本研究针对以往在干旱地区建设蓄水窖造价高、费工费时和旱地冬小麦生长期存在的各种逆境及有限补灌时期和补灌定额的诸多问题,从蓄水窖位置的选择,蓄水窖容量的确定,根据地形确定蓄水窖的形状,窖壁处理技术等方面开展了修建蓄水窖工艺技术和有限补灌农艺节水的系列研究,为不同旱作类型区的小麦高产高效提供技术支撑。
In this paper, aiming at the problems such as high cost, time-consuming and labor-intensive construction of water storage cellar and various adversities of limited irrigation period and supplementary irrigation quota in dryland winter wheat growing season in arid areas, from the choice of storage cellar location, Based on the terrain to determine the shape of the water storage cellar and the treatment of the cellar wall, a series of researches on the technology of water storage cellar and limited water supplement for agronomy were carried out to provide the high-yield and high-efficiency wheat for different types of dry farming Technical Support.
