摘要
Abstract
Three kinds of Asteraceae herbaceous plant Zinniaelegans,Tagetes erecta,Centaurea cyanus were tested through comparison test under six cadmium (Cd) application levels (0、5、10、20、40、80 mg/kg) in greenhouse pot experiment to study the response and remediation effect of the herbaceous plants.Experimental results showed that low cadmium contcnt may promote the growth of plant;Cadmium restoration of three plants are increased with the increasing concentration of Cd,and followed the order of Zinnia elegans ＞ Tagetes erecta ＞ Centaurea cyanus.The study suggested that Zinniaelegan sand Tagetes erecta are good candidate species for phytoremediation of Cd contaminated soil because of their high tolerance,resistance,transfer and accumulation ability of Cd.关键词
