| 摘 要： | 通过采样和化学测试，对污水灌溉条件下，小麦、水稻、蚕豆和油菜果实中Cu、Zn、Pb、Cr和Cd的含量及土壤中重金属本底浓度进行测定和分析。结果表明，污水灌溉对4种作物吸收土壤重金属的能力影响不显著，而不同作物种类对这种吸收能力的影响表现出显著的差异。

| Abstract: | The content of Cu, Zn, Pb, Cr and Cd in wheat, paddy, horsebean and rape, and the background concentrations of heavy metals in soil were measured and analyzed through sampling and chemical test in this paper. The results indicated that sewage irrigation affected the adsorption capacity of plant for heavy metals unremarkable, while different plant type has remarkable influence on the adsorption capacity. |
