Small planting take the bulbs and bury them directly in the soil in the fall, and they will germinate and bloom the next spring. Large-scale planting 1.Seed ball scale cultivation with a sharp knife to cut off the base of the scales, and then insert them into the seedbed of sandy loam soil. Inserted with the base facing down, each piece is spaced 3cm apart, and the top is covered with fine sand about 6cm thick. Water the soil regularly to keep it warm, but don't water it too much to prevent the scales from rotting. Keep the bed temperature at about 20℃. Autumn sowing in the south lasts for about half a month, with rice-sized bulbs appearing from the cut at the lower end of the scales. Plant 1 or 2 basal leaves the following spring. Dig again in the fall after the leaves have withered. According to the size of the bulb, a large single bulb weighing more than 25 grams can be used as a seed ball, and a small one can be cultivated for another year.2. Sowing is generally planted in the fall in the south, and in the spring in the north, but it is preferable to plant in the fall. In the north, flat beds or ridges are used, and in the south, raised beds are used for cultivation. Row spacing 20~40 cm, plant spacing 15~20 cm. Covering the soil after planting, the thickness of the top of the bulb 3~4cm is appropriate. 3. field animal management (1) cultivation and cultivation of lilies long growing period, the fall in the soil overwintering, the following spring out of the soil takes a long time. Therefore, the beds can be planted with vegetables and wheat crops. Interplanting harvest, loosen the soil, turn the grass once, to prevent weeds from growing, consuming nutrients, affecting the growth of lilies. Tilling 2~3 times in the middle of growth, combined with soil cultivation, to prevent discoloration of bare bulbs and scales. (2) After germination and seedling emergence in spring, fertilization once when the seedling height is 13-16 cm. After the last fertilization, spread straw thinly on the soil surface, using 400 kg of straw per mu to lower the ground temperature, maintain humidity, and prevent rain erosion and weed growth. (3) Remove tillers, pick buds and beads, top buds and keep buds strong during spring germination, and remove the rest to prevent bulb splitting. Summer buds begin to expand, should be pulled out at any time to reduce nutrient consumption. Varieties with bead buds, if you do not intend to propagate with bead buds, should be removed in time to avoid nutrient loss. In order to promote bulb expansion, to prevent flowering and stem overgrowth, you can also remove the top buds, inhibit the growth of the above-ground part, but it is best to remove the top in late May, not too early and not too late.4. Harvesting of above-ground lily of the valley stems and leaves began to turn yellow, the plant stops growing, the bulb is gradually maturing. When the upper part of the ground is all dead, the lower part of the leaves fall, and the upper part of the leaves fall, it is the right time to harvest. The south is harvested in August to September, and the north is harvested in early November. To harvest, dig up bulbs and remove roots, mud and stems. Transport indoors and cover with grass to avoid discoloration of the bulbs due to sunlight, which affects the quality of the product. Edible lily planting technology 1. Selection of land preparation: should choose fertile soil, high cool terrain, well-drained, loose soil sandy loam for cultivation. Combined with land preparation, each mu of organic fertilizer 2000 kg, 40-50 kg of Yangfeng compound fertilizer for base fertilizer. Lime 50-60 kg per mu (or 50% Yanong 0.6 kg), for soil disinfection. Then the whole piece of fine harrow leveling, made each bed width of 1.3m or flat beds, bed ditch width of 30cm, surrounded by deep drainage ditches, well-drained. 2. planting method mainly using bulb reproduction. Choose small bulbs with dense, white, regular shape, no damage, no pests and diseases as seeds. Soak the stems in 70% metribuzin, carbendazim or agricultural streptomycin solution for 15-30 minutes, sterilize, dry and plant. The best time is late September through October. On the finished bed, make a horizontal furrow with a row spacing of 25 cm and a deep furrow of 12 cm. Then place a small bulb every 15cm (plant spacing) with the top facing upwards, cover with fine soil, cover with soil and where possible add a layer of fallen leaves or straw to protect against frost and damp. Lightly press the leafy grass and remove when germination occurs. 