How to grow Lilium lancifolium? Detailed explanation of high-yield cultivation techniques
How to grow Lilium lancifolium? How to grow Lilium lancifolium with high yield? This is a question every Lilium lancifolium grower needs to consider. Today, the editor will talk about how to grow Lilium lancifolium with high yield and high efficiency. Please read on.
I. Loosening soil and supplementing fertilizer
When planting lilies, it is necessary to do a good job of intertillage and soil loosening, loosening soil and supplementing fertilizer, and preserving soil moisture and storing water. When the lily seedlings grow to 10 cm, intertillage and soil loosening should be carried out. In the second and third years, appropriate deep intertillage can be done. After the third year, soil loosening should be shallow rather than deep, otherwise it is easy to damage the root system and bulbs. After loosening the soil, timely topdressing of seedling-promoting fertilizer should be applied, with 15-20 kg of 45% nitrogen-phosphorus-potassium compound fertilizer applied per mu.
II. Plant adjustment
1. Topping and pinching
Topping and pinching the top of the lily can reduce the consumption of nutrients by the growth of aboveground stems and leaves, thereby promoting the growth and development of the bulb. In early June, when the lily seedlings grow to 40 cm, topping and pinching can be carried out. It should be noted that pinching should be done around noon on sunny days, which is beneficial for wound healing.
2. Removing flower buds
Removing flower buds can not only reduce nutrient consumption, but also reduce adverse effects on bulb development. When removing flower buds, pinch off the buds when the flower stem grows to 1-3 cm. It should be noted that the time for pinching off flower buds cannot be too early or too late. If too early, the plant will be damaged; if too late, the flower stem tissue will age and be difficult to break off. Because lilies bud at different times, growers need to inspect every day and remove them repeatedly.
3. Removing bulbils
Multiple bulbils grow in the leaf axils of lilies. For those not using bulbils to propagate seed bulbs, they can be removed when the bulbils are just beginning to swell and have not yet changed color. This can both make full use of nutrients and promote bulb enlargement. It should be noted that bud removal should be carried out on sunny days to prevent breaking the plant and damaging functional leaves.
III. Shading and cooling
The optimal growth temperature for lilies is 15-25 degrees. If the temperature is 28 degrees, it will hinder lily growth. If the temperature is higher than 33 degrees, it will cause the plant to wither and die. Therefore, interplanting corn can be adopted to shade and cool through the corn plants.
IV. Fertilizer and water management
1. Late growth stage
Control the application amount of nitrogen fertilizer, because after topping, if too much nitrogen fertilizer is applied, the stems and leaves will grow excessively, affecting bulb enlargement. Therefore, 30 kg of compound fertilizer containing 15% each of nitrogen, phosphorus, and potassium should be applied per mu. In July, 0.2% potassium dihydrogen phosphate can be sprayed on the leaves, or plant biostimulant can be sprayed to prevent premature leaf senescence.
2. Bulb enlargement stage
Because the lily bulb enlargement stage coincides with the rainy season, drainage measures should be well done to prevent waterlogging.
V. Chemical weed control
1. Pre-emergence weed control
Pre-emergence weed control mainly targets grassy and broadleaf weeds. It can be controlled with 48% trifluralin emulsifiable concentrate or 33% pendimethalin emulsifiable concentrate at 2500 mL per hectare, or with 48% butralin emulsifiable concentrate at 3750 mL per hectare.
2. Post-emergence weed control
When lily seedlings grow to 20-30 cm, 2000 mL of 10% quizalofop-p-ethyl emulsifiable concentrate per hectare, or 750 mL of 24% oxyfluorfen, can be used for spray control.
VI. Control of diseases, insect pests, and rodents
1. Damping-off
After emergence, spray 50% carbendazim 1000-fold solution once every 10-15 days, for 2-3 consecutive sprays. After disease onset, diseased plants should be pulled out in time. For diseased areas, 50% lime milk can be used for disinfection.
2. Leaf blight
It can be controlled by spraying 50% carbendazim 500-fold solution, or 75% chlorothalonil 500-fold solution, or 70% thiophanate-methyl 500-fold solution, or 50% procymidone 1000-fold solution, once every 10-15 days, for 2-3 consecutive sprays.
