花生是我国的主要油料作物之一,在我国华北、华中、西南等地区均有栽培,但一般多种在土地比较贫瘠的地块上,施肥水平很低,甚至不施肥,耕作比较粗放,因此产量不高,一般每亩只有100—150千克。近年来在花生栽培上应用了地膜覆盖,使产量有了较大的提高,但是由于地膜烂在地里不容易清除,残留量很大,因此土壤污染十分严重, Peanut is one of the main oil crops in China. It is cultivated in North China, Central China, Southwest China and other regions. However, most of the peanuts are cultivated in relatively barren land, and the fertilization level is very low. Yield is not high, usually only 100-150 kg per acre. In recent years, the peanut cultivation applied mulching, so that the yield has been greatly improved, but because the rotten film in the ground is not easy to remove, the residue is very large, so the soil pollution is very serious,
