. The capitulum is solitary, rising 20-40 cm above the leaves, the flower diameter is 10-12 cm, the involucre is disk-shaped and bell-shaped, and the ligulate petals are in 1-2 or multiple whorls and double-flowered in form. The flower colors include bright red, orange-red, pale red, yellow and so on. It usually flowers in all four seasons, with the most abundant flowering in spring and autumn.
2. It needs appropriate temperature, humidity and pH. Gerbera daisy is a perennial evergreen herbaceous plant with persistent roots, and there are about 45 species in the same genus. It likes environments that are warm in winter and cool in summer, with air circulation and sufficient sunlight; it is not cold-tolerant and avoids intense heat. It likes fertile, loose, well-drained sandy loam rich in humus, avoids heavy clay soil, and prefers slightly acidic soil; the optimum growth pH is 6.0-7.0. The optimum growth temperature is 20-25°C, and the optimum winter temperature is 12-15°C. It stops growing below 10°C. It is a semi-cold-tolerant flower and can endure short periods of 0°C low temperature.
2. It is a flower full of poetry. Gerbera daisy is also known as f ulang flower, symbolizing mutual respect and mutual love, perseverance, and fearlessness of hardship. In some regions, people like to use f ulang flowers to make bouquets to decorate the bridal room during wedding celebrations. Taking its homophonic meaning, it embodies the meaning of mutual respect and mutual love between newlyweds. The flower shape of Gerbera daisy is radial, often used as the main body of flower arrangements, and is often combined with Boston fern and asparagus fern. At the same time, it also represents mystery, excitement, perseverance, elegance, seclusion and nobility. Its flower language is passion and eternal happiness.
3. It has many varieties and each has its own characteristics. The varieties of Gerbera daisy can be divided into three categories: narrow-petal type, wide-petal type and double-flowered type. Common ones include Marin: yellow double-flowered; Delfi: white wide-petal; Helios: vermilion wide-petal; Carmen: dark rose-red wide-petal; Kitty: rose-red petals with a black center. At present, varieties with black centers are especially loved by people.
4. Its name comes from a legend. In the early 20th century, Madagascar in southern Africa was a small country rich in tropical flowers and plants. There was a local girl named Slangyini who, from childhood, very much liked this kind of wildflower with slightly curved stems and drooping flowers. When she married, she asked for more of them to be arranged in the hall to add to the wedding atmosphere. Relatives and friends from all sides sang and danced and repeatedly toasted each other. Who would have expected that the groom, with very little tolerance for alcohol, became drunk after only three rounds of drinks; he bowed his head and bent his waist, leaning east and west, and the bride had no choice but to support him into the bedroom to rest. Seeing this supporting posture and how similar it was to the growth posture of that wildflower, quite a few girls said in unison: "Oh, the flower really looks like it is supporting the groom!" From then on, the name f ulang flower spread far and wide.
The role of Gerbera daisy in the home environment
1. It can regulate indoor temperature: when the temperature is high, it can lower it, and when the temperature is low, it can raise it. In hot summer, Gerbera daisy performs respiration, taking in carbon dioxide carrying heat from the air and then releasing oxygen. In this process, it absorbs part of the heat, making the overall indoor temperature lower; in winter, whether indoors or outdoors it is very cold, and Gerbera daisy performs respiration, producing heat during the process, driving up the temperature of the whole home and playing a heat-preserving role.
2. Its role in beautifying the home cannot be ignored. Gerbera daisy, also known as sun flower, orangutan chrysanthemum, sun-head flower and so on, is a perennial herbaceous plant with terminal inflorescences, and the flower colors include red, white, yellow, orange, purple and so on. With so many bright and eye-catching colors, if planted together in one home, the home becomes colorful and gorgeous, extremely beautiful. Potted Gerbera daisy is often used to decorate doorways and halls, and its cut flowers are used in vases and flower arrangements to adorn desks, display windows and living rooms. With pink Gerbera daisy as the main flower, paired with dendrobium, baby's breath and orchid leaves, the tone is elegant and the interest is strong. If red Gerbera daisy is used as the main flower, paired with Boston fern, palm bamboo leaves, dried branches and dyed walnuts for wall-hanging decoration, it can produce a relatively strong decorative effect.