3. Lily blight
Spray 0.5% Bordeaux mixture 1000-fold solution, or 25% metalaxyl 2000-fold solution, or 70% dexon original powder 1000-fold solution. When spraying, it should be soaked through.
4. Aphids
Spray with 40% dimethoate 1200-fold solution, or 10% imidacloprid wettable powder 2000-3000-fold solution, or 3% acetamiprid emulsifiable concentrate 2000-2500-fold solution.
5. White grubs
50% malathion 800-1000-fold solution or 50% phoxim emulsifiable concentrate 1000-fold solution can be used to drench the soil.
6. Rodent damage
When the soil thaws in spring, poison bait should be placed, using 1 kg of 0.005% bromadiolone bait per mu, scattered on the land surface. Of course, if a small-dose, multiple-application method is adopted, the control effect is even better.
Can Lilium lancifolium be grown in Lishui? High-quality and high-yield cultivation techniques for Lilium lancifolium in the Lishui area
Lilium lancifolium is a medicinal plant with high ornamental value and is also often called Juan Dan. Below, the editor will tell you about high-quality and high-yield cultivation techniques for Lilium lancifolium in the Lishui area.
Lishui City is located in the mountainous area of southwestern Zhejiang Province, with nine parts mountains, half a part water, and half a part farmland. The terrain is mainly mid-mountain and hilly landforms, with obvious vertical climate differences. The land area above 500 m elevation is 14,000 hm2. Because these lands are shaded by trees around them, with streams passing through the middle, cool summers, large day-night temperature differences, and high soil organic matter content, they are conducive to the accumulation of crop organic matter and have a low incidence of pests and diseases. In order to fully leverage the rich geographical resource advantages and diverse climate conditions of the Lishui mountainous area, increase the economic income of mountain farmers, and accelerate the pace of mountain farmers escaping poverty and becoming prosperous, lilies were introduced for trial planting. From them, Lilium lancifolium varieties with good yield, strong disease resistance, good marketability, high nutritional and medicinal value, broad market prospects, and suitability for cultivation in the Lishui mountainous area were selected. After trial planting and promotion in recent years, the city's planting area has now reached 378.7 hm2, with yield reaching 22.5 t/hm2 and economic benefits of 120,000-150,000 yuan/hm2. They are mainly distributed in Qingtian, Suichang, Jingning, Songxian, and other counties. The high-yield cultivation techniques for Lilium lancifolium in mountainous areas are summarized as follows.
1. Plot selection
Lilium lancifolium likes drought, fears waterlogging, prefers cool shade, and is very cold-resistant. High-temperature areas will affect its growth. It grows vigorously, has large bulbs, and high yield. When planting, sandy loam or loam with elevation above 500 m, fertile soil, high and dry terrain, good drainage, and loose texture should be selected for cultivation; the natural conditions of sparse forest and half shade and half sun in mountainous areas should be used. Lilies are unsuitable for continuous cropping. It is advisable to choose plots where the previous crop was not lilies, Atractylodes macrocephala, potatoes, or other root and tuber crops. The previous crop is best beans, melons, or vegetables. After harvest that year, it is more suitable to plant rice, wild rice stem, and other crops the following year for paddy-upland rotation cultivation.
2. Land preparation and basal fertilizer application
2.1 Land preparation and bed making
5-10 d before planting, clear the residues of the previous crop and weeds in the field, then plow 30-35 cm and harrow finely and level. Generally, the bed surface width is 80-100 cm, the bed height is 20-30 cm, made into a turtle-back shape, and the ditch width is 30 cm, which is conducive to drainage, ventilation, and weed control and other farming operations. At the same time, during plowing, spread quicklime at 900-1,200 kg/hm2 for soil disinfection.
