| 摘 要： | 为了解释高寒草地植物中矿物元素蓄积分异性发生机理，采用盆栽垂穗披碱草和青海冷地早熟禾等高寒草地植物，通过遮阴和增温等处理，试验样品的采集分析，结果表明：遮阴组和增温的对照组草地植物中矿物元素具有蓄积分异性，高寒草地植物体内矿物元素营养的蓄积增加是草地植物对生长环境变化的响应与适应，而生物矿物元素饥饿效应可能是生物矿物元素蓄积分异行为发生的内动力之一。

| Abstract: | To explain the mechanism of accumulation and differentiation of mineral elements in alpine grassland plants, cultivated alpine grassland plants such as Elymus nutans and Poa crymophila were treated with shading and warming, and then the samples were collected and analyzed. The results showed that the accumulation of mineral elements in the shading group and warming control group was significant difference, and the accumulation of mineral elements in the alpine grassland plants was response and adaptation to the growth environment. However, the “Starvation Effect” may be one of the endogenetic forces for accumulation and differentiation of biological mineral elements. |
