中文摘要	对新疆干旱绿洲灌溉区冬小麦进行了节水灌溉试验研究,研究了不同供水条件对产量及水分利用效率的影响,旨在为新疆冬小麦建立优化灌溉制度、提高水分利用效率和达到节水增产目的提供理论依据.试验结果表明,土壤水所占总耗水量的比例为27.8%～91.2%,灌水量所占总耗水量的比例在28.5%～68.0%,降水量所占总耗水量的比例为4.2%～8.8%.随着灌水次数和灌水量的增加,冬小麦利用土壤水逐渐减少.试验区春季灌二水的最佳组合为:拔节期+扬花期灌水,组合处理产量为6 813 kg/hm2,水分利用效率1.47 kg/m3;春季灌三水的最佳组合为:拔节期+孕穗期+灌浆期灌水,组合处理产量为7 393.5 kg/hm2.水分利用效率1.40 kg/m3.
英文摘要	In this paper, study on water - saving irrigation experiment of winter wheat in arid oasis area of Xinjiang was conducted. The impact of different water supply treatments on yield and water utilized efficiency (WUE) of winter, wheat was analyzed in order to provide a basis for establishing optimum irrigation mode which could increase the yield and improve water utilized efficiency.The experiment results indicated that the ratio of soil water to total water consumption was at 27.8 % ~ 91.2 % j the ratio of water volume irrigation to total water consumption was at 28. 5% ~ 68. 0% ; the ratio of the precipitation to total water consumption was at 4.2% ~ 8. 8 % . Along with the increase of times and water volume of irrigation, the water obsorbed by winter wheat was gradually decreased. The best irrigation combination pattern at pilot area was that( 1) At the beginning of spring, when die jointing and flowering stages started, two - irrigation was made, yield obtained by combination treatment was 6 813 kg/hm2, water utilized efficiency was 1.47 kg/m3; (2) At the beginning of spring , when jointing, booting and filling stages started, three - irrigation was made, yield obtained by combination treatment was 7 393.5 kg/hm2, water utilized efficiency was 1.40 kg/m .
