摘要
通过对新疆天山北坡中部乌鲁木齐至沙湾地区平原绿洲带富硒土壤特征及生物效应进行分析研究,发现富硒土壤面积大、含量高、环境质量纯净、养分肥力质量优良、生物富硒效应好、农产品质量安全性高。富硒成因主要取决于当地典型河湖沉积相的表生地球化学环境,来源于由硒高背景地层经水流搬运而来形成的成土母质,有机质的吸附对表层土壤中硒元素富集起到关键性作用。同时对国内富硒食品含量标准进行对比,为新疆富硒食品含量标准提供推荐建议。发现的名优特产富硒食品主要有葡萄、辣椒、小麦和番茄,建议进行重点开发利用。
Through analysis and study on the characteristics and biology effect of selenium-rich soil in the plain oasis of Urumqi to Shawan area in the middle of north slope of Tianshan Mountains in Xinjiang,a large area of selenium-rich soil have been discovered,and the selenium content is higher,the soil environmental quality,the soil fertility quality,the biology effect of selenium-rich,the crop safety quality of selenium-rich soil all are better,the causes of selenium-rich depends on the supergene geochemical circumstance of local fluvio-lacustrine deposits,and selenium mainly came from the soil parent materials while formed the high background formation by flowing water,and the adsorption of organic matter played a key role in the enrichment of selenium in the surface soil.and,basing on contrasted the content standards of selenium-rich foods in china,we can provide some recommendations for formulating the content standard of selenium-rich foods in Xinjiang.The famous brand products of selenium-rich while have been found include grape,pepper,wheat and tomato,we recommends focusing on the development and utilization.
