Lily is a perennial herbaceous bulbous plant of Liliaceae. It is mainly distributed in the northern hemisphere temperate regions of eastern Asia, Europe, North America, etc. More than 100 varieties have been found all over the world. China is its main source of origin, with more than 50 origins. It is the natural distribution center of Lilium. In recent years, there have been many new varieties produced by artificial hybridization, such as Asian lily, musk lily, and perfume lily. The main application value of lily is ornamental, and some varieties can be eaten and used as vegetables. First, land preparation and land preparation Choose plots with higher topography, sunny, better irrigation and drainage conditions, deep soil layers and unreduced tops of fertility. Before ploughing, apply 450 kg of organic fertilizer per acre, 150 kg of calcium, magnesium and phosphorus, and then plow 25 to 30 cm. After the fertilizer is rotted, deep ploughing is carried out to mix the base fertilizer and the soil, improve the physical and chemical properties of the soil, and create favorable conditions for the full development of the lily roots and bulb expansion. Combined with the preparation of the trench to make the raft, the width of the raft is 1.4 to 1.6 meters, which requires convenient irrigation and drainage. Second, the choice of bulbs Lily is planted in vegetative bulbs with large, medium and small bulbs. Generally, the economic benefit of planting bulbs with 50-60 grams is the best. When selecting seeds, pay attention to: 1 select 3 to 5 bulbs to prevent the degradation of the species; 2 select the bulbs without brown necrotic plaques to prevent the disease from causing the lack of plants. Third, the appropriate sowing The sowing period of lily should start from the end of September to the beginning of October to the beginning of March of the next year. In the red soil hilly area of ​​southern China, the planting size is 4030 cm, ensuring a population density of more than 6,000 per acre. Sowing should be done while ditching and covering the soil with a thickness of 3 to 4 cm. After sowing, the plot must be kept dry and there must be no water. Fourth, strengthen field management 1. Topdressing and drainage Lily during the wintering period, before the freezing, the urea is 20 kg of urea and 30 kg of potassium chloride, and the bait is added. At the same time, the drainage ditch is combined to clean the drainage, so that the drainage is smooth, the water in the field is prevented, and the lily is reduced. Harm and rot. In the spring, apply top dressing twice before emergence, using 50 kg of ternary sulfur compound fertilizer or 2.5 kg of sulfur per acre. After emergence, lay a layer of grain grass in the field to prevent soil compaction, and at the same time play the role of moisturizing, fattening and cooling. 2. Covering the lily with mulching film in early spring for 30 to 40 days, shortening the emergence period of lily for 7 to 15 days, increasing yield by 12%. 3. Picking the top of the stem at the right time is based on the number of leaves. When the plant has grown more than 60 leaves and the average daily temperature does not exceed 23 °C, the topping is most suitable. The experiment showed that the topping of the heart was higher than that of the non-picked heart. The picking of the heart was better than that of the late heart picking. The more leaves were preserved in the appropriate period, the greater the yield increase. 4. Prevent the early leaves of green leaves to prolong the life of functional leaves. At the late growth stage of lily, the green leaves have large bulbs and high yield. To this end, in the late June, when the bulbs were swollen and slowed down, the foliar fertilizer was applied once with 0.2% potassium dihydrogen phosphate and 0.3% to 0.5% urea mixture. 5. Pest control After 1 to 2 days of sowing, spray 50-80 grams of dichloramide to prevent weeds from growing. The main pests and diseases during the growth period of lily are tigers, aphids and viral diseases. In the early stage of viral disease, 1.5% of the phytopathogenic emulsion 1000 times solution, or the anti-toxic agent No. 1 300 times solution, once every 10 days, even spray 2~3 You can do it twice. The aphids after emergence are sprayed with 5% solution of 50% methamidophos EC, and can also be controlled with 40% omethoate. In late April, 6 to 8 kilograms of carbofuran or 0.5 kilograms of phoxim were used per acre to carry out underground insecticides.