2.2 Applying sufficient basal fertilizer
The whole growth period of lily exceeds 250 d, and the fertilizer requirement is large. The basal fertilizer should mainly be long-acting, high-quality, decomposed organic fertilizer [2]. Apply decomposed organic fertilizer at 18.0-22.5 t/hm2 or cake fertilizer at 2,250 kg/hm2 (the cake fertilizer uses tea seed cake, which can kill eggs of underground pests such as cutworms), calcium superphosphate at 375 kg/hm2, and ammonium bicarbonate at 750 kg/hm2. Apply in furrows, then cover with soil to prevent nutrient volatilization and loss. The soil in the Lishui mountainous area is generally deficient in potassium, with a pH value of about 5, slightly acidic, so appropriate additional application of potassium sulfate or plant ash is needed. Generally, add potassium sulfate at 150 kg/hm2 or plant ash at 1,500 kg/hm2. Quicklime at 3,750 kg/hm2 can also be used for disinfection and acid adjustment.
3. Sowing at the appropriate time
3.1 Seed selection
Select lily bulbs with a single head weight of 30-40 g and 3-4 heads as seed bulbs. The seed bulbs are required to be flat-headed, spotless, undamaged, and with scales tightly clasped without splitting. The seed bulb dosage is 3,750-4,500 kg/hm2.
3.2 Disinfection
Before sowing, soak the seed bulbs in 800-1,200-fold solution of carbendazim wettable powder, thiophanate-methyl, or other fungicides for 15-30 min for disinfection, then remove them and place them in a cool place to dry.
3.3 Selection of sowing time
Lilium lancifolium is sown from early October to mid-November. Generally, high mountain areas above 500 m elevation are suitable for sowing in early to mid-October, while areas below 500 m elevation are suitable for sowing in mid-to-late October. The specific time is adjusted according to different elevations. As elevation increases, the sowing period should be correspondingly earlier.
3.4 Sowing
The soil should remain moist during sowing. The sowing density is 30-35 cm row spacing and 15-20 cm plant spacing. Open furrows, place the seed bulbs with the top facing upward, and sow at a depth of 10-15 cm, then cover with 4-6 cm of soil. In dry weather, shade nets or weeds can be used for mulching, which is beneficial for moisture retention and emergence. After emergence, remove the shade net.
4. Field management
4.1 Straw mulching
Before lily emergence, attention should be paid to moisture retention, heat preservation, and weed prevention. In mid-to-late November, the weather gradually turns cooler and the temperature drops, so rice straw, bean stalks, corn stalks, and other mulching materials should be used for heat preservation, moisture retention, weed prevention, prevention of heavy rain erosion, and prevention of surface soil crusting. The Lishui mountainous area promotes straw return, and there are many available mulching materials. Mulching is conducive to early emergence and good seedling emergence.
4.2 Fertilization
After emergence, apply seedling fertilizer steadily, generally in early to mid-January. Because January weather is relatively cold and the temperature is relatively low, organic fertilizer should be the main component, with an appropriate amount of compound fertilizer added. Generally, apply decomposed organic fertilizer at 7,500-12,000 kg/hm2, evenly spread on the bed surface, to provide heat preservation and frost prevention, and apply compound fertilizer at 150 kg/hm2 as seedling-promoting fertilizer. From sowing to emergence, lilies generally take about 100 d in the Lishui mountainous area. After emergence, generally in mid-March, when lily seedlings are 10-20 cm tall, apply decomposed cake fertilizer at 1,500 kg/hm2 and compound fertilizer at 150 kg/hm2 as seedling-promoting fertilizer to promote strong seedlings. Apply topping fertilizer appropriately. In mid-to-late May, after topping, apply urea at 150 kg/hm2 and potassium sulfate at 150 kg/hm2 to promote scale enlargement. At the same time, use 0.2% potassium dihydrogen phosphate solution for foliar fertilization. This topdressing should be completed 45-55 d before harvest.
4.3 Earthing up
Combine intertillage and weeding with shallow earthing up. The earthing up should not be too thick, and it is appropriate that the bulbs do not expose above the soil surface. After lily growth closes the rows, intertillage and weeding can be stopped. However, ditches should be cleared in time to ensure smooth water flow, so as to avoid waterlogging affecting plant growth and development.
4.4 Bud removal
In mid-to-late May, when buds appear, choose noon on sunny days and top and remove buds in time according to plant growth. Plants with vigorous growth should be topped heavily, while weak plants should be topped later, and flower buds should be removed. Generally, top about 5 cm. Topping is an important technical step for high yield of Lilium lancifolium. The yield difference between topping and not topping is 15%-20%.
