中文摘要	通过在西北旱区石羊河流域开展的田间灌溉试验,研究了咸水非充分灌溉对春小麦产量、耗水及水分利用效率的影响。结果表明,水分胁迫和盐分胁迫都可造成春小麦不同程度的减产,但轻度盐分胁迫仅减产1%,轻度水分胁迫减产6%;水分胁迫和盐分胁迫均可造成春小麦耗水量的减少,非充分灌溉条件下,春小麦耗水中土壤水贡献的比例增大,有利于节约灌溉水;水分利用效率最高的处理矿化度为3g/L,灌水量为80%ETc,说明适度的水分亏缺和适当浓度的咸水灌溉能够在当地达到节水的效果。
英文摘要	Underground saline water has became an important source of irrigation water because of water shortage in northwest arid regions.This paper discussed the effect of non-sufficient irrigation with saline water on spring wheat yield、water consumption and water use efficiency through a field experiment in the middle reach of Shiyang River Basin.Results showed that either water stress or salt stress caused a decrease on spring wheat yield.But under slight salt stress,yield of spring wheat only reduced by 1%,while it reduced 6% under slight water stress.Water consumption of spring wheat also decreased under water stress or salt stress.The percentage soil water accounted for water consumption of spring wheat increased under non-sufficient irrigation,which was good for saving irrigation water.The treatment of highest water use efficiency was W2S2,which indicated that irrigation with moderate deficiency or saline water could reach the goal of saving water.
