摘　　要：根据河北平原三河井灌区节水灌溉工程推广应用的实践,提出了一种可称之为“支管退行式畦灌”的节水地面灌溉形式。这种灌溉形式属于畦灌,但可适用于畦长超过75m的长畦,畦长最长可达到200m以上,而且对地面平整度要求不高,同时又具有小畦灌的节水效果,在实现均匀灌水的情况下,可以达到750m3/hm2的灌水定额。According to practice of popularizing and applying water-saving irrigation technology in Sanhe well irrigation area in Hebei plain, this article puts forward a form of water-saving surface irrigation called ＂border irrigation by pipe move-back method＂. The form of irrigation is a kind of basin irrigation, but it applies to the long and narrow irrigation basins of more than 75 meters, which can cover beyond basin length of 200 meters and can be well performed without well leveled soil surface. It has effects of water-saving and uniform water depth in soil with the irrigation norm of 750 m^3 per hectare.
