Irrigation types
中国现有常用节水灌溉方法包括渠道防渗、喷灌、微喷灌、渗灌和滴灌等，均为人为控制灌溉时机和灌水量，属于“被动式”灌溉模式。以色列滴灌技术被公认为目前效果最好的节水灌溉技术，中国自上世纪70年代末引进以来，取得了长足发展。但是滴灌灌水器为了实现更小流量的灌水以及长距离铺设，就必须不断地减小流道尺寸，由此带来了流道易堵塞及制造难的问题。
The existing water-saving irrigation methods in China include canal seepage control, sprinkler irrigation, micro-sprinkler irrigation, seepage irrigation and drip irrigation. They are all artificial control of irrigation www.jinggaimoju.net.cn www.hupomoju.com.cn www.biaozhizhuang.net.cn www.jianchajing.org.cn www.shipindai.net.cn timing and amount, and belong to the "passive" irrigation mode. Drip irrigation technology in Israel is recognized as the best water-saving irrigation technology at present. China has made great progress since it was introduced in the late 1970s. However, in order to achieve a smaller flow rate of irrigation and long-distance laying, drip irrigator must constantly reduce the size of the runner, which brings the problems of easy blockage and difficult manufacture of the runner.