3. Gerbera daisy can indicate whether light and ventilation conditions are good. Human living environments and plant growth needs have a certain degree of similarity. Gerbera daisy is a light-loving plant, and a location with sufficient light should be chosen for cultivation. Seedlings should not be planted too deep, and the root buds need to be exposed above the soil surface. If light is insufficient, the flower stalks become soft and droop, and the quality of cut flowers is not high. The color of Gerbera daisy in midsummer, especially under drought and water shortage, becomes dark and dull; while flowers blooming during the suitable-temperature period of September to October or March to June of the following year have bright colors. This shows that Gerbera daisy is relatively sensitive to temperature and light intensity. In summer, the soil must be kept moist and not allowed to suffer drought, a shade net with 50% light transmittance should be used for covering, and water should be sprayed on the leaves to increase air humidity and lower the temperature; in winter, warmth preservation work should be done well and the plant should not be frozen, with the nighttime temperature not lower than 10°C and the daytime temperature not lower than 15°C. These are all very beneficial for improving the brightness of Gerbera daisy. In addition, mites are a major enemy in Gerbera daisy cultivation; once damaged, not only does it lose its brightness, but the shape of the petals also becomes incomplete. Observing the growth of Gerbera daisy can always bring us certain help in life.
The feng shui role of Gerbera daisy
1. Gerbera daisy can promote a woman's romance. The bedroom is probably the most important space for changing a woman, especially when in love, most random thoughts occur in the bedroom. Love feng shui requires confirming the bedroom arrangement; for example, placing a fresh and long-lasting Gerbera daisy at the bedside, with a fragrance that is somewhat pleasant and will not easily disappear, can encourage oneself.
2. Gerbera daisy can promote family harmony. Like sunflowers, Gerbera daisy is a flower that represents the sun in everyone's mind, except that the latter is tall and mighty, while the former is elegant and upright. If the sunflower is the blazing sun shining high in summer, then Gerbera daisy is like the warm sun in winter, making people feel cozy. Someone once advocated using Gerbera daisy as the flower representing Father's Day, because Gerbera daisy is also called sun flower, and the sun can also symbolize fatherly love. The feng shui role of Gerbera daisy can keep a family living in harmony and loving each other, and this is where the saying comes from.
3. For people whose Five Elements belong to fire, Gerbera daisy is their lucky flower. In Chinese feng shui, it is believed that the types, attributes and placement positions of some plants can affect a person's fate. Plants also have yin-yang and Five Elements distinctions; using them appropriately in different directions and environments can produce even more unexpected regulating effects. In geomancy it is believed that plants are spiritual and can help people in various aspects to a certain extent, so plants are often used to regulate environmental energy fields. There are many types of plants and their properties differ greatly, so there are also many particular points when using them; such plants are called feng shui plants. People whose Five Elements belong to fire should choose red as the main color, because red is the original color of fire, or choose the original color of wood, green, as the main color, because green wood generates and strengthens red fire. From a feng shui perspective, this can bring prosperous good luck to the homeowner and their family. Of course, besides red, Gerbera daisy also has many other colors, so Gerbera daisy is a lucky star for many people; as the color of Gerbera daisy changes, the group of people it blesses is different.
The role of Gerbera daisy
1. Gerbera daisy is a beautiful plant, and the effect of using it for home decoration is quite good. Potted Gerbera daisy is often used to decorate doorways and halls, and its cut flowers are used in vases and flower arrangements to adorn desks, display windows and living rooms. With pink Gerbera daisy as the main flower, paired with dendrobium, baby's breath and orchid leaves, the tone is elegant and the interest is strong. If red Gerbera daisy is used as the main flower, paired with Boston fern, palm bamboo leaves, dried branches and dyed walnuts for wall-hanging decoration, it can produce a relatively strong decorative effect. At the same time, Gerbera daisy is also known as f ulang flower, native to southern Africa. Its flowers are large and beautiful, and its delicate posture is pleasing to the eye; it is an important cut-flower decorative material. Large red Gerbera daisies are used for bridal bouquets. Together with roses, gladiolus and carnations, it is listed as one of the world's best-selling "four major cut flowers."
2. Gerbera daisy can measure whether the indoor environment is good or bad. Gerbera daisy is a light-loving plant, and a location with sufficient light should be chosen for cultivation. Seedlings should not be planted too deep, and the root buds need to be exposed above the soil surface. If light is insufficient, the flower stalks become soft and droop, and the quality of cut flowers is not high. From the growth of Gerbera daisy, one can judge whether the light is sufficient.
