What is the planting distance of Lily

Lily propagation methods mainly with sub bulb propagation, how to plant lilies, it seems to introduce below.

1. Seed selection

When harvesting, the bulblet with developed root system, large size, compact scale, white shape, no damage, no disease and insect pests was selected as seed. The seeds can be soaked in agricultural streptomycin for 30 minutes, sprayed with 800-1000 times carbendazim for 30 minutes, or soaked in 2% formalin for 15 minutes, and then seeded. The most suitable planting season of lily is from September to October of lunar calendar. Planting at this time can make full use of the effective temperature before winter to promote the growth of taproot, which is conducive to its early spring emergence.

2. Plant spacing

When planting, open shallow hole (13cm) planting, general row spacing of 25-30-40 cm, plant spacing of 17-20 cm. Cover soil 7-10 cm. Then the mixed ash of the planting fertilizer soil is piled up among the plants, and the rotten fence manure is spread on the border. Cover with a layer of fallen leaves or straw to prevent freezing and moisturizing. There are 1-15000 plants per mu, and the seed amount is 150-250 kg. It takes 2 years (Hunan) or 3 years (Lanzhou) to propagate with scales, bulbils or corms in Shaoyang and Lanzhou. The seed bulbs were cultivated and then transplanted, and harvested after 2 years of growth.

3. Management

① Early management. In winter, choose sunny days for cultivation, sun the surface soil, and keep moisture and heat preservation. Before emergence in spring, the soil should be loosened and weeded to improve the ground temperature and promote the early emergence of seedlings. Eliminate weeds and prevent the erosion of heavy rain, and do not let the surface soil harden. In summer, it is necessary to prevent the rot caused by high temperature, keep the temperature cool and prevent frost, and apply fertilizer to promote the growth of lily. Generally, it is cultivated 2-3 times from sowing to excavation. In the middle stage of growth, loosen the soil 2-3 times to loosen the soil, remove weeds, and combine with soil cultivation to prevent bulblet exposure.

② Middle and late management. First, ditch cleaning and drainage. Lily most afraid of waterlogging, should often clear ditch drainage, to stop rain, soil waterlogging dry. The other is timely topping. One strong bud should be kept when Lily sprouts in spring, and the rest should be removed to avoid bulb division. Before and after Xiaoman, when the height of the seedlings reached 27-33 cm, the top should be removed in time to control the growth of the above ground parts, so as to promote the growth of underground bulbs with concentrated nutrients. For varieties with bulbils, if they do not plan to propagate with bulbils, they should be removed in time before and after grain cob seeds, combined with summer flower picking, so as to reduce the nutrient consumption of bulbs. The best timing is: when the flower bud changes from upright to drooping, the color changes from full green to pink on the sunny side. It's June. The third is to control the application of nitrogen fertilizer after topping. In order to promote the rapid hypertrophy of young bulbs. Before and after the summer solstice, the buds should be removed and the soil moisture should be cleaned up to reduce the field temperature and humidity. Picking flowers and topping.

③ In January, before the beginning of spring, when the lily seedlings were not unearthed, about 1000 kg of human manure and urine were applied to promote the growth of roots and strengthen the roots. In the first ten days of April, when the height of lily seedlings was 10-20cm, 500 kg of human and animal manure, 150-250 kg of fermented cake fertilizer and 10-15 kg of compound fertilizer were applied per mu. The third time is suitable to apply Zhuang Pian fertilizer, which is in the first and middle of June after Xiaoman. After flowering and topping, 15kg urea and 10kg potassium fertilizer are applied per mu to promote the growth of scales. At the same time, 0.2% KH2PO4 was sprayed on the leaves. It should be noted that the topdressing should be completed 40-50 days before excavation. After the winter vegetables Interplanted in autumn are harvested, manure is applied once in combination with loosening soil; after emergence in spring, manure is applied 1-2 times to promote the early development of strong seedlings. Generally, 30-40 kg of diluted human manure water and 10-15 kg of phosphate fertilizer are applied each time.
