| 摘 要： | 盆栽试验研究了海州香薷和紫花香薷在Cu、Zn、Pb复合污染泥沙土上的重金属耐性与吸收动态。结果发现,在Cu、Zn、Pb全量分别为223、1068、232mg/kg的土壤上,两种香薷植物地上部生物量随生长时间的延长其增长趋势明显,其中叶片积累的生物量略高于茎秆积累的生物量;在整个生长期中重金属含量呈现动态变化,重金属吸收量有增加趋势。

| Abstract: | Pot experiment was conducted to determine the characters of heavy metal tolerance and uptake dynamics of two Elsholtzia plants on a long term Cu, Pb and Zn mixed-contaminated soil. The results showed that on this Cu, Pb, Zn mixed-contaminated soils, the plant heavy metal concentrations were changed and heavy metal uptakes were increased in two Elsholtzia plants along with plant growth period. |
