摘　　要：采用“3414”平衡施肥试验设计对油菜黔油16号进行施肥试验,建立黔油16号油菜产量与氮磷钾3因素施用量的回归方程。研究结果表明,黔油16号在纯N施用量8.84 kg/667m2、P2O5施用量5.31 kg/667m2、K2O施用量7.4 kg/667m2时可获得169.47 kg/667m2的最佳产量。The regression equation between the yield of Qianyou 16 and amounts of N, P and K fertilizer was established by the “3414” balance application experiment. The results show that the maximum yield （169.47 kg/667m^2） can be obtained by applying 8.84 kg/667m^2 of N, 5.31 kg/667m^2 of P and 7.4 kg/667m^2 of K for Qianyou 16.
