针对山地丘陵地区的灌溉问题提出了因地制宜地将降雨集蓄与节水灌溉相结合 ,自压灌溉与机压灌溉相结合的观点 ,并按此观点设计了一个特点鲜明的集成系统。开发了有关技术 ,研制了相关设备 ,建立了相关设施 ,并将它们与已有的技术、设备、设施合理地结合起来以组成这一系统。试验表明该系统投资为 60 80 /hm2 元 ,年运行费用为 10 3 9.7/hm2 元 ,与传统种植相比 ,增产波菜 2 0 % ,效益费用比为 4.3 6。因而这一系统对于山区丘陵地区是适用的。研究还表明 ,山地雨水集蓄可减少水土流失与侵蚀 ,有利于水土保持 Aiming at the problem of irrigation in hilly area, this paper put forward the idea of ​​combining rainfall accumulation and water saving irrigation according to local conditions, combining pressure irrigation with mechanical pressure irrigation. According to this viewpoint, a unique integrated system was designed. Relevant technologies have been developed, related equipment developed, related facilities established, and they have been rationally combined with existing technologies, equipment and facilities to form the system. The experiment shows that the investment of this system is 6080 / hm2, and the annual running cost is 103.7 / hm2. Compared with the traditional planting, the system increases 20% of the wave dish and the cost-benefit ratio is 4.3 6. Thus this system is suitable for mountain hilly areas. The study also shows that rainwater harvesting in mountainous areas can reduce soil erosion and erosion, which is beneficial to soil and water conservation
