摘  要:
为研究络合剂木醋液(wood vinegar,WV)和EDTA对转基因印度芥菜修复重金属污染土壤的影响,采用田间试验方法,对不同种类的印度芥菜分别浇WV和EDTA,以浇清水为对照,研究重金属在芥菜不同部位的分布。结果表明,与对照相比,EDTA显著提高了Cu、Zn、Cd、Pb的转移系数,而WV未能提高Cu、Zn、Cd、Pb的转移系数;EDTA和WV均能显著提高印度芥菜3个品系对Cu、Zn和Cd的修复效率。

摘  要:
A field experiment was performed to study effect of various chelators(wood vinegar and EDTA) on remediation of heavy metal-polluted soil with transgenic Indian mustard.Transfer efficiency of Cu,Zn,Cd and Pb in 3 lines of Indian mustard was enhanced due to application of EDTA.However,transfer efficiency of heavy metals was not increased when wood vinegar was applied to 3 lines of Indian mustard.Application of EDTA and wood vinegar significantly increased remediation efficiency of soil with Cu,Cd and Zn by 3 lines of Indian mustard.
