| 摘 要： | 以褐土为供试土壤,用小白菜作指示植物,通过模拟试验研究了土壤Pb,Zn复合污染对植物吸收重金属的影响。结果表明,在土壤Pb,Zn复合污染条件下,土壤中Pb的存在对蔬菜吸收Zn未产生明显影响,而土壤中Zn的存在则对蔬菜吸收Pb产生抑制作用。同时,分析复合污染条件下Pb,Zn在蔬菜体内的分布,表明小白菜主要将重金属Pb积累于根部,而Zn则是更多的被小白菜积累在地上部位。

| Abstract: | A simulated test of cinnamon soil jointly polluted by zinc and lead was carried out with non-heading Chinese cabbage as an indicator plant.The results indicated that Pb did not obviously affect the Zn absorbed by vegetable,while Zn inhibited Pb absorb by the plant.The absorbed Pb mainly accumulated in the underground part of the vegetable,while Zn mainly in the aboveground parts of non-heading Chinese cabbage. |
