| 摘 要： | 研究了Pb^2 在土壤和改性土壤中的吸附特性；并通过盆栽实验，研究了在添加钝化剂条件下，添加外源Pb^2 对油菜生长性状的影响和Pb^2 在土壤－油菜系统中吸持、迁移和积累的特性。结果表明；Pb^2 对油菜生长具有刺激促进作用，Pb^2 在油菜体内不同部位的分配规律为根＞茎叶。纯化剂对Pb^2 具有良好的吸附钝化作用，可有效地抑制P b^2 在油菜体内的积累。

| Abstract: | Kinetic characteristics of lead adsorption in soil-water systems were discussed. Furthermore, effect of Pb pollution on cole growth and its adsorption, migration and accumulation in soil-cole systems under soil modifying measures were studied with pot experiment. The results showed that the transport of lead in the soil-water systems was a fast process. The adsorption of lead by cole was in order of root>stem and leaf. The application of modifier could effectively restrain the accumulation of lead ions in cole. |
