Abstract Water-saving irrigation equipment plays an important role in improving agricultural water use efficiency, increase farmer income and construction of ecological environment, also it has an important strategic position to ease the shortage in water resources, ensure the national food security, and promote the sustainable development of rural economy. The development of water-saving irrigation equipment has taken nearly for 60 years, a considerable progress has been made in its theoretical study and technical level and so on; further the scale of production can basically meet the development of water-saving irrigation in China, but the ability in technological innovation, research and development is weaker, the improvements in product quality, technical performance and reliability are on demand. The developing trends in water-saving irrigation equipment should include strengthening basic theoretical study, enhancing the capability of independent innovation, designing and manufacturing intelligent, precise, cheap and green water-saving irrigation equipment with multi-function, low energy consumption and cost. It is suggested that the comprehensive technology and equipment for water-saving irrigation in hilly land should be investigated. The multi-function, intelligent and precise sprinkler irrigation systems should be developed. Also, the irrigation technology and equipment with low cost, high efficiency and collaborative precision in water and pesticide spraying as well as fertilizing should be innovated. The water-saving irrigation technology and equipment by using clean energy should be exploited. These suggestions may promote the water-saving irrigation equipment industry to develop in a comprehensive and healthy manner in China.
