Peanut cultivation techniques

1. Fine soil preparation and fertilizer application should be based on sandy soil with high soil fertility and convenient irrigation and drainage. Each farmhouse must produce 150 farmyard fertilizers, 100 kg of compound fertilizer and 2 kg of boron fertilizer. , According to the car width 5.2 feet, ditch depth of 0.6 feet ditch, so that the three ditch connected.
Second, the selection of high-yield and stable varieties should be selected with strong resistance, short growth period, suitable for close planting, high yield and stable yield, yield 300-350 kg.
Third, timely drought sowing and reasonable planting seeds before sowing, with 25 grams of ammonium per acre or 50 grams of peanut rhizobium dressing, can increase production by 10-15%, to do the same day seed dressing, broadcast the same day.
Fourth, optimize the formula fertilization According to peanut fertilizer law and soil, soil nutrient content, should be applied peanut special fertilizer, in the seedling stage and early flowering after fertilization than conventional fertilizer production by more than 10%. During the actual peanut period, 0.3% borax was sprayed. As a result, spraying 0.4% potassium dihydrogen phosphate solution increased the yield by 9-13%.
V. Vigorously promote plastic film coverage and chemical weeding and promote early flowering and lowering needle results, increase the fruit-filling rate and increase the weight of 100 kernels. At the same time, the growth period can be shortened, creating favorable conditions for the second high yield. Spring sowing film peanut 6 kg per mu film. Before laying the film, use 4 or 2 "Lasso" or "Dole" herbicide to spray 50 kg of sprayed surface and use weeding function. Cover the film after spraying to protect the topsoil layer containing herbicides.
Sixth, to strengthen the field management of pests and diseases in time to break the film exposed seedlings, check seedlings replant. The mulching film peanuts are planted 15-18 days after sowing. When the cotyledon is flattened, it is necessary to break the film in time in order to prevent the high temperature from burning seedlings. The timely replanting of the ridges and ridges in the field. To timely cultivating and weeding, clear the ditch after rain, keep the soil air permeability, increase the temperature, which is conducive to the early formation of rhizobia, and to promote early growth. For peanut-enriched bacterial wilt, 40% carbendazim 500-fold or chlorothalonil 600-800-fold can be used. The main stem was manually picked at the planting stage and the main stem above the two pairs of lateral vines was cut off with a sharp blade.
