1. Soil conditions require deep plowing of soil, flat topography, convenient drainage and irrigation, suitable soil structure, good rationalization, organic matter content of 10 g/kg or more, alkaline nitrogen content of 40 mg/kg or more, alkaline nitrogen content of 40 mg/kg More than kilograms, available phosphorus content is 15 mg/kg or more, available potassium content is 80 mg/kg or more, soil pH is 6.5-7.5, and soil total salt content must not be higher than 2 g/kg. No cotton was planted in the previous three years. II. Irrigation conditions The plain farmland is prohibited from irrigating above-ground water sources, and the depth of groundwater source irrigation is greater than 50 meters. Upstream mountainous areas, there is no available ground water for industrial pollution. Third, cultivation technology 1, species selection: selection of high quality, high yield, disease resistance, strong adaptability, good commodity peanut varieties. Do not use genetically modified peanut varieties. 2. Seed treatment: shelling 3 days before sowing for 3 days before sowing, removing dark yellow grains, diseases and insects, and pods. Seed coating 0.3% seed coating. Each kilogram of biological phosphorus potassium fertilizer 1 kg seed dressing. 3. Seeding: Use 4000 kg of high-quality rotting organic fertilizer per acre, 50 kg of special fertilizer for peanut, deep plowing 20 cm, and leveling and making ridges. 5 cm soil temperature stable above 15 °C (small peanuts above 12 °C) sowing. The interplanting peanuts were sown 20 days before the harvest of the former crop, generally 9-12 kilograms per mu. Fertilizers should be thin and lean and dense, with 6000-10,000 strains per mu. When the cotyledons of the mulching film are unearthed, a small hole is blown and the plants are seen to have green leaves, and they are planted in the morning or in the evening. 4. Promotion and control: 4 kg of urea per acre is collected before the fruit needle enters the soil, two waters are poured in the full fruit period, and 15% paclobutrazol (250 mg water 1 kg) is sprayed once. A peanut fast organic liquid fertilizer was sprayed every 10 days during the whole growth period. 5. Pest Control: For brown spot, black spot, sun spot, anthracnose, etc., 50% Carbendazim WP 1000x or 80% Mancozeb WP 500x can be used at the beginning of the disease. 10% of the world's high water dispersible granules 50-80 grams (40-60 kg per acre of water) spray control, every 7-10 days interval, even spray 2-3 times. For rust, it is sprayed with 12.5% ​​carbazole (Super Poly) wettable powder 4000-5000 times at the beginning of the disease. Against the blight, can be used in the peanut seedling stage 5% Jinggangmycin aqueous 2000 times spray control. For viral diseases, the disease is treated with 1.5% Phytophage Emulsion 1000 times solution or 20% Virus A WP 500 times in the initial stage of disease, 7-10 days, and sprayed 2-3 times. For aphid transmitting viral diseases, when the rate of pods in the peanut field reaches 5%-10%, use 10% imidacloprid wettable powder 3000 times solution or 40% dimethoate emulsion 1000-1500 times solution or 25% acryl water to disperse Granules 5000-10000 times spray control. For Spodoptera exigua and cotton bollworms, they were sprayed with 25% to 3,000 times solution of 5% tetradichloromethane or 1500 times the amount of Bt wettable powder (16000IU/mg).
