中文摘要	在河西绿洲灌区,通过大田试验,研究了交替灌溉小麦间作玉米的产量及水分利用效率(WUE). 结果表明,交替灌溉小麦间作玉米的产量及WUE较单作显著提高. 在低、中、高3个灌水水平下,间作土地当量比分别为1.30、1.35、1.38;净占地面积上间作小麦经济产量较单作小麦分别提高了20.96%、28.34%、33.10%,间作玉米经济产量较单作玉米分别提高了38.30%、41.65%、41.98%,间作增产作用显著;间作耗水量较相应单作耗水量的加权平均分别增加了5.37%、4.71%、4.18%;WUE间作较单作小麦和单作玉米分别提高了55.97%、63.86%、68.46%和8.29%、12.71%、14.02%,WUE间作与单作小麦差异显著,但与单作玉米差异不显著
英文摘要	A field experiment was carried out to investigate the yield and WUE of alternative irrigated wheat corn intercropping in an oasis irrigation area. The results showed that: Wheat corn intercropping combined with alternative irrigation could increase the land utilization efficiency, crop yield and WUE significantly. At the irrigation level of low, medium, high respectively, the LER of intercropping systems was 1.30,1.35,1.38 respectively. The yield of intercropping wheat was 20.96%,28.34%,33.11% higher than that of the sole ones at different water supply levels, and the yield of corn was increased by 38.30%,41.65%,41.98% compared to that of the sole ones, yield difference between intercropping and sole cropping was significant. Water consumption of intercropping system was 5.37%,4.71%,4.18% higher than that of the weighted mean of the sole wheat and sole corn respectively. The WUE of wheat corn intercropping combined with alternative irrigation was increased by 55.97%,63.87%,68.47% and 8.29%,12.72%,14.02% compared to sole wheat and corn, the WUE difference between intercropping system and sole wheat was significant, but the difference between the intercropping and the sole corn was not significant
