摘要
本文通过详细的野外地质及采样和室内分析化验工作，发现本区不同地区的农作物的含硒量是不同的，不少地区的玉米、茶叶、土豆、水稻等的含硒量在０．１—６．６ｐｐｍ范围内，是一般同类作物的含硒量（±０．０３６ｐｐｍ）［１］的３—２００倍；农作物的含硒量与基岩的含硒量、结构构造及地貌特征等密切相关。本文就紫阳县部分农作物的含硒量、作物的富硒规律、分布区域及开发利用前景进行了分析和讨论。
n the basis of detailed field work and laboratory analysis,it is found out that selenium contents in crops vary in different places of Ziyang County.Selenium contents in corn,tea,potato and rice in the county range from 0.1-6.6ppm which are 3-200 times that of the same crops grown in many places.Selenium conments in the crops of Ziyang are closely related with selenium content and texture of the bedrocks as well as landform characteristics.In this paper,selenium contents of the same crops in Ziyang,law of selenium enrichment in crops and their distributional districts as well as their development and utilization prospects are analyzed and discussed.
