Taquupo Reservoir in Shaanxi Province is located in the northern part of Weibei Plateau Yao County, mainly to irrigation, both flood control, fish farming benefits. Design irrigation area 289000 mus. The shortage of water and water resources is the actual problem of irrigation management. In order to save water and increase production and enhance the development potential of agriculture, the Spring Reservoir Management Bureau in 1986 planned the implementation of “demonstration farmland of 10,000 mu of high yield under high-rise trees” (hereinafter referred to as Fangtian).
