摘要
为调节土壤硒水平、开发利用富硒土地资源,预测和防止硒环境问题,以绥滨县农业土壤为研究对象,运用ArcGIS空间插值的分析方法研究绥滨县土壤全硒含量的区域分布特征,流经绥滨县的黑龙江水,松花江水以及地下水质量状况,并对富硒后水稻籽粒和蔬菜硒含量测定分析。结果表明：绥滨县土壤全硒平均含量为0.189mg·kg^-1,为足硒土壤。流经绥滨县的江水中含有丰富的营养元素,其微量元素各项指标好于地下水,微量元素总体含量水平为松花江水〉黑龙江水〉地下水。当地主栽品种水稻绥粳4号扬花期叶面富硒后水稻籽粒全硒平均含量为0.23mg·kg^-1,按国家食品中硒含量标准在0.1-0.3mg·kg^-1为安全含量。
In order to adjust the soil selenium levels of land resources, the development and utilization of the rich selenium,predict and prevent selenium environmental problems, the agricultural soils of Suibin county were studied. The regional distribution characteristics of total selenium content in soil, the quality of the Hei- longjiang river and Songhua river and groundwater in Suibin county were studied by using the analysis methods of ArcGIS spatial interpolation. The selenium content of rice grain and vegetable after Se - enriched was ana- lyzed. The results showed that the average content of total selenium in Suibin County was 0. 189 mg·kg^-1, which was enough for selenium. The nutrients of river water was rich, the indicators of the trace elements were better than groundwater, the total content of trace elements were the Songhua river〉 Heilongjiang river〉 groundwater. The average content of total selenium in paddy rice was 0.23 mg·kg^-1 after selenium enrichment in sowing stage of the main cultivar of rice （Suijing 4）. According to national standard of selenium content ,the content of selenium was 0.1-0.3 mg·kg^-1 as the safe content.
