摘　　要：研究报道了青海高原主要粮食作物小麦、青课、蚕豆和豌豆中１８种矿质元素的背景值，并对其进行了综合分析。结果表明，青海高原地理范围广，各类粮食所有元素的含量变幅较大（几倍至几十倍）；不同种类粮食的大多数元素的含量差异极显著；同一作物不同品种之间元素含量无显著差异；粮食矿质元素的含量主要决定于作物生长的土壤环境。人体必需的微量营养元素铜、锌、铁和硒的含量偏低。In this paper,the background values of 18 mineral elements in wheat,high-land barley,broad bean and pea grown in Qinghai plateau have been analysed.The resultsshowed that the change of the mineral element content in the grains ranges from several todozen times due to the vast range.There are significant differences among different crops butthere isn't any significant differences among cultivars of the same crop.The mineral elementcontent of grains depends mainly on their growing soil environment.The contents of copper,zinc,iron and selenium which are necessary for human are lower.
