摘要
通过对陇东旱原区实施集水农业气候学基础的分析，总结了以集水区表面处理、储水容器建造和田间供水设施为主的雨水集蓄工程技术，研究了集雨储水在地膜冬小麦、地膜春玉米、果树、塑料大棚蔬菜上的效果和农艺学节水技术，以及夏闲期塬面农田地膜覆盖集水保水效果。并对集雨节灌农业技术的运用效果进行了评价，提出了集水农业今后拟解决的几个理论和技术问题。
Based on the analysis of climatological bases of rainfall harvest and water saving irrigation farming in rainfed highland in the eastern Gansu, the techniques of lowering soil infiltration rates in catchment area surface, designing water storage work and device for lifting and conveying water from the tank to farmland were comprehensively reported. And the compensatory effects of limited stored water and agronomic measures for improving water use efficiency in film mulched winter wheat and spring corn, apple trees,vegetable growing in greenhouse, and the techniques fo field water harvest and soil moisture conservation were studied. Also the application of rainfall harvest and water saving irrigation techniques were evaluated. Then, the related technical and theoretical problems needing to be solved were put forward.
