摘　　要：为了保障菜地土壤的安全利用,修复菜地土壤重金属污染、降低蔬菜重金属含量,对籽粒苋-钝化剂联合修复系统对菜地土壤和西蓝花重金属含量的影响进行研究。结果表明,籽粒苋种植可以显著降低菜地土壤Cd、Pb、Ni含量(P<0.05);籽粒苋-钝化剂联合修复系统可以显著降低西蓝花Cd、Pb含量(P<0.05);西蓝花种植可以显著降低土壤Hg、Cr、Ni含量(P<0.05),不宜在重金属污染土壤中种植。In order to ensure the safe use of vegetable soil,repair heavy metal pollution in vegetable soil,and reduce vegetable heavy metal content,this paper studied the effect of grain amaranth-passivator combined remediation system on the heavy metal content of vegetable soil and broccoli.The results showed that the grain amaranth planting could significantly reduce the Cd,Pb,Ni content of vegetable soil(P<0.05).Grain amaranth-passivator combined repair system can significantly reduce broccoli Cd,Pb content(P<0.05).Broccoli planting could significantly reduce the soil Hg,Cr and Ni content(P<0.05),and it was not suitable for planting in heavy metal contaminated soil.
