| 摘 要： | 在干旱、半干旱地区，牧草因长期处于亏水环境中，形成了一定的抗性，存在一个较宽的对水分利用相对较高的生理耗水阈值。木文从这一水分生理角度出发，在充分研究牧草生理生态适旱系列变化过程的基础上，确定了几种干旱半干旱草地的经济耗水量，并制定出相应的经济灌溉制度。

| Abstract: | in arid and semi-arid Zones,herbage develops a certain resistivity to drought because of its growth in water deficient conditions for a long period of time. there is for it a greater threshold value of physiological water consumption which means a relatively higher efficiency of water use. Based on special studies on the evolution process of drought resistance of herbage from physiological and ecological aspects,the paper introduces the determination of several kinds of economical water consumption and recommends related economical irrigation regimes. |
