| 摘 要： | 研究了金华市郊长期施用规模化养殖场鸡粪的蔬菜基地土壤重金属的积累现状.结果表明,该基地土壤重金属(Pb、Cd、Cu、Cr)含量已有一定程度的积累,其中80%大棚土壤已处于污染警戒水平(2级).其中,单一元素Cd污染严重,80%的基地土壤重金属镉含量已达轻度污染程度;其他元素含量虽未超标,但都有一定程度的积累.

| Abstract: | Heavy metals accumulation on vegetable soil in suburbs was studied long-term applied by large-scale chicken farms manure.The results showed that a certain degree of heavy metal were accumulated in the base,80% of the greenhouse pollution already reached to the soil alert level of（2）.Cd pollution was serious,80% of base soil was polluted by cadmium.other element content has not yet exceeded,however,accumulated to a certain level. |
