干旱半干旱地区的果树生产大多只能依靠自然降水，在常规管理条件下，自然降水量远远不能满足果树正常生长发育的需求，严重地影响了果树生产的发展和经济效益的提高，为解决这一生产难题，我们进行了该项研究，通过调节自然降水的时空分布，提高了果树栽植成活率，开始结...
Most of the fruit trees in arid and semi-arid areas can only rely on natural precipitation. Under the normal management conditions, the natural precipitation can not meet the demand of normal growth and development of fruit trees, which seriously affects the development of fruit trees and the improvement of economic benefits. This production problem, we conducted the study, by adjusting the temporal and spatial distribution of natural precipitation, improve the survival rate of fruit trees planted, began to knot ...
