摘　　要：In order to improve the utilization efficiency of heavy metal pollution of farmland,the revitalization of Hunan rice brand,this research worked on 20142016 oriented social extensive collection of 285 varieties of rice,including 98 early rice varieties and 187 late rice varieties.Screening and veri fication of rice varieties with low Cadmium accumulation were studied in Changsha-Zhuzhou-Xiangtan of Hunan Province,and in other typical cadmium polluted area in Hunan Province.12 early rice varieties and 13 late rice varieties were selected as low Cadmium accumulation varieties.Field test showed that,through the screening of varieties(V),irrigation(I)and acidity adjustment(P),the content of cadmium in early rice is 0.064~0.233 mg/kg,and 0.143~0.246 mg/kg in late rice,basically to ensure the content of cadmium in rice to reach the national standard,and to ensure good food security.为了提高重金属污染耕地的利用效率,振兴湘米品牌,20142016年面向社会广泛征集双季稻品种285个(早稻品种98个,晚稻品种187个),在湖南省重金属污染严重的长株潭区域,及省内其他典型镉污染区,进行了镉低积累水稻品种筛选及验证试验。共筛选出应急性镉低积累水稻品种25个,其中早稻品种12个,晚稻品种13个;大田验证试验表明,通过品种筛选(V)、水分管理(I)及酸度调整(P)等栽培技术,基本能够保证稻米镉含量(早稻:0.064~0.233 mg/kg,晚稻0.143~0.246 mg/kg)达到国家标准,保证粮食生产安全。
