摘　　要：涌流灌溉是一种节水型地面灌溉新技术。它是按一定时间间隔，周期性地分次而不是一次连续地向灌水沟畦供水以湿润土壤的灌水方法。涌流灌溉改变了传统的连续灌所存在的田间深层渗漏大，灌水不均和长畦（沟）灌水难的问题。这项技术是由美国于70代末研制的，随着涌流灌溉设备生产的系列化和商业化，已在美国西部得到迅速发展。我国于80年代中也开展了涌流灌溉技术的试验研究工作，并取得了一批成果，但还未能推广应用。Surge irrigation is a new kind of water saving technique for surface irrigation. It is a irrigation method that is used to irrgate soil at regular intervals periadically but not continuously. Surge irrigation helps to solve some difficult problems as large deep infiltration, ununiformity and difficult to irrigate for long border(or furrow). This technique has been developed in the Unite State in 1970s. It has been popularized in the western U. S. rapidly with the senation and commercialization of the surge irrigation equipment since 1980s it has been studied in China, and got some positive result,but has not been popularized yet.
