摘要:
通过盆栽试验比较乙二酸四乙酸(EDTA)对印度芥菜修复镉(Cd)污染土壤的增效作用，探讨EDTA施入量与不同施入阶段对复合污染土壤中Cd、铅(Pb)、锌(Zn)的活化能力和印度芥菜吸收3种重金属的影响。结果表明：Cd添加量相同的条件下，EDTA的施入使印度芥菜生物量明显下降，地上部Cd吸收量明显增加，重金属提取量是未施入EDTA组的0.5~1.63倍，收获时土壤有效态Cd含量施入组低于未施入组；生物量和Cd吸收量随着Cd添加量的增加呈现先升高后下降的抛物线形规律，临界Cd添加量为120 mg/kg；EDTA一次性使用剂量为3 mmol/kg与分3个阶段施入 1 mmol/kg 相比，后者取得了最佳修复效果，Cd、Pb、Zn提取量分别是对照的1.13、3.78、1.29倍。将最优方案应用于微区试验，地上部重金属含量较对照显著增加，对Cd、Pb、Zn的提取量分别是对照的1.24、2.06、207倍。
