中文摘要	2001年在内蒙风沙区对春小麦进行了各生育阶段不同程度亏缺灌溉的试验研究，结果表明，春小麦不同生长时期、不同程度的水分亏缺对其生长发育、产量构成及水分生产效率会产生不同的影响。拔节一孕穗期受旱对株高、叶面积、穗粒数影响最大，减产最多，其次是抽穗-开花期干旱；灌浆成熟期受旱主要影响千粒重。在同一生育阶段，水分亏缺越严重，春小麦受害越深。在春小麦生长前期适度的水分胁迫不但对产量无显著影响，反而有利于提高水分生产效率。
英文摘要	A field experiment to study influences of deficit irrigation at different growth stages to spring wheat growth and development was conducted in windy desert area in Inner Mongolia in 2001. Results showed that water deficits at various levels in different growth stages brought about different effects on growth, development, yield components and water use efficiency in spring wheat. The water deficit occurred during jointing stage to booting stage had the greatest effects on plant height, leaf area index, grain number per plant and grain yield, and the second greatest effects for water deficit occurred during heading stage to flowering stage. Water deficit in period of grain-filling to harvesting stages affected the 100-grain weight mainly. In same growth stage, the more serious the water deficit was, the greater the yield decreased. But moderate degree of water deficit at early stage of spring whet did not affect yield significantly, which improved water use efficiency.
