| Abstract: | Yearly average rainfall is 35O~45Omm in Loess Plateau.Drought is a importantfactor to limit crop production in slope land.The local farmer already summarized a set of culturalmethods of rain use and saving water irrigation,which protected land resources effectively andincreased water resource use rate.The summarization on technologic characters,conditions,benefits,and utilizing foreground might accelerate water resources use and construction ofecological agriculture. |
