连云港市郊区稻田土壤与水稻重金属镉含量分析

摘要

以取自连云港市郊区的24个水稻样品和24个对应土壤样品为研究对象，分析重金属元素镉的含量。结果表明：连云港市郊区稻田土壤重金属镉含量未见明显不同；水稻不同器官镉含量分布规律是根＞茎叶＞稻壳＞糙米；生育期短的水稻品种植株中镉含量高于生育期长的品种。%24 rice samples and 24 corresponding soil samples which were obtained from the suburbs of Lianyungang City were used to analyze cadmium content. The results showed that the cadmium content had no obvious difference among the paddy soil samples of suburb in Lianyungang City, the distribution law of different organs of cadmium content of rice was：root〉stem leaf〉rice husk〉brown rice, the cadmium content of the rice with short growth period was higher than the rice with long growth period.
