摘要
针对目前我国水资源紧缺,灌溉效率低的现状,提出了新型的既节水又节能的负压给水技术。对负压给水技术的研究背景、系统组成、工作特性、产生过程以及系统的维持方法进行了详尽的介绍,以期为现代化灌溉发展提供新的思路。
Based on the current lack of water resources and inefficient irrigation , a new negative pressure water supply technology of water-saving and energy-saving is proposed. In this paper, the research background of negative pressure water supply technology, system composition, work characteristic, production process and system maintenance method are introduced in detail in order to provide new ideas for agricultural development.
