中文摘要	【目的】明确新疆南部极端干旱区滴灌小麦目前灌量是否合理及灌水量阈值。通过分析新疆南部极端干旱区滴灌小麦在水分利用方面的现状,为进一步解析滴灌冬小麦产量提升及节水灌溉的关键要素和限制因子提供研究基础。【方法】设计四种减量灌溉模式(总灌量分别为3 376、3 000、2 625和2 250 m~3 /hm~2) 。以常规灌量为对照(总灌量为3 750 m~3 /hm~2) 。监测冬小麦产量及水分利用效率。【结果】D4处理(灌量2 250 m~3 /hm~2)到D3处理(灌量2 625 m~3 /hm~2)产量逐步增加,D3处理产量最高为9 450 kg /hm~2,随灌溉量的增加,产量逐步降低。【结论】D4(灌溉量2 250 m~3 /hm~2)到D2处理(灌溉量3 000 m~3 /hm~2)水分利用效率逐步增加,而后波动性下降。说明灌溉量超出其阈值,水分利用效率随灌溉量的增加反而减少。
英文摘要	【Objective】This study is designed to find out whether the current wheat drip irrigation and irrigation amount are reasonable amount threshold in extremely arid area in Southern Xinjiang. 【Method】The four irrigation reduction modes were designed (the total amount of irrigation was 3,376 m~3 /hm~2,3,000 m~3 / hm~2,2625 m~3 /hm~2,2250 m~3 /hm~2). The conventional irrigation volume control served as the control (total irrigation capacity of 3,750 m~3 /hm~2) to monitor the yield and water use efficiency of winter wheat. 【Result】 The results showed that: D4 treatment (irrigation capacity 2,250 m~3 /hm~2) to D3 treatment (irrigation volume 2,625 m~3 /hm~2) could gradually increase the production,D3 treatment yield was up to 9,450 kg /hm~2,and then,with the amount of irrigation increase,the production would gradually decrease. 【Conclusion】From D4 treatment to D2 treatment (irrigation capacity 3,000 m~3 /hm~2),the water use efficiency was gradually increased, and then volatility decreased,which showed the irrigation amount exceeded its threshold,thus reducing water use efficiency with the increased amount of irrigation. By analyzing the status of wheat in arid zone irrigation water use areas in extremely dry Southern Xinjiang,a basis for further research has been provided to resolve the key elements in order to enhance the yield of winter wheat and raise the limiting factors in water - saving drip irrigation.
