High-yield cultivation techniques of Edible Lily

In order to obtain high yield of lily cultivation, the following technical links should be grasped in cultivation:

1. Select suitable varieties

Lily points edible and medicinal two categories, a total of more than 10 varieties. Edible lily to dragon bud lily quality is best, this breed scale hypertrophy, shaped like dragon tooth, white tender, no bitterness, high price, good market. Medicinal lily scales are generally short, low yield, bitter, can only be used as medicine. Therefore, when introducing edible lily seeds, we must choose white, large scale, no pitting, no bitter seed ball. Lily reproduction coefficient is low, with a large amount of seed, about 150 to 200 kg per mu seed ball.

2. Choose the right soil

Although lily adaptability wide, can be cultivated in a variety of soils, but the best choice for high terrain, drainage smooth, loose soil, fertile plot planting. Lily bogey continuous cropping or rotation with onions, garlic crops, the previous crop to leguminous or gramineous crops as well. Before planting, deeply turn the soil more than 25 cm, apply decomposed organic fertilizer 2500 - 3000 kg and calcium superphosphate 25 kg per mu as base fertilizer, and turn 50% of the soil agricultural 0.6 kg into the soil at the same time for soil disinfection. Fine rake flat after making high ridge or flat ridge, ridge width 2 meters, groove depth 30 cm.

3. Timely sowing

Lily seed is lily bulb, also called seed bulb. Lily should be sown in October. Before sowing, bulbs should be soaked in 2% formalin solution for 15 minutes. After taking out and drying, they should be sown. Row spacing 25 cm, plant spacing 15 cm, 10 cm deep, after sowing with straw or leaves covered moisture.

4. Field management

After planting to March of the next year (a total of 5~6 months) emergence, after sowing before the emergence of pre-emergence weeding, generally with glyphosate, butachlor and other dryland herbicides. Lily seedlings should not be further deep cultivation weeding, so as not to damage the root system. Can cultivate 1 to 2 times, the exposed lily should be cultivated in time. Before the beginning of spring, when the seedlings have not emerged, reapply fertilizer once, and apply 1000 to 1500kg of human excrement per mu. When the seedling height is 3 to 5 cm, the ground is covered with about 500kg straw per mu. When the seedling height is about 10cm, intertill and weed twice in time. After budding, a deep cultivation is generally carried out in early May, and attention is paid to cultivating soil. The height of seedlings is about 30 to 35cm, and the tops and heads are removed in time, mainly to control the reproductive growth of lily and promote the rapid expansion of bulbs. At this time, avoid blind topdressing, so as not to stem excessive length, affect bulb development hypertrophy, in order to concentrate nutrients to the bulb transport. After flower bud is removed, shallow cultivation is carried out once, and the depth is 4cm. When the seedling height is 20cm, apply fertilizer once, urea 10 - 12kg and potassium fertilizer 7.5 - 10kg per mu. In order to prevent premature senescence, 10kg of high-grade compound fertilizer was sprayed on 50kg of water in early July, and 0.2% potassium dihydrogen phosphate solution was sprayed on leaves. This was the key period for high yield of lily. Lily afraid of waterlogging, rainy season and heavy rain after timely dredging ditch system, drainage water. Leaf spot disease and bulb rot disease can be controlled by spraying 65% mancozeb 500 times solution once every 7 days, continuously spraying 3 to 4 times. Aphids can be controlled by spraying 40% dimethoate emulsifiable solution 1000 times, and root maggots can be irrigated with 90% dibai insect.

5. Reasonable interplanting

Interplanting lily growth period of nearly 1 year, winter can be interplanted radish, green vegetables, etc.; next May interplanting watermelon or sweet potato, conducive to loosening soil, reducing grub harm, promote lily expansion. Lily can be intercropped with soybean, wheat, corn and other food crops, but also with locust tree, chestnut, pepper, apple, persimmon, jujube and other economic trees, especially with poplar intercropping, received unexpected good results.

6. Timely harvesting and graded seed retention

After the beginning of autumn, lily stems turn yellow and die, flowers fall off when the harvest is appropriate. At this time, its bulbs are fully developed, with high yield and storage tolerance. Harvesting should be carried out in sunny days. The bulbs should be dug out and cut off from the ground. They should be immediately transported indoors and buried in clean river sand for storage to prevent discoloration and drying, which will affect economic returns. Harvesting strict seed quality control, so that seed selection work to achieve the combination of field and indoor, the implementation of commercial lily seed and seed lily seed single collection single storage, graded storage. Especially after harvest can not be exposed to the sun, so as not to affect the quality.
