| 摘 要： | 通过九组不同水平的重金属Pb、Cd复合污染土壤种植龙须草试验，以检测对龙须草光合作用的影响，检测龙须草对重金属复合污染的耐性，从而探讨龙须草修复重金属污染环境的能力。光合分析的结果表明：随着Pb、Cd复合污染含量的升高，龙须草的光合综合指标下降幅度较小，说明龙须草对重金属复合污染具有较强的耐性，且Cd对龙须草的影响大于Pb。

| Abstract: | Effects of combined pollution of cadmium(Cd)and lead(Pb)at nine levels on growth and physiology of Eulaliopsis binata were investigated.The aim was to estimate the tolerance to heavy metal pollution and furtherly test the abilities to restore the polluted environments.The results show that: At compounded pollution of Pb and Cd treatment,Ptoto-indexes were dropped slowly with increasing content of Cd and Pb,indicating that E.binata had strong abilities to endure stress of pollution.and the impact of Cd on E.... |
