| 摘要: |
| 【目的】揭示深度节水对荒漠绿洲区滴灌冬小麦产量、品质及水分生产力的影响。【方法】以“新冬20”冬小麦为供试材料，于2021—2023年开展田间试验，以全生育期充分灌溉为对照（CK）、设置全生育期中度、重度控水（FM、FS）、返青—拔节期轻度、中度控水（VL、VM）及抽穗—成熟期轻度、中度控水（RL、RM）共7个处理，分析不同控水处理对冬小麦产量、品质及水分生产力的影响，建立TOPSIS综合评价体系。【结果】随着滴灌控水程度的加重，冬小麦产量、水分生产力（WP）、灌溉水生产力（IWP）、籽粒蛋白质量和根系吸水率呈先升高后降低的趋势，面筋指数、湿面筋和沉淀值呈升高趋势，出粉率呈降低趋势；FM处理下的产量、籽粒蛋白质量和WP较CK提升1.4%、6.4%和8.5%；TOPSIS综合评价结果表明，全生育期中度控水处理下的冬小麦综合评价得分最高。【结论】全生育期中度控水处理下的冬小麦产量、品质及WP表现较佳，是南疆荒漠绿洲区滴灌冬小麦适宜的灌溉阈值。 |

| Abstract: |
| 【Objective】Water scarcity is a main limiting factor for agriculture in desert oases in southern Xinjiang. Implementing intensive yet rational water-saving irrigation is critical to sustaining grain production and improving crop quality in this region. This study experimentally investigated the effects of intensive water saving on grain yield, quality and water productivity (WP) of drip-irrigated winter wheat in local desert oases.【Method】A two-year experiment was conducted from 2021 to 2023 in a wheat field using the cultivar Xindong 20 as the model crop. The experiment included seven treatments: sufficient irrigation (CK), moderate water stress (FM) and severe water stress (FS) during the entire growing season, mild water stress (VL) and moderate water stress (VM) during the regreening–jointing stage, and mild water stress (RL) and moderate water stress (RM) during the heading–maturity stage. During the experiment, we measured the yield, grain quality and water productivity of the wheat. The optimal irrigation method was determined using the TOPSIS method.【Result】With increasing water stress, grain yield, water productivity (WP), irrigation water productivity (IWP), grain protein content and water adsorption first increased and then decreased, while the gluten index, wet gluten content and sedimentation value increasing continuously accompanied by a continuous decrease in flour yield. Compared with CK, the FM increased grain yield, grain protein content, and water productivity by 1.4%, 6.4% and 8.5%, respectively. The TOPSIS analysis showed that the FM was the optimal water-saving irrigation for wheat production in the study region.【Conclusion】Applying moderate water stress throughout the entire growing season is the optimal water-saving irrigation strategy for drip-irrigated winter wheat in desert oases of Southern Xinjiang; it achieves a coordinated balance among grain yield, grain quality, and water productivity. |
