摘　　要：利用高富集植物吸收重金属的特性,将重金属高富集植物和农作物间作,降低农作物对重金属的吸收,达到一边修复一边耕作的目的,提高土壤的利用率.于是将大豆与番茄、玉米与番茄分别间作的方式处理重金属Cd污染土壤,同时将大豆、玉米和番茄分别单种作为对照组.分析间种、单种对土壤Cd的不同富集率.研究结果表明:大豆、玉米和番茄分别单作时,番茄对Cd的富集效率最高,达到3.80 mg/kg,Cd的去除率最高达到92.49%.而在番茄与大豆、番茄与玉米间作时,大豆与番茄对Cd的富集效率高,达到20.98 mg/kg.Cd的去除率最高达到92.91%.The characteristics of enrichment plant uptake of heavy metals,high heavy metal enrichment plants and crops as,reduce the absorption of heavy metals in crops,achieve the goal of while restoration while farming,improve the utilization rate of soil. In this paper,the Cd contaminated soil was treated by soybean and tomato,corn and tomato,and the control group was treated with soybean,corn and tomato. Analysis of single tree and intercropping,the Cd of different concentration rate in the soil. The results of the study show that：soybean,corn and tomato were monoculture,tomato of Cd enrichment efficiency reached the highest 3. 80 mg / kg,Cd of the removal rate reaches the highest 92. 49%. While in tomato and soybean,tomato and corn intercropping,the enrichment efficiency of soybean and tomato on Cd was high,reached 20. 98 mg / kg. The removal rate of Cd reached 92. 91%.
