安徽农学通报2023年02期粮食·油料·经作基于镉元素的重金属低积累水稻品种筛选吴支行1夏敏2*叶寅2杨欣2袁自然2（1芜湖市农业技术中心，安徽芜湖241000；2安徽省农业科学院土壤肥料研究所，安徽合肥230031）摘要为筛选适合镉污染耕地种植的镉低积累水稻品种，促进水稻绿色生产，以芜湖市种植较为普遍的13个水稻品种作为试验对象，进行田间小区试验，测定其在芜湖市某试验点的农艺性状和糙米镉含量。试验结果表明，武运粳31号表现出的农艺性状较为优异，徽两优114号和亚两优丝苗表现出的镉低积累特征较为优异。因此，对于镉低积累水稻品种的推广应用应综合考虑区域土壤实际镉浓度和经济效益选择合适的水稻品种。关键词镉低积累；水稻；品种筛选；糙米镉含量；农艺性状中图分类号X173；S511文献标识码A文章编号1007-7731（2023）02-0039-04ScreeningofRiceVarietieswithLowAccumulationofHeavyMetalsBasedonCadmiumElementWUZhihang1XIAMin2*YEYin2YANGXin2YUANZiran2（1WuhuAgriculturalTechnologyCenter,WuhuAnhui241000;2SoilFertilizerResearchInstitute,AnhuiAcademyofAgriculturalSciences,HefeiAnhui230031）AbstractInordertoscreenlow-cadmium-accumulatingricevarietiessuitableforplanting,13ricevarietiescommonlyplantedinWuhucitywereusedasexperimentalobjects,andafieldplotexperimentwascarriedout.Andtheiragronomictraitsandcadmiumcontentinbrownriceweredeterminedattheexperimentalsites.ThetestresultsshowedthatWuyunjing31showedbetteragronomicstatus,andHuiliangyou114andYaliangyousilkseedlingsshowedbettercharacteristicsoflowcadmiumaccumulation.Therefore,thepromotionandapplicationinthewholeregionshouldcomprehensivelyconsidertheactualcadmiumconcentrationinthesoilandtheeconomiceffecttoselectsuitablericevarieties.Keywordslowcadmiumaccumulation;rice;selectionofvarieties;cadmiumcontentinpolishedrice;agronomictraits根据调查，我国受重金属污染耕地面积约有2000万hm2，其中镉是无机污染物中超标量最多的重金属污染物之一，占无机污染物超标量的7%[1]。与其他重金属相比，镉具有分解周期长、移动性大、毒性高、降解难、易被作物吸收等特点[2]。目前农产品镉超标是我国农业土壤镉超标问题的主要体现，这些镉超标的农产品一旦流入市场，进入人体，经体内分布代谢转化，会造成人体多器官损伤[3-4]。...
