| 摘 要： | 通过盆栽实验研究了铅（Pb）、镉（Cd）、铜（Cu）、汞（Hg）和砷（As）污染条件下，温郁金和种植土壤中重金属含量，分析了植物对重金属的吸收富集能力。结果表明，随着土壤中污染物的投加量增强，Cu、Pb、Cd、As元素主要集中在根部，而Hg元素由于其极易挥发的特性，其块根中含量反而随着Hg投加量的增加而减小。温郁金对不同元素的吸收富集能力不同，对Cd的富集能力最强，对Hg的富集能力最弱。

| Abstract: | The determination of the metal contents in treatment of lead,copper,arsenic,mercury and cadmium by pot experiments and bioaccumulation were studied in Curcuma wenyujin plant.The results indicated that increasing the treatments contents of five elements,Cu,Pb,Cd,As mainly focused in roots of plant whereas Hg content decreased because of its evaporation.The bioaccumulation of Curcuma wenyujin were difference with the elements different and the highest was Cd,while Hg was the least. |
