Cultivation and management of health vegetable lily
Lily is a perennial plant of Liliaceae. Its underground bulb contains a large amount of protein, fructose, and pectin substances, which can be eaten freshly, and can also be extracted from starch, canned or processed into dried lily. Fresh stalks have the effect of supplementing replenishing qi, nourishing yin, moistening the lungs, relieving cough, and reducing asthma. It is an emerging health-care vegetable variety that is hot on the market and is loved by many people. The market price is more than 20 yuan per kilogram. The benefits are substantial and the development prospects are broad. Lily has a wide adaptability to climate and soil, likes cool weather, stems are not tolerant to frost, more drought tolerant, and the water requirement is not strict. The optimum temperature for plant cultivation is 15 to 20°C. It is best to use a thick layer of soil with good drainage. Sandy soil cultivation. Its bulbs grow rapidly, with a pure white color and good commercial performance. 1. The site for planting basal fertilization should be selected from sandy loam with good drainage and deep soil layer. It should not be used as a continuous crop in order to prevent crop blight. The soil layer should be deep-turned over 20 cm and full of organic fertilizer should be applied. Second, planting bulbs lily more than asexual reproduction, 2 to 3 years after planting into a commercial bulb. Generally sowed at a ground temperature of about 20 °C, before sowing with 100 kg of water to add copper sulfate and 0.5 kg of lime, and then soak the bulb into the solution for 10 to 20 hours to kill bacteria and promote rooting. Planting density spacing 30 ~ 40 cm, spacing 20 ~ 30 cm. After the ball is planted, fill the soil around it and apply base fertilizer between the plants. This will avoid direct contact between the fertilizer and the bulb, so as not to cause bad planting. Cover the soil after sowing and cover the bulbs. In order to prevent freezing and keep it moist, cover with straw or Other weeds. Third, the field management after the emergence of rice straw, trench fertilizer, fertilizer can not contact the bulb. Only one of the strongest buds is left after budding, and the remaining buds are removed to prevent the bulbs from cracking. Between the rows can be melons or legumes, cool shade for the lily. When the height of seedlings is 20-25 cm, top-dressing cultivators are used to promote the growth of stems and leaves, while the soil is used to protect exposed scales. When budding, it enters the expansion of bulbs, and it is time to apply a stack of organic fertilizer. A 0.2% potassium dihydrogen phosphate and 0.1% urea mixture was sprayed on the foliar to prolong the life of functional leaves. When the plant height is about 50 centimeters, it will be topping, inhibiting the growth of stems and leaves, and promoting bulb enlargement. At the same time, the buds should be removed in time to reduce nutrient consumption. During the high temperature in summer, the ground should cover grass, reduce the ground temperature and reduce the evaporation of water. During drought, the water should be sprayed every 5 to 7 days. It is advisable to use furrow irrigation to reduce soil compaction. Drain water after rain. Fourth, the harvesting of the above-ground part of the plant is completely withered and the bulb has been fully matured. Harvesting is not only of high yield, but also the product is resistant to storage. Generally, the yield per mu can reach more than 1,000 kg. V. Diseases and pests control The main diseases of lily are blight and soft rot. The blight can be controlled with 1000 times of Prok, and soft rot can be treated with 800 times of Carreton. Its insect pests are mainly detritus, which can be treated with BT emulsion 500 times or phoxim 1000 times.
