How to cultivate peanuts covered with plastic film? Method 1, preparation before sowing 1. Seed selection: Yuanza 9102 8908 to flower 142, drying fruit: drying fruit 2ml for 3 days 3 days, film preparation: purchase 60 cm microfilm, 3 Mu 4 kg per mu, Underground pest control: ① mixed with methyl isomaliphate or phoxim 3 m 4 with 0.5 kg of water, 20 kg of water, 30 kg of soil before ploughing, and ② with methyl isomers per mu. Phosphorus or phoxim is mixed with 2.5 kg of water and 25 kg of peanut seeds. 2. Formula fertilization according to the soil test results of peanut fields in our county, on the basis of 1000 kilograms of farm manure 1000 kilograms per mu and an increase of boron, zinc and molybdenum fertilizers per mu, the fields with a yield of less than 200 kilograms per mu (15-10-15) apply 25 kilograms of formula fertilizer per mu; the fields with a yield of 250 kilograms per mu and 350 kilograms per mu can apply formula fertilizer 35 kilograms per mu; for fields with a yield of more than 400 kilograms per mu, 40 kilograms per mu of formula fertilizer or other peanut special fertilizer can be applied. Third, sowing, chemical division 1, sowing date: from the end of March to the first ten days of April, sowing enough moisture to cover plastic film 2, density: one film double rows, row spacing 1 foot, plant spacing 6 inches, one hole with two grains. 3. Chemical weeding: spraying 50% Acetochlor 2mur3 with water per mu before film mulching, or spraying with 3 packets of water per mu after emergence; the fields with more sedges are sprayed with water with sand ridges or Bailongtong 3 packets per mu (only wheat can be planted in the latter crop). Field management 1. Film breaking period: peanut top soil with three fingers or blades to open a 1.5-inch hole. 2. In the period of clearing pier, when there are two compound leaves on the main stem after emergence, the soil pile on the film hole should be cleaned in time to make the cotyledons exposed outside the film. 3. Branch-picking period: when the main stem of peanut has 4 compound leaves, dig out the side branches under the film 4, control prosperity: 40 days after flowering, the plant height is more than 1.5 feet, and the field with prosperous growth can be sprayed with 15% paclobutrazol 1 and water. Disease and pest control 1, dead plant control: ① selected disease-resistant varieties such as Yuanza 9102; ② was sprayed with 40% carbendazim per mu after seedling completion and at the beginning of flowering. 2. Prevention and control of leaf spot: 40% carbendazim per mu was sprayed with water at the initial stage.
