摘　　要：为达到污染耕地的旱粮安全生产,筛选出适合浙江地区种植的重金属低积累旱粮品种,通过田间试验,在重金属复合污染耕地种植旱粮作物高粱、玉米和大豆各10个品种,分析旱粮籽粒中镉(Cd)、镍(Ni)、铜(Cu)和锌(Zn)等重金属元素含量。结果表明,高粱Cd低积累品种优选晋糯3号,玉米品种Cd低积累品种优选浙糯玉86和浙甜19,大豆Cd低积累品种优选浙春8号;具有同时低积累Cd、Ni、Cu和Zn特征的高粱品种为晋糯3号和晋杂31号,玉米品种为浙糯玉18、浙糯玉86和银糯1号,大豆品种为浙春8号和辽鲜。本研究结果可为浙江地区污染耕地安全利用过程中重金属低积累旱粮品种的选择提供科学依据。In order to screen optimum varieties of dry grain crops with low accumulation of heavy metals in polluted farmland,we planted 10 varieties each of drought-tolerant crops,such as sorghum,maize,and soybean on farmland contaminated with heavy metal compounds,and analyzed the contents of heavy metal elements such as Cd,Ni,Cu,and Zn in the grains of these crops by conducting field experiments.The results showed that the preferred sorghum variety with low Cd accumulation was Jinnuo 3,the preferred maize varieties with low Cd accumulation are Zhenuoyu 86 and Zhetian 19,and the preferred soybean variety with low Cd accumulation was Zhechun 8.Sorghum varieties with low accumulation of Cd,Ni,Cu,and Zn were Jinnuo 3 and Jinza 31,maize varieties with low accumulation of Cd,Ni,Cu,and Zn were Zhenuoyu 18,Zhenuoyu 86,and Yinnuo 1,and soybean varieties with low accumulation of Cd,Ni,Cu,and Zn were Zhechun 8 and Liaoxian.The results of this study can provide a scientific basis for selecting dry grain crop varieties with low accumulation of heavy metals in polluted farmland in the Zhejiang region.
