【摘要】 利用螯合诱导植物修复技术,对土壤重金属污染进行治理是目前国内外有关学者研究的热点和难点。本文根据螯合剂的作用原理,系统地阐述了螯合剂对土壤重金属活性、植物吸收的影响,以及对植物富集重金属的作用,并通过对目前该项技术在重金属污染土壤修复中所存在问题的分析,提出今后螯合诱导植物技术修复治理重金属污染土壤的新思路。更多还原

【Abstract】 The remediation technique to enhance accumulation of heavy metal in plants,Chelate-induced phytoextraction have been emphasized in this paper. According to principle of applied chelators, this paper mainly introduced effect of chelators on heavy metals desorption in soil, accumulation in plant and translocation from roots to shoots. Besides, it could be inferred that more effective approaches of Chelate-induced phytoextraction of polluted soil can be developed and put into practice in principle of plant uptake heavy metal.更多还原
