摘　　要：研究表明农作物吸收土壤中的重金属元素的难易程度 ,因农作物的种类不同 ,以及体内代谢方式的不同而有所差异。水稻、小麦和蔬菜中的重金属含量与土壤中含量的相关关系各不相同 ;由于水分存在状况的差别 ,在旱田和水田中的农作物对铜元素的吸收规律呈现出明显的不同。The correlative investigate and research make out that the cropper produced by the green foodstuff base in Huaian City is all green. The research also indicates that the cropper's absorbability of the heavy metal differs from the kinds of foodstuff and vegetables,and the method of the metabolism. The correlation of the heavy metal content between the cropper and soil is different in rice, wheat and vegetables. Because of the differences of moisture, the rule of the cropper's absorbability of copper gives obvious discrepancy in glebe and paddy field.