4.5 Water management
Lilies fear waterlogging. In the rainy spring season and after heavy rain, ditches should be dredged and drained in time, keeping ditches unobstructed and clearing them in time so that water dries after rain stops. In summer, prevent rot caused by high temperatures; during continuous drought, irrigate with shallow flooding; after the soil is moistened, drain in time. From July to August, the bulbs enlarge and enter summer dormancy, so the soil should be kept dry and loose, and waterlogging must be strictly avoided.
5. Control of diseases, insects, and weeds
In mountainous areas, the occurrence of pests and diseases is relatively light. During the growth and development of lilies, the more common pests and diseases mainly include blight, viral disease, gray mold, aphids, seed maggots, and others.
For blight control, agricultural control measures focusing on prevention should be adopted, paddy-upland rotation should be implemented, and plots with good drainage and loose soil should be selected for cultivation, or deep furrows and high beds should be used for cultivation to facilitate drainage. In the early stage of disease, spray 40% aluminum triethyl phosphonate wettable powder 250-fold solution, or 58% metalaxyl mancozeb wettable powder (or 64% sandofan wettable powder) 500-fold solution, or 72% DuPont Curzate wettable powder 800-fold solution. After disease onset, pull out diseased plants in time, burn them in a centralized manner or bury them deeply, and treat the area around the diseased area with 50% lime milk.
For viral disease control, strengthen field management, appropriately increase phosphorus and potassium fertilizer, make plants grow robustly, and enhance disease resistance; during the growing period, spray 10% imidacloprid wettable powder 1,500-fold solution or 50% pirimicarb ultra-fine wettable powder 2,000-fold solution in time to control virus-transmitting aphids and reduce the spread of pests and diseases. In the early stage of disease, spray 20% Dukexing wettable powder 500-600-fold solution or 0.5% antiviral agent No. 1 aqueous solution 500-fold solution, once every 7-10 d, for 3 consecutive sprays.
For gray mold control, select healthy disease-free bulbs for propagation. Fields or greenhouses should be ventilated and light-transmitting, avoid overly dense planting, promote robust plants, and increase disease resistance. In winter or after harvest, clear diseased and residual plants in time and burn them, remove diseased leaves in time, and remove diseased flowers to reduce inoculum sources. In the early stage of disease, begin spraying 30% basic copper sulfate suspension 400-fold solution, or 36% thiophanate-methyl suspension 500-fold solution, or 50% iprodione wettable powder 1,000-1,500-fold solution. To prevent drug resistance, rational rotation and alternating use should be advocated. Stop application 3 d before harvest.
For aphid control, clean the field garden, remove weeds in the field, and reduce overwintering insect populations. During occurrence, spray 10% imidacloprid wettable powder 1,500-fold solution, or 50% pirimicarb ultra-fine wettable powder 2,000-fold solution. Scarab larvae can be controlled with malathion or phoxim. Mites can be controlled with acaricides. For seed maggot control, first, disinfect the soil; second, drench the roots with 90% trichlorfon 800-fold solution, which also controls underground pests such as cutworms.
For cutworm control, drench the roots with 90% trichlorfon 800-fold solution, which also controls white grubs, mole crickets, and other underground pests. After lily harvest, flood the entire field to drown them or force them to leave.
For uncovered field plots, carry out intertillage once together with seedling fertilizer application, and use manual weeding. If already covered, generally no further weeding is needed.
6. Harvest
In the autumn of the following year after planting, begin harvest after the aboveground parts have completely withered and the underground parts have fully matured. Harvesting at this time not only gives high yield but also stores well. Lilies generally begin harvest in late July. Fresh vegetable lilies are harvested in batches according to market conditions. Medicinal lilies are harvested once on sunny days. After the bulbs are dug out, cut off the aboveground parts, fibrous roots, and seed roots, then immediately move them indoors to a ventilated place for storage, so as to avoid sunlight causing scale drying and discoloration.
