摘　　要：[目的]为小麦优质高效生产提供科学依据。[方法]以冬小麦品种藁城8901和烟农15为材料,研究花后不同灌水处理W0（不灌水）、W1（花后7 d灌1次水）、W2（花后7、14 d灌2次水）、W3（花后7、14、21 d灌3次水）、W4（花后7、14、21、28 d灌4次水）对其产量和品质的影响。[结果]烟农15在W3条件下千粒重最大。在W0条件下烟农15的千粒重最低,总蛋白和谷蛋白含量最高,可溶性谷蛋白含量随灌水次数增加而下降;灌水处理的湿面筋含量及吸水率大于W0,但面筋形成和稳定时间小于W0。藁城8901在W2条件下千粒重和产量最高,W0条件下总蛋白、单体蛋白和可溶性蛋白含量最高,W1条件下谷蛋白总量和不溶性蛋白含量最高。[结论]花后灌水对不同小麦品种产量和品质的影响不同。兼顾小麦高产优质的灌水模式是花前灌水135 mm,花后灌水30～60 mm。[Objective] The aim was to provide the scientific basis for wheat production with good quality and high effectiveness.[Method] With winter wheat varieties such as Gaocheng 8901,Yannong 15 as the material,the effects of different post-anthesis irrigation treatments W0（no irrigation）,W1（1 time irrigation at 7 d post-anthesis）,W2（2 times irrigation at 7,14 d post-anthesis resp）,W3（3 times irrigation at 7,14,21 d post-anthesis resp）,W4（4 times irrigation at 7,14,21,28 d post-anthesis resp.） on their yield and quality were investigated.[Result] The 1 000-grain weight of Yannong 15 under W3 condition was the biggest.Under W0 condition,the 1 000-grain weight of Yannong 15 was the least,and the contents of total protein and glutelin were the highest,the content of soluble glutelin was decreased with the increase of irrigation times;the wet gluten content and water Absorption of irrigation treatments were bigger than those of W0,but the gluten formation and dough ball time were less than those of W0.The 1 000-grain weight and yield of Gaocheng 8901 was the highest under W2 condition and its contents of total protein,monomeric protein and soluble protein were the highest under W0 condition and its gluten amount and insoluble protein content were the highest under W1.[Conclusion] The effects of post-anthesis irrigation on yield and quality of different wheat varieties were different.Consideration to irrigation model of high yield and quality wheat,135 mm water should be irrigated befor flowering,and 30-60 mm after flowering.
