Since Li Peng visited the Institute of Farmland Irrigation on June 15, 1990 and approved the issue of “Research and Demonstration of Water-saving Agricultural Technology System in North China” on July 15 of the same year, the Irrigation Department of Farmland quickly organized its forces and went deep into Henan, Shanxi and Hebei provinces and cities (counties) to carry out special investigations and studies, many times in consultation with the local government and business departments, but also with the Chinese Academy of Agricultural Sciences Soil and Fertilizer Institute, the crop and water conservancy department of science and technology personnel to conduct a joint test. Determined to establish three demonstration areas in Qingfeng County of Henan Province, Xiaxian County of Shanxi Province and Anci District of Langfang City of Hebei Province and set up four research topics. Namely “Research and Demonstration of Water-saving Agricultural Technology System in Qingfeng County, Henan Province”, “Research and Demonstration of Water-saving Agricultural Technology System in Xiaxian County, Shanxi Province”, “Research and Demonstration of Water-saving Agricultural Technology System in Langfang, Hebei Province” and " area