7. Processing
Lilium lancifolium is a lily variety used both for fresh eating and medicine. In order to increase economic income, when fresh-eating sales are weak, drying processing can be carried out. During processing, wash the harvested fresh lilies clean, then separate the scales. When peeling, the outer scales, middle scales, and inner scales should be separated separately, so as to avoid uneven old and tender scales during blanching, making blanching time difficult to control and affecting quality. During blanching, after the water boils, put the scales into the pot and stir promptly. After 5-10 min, when the edges of the scales are soft and the backs have slight cracks, remove them quickly, put them into cold water to cool, and rinse to remove mucus. Then scoop them out and immediately dry them with a dryer. During drying, the temperature should be controlled between 60-70 degrees C, and the drying time is generally about 12 h. When the moisture content is below 12%, take them out and spread them to cool to room temperature, then grade, package, and store.

New techniques for growing lilies
Lily is also known as lily garlic, night-closing flower, Chongmai, and Zhongting. It is a plant of the Liliaceae family, mainly produced in Hunan, Zhejiang, Jiangsu, and other provinces. Lily flowers are elegant in shape and pleasant in fragrance, with great ornamental value. Lilies also contain a variety of alkaloids, starch, protein, fat, and vitamin B1, B2, C, and carotene, etc. They are quite rich in nutrition and are therefore also treated as a delicacy on the table. Lily is sweet with a slight bitterness and neutral in nature. It can moisten the lungs and stop cough, clear the heart and calm the mind, and has special medical and health care effects. Lily fresh cut flowersLilies can be propagated by cuttings, bulb division, and tissue culture. Here we mainly introduce bulb division propagation using lily bulbs, that is, bulbs. The shape of the bulb is similar to a garlic head. It is the underground part of the lily, formed by many scales clasped together. It is said that the name lily comes from this.
The bulb is commonly called a bulb root, but it is not a true root. It is the enlarged and transformed base of the stem. The fibrous structures under the bulb are the roots of the lily. The bulb has a great influence on the growth and development of the lily. Its size is closely related to the number of lily flower buds. Generally, the larger the bulb, the more flowers. During the growth of the lily, some small bulbs will grow at the base of the bulb. Bulb division propagation is the cultivation of these small bulbs into large bulbs with a diameter of more than 12 cm for lily fresh cut flower production. When planting bulbs, first make beds. The bed width is generally 0.8-1.0 m. Measure with bamboo poles and line, then step out a bed length of about 20 cm. After padding the bed surface, deeply plow the soil, because loose soil is beneficial to the growth of lily bulbs. Then level the land and use a rake to draw 6 narrow furrows on the bed surface. The small bulbs are planted in the 6 furrows. Place the bulbs well, note that the roots face downward. The planting distance depends on bulb size, generally 8-10 cm, exactly the distance of a fist. Then sprinkle some compound fertilizer and spray pesticide to disinfect and prevent underground pest damage. In order to facilitate drainage in the rainy season, high-bed cultivation can be adopted. Raise the bed surface and thicken the soil layer, that is, dig up the soil on both sides of the bed surface and cover it on the bed surface, forming a soil layer 8-10 cm thick.
As the spring temperature gradually rises, by mid-to-late April, the young seedlings emerge. This is also the season for weed growth, so weeds should be removed in time. Weeding also plays a role in loosening the soil. Because lilies like a cool and humid environment, humidity is the key to lily planting. The soil should be kept moist for a long time, water should be applied frequently, and water should be sprayed fully and thoroughly. After about 2 months, flower buds appear on the aboveground stems of the lilies. At this time, the flower buds should be removed early to avoid consuming nutrients when flowering, which is not conducive to the growth and enlargement of the bulb.
Bud removal work should be meticulous, taking care not to damage other parts of the plant. After bud removal, spray a fungicide once to prevent wound infection. After September, lily leaves become soft and yellow and stop growing. At this time, the bulbs can be dug. Remove the stems and leaves on the ground, dig out the bulbs together with the roots, and take care to damage the bulbs as little as possible during digging. Depending on the variety, the lily growth period also varies. Early-maturing ones should be harvested early. After harvest, they should be boxed.
First lay plastic sheeting in the basket, spread disinfected sawdust around the bulbs, and keep the sawdust at a certain humidity to maintain the moisture of the bulbs, then cover with plastic sheeting. From October each year to April-May of the following year, there is a large demand for lily fresh cut flowers and prices are relatively high. But this is exactly the dormant period in the natural growth process of lilies, when they cannot bloom. Therefore, artificial control is needed to break the dormant period so that lilies can bloom at the scheduled time.
