摘要:

采用盆栽实验,研究油菜对铅、镉积累的生理特征和重金属对油菜的毒害作用的生理响应作用。结果表明:低水平镉、铅
复合处理对油菜的生物量、硝酸还原酶活性有促进作用,而高水平镉、铅复合处理则表现出抑制作用;油菜对镉、铅的吸收表现不同,镉在油菜中的转运系数高于铅的转运系数,表明油菜对镉的吸收效率较高。油菜可以作为修复镉、铅污染土壤的高生物量修复植物。

Abstract:

Pot experiment was conducted to study the tolerance and accumulation indexes of rape under different Pb and Cd
concentration. Low level of cadmium, lead compound on rape biomass, nitrate reductase activity and some catalytic play an active role, while high levels showed a inhibitory effect. Absorption of cadmium, lead in rape is different . Transfer coefficient of cadmium in rape is higher than that of lead. It shows that rape can be use of cadmium well. Studies have shown that rape can grow in the soils contaminated by cadmium and lead, get a high biomass ,and have strong absorptive capacity of cadmium. So it can serve as a kind of plant with repairing cadmium, lead contaminated soil.
