| 摘 要： | 本文通过实验室盆栽模拟试验,研究了磷肥对铅锌矿渣污染土壤中Zn、Cd、Pb、Cu等重金属的活性影响作用。结果表明:在铅锌矿渣污染土壤中施加不同比例的磷肥配比,对土壤中重金属活性影响很大,随着配比的逐渐升高,土壤中有效态重金属(Zn、Cd和Cu)含量呈现出升高-降低-升高的趋势,但Pb呈现出相反的变化趋势。

| Abstract: | Through the pot experiment,the influence of phosphorus on the activity of heavy metals in soils contaminated by Pb-Zn smelting slag were studied.The results showed that the amounts of phosphorus fertilizer added to pots have a significant impact on the activity of heavy metals in soils.The available Zn,Cd,and Cu contents showed the trend of increasing first,then decreasing,and increasing again with increasing phosphorus fertilizer addition,but the case is not true for Pb. |
