| 摘 要： | 青海东部富Se土壤面积较大,其主要来源为古近—新近系西宁群红层物质,由湖盆退缩阶段稳定沉积形成,物质来源丰富且稳定。土壤中有效态Se含量水平较高,土壤总体上呈明显的碱性,有利于作物吸收利用。富Se土壤中有效态Se与全Se含量具有良好的相关性,并呈线性关系,有利于富Se产业的开发。

| Abstract: | There is a larger area of selenium-rich soil in eastern Qinghai, and it mainly origined from red layer material of Paleogene-Neogene Y;ning Group. Durinz the lake basin retrcated, the material steedily deposited and formed the soil characterized by abundant and stable material source. The soil held high lev- el of available selenium content and generally showed distinct alkalescence, which is propitious to absorp- tion and utilization for crops. In soil, the contents of available selenium and total selenium have good rela- tivity and showed linear relationship, making for the development of selenium industry. |
