摘　　要：为了解释高寒草地植物中矿物元素的蓄积性,以盆栽垂穗披碱草中定期喷施矿物元素液体混合肥为试验,并进行样品采集与分析检测。结果表明:喷施矿物元素液体混合肥,能有效增加盆栽垂穗披碱草中所施的各种矿物元素营养(P<0.05),而使盆栽土壤中矿物元素含量降低较小(P<0.05),即定期喷施矿物元素液体混合肥的盆栽垂穗披碱草,由于饥饿效应而使相应矿物元素营养蓄积增加,也就是说饥饿效应是驱使矿物元素营养蓄积增加的内动力之一。In order to explain the accumulation characteristic of mineral elements in alpine meadow plants, test to potted Elymus nutans treated with regularly spraying liquid mix fertilizers of mineral elements, and the sam- ples were collected and analyzed.The results show that effectively increased the mineral elements contends in potted Elymus nutans （P 〈0.05）, and decreased the mineral elements contend in soil under spraying liquid mixed fertilizers of mineral elements（P〈0.05）.The accumulation of mineral elements nutrition was due to the ＂Starvation Effect＂ , and the Starvation Effect was one of the endogenetic forces for accumulation increased of mineral elements.
