摘　　要：为探索玉米遵玉3号氮、磷、钾养分的施用量,进行了氮、磷、钾肥不同用量配比施用试验。结果表明,氮磷钾肥不同配比施用对遵玉3号产量、肥效有明显的影响。最佳施肥量为N 14.38 kg/667m2、P2O58.61 kg/667m2、K2O 13.83 kg/667m2,N∶P2O5∶K2O=1∶0.60∶0.96,获得了遵玉3号的肥料利用率、肥料农学效率、肥料偏生产力等测土配方施肥技术参数。Zunyu 3, a hybrid maize variety, was tested under different combinations of N, P and K application norm to investigate its optimum application combination. The results showed that the tested different application combinations all had the significant effect on its yield and manurial effect. The optimum application combination is N 14. 38 kg/667m2 , P205 8. 61 kg/667m2 and K2O 13.83 kg/667m2 and its ratio of N ： P2O5 ： K2O is 1 ： 0. 60 ： 0. 96. The application parameters of Zunyu 3 including fertilizer utilization rate, fertilizer agronomic efficiency and fertilizer partial productive forces are obtained at the same time.
