Lily cultivation and field management

Field cultivation and management of lily

When carrying out field cultivation, we should do a good job in the following aspects.

The main results are as follows: (1) the varieties should be selected according to the cultivation purpose, local climatic conditions, soil and other factors.

(2) choose suitable land: choose high and dry sloping land (small slope) or flat land, the soil is loose, deep, the content of organic matter is medium, and the land should have good drainage capacity.

Drought-prone plots should have a certain irrigation capacity.

In addition, continuous cropping of lilies is avoided. It takes 5 years for lilies to be replanted on plots that have been planted with lilies. Legumes and Gramineae are the best crops for previous crops, while Solanaceae and other lilies are generally difficult to grow lilies directly after harvest.

Lily soil treatment

After the harvest of the previous crops in ①, the crops should be ploughed and dried immediately in order to achieve the purpose of soil disinfection and increase soil fertility.

② should apply sufficient base fertilizer, mainly organic fertilizer (cow and horse manure, barnyard manure, chicken manure, etc.), can also apply some fully mature cake fertilizer, after application should be fully mixed evenly.

③ digs drains and heights. The height of the border is generally 20-30 cm, and the width is about 1.5 mi 2.0 meters. The gutter is 0.3-0.5 meters wide, and the border surface is made into the shape of a tortoise, low on both sides and high in the middle. The drains should be connected to each other so that the rain can stop drying after heavy rain.

Lily sowing period

It is suitable for mid-late September in the Central Plains; in alpine areas, it is too late, too little rooting before winter, not flourishing in the beginning of spring, and unfavorable emergence of seedlings; too early, the ground temperature is too high, and the bulbs are susceptible to disease and rot, resulting in lack of seedlings and weak seedlings. The general principle is to be early rather than late. The daily average temperature is about 20 ℃, and there is no high temperature above 32 ℃. The best sowing time is sunny day after rain.

Planting and topdressing of Lily

Planting:

① trench: the direction of the trench is perpendicular to the direction of the border, with a depth of 5-10 cm.

② seed ball: pay attention to protect the new root.

③ cover soil: the soil cover should be slightly higher than the border surface, in order to preserve soil moisture and drainage.

Topdressing:

① is mainly based on chemical fertilizers containing nitrogen and potassium, and some liquid organic fertilizers such as bean cake water can also be used. Lily generally does not apply phosphate fertilizer, which can be provided by organic fertilizer.

② fertilization period. One month after emergence, bean cake water and 0.5% ammonium sulfate were applied, and 0.2% potassium salicylate and 0.2% ammonium sulfate were mixed. After the bud appears, it can be fertilized outside the root and sprayed with 0.05% potassium nitrate solution. After flowering, chemical fertilizer can be applied again to facilitate bulb expansion.

Planting density and depth of lily

The planting density and depth of the field should refer to variety, use, soil quality, fertility and so on. In practice, we can refer to the following principles or ideas.

Small bulbs should be dense and shallow, ornamental use should be thin, cut flowers and food should be dense, clayey soil layer should be shallow, loose soil layer with poor water retention should be deep, and cold areas should be deeper in winter.

In general, the plant spacing is 15-30 cm, and the row spacing is 30-50 cm, which is about 4500 UV 15000 plants / mu, with a depth of about 5 cm.

Lily selected bulbs and sterilized

Before sowing, according to the natural growth of the bulbs, carefully separate the bulbs that grow together (a seed bulb can consist of 5 bulbs) with a bamboo knife or hand, and grade them according to their size. The big ones are sold, the small ones continue to breed, and the medium ones are planted. The size of the bulb varies according to the breed. Generally speaking, the diameter of the bulb varies according to the variety. The bulb with no diseases and insect pests, no damage, and no deformity should be selected as the bulb, and the original root system should not be damaged when separating the bulb.

Disinfection method: soak in carbendazim or carbendan solution of 1RU 500 for 20-30 minutes.
