1. The black soil does not require strict soils. It is suitable for planting in various soils with a pH value of 5.5-7.2, and is planted in soils with deep soil layers, good plough layers, good soil properties, and good drainage. it is good. Second, the plots of planting black peanuts should be ploughed 25 to 30 centimeters deep, combined with winter ploughing Mushi 2500 to 3000 kilograms of farmyard manure. In the next spring equinox, shallow cultivation of 10 to 13 centimeters began. It is necessary to work with the farmer and protect the soil. When the soil is 5 cm deep and the soil temperature is stable above 15°C, it can be sowed. Before sowing, it is necessary to carry out pesticide dressing: 50% of phoxim 100g mixed with 50kg of seeds can prevent pests; 40% to 50% of carbendazim 150 ~ 250g of seeds can be used to prevent stem rot. Third, black peanuts require ridging planting. Rigid planting can deepen the living soil layer, making it light-receive on three sides, raising the ground temperature and facilitating the growth and development of fruit needles and soil.

According to soil conditions, 8000 to 11000 acres will be planted. It is best to use the method of mulching. The height of ridge body is preferably 10-12 cm. It is not only difficult to maintain the ridge surface, but also the cover of the ridge slope is not strict, the pressure is not real and the plastic film is easily scraped by the wind. Too low is not conducive to drainage. Fourth, peanuts should be sprayed with herbicides in the soil within 1 to 2 days after sowing. V.
