摘　　要： 通过３年（１９９２～１９９４年）试验研究表明，河西绿洲灌区，在水分限制条件下，春小麦、春玉米、马铃薯、油菜和胡麻６种作物存在着节水高产高效的现实性和可能性，同时水肥之间具有明显的耦合效应。就肥料效应而言，春小麦、春玉米、油菜在高灌条件下增加肥料用量，仍有利可图。马铃薯和胡麻适当限制施肥量，在高效方面具有一定的积极意义。 The results of 3 years'experiment(1992～1994)showed that:it was possible to achieve high yield and profit for Spring wheat, Spring corn, Potato,Spring rape and flax while water supply was limited in the irrigation area of Hexi oasis,and there were obvious correlation between water and fertilizer amount.Increasing fertilizer applicatoin to Spring wheat,Spring corn and Spring rape,high benefit could be available even in high water supply level,and limited fertilizers supplying to potato and flax were also practicable.
