我省一九七五年开始发展喷灌,截至一九七九年十一月三十日止,全省累计喷灌面积达到八十五万余亩(其中固定式一千五百亩,半固定式一千亩,自压喷灌六万余亩)。一九七九年新增加七十一万余亩,去冬抗旱喷麦九十余万亩,收到显著的效益。为了掌握我省喷灌发展的情况、经验和存在问题,我们对南阳、许昌、驻马店、洛阳、开封、新乡和郑州市、洛阳市八个地、市,二十五个县进行了概略地调查,现对我省发展喷灌中值得研究的几
In 1975, the province started to develop sprinkler irrigation. As of November 30, 1979, the total sprinkler irrigation area in the province has reached 850,000 mu (of which the fixed type is 1,500 mu and the semi-fixed type One thousand acres, self-pressure irrigation more than 60,000 acres). In 1979, a total of more than 710,000 acres were newly added to fight drought and more than 90,000 mu of wheat were harvested in the winter and received significant benefits. In order to grasp the situation, experience and existing problems of sprinkler irrigation in our province, we conducted a survey on eight prefectures, cities and twenty-five counties in Nanyang, Xuchang, Zhumadian, Luoyang, Kaifeng, Xinxiang and Zhengzhou and Luoyang, Now the development of irrigation in our province worth a few studies
