Sweet hemp leaves, also known as leaves, are jute and jute leaves. Its nutrient-rich stems and leaves, taste bitter, cold, there is heat, Jieshu, bleeding effect, is a supplement of calcium and trace elements of health care wild vegetables can be fried, soup or hot pot material. My county has a long history of planting and eating and is deeply loved by consumers.
Sweet-leafed leaves are warm, moist, heat-resistant, and cold. The optimum temperature for the growing season is 25-28°C. The soil is not strict, but it is best cultivated in sandy loam with deep, fertile and well-drained soil. Its cultivation techniques are as follows:
First, soil preparation, full basal sweet and hemp leaves crude raw and easy to grow, but the high-yield cultivation should choose rich fertile organic soil loam, combined with deep plowing thick soil, Mushi decomposed organic fertilizer 2500 kg mixed superphosphate 15 kg, Potassium chloride 10 kg base fertilizer, built into a ditch 30 cm wide, 15 cm high, 1.5 meters wide sorghum width of the sorghum, the entire leveling fine crushed after the surface soil can be sown.
Second, live cultivation, Miao Miao Dingmao sweet leaves are mainly used live cultivation, "spring equinox" until after the "equinox" can be sown, the general mu per planting amount of 0.1 to 0.2 kg, can be drilled or sowing, sowing after the planting of faecal water Or urine, then cover. When the seedlings grow 3 true leaves and the seedling height is 10 cm, the seedlings can be transplanted, and the seedlings can be transplanted and replenished. The spacing between the post-emergence shoots is 20 cm 20 cm, and the seedlings can be 20 cm and 25 cm. Line spacing for transplanting, transplanting seedlings to be watered 1 to 2 times to ensure its survival, and then set the seedlings.
Third, the field of fertilizer management Sweet potato leaves grow slowly, the field is easy to breed weeds, must be timely cultivator, weeding, and early to strengthen fertilizer and water management. Based on the application of basal fertilization, field fertilization is mainly based on available nitrogen fertilizer, and appropriate amount of phosphate fertilizer is added. During the growth period, fertilize once every 12 to 15 days, and use 8 to 10 kilograms of urea to flush with manure. After entering the long-term prosperous period, the plant's water-absorption and fertilizer-absorption capacity is enhanced, and the combination of sweet and marijuana leaf growth should be used to fertilize and maintain the vigorous growth of the plants so as to increase the growth of the shoots and leaves and increase the yield. Sweet and sesame leaves should keep the soil moist during the whole growth period. After emergence, we must pay attention to clearing the sewers so that the irrigated water can flow smoothly, and keep the fields from collecting water in rainy days.
Diseases and Insect Pests The pests and diseases of sweet and pungent leaves mainly include wilt disease, anthrax, small earthworms, Spodoptera litura and roundworms, and must be used to prevent and treat pesticides. Anthracnose can be used 77% to kill 600 times or 70% carbendazim spray 800 times; fusarium can be used 75% chlorothalonil or 70% thiophanate-methyl 1500 times; small tigers can be used 3% Milur 1.5 Kilograms are applied at the site preparation; Spodoptera litura can be used 1000 times 50% phoxim, or 5% 5% Sitabao, or BT.800 times spray; locusts can be used 2000 times 2000 times, or 50% Pipa fog 1,000 times, or 40% dimethoate 1000 times spray.
V. Picking the sweet and ephemeral plant at a proper time When the plant grows to a height of 0.3 meters, it can begin picking, picking the stems and leaves of the main stem first, and then taking the tender stems and leaves of the lateral branches. Usually with 3 to 5 leaves, 15 to 20 cm long stems and leaves, harvesting period of 2 to 3 months, about 2,500 kg per mu.
