摘　　要：采用５因素二次正交旋转设计，对渭北旱原影响陕２２９小麦产量形成的播期、密度、施肥量（Ｎ、Ｐ、油渣）等５项关键性的高产措施进行了定量化的综合研究，建立了渭北旱原陕２２９小麦高产栽培模式，确定了最佳农艺措施组合方案。并利用产量反应模型，研究了各项农艺措施对产量形成的单独反应以及各项农艺措施之间的交互效应。The orthogonal rotational association design with five factors was used to study such five key measures for yield formation as sowing date, plant density andfertilizer application(N,P and oil cak) , etc. Whichmay affect yield formation of wheatcultivar-Shaan-229 on Weibei Rainfed Highland quantitatively and comprehensively,on the basis of which the high-yielding cultivaton model for wheat cultivar-Shaan-229 on Weibei Rainfed Highland thereby to determine the combination schem with thebest agronomy measures. Also, the yield responsive model was used to study the re-sponsive effect of agronomy measures upon yield formation individually as well as the in-ter-effects among each agronomy measure.
