Extension of water-saving irrigation technologies in 300 national key water-saving counties

Significant economic, social and ecological benefits were obtained by means of constructions of 300 national key water-saving countries during the period of the Ninth Five-Year Plan. The constructions promoted a nation-wide extension of water-saving technologies. This paper summarized 12 water-saving technologies used in the construction, including optimal deployment of water and land sources, optimal and unified uses of various water sources, efficient water conveying technology through pipes and canals, sprinkler and micro-irrigation technology, rainwater harvest technology, management technology and agronomic technology, etc.
