The main points of cultivation of Dragon Tooth Lily

I. Variety characteristics

Longya lily, also known as musk lily, sweet lily species, aboveground high 80~110cm, leaves long 10~18cm, white flowers, bulbs nearly spherical, single weight 250mm 500g, white, scales narrow and thick, tight, white delicate, good quality, with special flavor, fast growth, early maturity, generally 667m, can produce fresh scales 2000kg.

2. Cultivation techniques

The main results are as follows: 1. Soil preparation and fertilization: it is appropriate to choose sandy loam with fertile soil and good drainage, high ridge or sloping land, and rotate once every three years. The previous crops are melons and beans, cereals, and the rotation of onions and garlic. It can be intercropped with autumn and winter vegetables such as spinach, lettuce or cruciferous vegetables in the same year. As for open field cultivation, plastic film mulching can also be used to produce seedlings 7-15 days earlier and increase production. Deep turning over 25cm, applying lime 50-60kg in 667m2, making border width 1.8m-2.0m, ditch depth 40cm, opening planting holes or ditches according to plant spacing, applying organic fertilizer 2500~3000kg, 50~100kg, 20~30kg, and covering soil on them. The plastic film planting is suitable for scattered application and is shaped into the back of the tortoise.

2. Sowing and seedling raising: starting from the previous 3 years, the pest-free and damage-free bulbs were selected as seed bulbs, and the scales were peeled off and buried indoors with wet sand for 30 days to promote germination. After late September, the seeds that had already taken root and small scales were sown into the soil. The scales were concave facing upward when sowing, sowing one piece every 3-4cm, oblique sowing into the soil, deep 3-4cm, covering the soil with film or straw after covering the soil, and sowing again after being dug out in late August of the following year. Row spacing 15~20cm In the third year, after the leaves withered in the first ten days of August, the big ones were used as seed bulbs, and the small ones continued to be cultivated for another year.

The suitable sowing time is from August to September, and the seed bulb with strong, white scale, tight clasping, single bulb weight 50-60 g, row spacing 30~33cm, plant spacing 15-20cm, planting ditch depth 10-12cm, basal fertilizer is applied layer by layer, first put a layer of fertilizer at the bottom of the ditch, cover a layer of soil, cover soil thickness 3cm after sowing, then cover rice straw for heat preservation and moisture, sow or plant intercropping vegetables. Plastic film cultivation, the bed will be leveled, fine, stick to the ground to cover the film.

3. Field management: winter combined with fertilizer management of intercropping crops, ploughing and weeding, topdressing. Before the Beginning of Spring, the rotten human feces and urine 1000kg was collected every 667m2, and the cover grass was removed when the seedlings were divided. When the seedlings were 33cm high, the rotten and withered cake fertilizer 150kg and phosphorus and potassium compound fertilizer 10kg were applied deeply in the rows or beside the trees, and the soil was collected and cultivated. The seedlings covered with plastic film were broken and emerged in time, and when the surface soil temperature of 5cm reached 25 ℃, the plastic film was removed in time. Clear ditches and drainage to prevent waterlogging. In late June, every 667m2 was watered with 500kg human and animal manure water and proper amount of urea on a sunny day. Foliar topdressing was applied twice in late July when the weather was dry, and stopped 50 days before harvest.

After emergence in early March, only one strong seedling was left for each plant, and the rest were removed. From late May to early June, when the plant had about 60 leaves, the top was removed. If buds appear in late June and early July, the buds should be removed in time.