15,000-15,000 plants per mu, 150-200 seeds per mu/kg. 3. Field animal management (1) Pre-management. In winter, choose sunny days to plow, dry the topsoil, moisturize and keep warm. In the spring before seedling emergence, loosen the soil and weed, raise the ground temperature, promote early emergence; cover the grass to maintain moisture. In summer, it is necessary to prevent rot caused by high temperature; in cold weather, it is necessary to do a good job to keep warm and prevent frost, and apply seedling fertilizer to promote the growth of lilies. (2) Mid and late stage management. First, clear the ditch and drain the water. The second is to shock the top at the right time. The best time is:When the flower buds turn from upright to drooping, the color of the sunny side changes from full green to pink. It is now June. The third is to control the application of nitrogen fertilizer after topping. Promote the rapid fattening of young bulbs. Before and after the summer, the pearl buds should be removed in a timely manner, clean up the ditch moisture, and reduce the temperature and humidity of the field. (3) Pursuit of fertilizer. The first time is a steady wax fertilizer. in January when the lily seedlings are not out of the ground, with the cultivation of mu of urea 5-10 kg, to promote new roots. The second time is to re-apply the strong seedling fertilizer. in early April when the lily seedlings are 10-20 cm high, plus 10-15 kg of Yangfeng compound fertilizer and 5-10 kg of urea per mu, to promote strong seedlings. The third time is the appropriate application of bulb expansion fertilizer. after flowering and topping in mid-June, 30-40 kg per mu of Yanfeng 48% urea-based compound fertilizer, to promote bulb hypertrophy. At the same time foliar spraying 0.2% potassium dihydrogen phosphate. Fertilizer should be completed 40-50 days before digging.4. Pest control (1) lily wilt One of the common diseases of lilies, rainy years is serious, resulting in stem and leaf rot, which seriously affects the yield of bulbs. Bacteria can damage stems, leaves, flowers and scales. When the base of the stem is damaged, it shrinks when exposed to water, causing the entire plant to wilt and die quickly. Leaves are diseased with watery, light brown, irregular spots. In severe cases, flowers, pedicels and scales are killed, resulting in discoloration and rotting of diseased parts. Prevention and control methods: ① crop rotation; ② choose well-drained plots with loose soil for cultivation; ③ seed ball disinfection; ④ strengthen field management, pay attention to digging ditches and drainage; apply phosphorus and potassium fertilizers to make the seedlings grow strong; ⑤ before the emergence of the seedlings sprayed with 1: 2:200 Bordeaux solution for 1 time, and after emergence sprayed with 50% carbendazim 800 times to protect the seedlings; after the onset of the disease, remove the diseased plants in time and treat them with 50% quicklime. After the onset of the disease, remove the diseased plants in time and treat them with 50% lime. (2) Viral disease affected plants are characterized by yellowing leaves or yellow spots and stripes, severe defoliation, poor plant growth and shriveling. Flower buds turn yellow and fail to open, and in severe cases the plants wither and die. Prevention and control methods:① Cultivate disease-resistant varieties or propagate disease-free bulbs; (2) Strengthen field management, appropriately increase the application of phosphorus and potash fertilizers, so as to make plants grow healthily and enhance disease resistance; (3) Uproot severely damaged plants, prevent and control aphids early, and reduce re-infection by infected aphids. (3) Leaf blight and soft rot are the main diseases in the growing and storage period respectively. Prevention and control methods:Choose healthy and disease-free seedpods for propagation, soak the seeds in a 50% benzimidazole 500-600 times solution for 20-30 minutes before sowing, and then dry the seeds after sowing. Try not to touch the bulbs during harvesting and transportation, and pay attention to ventilation and cooling during storage. (4) Common pests are aphids, beetle larvae and mites. Aphids are harmful and often gather on the buds of young leaves to suck the juice, causing the plant to shrivel up, grow poorly and blossom. Prevention and control methods:① Clean up the countryside and eradicate weeds in the field to reduce the overwintering population; ② In the period of occurrence, spraying 2,000 times of pyrethrin solution, 1,500 times of 40% oxidized lecithin solution, or 1,000 times of 50% malathion solution to kill aphids and lice is a great contribution. Malathion and Zinphos can be used on beetle larvae. Acaricides can be used to kill mites.
