中文摘要	基于中国北方干旱地区18年的长期秸秆还田田间定位试验，开展了不同秸秆还田方式及施肥时期对春玉米产量及水分利用效率影响的比较研究。结果表明：与春施肥对应处理相比，不同方式秸秆还田秋施肥具有显著增产效果，18年累计增产玉米籽粒9.71~15.58 t/hm~2，增产率为8.33%~16.19%；同时，玉米生育期耗水量减少，土壤贮水量增加，水分利用效率明显提高。4种不同秸秆还田方式对春玉米18年总产量、总水分利用效率的贡献从大到小依次为：秸秆过腹还田、秸秆覆盖还田、秸秆粉碎直接还田、秸秆未还田。不同的降水年型，对各处理玉米产量和水分利用也存在较大影响。正常年型玉米产量最高，偏旱年型玉米水分利用效率最高。秸秆覆盖还田秋施肥对偏旱年份的增产及水分利用效率提高的效果尤为突出。
英文摘要	Based on the results from 18-year long-term location experiment in dryland experimental area of northern China, the effects of various kinds of straw return to field such as no straw returning (CK), straw mulching (SM), straw crushing (SC), cattle manure (CM) and different fertilization time i.e. spring and autumn on corn yield and water use efficiency were studied. The results showed that the experiment of combining autumn fertilizing with returning stalks to field could increase the yield and water use efficiency of spring maize significantly compared to the spring fertilizing, meanwhile, it decreased the accumulated water consumption and increased the soil water storage amount. The results showed that autumn fertilizing increased 9.71~15.58 t/hm~2in yield, compared with spring fertilizing. The range of increased in yield was 8.33%~16.19%. The total corn yield and water use efficiency in the past 18-year decreased in the following order: CM>SM>SC>CK. In different rainfall years, the corn yield and water use efficiency were very different. In normal years, the corn yield was highest. In dry years, the water use efficiency of spring maize was highest and yield increasing effect from straw mulching combining with autumn fertilizing was striking.
