摘要
节水是一项重大国策,缺水的现状也决定了中国必须走节水型社会之路。农业用水目前占据了我国用水总量的55%,北方地区大量采用地下水井灌溉,通过二次提水来解决,灌溉用水成本较高,且影响生态,造成地下漏斗、沉降、海水倒侵等灾害。雨水作为自然来水,若有效利用可以控制及减少其他水源的使用,雨水的采集存储可以有效地补充农业用水。文章结合多年节水实践,建立了一套雨水与其他水源互为补充的自动化灌溉系统,以达到节水的目的;提出了备用水源补入节能模式,确保用电最小化设计;探讨了雨水与其他水源结合的灌溉控制技术;阐述了系统的应用方案及思考。
Water saving is a major national policy, China must also determine the current situation of water shortage of water-saving society. Agricultural water currently account for 55% of the total water in our country, the northern area of well irrigation, underground water is used by the secondary water, irrigation water cost is higher, and the influence of ecological, caused by underground funnel, subsidence, seawater invasion and other disasters. As natural rain water, if using can effectively control and reduce the use of other water, rainwater collection and storage can effectively supplement water. Combine water-saving practices for many years, this paper established a set of rain water and other water resources complement each other automated irrigation system, can achieve the purpose of water saving; Proposed the standby add water into energy saving mode, ensure minimum electricity design; Discusses the rainwater irrigation control technology, combining with other water expounds the application of the system scheme and thinking.