The color of Gerbera daisy in midsummer, especially under drought and water shortage, becomes dark and dull; while flowers blooming during the suitable-temperature period of September to October or March to June of the following year have bright colors. This shows that Gerbera daisy is relatively sensitive to temperature and light intensity. In summer, the soil must be kept moist and not allowed to suffer drought, a shade net with 50% light transmittance should be used for covering, and water should be sprayed on the leaves to increase air humidity and lower the temperature; in winter, warmth preservation work should be done well and the plant should not be frozen, with the nighttime temperature not lower than 10°C and the daytime temperature not lower than 15°C. These are all very beneficial for improving the brightness of Gerbera daisy. In addition, mites are a major enemy in Gerbera daisy cultivation; once damaged, not only does it lose its brightness, but the shape of the petals also becomes incomplete. The cause of root rot in Gerbera daisy is mostly root rot disease occurring in the roots, and once it occurs it is difficult to cure completely. The external conditions that produce root rot disease are excessive moisture in the root soil, long-term water accumulation in the root zone, or long-term rainfall in open field cultivation, which can cause the death of Gerbera daisy plants. From the growth of Gerbera daisy, one can see whether its roots are growing healthily, and from the judgment of the roots one can infer the home environment.
3. Gerbera daisy also has quite a few roles in greening the home. Gerbera daisy is a perennial herb. Leaves are pinnately deeply lobed. Flowers are solitary, capitula, and the flower stalks rise above the leaf cluster. Common varieties include the red "Passion," the yellow "Sun Dance," the white "Bianca" and so on. Miniature small-flowered types include "Ballroom" (white), "Ballet" (orange), "Sudan" (yellow), "Kanga" (red) and so on. Planting one or two pots at home allows you to feel the breath of nature and also enjoy the fresh air released by Gerbera daisy every day.
The role of Gerbera daisy in matching home styles
1. The flower language of Gerbera daisy has the role of encouraging and blessing the owner's life. Gerbera daisy is also known as f ulang flower, symbolizing mutual respect and mutual love, perseverance, and fearlessness of hardship. In some regions, people like to use f ulang flowers to make bouquets to decorate the bridal room during wedding celebrations. Taking its homophonic meaning, it embodies the meaning of mutual respect and mutual love between newlyweds. The flower shape of Gerbera daisy is radial, often used as the main body of flower arrangements, and is often combined with Boston fern and asparagus fern. At the same time, it also represents mystery, excitement, perseverance, elegance, seclusion and nobility. Its flower language is passion and eternal happiness. Its flower language all shows that Gerbera daisy is a plant that loves life; while living strongly itself, it also encourages everyone to love life.
2. Placed next to a television or computer, it embodies a home style that yearns for health and loves nature. In a home, apart from the microwave oven, the place with the greatest radiation is in front of the television and computer screens. When we look at computers and televisions for a long time, our eyes feel very tired. At this time, looking at the Gerbera daisy placed nearby is a kind of adjustment; the bright and natural colors make us feel comfortable and released. Moreover, before radiation enters our eyes and skin and affects our brain's thinking, Gerbera daisy has already absorbed part of the radiation and removed part of the harm. A healthy home life is created at this moment.
3. Placed in the living room, Gerbera daisy can match a noble home style. Flowers blooming bring wealth and fully display luxury; this is the European style. The European style pursues an elegant sense of luxury, and this kind of gorgeous space is very suitable for being set off by the many-flowered Gerbera daisy. Compared with plants of Chinese style temperament, which focus on foliage, the European style focuses more on flower pots, and indoor flowers are also mainly water-grown cut flowers. Close your eyes; do you smell the rose atmosphere beneath an English castle?
Gerbera daisy comes from Africa, but it can not only present an African home style; it can also be paired with many different home styles, and the more it is paired, the more wonderful it becomes.
Gerbera daisy cultivation methods
The diseases of Gerbera daisy are a little different from those of ordinary flowers; let us learn about them together!
1. When caring for Gerbera daisy, special attention should be paid to the diseases that may occur on it.
1. Phytophthora blight: The key to prevention and control is that continuous cropping soil must be disinfected with Weibomu and formaldehyde, etc.; see the instructions for usage and dosage. Plant shallowly, with the root crown exposed 1 cm above the surface; prevent the soil from being too wet. If soil below 10 cm of topsoil does not form a ball after being placed in the palm and squeezed hard, then it can be watered. In the early stage of disease, when part of the leaf turns red and wilting begins, drench the roots with 58% phosethyl-Al and mancozeb at 400 times dilution, then 7 days later drench the roots with 64% oxadixyl and folpet powder at 500 times dilution. Apply the pesticide in the early morning or evening when the temperature is low, and stop applying when the temperature is above 28 degrees. Use the pesticide once every 7 days, for 3 consecutive times.
