修复重金属污染土壤的超富集植物栽培措施研究进展*

 利用植物修复被重金属污染的土壤是当前国际学术界的热点研究领域。从超富集植物的品种选择、幼苗繁育、施肥(N,P肥和有机肥)、螯合剂和改良剂的使用、土壤水分条件、群落构建、采收时间等方面,系统地阐述了国内外关于超富集植物栽培措施的研究进展,提出了通过改善栽培措施,提高超富集植物地上部分生物量和重金属积累量的研究方向。

Advances in Researching Cultivation Techniques on Hyperaccumulators Phytoremediating the Heavy Metal Contaminated Soil

Phytoremediation technique using plants to remove contaminants from soil has become a topic in current research. The research progress on hyperaccumulators' cultivation techniques was systematically elaborated from many aspects,including variety selecting,seedling breeding,fertilizing (nitrogen phosphorus and organic fertilizer),usage of chelator and amendment agent,soil moisture condition,construction of ecological communities and collecting time. The direction of hyperaccumulators' research was raised by improving the aboveground biomass and the heavy metal accumulation quantity through improving cultivation measures.
