First, the site selection site is selected for lands with high topography, sunny reach, good irrigation and drainage conditions, deep soil layer, and undisturbed fertility. Before ploughing, apply 450 kg of organic fertilizer, 150 kg of calcium, magnesium and phosphorus per acre, and then plow 25-30 cm deep. After the fertilizer is rotted, deep plowing is performed to thoroughly mix the basal fertilizer with the soil to improve the physical and chemical properties of the soil. This will create favorable conditions for the full development of the lily root system and bulb expansion. Combine with site preparation and ditching, with a width of 1.4 to 1.6 meters, requiring irrigation and drainage facilities. Second, the selection of bulbs Lily bulbs planted vegetative bulbs, large, medium and small points. It is generally best to use 50-60 grams of medium bulbs for planting. Care should be taken when selecting seeds: 1 Select lateral bulbs with 3 to 5 seeds to prevent seedling degradation; 2 select bulbs without brown necrotic plaques to prevent disease infections causing strains. Third, the appropriate period sowing lily planting period should be in late September to early October to the beginning of March the following year before the emergence of seedlings. In the southern red soil hilly area, the sowing size is 4030 cm and the planting density per acre is more than 6,000. Sowing should be done while planting soil on one side of the trench, and the thickness of the soil is 3 to 4 cm. After sowing, the land must be kept dry and there should be no accumulation of water. Fourth, to strengthen the management of the field 1. Liquor Lily Lily during the winter before the closure of 20 kg of urea mu, 30 kg of potassium chloride chase a wax fertilizer, combined with cleaning drainage ditch for earth rooting, so that drainage and communication, prevent the accumulation of water , Decrease lily decay due to wetness. In the spring, the top dressing is applied twice before emergence. Each time, the amount of sulphur-containing compound fertilizer is 50 kg or sulfur is 2.5 kg per mu. After emergence, a layer of Cereal grass is covered in the field to prevent soil compaction, and at the same time, it plays a role in moisturizing, maintaining fertilizer and cooling. 2. Using mulching for cultivation in the early spring. Covering the lily for 30 to 40 days can shorten the emergence period of lily by 7 to 15 days and increase the yield by 12%. 3. At the appropriate time, the number of leaves on the stem top should be taken as the criterion. When the plants have grown more than 60 leaves, the daily average temperature does not exceed 23°C. Tests have shown that picking at the top of the heart does not increase the output of the crop, and the harvesting of the appropriate period of harvesting can increase the production of the crop at the proper time, and the more leaves reserved during the appropriate period, the greater the increase in the yield. 4. To prevent the longevity of green leaves to prolong the lifespan of functional leaves. In the late growth period of lily, the bulbs of green leaves are large and the yield is high. For this reason, when the bulb expansion is slowed down in late June, 0.2% potassium dihydrogen phosphate plus 0.3% to 0.5% urea mixture is used to topdress the foliar fertilizer once. 5. Diseases and Insect Pest Control After sowing for 1 to 2 days, 50-80 grams of diclofenac is sprayed to prevent overgrown weeds. The main diseases and pests during the growth of lily are ground tigers, aphids, and viral diseases. In the initial stage of virus disease, 1.5% of plant diseases and diseases, 1000 times of emulsions are sprayed, or 300 times of antiviral agents are applied. Once every 10 days, even spray 2~3. Can be the second. After the emergence of the aphids with 50% methamidophos EC 1500 times spray, can also be used 40% omethoate control. In late April, 6-8 kg of carbofuran or 0.5 kg of phoxim was used per acre to kill insects underground.
