Abstract: Effect test of field sprinkler irrigation was carried out in Doudian town of Fangshan district and Henanzhai town of Miyun district by taking semi fixed sprinkler irrigation equipment and circular sprinkler that commonly used in Beijing as research object.Application effect of semi fixed sprinkler irrigation equipment and circular sprinkler was analyzed from quality of irrigation equipment，irrigation intensity，uniformity of irrigation，and soil moisture changes before and after irrigation etc.Results showed that uniformity of sprinkler irrigation of semi fixed sprinkler irrigation equipment was 86.8%.Uniformity of sprinkler irrigation of circular sprinkler was 92.3%.Compared with traditional pipe irrigation，amount of water saved was 1 514.55 m3/hm2 and 1 771.2 m3/hm2 by applying semi fixed sprinkler irrigation equipment and circular sprinkler during winter wheat irrigation.Water saving rate was reached 31.71% and 34.88%.In terms of production，test results showed that wheat yield increased by 0.45% and 2.99% through the use of semi fixed sprinkler irrigation equipment and circular sprinkler.At the same time，application scale mathematical model of sprinkler irrigation equipment was established combined with application cost and water saving effect of equipment.Results showed that the use of circular sprinkler was more efficient when area of continuous irrigation was more than 22.08 hm2.Experimental results provided theoretical basis and equipment support for further extension of water saving irrigation technology in Beijing city.
