High-yielding cultivation film peanut
Peanut mulching technology can significantly improve yield, generally 250-300 kg per 667 square meters, high yield of 400 kg, film generally increase production by more than 20%, but also can improve the quality of peanuts, increase peanut oil and protein content. Specific measures are as follows: 1. Soil fertigation. Peanuts should not be re-slaughtered. Generally, continuous production for 2 years reduces production by 10%, and continuous production for 3 years reduces production by 30%. Therefore, it is not suitable for long-term continuous cropping. It is necessary to exchange crops with other crops for rotation. To ensure the quality of the coating, the preparation site must be fine, and plowing 20 to 30 cm. Many times, to ensure the Panasonic soil on the soil, good permeability, according to the level of peanut production, soil nutrients such as the lack of fertilization determine the amount of fertilizer, each production of 50 kilograms of basic fruit need to absorb 3 kg of nitrogen, phosphorus 0.5 kg, potassium 1.5 kg, of which about half of the nitrogen is from Rhizobium. Fertilization is mainly organic fertilizer, supplemented by chemical fertilizers. It applies 3,500 to 4,000 kilograms of high-quality soil miscellaneous fertilizer per 667 square meters, 5 kilograms of urea, 20 kilograms of superphosphate, 6 to 8 kilograms of potassium chloride, and soil miscellaneous fertilizer mixed with chemical fertilizers. Combined with site preparation and application. 2. Selection and selection of membranes. The width of the film to be selected is 85 to 90 cm, anti-aging, not broken, good transparency, thickness 0.007 mm, good shop spread, non-stick roll. Among the peanut varieties, the flowers of medium-early-maturing large fruits 17, Haihua 1, Xuzhou 68-4, Hua 37, and Luhua 9 were used. 3. Do pods and sowing. Site preparation is done in combination with rakes, rakes 10 to 12 centimeters high, rake bottoms 80 to 90 centimeters wide, rakes are flat, rake slopes are steep, and hole drilling is used; the other is mulching after sowing, requiring ridge width and mulch specifications adapt. Film quality standards are: è¶å¢’, auxiliaries, tension, affixation, and compression. Appropriate sowing date April 5-14, before planting, seed selection, drying seed, seed treatment, and then drilling according to the density specifications sowing, 2 per hole. When sowing, every 667 square meters spray control weeding agent cable 100 ~ 150 ml or Nong Si it 100 ~ 150 ml, spray 50 ~ 75 kg of water evenly. According to the characteristics of the species, the plant is suitable for dense planting. The medium-fertility plots are planted with medium-to-medium fruit varieties, ranging from 1 to 12,000 holes per 667 square meters, and large and medium-sized fertility plots, with 7500 to 9200 holes per 667 square meters. 4. Field management. Seedling stage in the bud seedling top soil and the main stem 2 when the real leaves open seedlings, after opening the film to cover wet soil seal Yan, soil thickness 3 to 5 cm, induced seedling unearthed; found seedlings in time to replant, poured Good key water. When the droughty season occurs during the fruiting stage and fruit ripening period, the leaves of the peanuts become dark green, the flowering amount is reduced, the noon leaves are wilted, and the sunset cannot be restored. At this time, the soil should be ditched immediately to protect the roots and preserve the leaves, and the leaves should be increased. And full fruit index, spray longer than the long control of the branches. In 40 to 50 days before the peanuts began to be sprayed, the surface spray of 1000 mg/kg was 50 kg more than that of the long-lasting liquid. Controlled the promotion and prevented the fields from lodging. In the late stage of scab, every 7 to 10 days, the foliar spray once 0.1% urea and 2% to 3% superphosphate mixed solution or 0.2% to 0.4% potassium dihydrogen phosphate solution 2 or 3 times, control Pests and diseases, the main pests and diseases are peanut blight, leaf spot, rust, maggots, etc., and pay attention to rats.
