摘　　要：我国农田土壤中Cd污染问题突出,其修复技术一直备受关注。基于超积累植物的植物提取技术是根治我国Cd污染农田土壤的热门修复技术,但单一的植物提取技术模式通常无法保障污染地区正常的农耕生产需求,故当地农户对该技术的接受程度普遍较低。为解决单一超积累植物修复技术在工程应用推广中的实际问题,提出“高效修复与安全生产”相结合的双赢策略,总结了前人对植物修复技术、超积累植物的概念由来及研究范围,综述了现阶段基于超积累植物的间、套、轮作修复模式的研究进展,统计比对了各种植物组合耕作模式对Cd污染农田土壤的综合治理效果,并对今后利用不同种植模式修复Cd污染农田土壤提出了研究展望。The severity of heavy metal pollution in soil has increased the awareness of remediation methods.The technology of plant extraction is a focal point in the field of agriculture;however,a single plant extraction technology model is often unable to guarantee meeting the agricultural production demand of people in a polluted area.Therefore,the acceptance of this technology by local farmers is generally low.To solve the practical problems in the application and popularization of single hyperaccumulation phytoremediation technology in engineering,in this study,we present an effective strategy of“efficient phytoremediation and safe production.”Furthermore,we summarized the concept origin and research scope of previous phytoremediation technology and hyperaccumulator plants;summarized the research progress of intercropping,interplanting,and crop rotation phytoremediation model based on the hyperaccumulator plants;and performed a statistical comparison.The effects of various plant cultivation modes on the comprehensive treatment of cadmium polluted farmland soil are discussed,and the research prospect of using different cultivation modes to repair cadmium polluted farmland soil in the future is proposed.