The specific method is to put the boxed bulbs into a cold storage for low-temperature treatment. Within one month, gradually lower the temperature to the suitable storage temperature of 2-4 degrees C. This is an effective way to break the dormancy of lilies. Storage should be sealed. At intervals, check the cold storage condition once. It is most suitable when the sawdust feels like it has ice crystals when held in the hand. Then, according to the required flowering time, take the bulbs out of the cold storage 3-4 months in advance for planting, so that the lilies bloom on the scheduled date.
Taking fresh cut lily flowers marketed for the Spring Festival as an example, take the bulbs out of the cold storage in September, cultivate them in a greenhouse after thawing, and the planting management measures are basically the same as the method for planting small bulbs. The soil should remain moist. The minimum temperature in the greenhouse cannot be lower than 10 degrees C, the day-night temperature difference cannot exceed 12 degrees, and the relative humidity is 80%-85%. After 2 months, flower buds will grow on the lily plants. Lily fresh cut flowers must be harvested in time. When the first petal on the flower bud shows color, the flowering branch can be cut. The cutting position should be several centimeters above the ground, so that the aboveground stems can continue photosynthesis and accumulate nutrients, allowing the underground bulbs to continue producing small bulbs for use in the next bulb division propagation. In this way, a cyclic cultivation of lily fresh cut flowers is formed.
After harvest, fresh cut flowers should be sorted and packaged. First remove the leaves below 10 cm on the lower part of the stems, tie them with string, wrap them in plastic paper, and one by one lily flower bunches in bud are ready. In order to maintain the freshness of the flowers, the bunches can be placed in a bucket so that water submerges the bottom of the stems. In this way, lily fresh cut flowers can be supplied to the market.
Lilium lancifolium
In the past two years, there has been an additional food on dining tables in Suzhou, Shanghai, and other cities. It looks like petals, tastes like fruit flesh, and is actually the bulb of a vegetable, namely Lilium lancifolium. People make it into lily rolls, cuttlefish lily, loofah lily, sesame lily, and lily mung bean almond porridge. They have eaten it in many ways and also eaten health and beauty. The market for this lily is growing. It stands to reason that as life gets better and better, people's tastes also become more picky. How did this slightly bitter Lilium lancifolium become a new dietary fashion for urban people?
With the improvement of living standards, people increasingly value nutritional balance. Lilium lancifolium is one of the medicinal lilies included in the Chinese pharmacopoeia. It has the effects of moistening the lungs and stopping cough, clearing heat and detoxifying, and calming the mind and benefiting qi. Therefore, it has not only become a delicacy on the table, but also a daily tonic for urban people.
Lilium lancifolium is not an ornamental flower and is mainly cultivated as a vegetable. Its bulb color is yellowish, somewhat like the color of tiger skin, so it is also called tiger lily. Lilium lancifolium is planted from August to September each year and harvested in June of the following year. August each year is the peak sales season for lilies, and transactions in fields, houses, and courtyards also become brisk. During the more than 40-day peak sales season, 250 tons of lilies are shipped from Chajian Town every day to wholesale markets and supermarkets in large cities such as Shanghai, Suzhou, and Hangzhou. This shows how much people in Jiangnan love lilies. Just think, if northerners also developed the habit of eating lilies, how big the lily market would be. Knowing that lilies have such a large market, you must want to know what kind of soil and climate are suitable for growing Lilium lancifolium.
Lilies are cold-resistant, fertilizer-resistant, and drought-resistant. Fertilizer-resistant means they have relatively high demand for nitrogen, phosphorus, and potassium content in the soil; cold-resistant means they can safely pass through the overwintering dormant period at around minus 10 degrees; lilies are also relatively drought-resistant, and excessive humidity is extremely harmful to their growth. When growing lilies in the north, in order to increase yield, it is best to choose sandy soil. Because sandy soil has deep soil layers, good aeration, and high oxygen content.
