摘要
重金属污染环境对人类的危害很大 ,对作物产量和质量也影响极大。在受重金属污染的土壤上 ,如果种农作物或其它植物 ,可采用排土客土法 ,也可施用化学改良剂或调整种植结构 ,改变耕作制度 ,减少重金属进入食物链。
Heavy metals pollute the environment and are hazardous to crops as well as people's health. To grow agricultural crops or other plants in such polluted land, it is common practice to replace the soil, apply soil modifier, adjust the planting structure, or change the entire cropping system, so that the heavy metals do not enter the food chain. In planting trees, shrubs, and/or sod grass in this kind of land, close attention should be paid to selecting those species that are most tolerant both to the existent air and soil conditions.
