1 Water-saving irrigation status and existing problems 1.1 Current status of water-saving irrigation Weishi County is located in the eastern Henan Plain, most of the area is located in the middle and lower reaches of the Yellow River irrigated irrigation area. The main supporting facilities for dry and branch channels are all soil ditches, which are mostly sandy loam areas due to the channels, and the seepage channels of the channels are mostly serious. The bucket ditches of the field works are partly matched, but all are soil ditches and are not hardened. The seepage is also very serious Serious; farmland is not flat land, 畦 Tian non-standard, the basic flood irrigation. However, water saving irrigation in Weishi County has also made some progress, and in some areas, low-pressure pipeline water conveyance, sprinkler irrigation and ground hose irrigation have been adopted
