From June 10 to 18, 1977, the Chinese Academy of Sciences, the Ministry of Electricity and Water Supply and the First Machinery Division held a national exchange of experience in sprinkler irrigation technology in Tongliao County, Jilin Province. The conference organized live performances and indoor exhibitions on the prototypes sent to the meeting and carried out To observe and comment. Spray irrigation developed rapidly in recent years. As of June 15, 1977, the sprinkling area in 28 provinces, municipalities and autonomous regions nationwide reached 2.9 million mu, of which 37 were pilot projects of over 10,000 mu. There are 56,300 sprinklers installed, including 13,000 light-duty (3 to 5 horsepower), 38,000 small (10 to 12 horsepower), 4,000 to medium (24 to 28 horsepower), large (55 to 75 horsepower ) 470 units. During the conference, 58 irrigation sprinklers sent from 25 provinces, cities and autonomous regions conducted live performances. Over 40 irrigation equipment were exhibited at the exhibition hall
