摘要： 采用5因素二次通用旋转组合设计，研究了强筋小麦的播期、基本苗、施氮量、施磷量和施钾量等5项农艺措施与产量和品质的关系及其交互作用；建立了产量、粗蛋白质含量、湿面筋含量、吸水率、面团形成时间、面团稳定时间和弱化度等7个目标性状的数学模型；实现7 500kg/hm2以上产量水平、品质指标达国家强筋小麦二级以上标准的最佳农艺措施方案为：播期10月6~7日，基本苗104.8~106.8万/hm2，施氮（N）量294.9~308.0kg/hm2，施磷（P2O5）量139.2~152.2kg/hm2，施钾（K2O）量180.1~200.3kg/hm2；经在同样生态类型区45.9 hm2麦田示范应用，效果非常显著。

Abstract: By using five-elements two times all-purpose gyration combination design,a study was conducted on the relationship among strong gluten wheat yield,quality level and the five agronomy measures,such as the sowing time,basical seeding,application of N-norm,P-norm,as well as K-norm,and their interactive effect.The mathematics models were set up in its yield,crude protein content,wet wheat gluten content,water absorption rate,the time of dough formation and dough steadiness and weakening grade.To realize the yield of over 7 500kg/ha and the quality level which is up to two-grade national standard of strong gluten wheat,the finest agronomy measures were:the sowing time being Oct.6-7,basical seeding being 1048000~1068000/ha,application N-norm being 294.9~308.0kg/ha,application P2O5 being 139.2~152.2kg/ha,application K2O being 180.1~200.3kg/ha.It was applied by demonstration in wheat fields of 45.9 ha in the same ecotype area,showing a significant result.
