中文摘要	在内陆河绿洲灌区,通过大田试验,研究了在限量供水条件下,交替灌溉小麦间作玉米与单作小麦,单作玉米土壤水分的时空变化和利用效率,以期为能否将交替灌溉技术集成到间作生产提供理论依据.结果表明:交替灌溉小麦间作玉米全生育期120cm土层内的土壤平均含水量低于单作小麦和单作玉米;间作群体内,玉米带内的土壤含水量始终高于小麦带.与单作小麦和单作玉米产量,水分利用效率(WUE),耗水量的平均值相比,交替灌小麦间作玉米的产量分别提高了32.2%~38.9%,WUE提高了27.8%~36.0%,耗水量增大了4.2%~5.4%
英文摘要	In an inland oasis irrigation area,a field experiment was carried out under limited water supply irrigation to investigate the spatial-temporal distribution and utilization of soil water in sole cropping wheat, corn and alternative irrigated wheat corn intercropping systems. The purpose of the study was to exploit theoretical evidence for combining alternative irrigation technique into intercropping. The results showed that:in the whole growth stage, the average soil water content that in profile of 0-120cm in intercropping systems was both lower than that in the sole cropping wheat and corn;in intercropping systems, the soil water content in the strip of the corn was higher than that in the strip of wheat. Compared to the average of single cropping of wheat and corn, the yield, water use efficiency and water use of wheat corn intercropping were increased by 32.2%-38.9%,27.8%-36.0% and 4.2%-5.4% respectively
