[摘要] 针对示范区地形开阔、土地资源丰富、宜于统一管理等条件,通过对国内外节水技术和设备的考察,引进自动化程度较高的美国圆型喷灌机,建设喷灌节水示范区。通过对示范区圆型喷灌机与地面传统灌溉方式对比监测和田间试验研究,分析计算节水示范区工程建设投资费用、年运行费用和效益,并进行综合评价。结果表明:与地面传统灌溉方式对比,采用圆形喷灌机灌溉可以减少劳动强度,提高工作效率,增加作物种植收益,产生了显著的经济、社会、生态效益。

Abstract: The saving water model district, irrigated by center pivot sprinkler machine made in USA which has high automation, has been to the saving water model district engineering construction investment expenses, the year operating cost and the benefit carries on putation, and analyzes its social economy benefit. Demonstration area on the ground round irrigation machine pare the traditional irrigation methods and field experiments to monitor testing, construction of water-saving demonstration zone investment cost, annual operating costs and reasonable analysis and evaluation of result indicated: With the ground tradition irrigation way contrast, uses the circular to spurt irrigates the technology to be possible to reduce the labor intensity, enhances the crops planter e, has the remarkable economy, the society,
