| 摘 要： | 榆林北部风沙区水资源较为丰富，但浪费严重。6月中旬为该区气候稳定干旱期，7－8月为稳定湿润期，春小麦生育耗水与自然降雨供水错位，拔节到抽穗期为需水临界期，亦为灌水关键期，根据春小麦耗水量和水分供需平衡分析确定了榆林不同降水年份春小麦节水高产灌溉额。

| Abstract: | Water resources of the northern suburb of Yulin are abundant butwith a great waste,The stable dry season is in mid- July while the stable moisten season is in July and August.The water consumption of spring wheat fails to take advantage of the nature rain. The jointing stage and the heading stage are the critical period.Hence the amountof water- saving and efficient irrigation of spring wheat in different years in Yulin is determined by analyzing water consumption and water demand and supply balance of spring wheat. |

| Keywords: | water resource spring wheat water- saving and efficient irrigation. |
