中文摘要	研究了辽西半干旱区井灌条件下褐土涌流畦灌的节水效果.结果表明,与传统的连续灌方式相比,涌流畦灌节水率可达21%～35%,灌水有效率、储水效率和灌溉均匀度分别提高5.3%～7.2%,6.3%～7.8%和18.8%～24.9%.涌流畦灌的平均水流速度提高了30%～80%,最大灌水长度增加了22%～37%.在一定范围内,适当缩短周期灌水时间,增加灌水周期数会提高涌流畦灌的节水率.涌流畦灌的周期数依畦田长度而定,畦长短于200m以2～3个周期为宜,畦长200～400m则以3～4个周期为宜.
英文摘要	Water saving effects on surge flow border irrigation were studied under well irrigation in semi - arid area of West Liaoning. The results showed the rate of available water,might be saving reached 21% -35% ,the rate of water saving,the rate of water storage and the uniformity of water application increased 5.3% -7.2%, 6.3% -7.8% and 18.8% -24.9%, respectively, compared surge flow border irrigation to continuous irrigation. The average velocity of surge flow border irrigation increased 30% - 80% and the longest length of irri-gation increased 22% ~ 37%. Within a certain range, the rate of water saving might be improved by adding number of irrigation cycles and shortening the period of irrigation cycle. The cycle numbers of surge flow border irrigation were determined according to the length of border. In general, cycles of 2 -3 suite to the border length <200m and of 3 -4 to the length in 300 ~400m.
