半干旱半湿润气候区实施集雨节灌农业技术的研究

A Study on Agricultural Technology of Water Harvesting and Water-saving Irrigation in Semi-arid and Semi-humid Climatic Regions

在研究半干旱半湿润气候区集雨节灌农业理论依据的基础上,提出一整套集雨节灌农业技术体系,并对集雨节灌农业的效益进行了综合评估。在年降水量为300～800mm的地域推广集雨节灌农业技术具有普遍意义,尤其在年降水量400～700mm的地域其有效性最为显著。

Based on research on the agricultural technology of the water harvesting and the watersaving irrigation in the semiarid and semihumid climatic regions, a set of agricultural technologies was put forward The benefits of these technologies were evaluated. The application of these technologies was of universal significance in the regions with annual precipitation of 300～800mm, whereas the more significant benefits could obtain in the regions with annual precipitation of 400～700mm.
