| 摘 要： | 通过对乐都干旱山区实施集水高效农业气候学基础的分析,结合现有工作基础,重点讨论了集水区表面处理、蓄水窖建造及田间供水设施为主的雨水集蓄工程技术.以提高水资源利用率和水分生产效率为目的,进行集雨补灌试验研究.对地膜油籽、温棚蔬菜、马铃薯的有限补偿供应效应和农艺学节水技术进行研究,结果表明,在作物需水关键期进行补灌,可以达到水分供应的补偿或超补偿效应,提高作物水分利用率,促进旱区农业持续稳定发展.

| Abstract: | By analysis of climatology foundation data for implementing rainwater-harvesting efficiently agriculture, and the combinative current work foundation the rainwater-harvesting engineering techniques, such as managing surface of the catchment, constructing cellar of rainwater harvesting and facilities of water supplying, were discussed. The experiment of rainwater harvesting for improving water use efficiency was conducted. The limited compensation effect and saving water technique based on agronomic theory were studied on film-mulching rape, greenhouse vegetable, and potato. The results showed supplemental irrigation in key stage of crop requiring water could fulfill water supplying compensation or super-compensation effect and increase water use efficiency and the dry area agriculture could keep on the stability development. |
