摘要
微喷带田间的布置方式直接影响了其灌溉工程的投入和工程效益的发挥,本文以多年工程实践为基础,对移动式、半固定式及固定式微喷带灌溉系统适用条件进行了探讨。结果发现:移动式微喷带灌溉系统简单易用,但运行成本高,适合小地块灌溉;固定式微喷带灌溉系统一次性投入高,但方便管理,运行成本低,适合规模化节水灌溉工程;半固定式微喷带灌溉系统工程成本和运行成本介于上述两者之间,适合中等面积地块的灌溉。
The layout of micro-spraying hose directly affects the investment of irrigation project and the development of engineering benefit.Based on years of engineering practice,the application conditions of mobile,semi fixed and fixed type micro-spraying hose irrigation systems are discussed in this paper.The results show：the mobile micro-spraying hose irrigation system is simple and easy to use,but high operating cost,suitable for small plot irrigation.The fixed micro-spraying hose irrigation system has a high investment,but it is convenient for management,low operating cost and suitable for large-scale water saving irrigation project.The engineering and operating cost of the semi fixed micro-spraying hose irrigation system are between the above two,which is suitable for irrigation in medium area.
