采用“3414”最优回归设计方案，建立了天水市山旱地冬小麦产量与氮、磷、钾肥之间的回归方程。得出当地冬小麦最佳施肥量为尿素289.8 kg/hm2、普通过磷酸钙493.8 kg/hm2、硫酸钾138.9 kg/hm2，该施肥水平下冬小麦产量可达3 255.75 kg/hm2。

Using the “3414” optimal regression design， the regression equation between winter wheat yield and nitrogen， phosphorus and potassium fertilizer in mountainous dryland of Tianshui City was established. The results showed that the optimum amount of fertilization for local winter wheat was urea 289.8 kg/hm2， calcium superphosphate 493.8 kg/hm2 and potassium sulfate 138.9 kg/hm2. The yield of winter wheat could reach 3 255.75 kg/hm2 under this fertilization level.