2. Powdery mildew: The key to prevention and control is to keep the greenhouse ventilated and low in humidity; promptly remove diseased leaves; when disease occurs, spray 70% thiophanate-methyl at 1500 times dilution, or use 20% fungicide smoke for fumigation control, once every 7 days, for 2-3 consecutive treatments. In addition, use the sulfur fumigation method for prevention and control: put 20-30 g of sulfur powder into each fumigator, and after lowering the curtain at 17:00 each day, keep the greenhouse sealed and energize and heat for 2 hours, replacing the sulfur powder once every 6 days, and continuing fumigation for 15 days. During the outbreak period of powdery mildew, fumigate 8-10 h every day, and powdery mildew can be eliminated in about 10 days.
3. Leaf spot disease: The key to prevention and control is to promptly remove diseased leaves when found and destroy them centrally; in the early stage of disease, spray 2.5% myclobutanil emulsifiable concentrate at 300 times dilution or 70% thiophanate-methyl wettable powder at 800-**** times dilution, once every 7 days, for 2-3 consecutive sprays.
4. Gray mold: The key to prevention and control is that controlling humidity is the key to preventing and treating gray mold. Thin out densely planted and overly dense leaves; increase ventilation and air permeability, and keep air humidity at 75-85%; water from below the plant crown; to prevent water vapor from condensing on the flowers, after 10 a.m. on sunny days, gradually open the side greenhouse covering, avoiding a sharp rise in temperature inside the greenhouse; in the early stage of disease, spray the leaves with 70% thiophanate-methyl at 1500 times dilution, and combine with smoke agents for prevention and control.
5. Whitefly: The key to prevention and control is to thoroughly remove weeds; insert yellow sticky boards for monitoring at any time, and once insect damage is found, take measures promptly; choose good pesticides and use them correctly: whitefly easily develops resistance to pesticides, so pesticides must be rotated. Pesticides with better effects include beta-cypermethrin, abamectin, imidacloprid and so on. Choose dawn for spraying, seal the greenhouse for 4-5 hours after spraying, and spray once continuously the next morning.
2. Temperature requirements. Use cultivation facilities to satisfy as much as possible the temperature requirements of Gerbera daisy during the seedling stage, growth period and flowering period, so as to facilitate normal growth and flowering. Outside South China, it cannot overwinter in the open field and requires greenhouse cultivation; outside the Yangtze River basin, it can be cultivated in unheated plastic tunnels. In summer, shade nets need to be covered on top of the tunnel, and the plastic film on both sides of the tunnel should be opened to lower the temperature. In winter, when the outdoor nighttime temperature approaches 0°C, seal the plastic film tightly, and plastic film must be added inside the tunnel for covering. On clear and warm days, open the film at the south end of the tunnel around noon for ventilation for about one hour.
3. Light requirements. Gerbera daisy is a light-loving flower; in winter it needs full light, but in summer attention should be paid to appropriate shading and strengthening ventilation to lower the temperature and prevent high temperature from causing dormancy.
4. Irrigation requirements. After planting, during the seedling stage, keep appropriately moist and control seedlings to promote root development and rapid establishment. During vigorous growth, sufficient water supply should be maintained; in summer, water once every 3-4 days, and in winter about once every half month. When watering during the flowering period, be careful not to let water touch the center of the leaf cluster, to prevent flower buds from rotting. In open field cultivation, attention should be paid to preventing waterlogging. In addition, watering can be combined with fertilizing.
5. Topdressing requirements. Gerbera daisy is a fertilizer-loving perennial root flower with a high demand for fertilizer; the ratio of nitrogen, phosphorus and potassium in fertilization is 15:18:25. When topdressing, special attention should be paid to supplementing potassium fertilizer. Generally, apply 2.5 kg of potassium sulfate per mu, and 1.2 kg of ammonium nitrate or ammonium phosphate; in spring and autumn, once every 5-6 days, and in winter and summer, once every 10 days. If high temperature or relatively low temperature causes the plant to enter a semi-dormant state, then stop fertilizing.