Once lilies are grown well, ways must still be found to grow them for the long term and make them valuable. How can the value of lilies be raised and multiplied? Process lilies and produce a series of lily products, such as canned lilies, lily powder, lily extract, lily beverages, etc., and then sell them to supermarkets. Calculated this way, the development prospects for lilies are quite considerable.
If every person across the country ate lilies, lily sales would increase even more with people's acceptance.”
Edible large lilies
Edible lilies have a history of several thousand years in China. According to the Compendium of Materia Medica, lilies have the effect of calming the heart and stabilizing courage. The bulbs are rich in protein, starch, fat, alkaloids, and various other components, with very high nutritional value. They can clear heat and detoxify, moisten the lungs and stop cough, replenish qi, reduce swelling and resist cancer, and beautify. Therefore, they have always been regarded as a good tonic food. They can be steamed, boiled in soup, as well as stir-fried, deep-fried, braised, and stewed. There are more than 100 varieties listed in recipe books alone. Because lilies are treasures from head to toe, markets in the United States, Southeast Asia, and elsewhere have gradually recognized their value and come to China to import lilies.
Lilies belong to the genus Lilium in the Liliaceae family. There are about more than 100 species worldwide, and our country has 39 species, mainly distributed in 4 production areas: Yixing in Jiangsu, Luoyang in Henan, Longya in Hunan, and Lanzhou in Gansu. Among them, lilies from the first three production areas taste slightly bitter, while Lanzhou lilies taste relatively sweet and moist. Generally, Lanzhou lilies are eaten. Because Lanzhou lilies have relatively high environmental requirements, for example, they have strict requirements for soil, moisture, and elevation, and are difficult to survive under ordinary conditions. Before 1997, the lily planting area was only 30,000 mu. The lily growth cycle is relatively long, generally 3-6 years, and at least 5,000-9,000 yuan must be invested in them. Calculated this way, their price is naturally relatively expensive, which also limits the large-scale sale of lilies in supermarkets.”
So can an edible lily variety with high quality and high yield be bred so that it can also grow well outside Lanzhou, allowing more people to grow lilies and eat lilies?
After dedicated research by relevant experts, a new variety combining high yield and edibility was finally cultivated. It can increase yield by 30%-60%, with an annual yield of 3,000 kg/mu, fully 9 times higher than before. It is not only high-yielding but also excellent in quality, and its various nutritional components are no less than traditional edible varieties. In particular, these varieties have especially strong edibility, are both drought-resistant and waterlogging-resistant, and are also resistant to freezing and wind, so they have been successfully promoted and planted in Guangdong, Gansu, **, Heilongjiang, and other places. For the lily planting industry, it is almost a revolution, with a great impact on agricultural production and at the same time increasing farmers' income.”
Due to the biological characteristics of lilies, dense planting results in small size, while sparse planting results in large size. Lilies like shade, so they can grow better under dappled shade. Their branches and leaves form a good shading environment for themselves, improving the field microclimate, lowering soil temperature, and benefiting root development and bulb enlargement, which can correspondingly increase yield.
According to the growth habits of lilies, relevant experts have also explored a set of efficient lily planting models, that is, intercropping lilies with other crops. Lilies are shade-tolerant plants and can grow normally even under 98% shading. Therefore, lilies can be intercropped with grain crops such as soybeans, wheat, and corn, and can also be intercropped with economic plants such as pagoda trees, chestnuts, prickly ash, apples, persimmons, and jujubes. In particular, intercropping with poplar trees has achieved unexpected results. Because in the wild state, plant growth is a community formed by many combinations together, and lilies happen to need a shaded environment. Lilies are generally applied with 100 jin of chemical fertilizer per mu, and also a lot of organic fertilizer. These fertilizers cannot all be absorbed and utilized by lilies. Some will sink through watering and rainfall. Poplar trees have deep roots, can relieve soil compaction, and at the same time make use of wasted fertilizer. With sufficient water and fertilizer, poplar trees grow especially fast and especially large. The intercropping model of lilies and poplar trees has great results, high yield, and short return time, greatly increasing farmers' enthusiasm. The intercropping model of lilies and fruit trees can be said to have solved a major problem for the planting industry.
Lilies have strong adaptability and high economic benefits. They are a good project for farmers to become prosperous. Through the development of lily planting, many farmers have already lived prosperous lives.
