| 摘 要： | 通过盆栽试验,采用单因子污染指数和内梅罗综合污染指数法进行评价,分析了磷石膏及其施入土壤后土壤重金属(Cd、Hg、Pb、Cr、As)污染指数的变化。试验结果表明:在磷石膏较低施量水平下,大豆生物产量与籽粒产量较高。磷石膏符合《农用污泥污染物控制标准》GB4248-84,施用不会引起土壤重金属的污染,连续多年施用应按照安全施用年限确定合理施用量。施磷石膏3000kghm-2大豆籽粒各指标处于优良范围内,而秸秆分别受到Cd、Hg的轻度污染和重度污染。施磷石膏12000kghm-2大豆籽粒受到Cd的轻度污染,秸秆分别受到Cd、As的轻度污染,Hg的重度污染,大豆秸秆富集重金属的能力强于籽粒,综合比较1500～3000kghm-2为安全施用水平。

| Abstract: | Through the pot experiment,the single factor index method and N.L.Nemerow synthesized index number method were adopted to evaluate and analyze the variations of heavy metals(Cd,Hg,Pb,Cr,As) pollution index by the application of phosphogypsum into soil.The results indicated that biological production and grain yield of soybean were relatively high in the low level of Phosphogypsum application.The experimentation suggested that Phosphogypsum was in accordance with the Standard of Pollutant Release from Sewage... |
