Abstract:Large sprinkler irrigation equipment also has some problems such as insufficient water vo-lume of single well, low intelligence of small and medium-sized sprinkler irrigation machines, low overall efficiency, poor adaptability to working conditions and insufficient serialization. The anti-blocking performance of micro-irrigation emitters under different water quality needs to be further streng-thened, and the accurate algorithm, practicability and reliability of intelligent decision-making of micro irrigation water and fertilizer integration system need to be improved. This new progress made in the research and development of sprinkler micro irrigation equipment in China since the 13th five year plan is summarized and focusing on the research and development progress of new products such as small and medium-sized sprinkler irrigation equipment, drip irrigation equipment and water fertilizer integration equipment. In view of the development trend of energy-saving, water-saving, inftelligent, regional modeling and standardization of irrigation equipment in China, the priority development directions of irrigation equipment are recommended. It mainly including: research on key technologies of energy saving and consumption reduction of irrigation equipment, agricultural irrigation equipment and technical model in hilly and mountainous areas, irrigation, drainage and salt control technology and equipment in saline alkali land, integration of water, fertilizer and medicine integration green prevention control technology equipment intelligent precision irrigation equipment, green multi-source complementary mode and unconventional water resource water-saving irrigation equipment.
