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 meet the people’s pursuit of health, the paper studied the background and content of trace element selenium in soils from rice planting areas in Ningxia. Taking the basic farmland of grain crop cultivation area in Ningxia Hui Autonomous Region as the sampling target area, the content of trace element selenium in soil was detected and analyzed by atomic spectrophotometry. The average content of total soil, the content of soil in different administrative areas, Differences in elemental selenium content. The results showed that there was no significant difference in the selenium content of soil samples collected from different administrative regions, but the content of selenium in different soil types was different and the content of selenium in the western soil was higher, and the upper limit of medium and selenium soil was reached in some areas.
