摘　　要：为探讨不同生育期水分亏缺对冬小麦品质、产量及水分利用的影响,本文提出了基于灰色关联投影模型的综合评价方法。结果表明:返青期轻度亏水处理为最优调亏方案,可有效提高冬小麦品质、产量与水分利用率;拔节期轻度亏水处理为最劣调亏方案,冬小麦品质、产量与水分利用指标较低。研究结果为实现冬小麦节水增产提质提供了重要参考。In the paper,a comprehensive evaluation method based on grey relational projection model is proposed in order to discuss the influence of water deficit in different growth periods on winter wheat quality,yield and water utilization. The results show that slight water deficit treatment during the period of seedling establishment is the optimal adjustment plan,which can effectively improve quality,yield and water utilization rate of winter wheat. Slight water deficit treatment during elongation stage is the worst adjustment plan,and the quality,yield and water utilization index of winter wheat are low. The results provide important reference for saving water,and improving the yield and quality of winter wheat.
