Discussion on the Water-Saving Technical System in the Yellow River Irrigated District in Ningxia

The irrigation district of Yellow River in Ningxia had been in the habit of over irrigation and over drain,which caused bad results such as low water use efficiency,soil salinization and deterioration of water environment.Based on analyzing the status quo and existing problems of the water-saving irrigation practices in the Yellow River irrigation district in Ningxia,this paper proposed a comprehensive water-saving technical system suitable to the locality,namely as rational development and use of water resources,water-saving irrigation engineering,water-saving techniques in farming along with water-saving management.Meanwhile we farther put forward the integration and demonstration of modern water-saving and agricultural technologies that should be the key research points in accordance with the developing object of water-saving irrigation in the Yellow River irrigation district in Ningxia.
