植物富集重金属的影响因素研究

Study of influence factors of plants enriching heavy metals

重金属超富集植物的研究是治理重金属污染土壤的技术重点,是矿区复垦和生态重建的基础.本文就影响植物富集重金属离子的因素进行综述,探讨了温度、pH值、光照以及EDTA络合剂等对植物富集重金属离子能力的影响,以期为超富集植物筛选提供理论依据.

Study on heavy metal hyper-accumulator is the technical key to fight heavy metal polluting soil and the base of mine area reclaiming and ecological reconstruction.The influence factors are reviewed in plants enriching heavy metals.The influence factors,such as temperature,pH,light and EDTA etc,are discussed to provide theory basis for electing hyper-accumulators.
