沙化土地覆膜种花生产量高沙化土壤漏水漏肥，有机质含量低，不能满足农作物生长对土壤养分的需求，农作物产量低而不稳。采用地膜覆盖种植花生，则投入少，产量高，效益好。据对比试验，覆膜花生每公顷产量可达５２５０公斤，比不覆膜花生增产３０００公斤，投入仅增加７... Sandy Land Covering Film Peanut Yield Highly sandy soils have leakage and leakage of nutrients, with low organic matter content, which can not meet the demand of soil nutrient for crop growth. The output of crops is low and unstable. The use of plastic mulching planting peanuts, less input, high yield, good efficiency. According to the comparison test, the peanut-coated peanut can yield 5250 kilograms per hectare, an increase of 3000 kilograms more than that of the non-peanut-coated peanut, and an increase of only 7 ...
