Plastic film cover is a new technology for high-yield cultivation of peanuts, generally increasing production by 50-75 kilograms per mu and increasing the productivity by 25%-50%. The early harvest of mulching film peanuts has a high market price, and it can solve the problem of provenance of autumn peanuts, promote the development of the production of autumn peanuts and provide autumn seeds for spring sowing peanuts. Its cultivation techniques are as follows: First, select improved varieties. Peanut mulching peanuts generally choose "Oil Oil 71", "Oil Oil 523", "Yueyou 79" and other fine varieties is appropriate. Second, the election site preparation. Choose sandy loam soil with deep soil, convenient drainage and irrigation, good fertility, flat terrain, and no peanuts. The land is made of two plows and two plows so that it can be loose, finely chopped, smooth, and free of weeds. Third, apply base fertilizer. Basal fertilizer is mainly farmyard manure, with a certain proportion of nitrogen, phosphorus, and potassium fertilizers. After the first ploughshare, generally Mushi rotted 1500-2000 kg of farmyard fertilizer, 25 kg of superphosphate, 5-7.5 kg of urea or compound fertilizer, and then carried out the second plowshare. For acidic loam, appropriate amount of lime can be applied. Fourth, for seeding cover film. After fertilizing and leveling the soil, the surface is 100 centimeters wide, 15-18 centimeters high, 30 centimeters wide, and the seedlings are ready for sowing. Sowing time 10-15 days ahead of ground peanuts sowing, choose no pests, gap full of seed seeding, four rows of each seedling, spacing 25 cm, hole spacing 12-25 cm, sowing 2 per hole, acres broadcast 2 -2.5 million grains, then level the planting groove. After sowing, mu shall be sprayed evenly with 50% acetochlor EC or 25% caustic soda EC 150ml with 100 kg water, then cover it with a 150 cm wide plastic film flatly and tightly around the membrane to achieve moisturizing. Insulation, protection of the purpose of killing grass. Fifth, field management. 1. Draw seedlings out of the film: When the top soil of seedlings, in time with a blade in the hole to break a small 6 cm square mouth, so that the seedlings out of the film growth, small mouth around the film is still fine soil compaction. 2. Topdressing: In the flowering period, the surface of the leaves is sprayed with 3% calcium superphosphate clarified solution or sprayed with poems to promote scabbing of the lower needles and increase fruit filling rate. 3. Anti-Miao Long: For peanuts with leggy phenomenon, it can be sprayed with 0.1% of B9 to regulate and control. 4. Anti-drought and anti-staining: When the peanuts meet with drought, they can be slowly irrigated and penetrated from the sulcus to keep the soil moist. In rainy days, it is necessary to dredge irrigation canals in the field to prevent accumulation of water. 5. Pest control: The main pests are aphids, floorworms, Spodoptera litura, etc., which can be sprayed with 800 times liquid to prevent and control trichlorfon; the main diseases are rust, which can be sprayed with 800 times solution of chlorothalonil in the initial flowering period and sprayed every 7-10 days. Once, spray 2-3 times. Six, timely harvest. Recycling of residual film, timely harvesting, to prevent the growth of mature pods, moldy rotting, affecting the yield and quality, reduce the impact on the post-production and environmental pollution.
