牧草节水灌溉若干理论问题研究

Study on some theoretical problems in water saving irrigation of forage grass

牧草长期在亏水环境中生长，形成一定的抗性．本文从这一水分生理角度出发，在研究牧草适旱生理生态演化和干旱半干旱草地牧草的经济耗水量的基础上。

Based on the study on the evolution process of drought resistance of herbage,from view points of physiological and ecological aspects,and the economical water consumption of herbage in arid/semi arid area,this paper proposed the method for optimal decision making of water saving regimes.
