摘　　要：通过8个籼稻品种在湘潭县A、B两处的早、晚稻种植试验,研究了其籽粒镉含量的积累特点。结果表明:不同品种、不同试验地间水稻籽粒的镉含量差异显著,早、晚稻间水稻籽粒的镉含量差异不显著;籽粒镉含量与各农艺经济性状的相关性不显著。The planting experiments of early rice and late rice was conducted in A location and B location of Xiangtan County for eight indica rice cultivars in order to study the accumulation characteristics of Cd in grain.The results showed that there were significant differences in Cd content in rice grain between different varieties and different experiment locations,but the difference in Cd content in rice grain between early rice and late rice was not significant;the correlation between Cd content in rice grain and each agricultural economic characteristics was not significant.
