Peanut high yield eight strokes

First, select good breeds. Select high-yield and high-quality new varieties, such as Luhua 14, Huayu 16, 8802-1, and Double Flower 20.

Second, deep plowing, full base fertilizer. Before arable land, a layer of farmyard fertilizer is applied first, applying 2,500 kg per 667 square meters. At the same time, 15 kg of urea per 667 square meters, 50 kg of superphosphate, and 15 kg of potassium chloride are combined and ridden.

Third, to ensure a reasonable density. According to the peasant film, the ridge length is 90 cm and the ridge width is 70 cm. Two lines of peanuts are planted, and the number is about 7400 per 667 m2.

Fourth, peanuts topping. During the planting period, the main stem was trimmed away leaving only the first two pairs of lateral branches. After removal of the main stem, the first pair of lateral branches increased by 1.2 to 2.7 cm, and the second pair of lateral branches increased by 9 to 10 cm, and the output increased by 10% to 14%.

Fifth, fat soil pressure branches. In the late flowering period, select sunny afternoons, press a pig, sheep manure and a small amount of phosphate fertilizer in the middle of the flower tree, then press two or three soils. Irrigate soil after irrigating first.

Sixth, spraying paclobutrazol, reasonable promotion and control. 30 to 50 days after flowering, peanuts were sprayed with paclobutrazol at a concentration of 0.1% in order to control the growth and prevent lodging of the depression.

Seven, foliar spray fertilizer. An efficient and quick-acting foliar fertilizer, such as potassium dihydrogen phosphate, is sprayed at the flowering stage, the lower needle stage, and the pod stage.

Eight, to meet the cone. After covering the first batch of fruit needles without covering the peanuts, the second batch of fruit needles was smashed and soiled when they were just grown. The second flowering period was high earth soil.
