无产阶级文化大革命以来,在各地广泛开展的群众性科学实验运动的基础上,喷灌作为农业增产、省水的一项有效措施,已逐渐被人们所认识和重视。当前,在全党动员、大办农业、为普及大寨县而奋斗的伟大革命运动推动下,喷灌技术又有新的发展。机具不断完善,水平不断提高;各地试点面积不断扩大,千亩、万亩的大面积试点相继出现;不少省、市已经把发展喷灌列入议事日程。喷灌正由试验研究迈入大面积生产使用的新阶段。为适应这种发展的趋势,必须切实抓好喷灌系统技术经济指标的分析。
Since the Great Proletarian Cultural Revolution, sprinkling irrigation as an effective measure to increase agricultural output and save water has gradually been recognized and valued by people on the basis of extensive mass scientific experiments carried out in various places. At present, under the impetus of the great revolutionary movement, mobilized by the entire party, majoring in agriculture and fighting for the popularization of Dazhai County, there is another new development in sprinkler irrigation technology. Continuous improvement of equipment, continuously improve the level; around the pilot area continues to expand, acres, acres of large-scale pilot have appeared; many provinces and municipalities have been included in the development of sprinkler irrigation schedule. Sprinkler irrigation is entering a new phase of large-scale production and use by experimental research. In order to adapt to this trend of development, we must earnestly grasp the sprinkler system technical and economic indicators.
