| Abstract: |
| Basing on analysis of the situation of water resources in Loess plateau areas, this paper propounded the engineering and agricultural technology and the method with direct and indirect, which draw rainwater on road surface into “soil reservoir” of farmland or water cellar with free atmospheric pressure using silt delve of eliminate energy. Experiment and practice in Dingxi areas of Gansu province show that this method and technology could not only enhance precipitation utilize efficiency but be simple and easy to carry out, thus is an efficient way of agriculture rainwater use in Loess Plateau areas, meanwhile this technology has effect on preventing soil and water erosion and improving agricultural ecology in the area. |
