陕西省永寿县地处渭北旱腰带西缘,海拔572.1~1 505.3 m,年均降雨量600 mm左右,是典型的雨养旱作农业县,干旱始终是制约永寿农业生产的主要因素。目前,国内关于抗旱节水增效的途径较多,但大多数操作性不强,且成本较高。永寿县自2009年实施小麦高产创建项目以来,紧紧依托小麦高产创建项目的实施,不断加大小麦旱作节水技术试验示范力度。尤其是2012年秋播后的10月至2013年5月,永寿县
Yongshou County, Shaanxi Province is located in the western margin of Weibei drought belt, with an elevation of 572.1-1 505.3 m and annual average rainfall of about 600 mm. It is a typical agricultural county for rain and drought relief. Drought has always been the main factor restricting Yongshou’s agricultural production. At present, there are many ways to combat drought and water conservation and synergies in China, but most of them are not easy to operate and cost more. Since implementing the project of high-yielding wheat in 2009, Yongshou County has been relying on the implementation of the project of high-yield wheat and continuously increasing the experiment and demonstration of water-saving technology for dry farming of wheat. Especially in the autumn of 2012 after the broadcast from October to May 2013, Yongshou County
