As global climate change and water resource shortages intensify,improving the efficiency of agricultural water use has become a major global focus.This paper reviewed the development and application of water-saving irrigation technologies,such as drip irrigation,sprinkler irrigation,micro-sprinkler irrigation and subsurface drip irrigation.The principles,advantages,disadvantages and applicability of these technologies were analyzed.Case studies on water-saving irrigation for dryland wheat in Fuping County,high-efficiency water-saving irrigation in Shanghai and the application case of the Guishi irrigation district in Hezhou City further validated the comprehensive benefits of water-saving irrigation technology.Finally,the paper proposed future development directions for water-saving irrigation technologies,emphasizing the importance of intelligent irrigation systems and the application of new materials,and the necessity of policy support and technology promotion.
