摘　　要：翻压绿肥在改善土壤理化性质,提高农作物产量的同时,也对土壤中Cd活性有直接或间接的影响。综述了绿肥作物对Cd污染耕地的治理效果,并从有机质、土壤p H值、土壤盐基阳离子、Fe活性等方面分析了绿肥对Cd活性影响的机理,据此提出通过种植、翻压绿肥治理Cd污染耕地的建议。The returning green manure can improve soil physical and chemical properties and increase crop yields, also have direct or indirect effects on Cd activity in soil. The improvement effect of returning green manure on Cd pollution was introduced in this paper. The remediation mechanism of green manure on the Cd activity was analyzed from the organic matter, p H value, soil base cations and Fe active etc in soil. Then some remediation suggestions were put forward by returning green manures in Cd pollution cultivated land.
