在两点进行＂3414＂肥料试验,通过肥料效应函数拟合,研究了氮磷钾肥不同比例配施对大豆产量的影响。结果表明：氮磷钾肥配施能够显著提高大豆产量,单株粒数受磷施用量影响较大,百粒重受氮磷施用量影响较大。推荐的高产施肥量为：N75～85kg/hm2、P2O565～70kg/hm2、K2O45～55kg/hm2,比例为：N：P2O5：K2O=1.60：1.35：1;经济施肥量为：N65～75kg/hm2、P2O545～50kg/hm2、K2O30～40kg/hm2,比例为：N：P2O5：K2O=2：1.36：1。

Effect of different proportion of N, P, K on soybean yield was studied in the two places by use of ＂3414＂ test and fertilizer effect function fitting. The result showed that proportion of N, P, K improved soybean yield significantly, phosphorus fertiliz- er effected seed number per plant mainly, nitrogenous and phos- phorus fertilizer effected 100-seed weight significantly. It was recommended that fertilizer amount for high yield was N 75 - 85 kg/hm2, P20 565- 70 kg/hm2, K20 45 - 55 kg/hm2, the opti- mum proportion of N, P, K was 1.60：1.35：1, economical fertilizer amount was N 65- 75 kg/hm2, P20 545 -50 kg/hm2, K20 30 - 40 kg/hm2, the optimum proportion of N, P, K was 2：1.36：1.
