Advances in Researching Cultivation Techniques on the Hyperaccumulators Phytoremediation of Heavy Metal

Using phytoremediation technique to remove contaminants from soil had become a topic in current research.This article expounded the domestic and oversea research progress of hyperaccumulators on cultivation techniques and was systematically elaborated from many aspects,including variety selecting,seedling breeding,fertilizing (nitrogen phosphorus and organic fertilizer),usage of chelator and ameliorant,polyploid breeding,etc.The direction of hyperaccumulators research is put forward that the aboveground biomass and the heavy metal accumulation quantity should be raised through improving cultivation measures,meanwhile a new idea about research of plant tissue culture has been come up with.
