摘要
为了满足人们对健康的追求,研究从宁夏稻米种植区土壤中微量元素硒含量的本底状况及含量评价展开。以宁夏回族自治区粮食作物耕作区的基本农田为调查采样的目标区域,通过原子分光光度法对土壤中微量元素硒进行检测分析,比较了全土壤中平均含量、不同行政区土壤以及不同土壤类型中微量元素硒含量的差别。结果表明:所采集的土壤样品中,不同行政区土壤样品中硒含量差别不大,而不同土壤类型中硒含量有差别且西部土壤含硒量较高,其中局部地区达到中硒土壤上限。
In order to satisfy customers for health, this paper evaluated the trace element selenium background distribution of major grain cultivation（rice） area in Ningxia, the study collected soil from basic farmland soil in Ningxia. The content of trace element selenium in soil were detected and analysed through atomic spectrophotometry. At the same time, the content of trace element selenium of total soil, soil from different administrative region and soil of different geomorphic units were compared and analysed the differences. The result showed that the content of trace element selenium have no differences in soil from different administrative region and there was differences in soil of different geomorphic units and the content of selenium is higher in western region.
