摘　　要：选择我国北方主要粮食作物冬小麦和夏谷进行盆栽试验,研究了土壤镉污染对作物生长发育和产量的影响及泥炭、羊粪两种不同类型的有机肥缓减土壤镉污染危害的作用;分析了镉在两种作物不同器官中的迁移效率和累积规律;认为施加有机肥是缓减土壤镉污染危害的有效措施。This paper selects the main grain crop in Northern China-the winter wheat and millet, with the method of pot-planting experimnet, research the influences of soil cadmium-pollution on the growth and yield of crop. It also studies the action of peat and goat feces rduce the hurt of soil cadmium - pollution and the law on cadmium accumulation and remove efficiency in various organs of crop. The study shows that organic fertiliser could reduce the hurt of soil 'cadmium-pollution and the effect of goat feces is better than peat.
