High-quality and High-yield cultivation techniques of Lily

I. site selection and seed selection

The soil should choose sandy loam with high topography, deep soil layer, fertile soil, convenient drainage and drought resistance, and loose loam. The bulb should choose a bulb that is round and straight, the scales are white and tightly clasped, and there is only one bulb without diseases and insect pests.

II. Rational planting

One month before planting, the land should be turned deeply, so that it is flat, clean, fine and broken, and it should be made into a small high border with a width of 1 m-1.2 m. The border surface is slightly in the shape of a tortoise, and a good ditch and main ditch are opened. During soil preparation, 50 kg of quicklime is applied every 667 square meters to disinfect the soil. The use of trench sowing, sowing ditch depth of 13 cm, row spacing of 30 cm x 20 cm. After sowing, fully fermented and mature barnyard manure (1000 kg of fire soil ash, 250kg of human feces and urine, 100kg of vegetable wilt and 100kg of calcium superphosphate were mixed for more than one month) after sowing. Add 3% furan 4 kg-5 kg, 50% dimethazone 1.5kg to cover seeds, and then apply 2500 kg of rotten pig and cow manure every 667m2. Then cover the soil and flat beds and cover with firewood and grass to keep warm.

III. Fine management

Often clear ditches and drain stains to prevent the soil from being too dry and the soil temperature too high. When the seedlings were not unearthed in December, remove the mulch, pick a sunny day to loosen the topsoil, apply 1000 kg of human feces and urine per 667m2; in March, combine ploughing with 500kg ~ 1000 kg of human feces and urine for 10 times of water; in the first ten days of April, 45% potassium sulfate compound fertilizer was applied in shallow ditches on both sides of the planting line, and 45% potassium sulfate compound fertilizer was applied in the bulb expansion period in late May. 40kg ~ 50kg. After the occurrence of spring seedlings, only the strongest one is left, and the rest is erased in time; when the bud is 1ml / 2cm, the bud is removed in time.

IV. Prevention and control of diseases and insect pests

The main diseases of lily are Rhizoctonia solani, Botrytis cinerea, root rot, anthracnose and so on. They can be sprayed or irrigated with fungicides such as Bordeaux liquid (1buzol 200), Dysen Zinc, Sukeling and so on. Insect pests are mainly aphids and mites, and dichlorvos 1000 times solution should be sprayed in time after occurrence. Underground pests include grubs, root mites, golden needle insects and so on. Before seedling emergence, methyl isosaliphate and phoxim granules can be mixed with fine soil and sprinkled into the soil, and acephate and phoxim emulsion can be used to control them at seedling stage.

5. Harvest and storage

Harvest in sunny days from Greater Heat to the Beginning of Autumn and store at any time after harvest. The specific practice is in the dark room or using the basement, build a buried pit with bricks or cement, first spread a layer of sand at the bottom, about 2 cm thick, and then a layer of sand bulb, the first layer of lily root down, the root of the second layer facing up, the third layer of root facing down, arranged in order, the top covered with a layer of sand 15-20 cm thick. This can be stored until the beginning of spring the following year.
