| 摘 要： | 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。

| Abstract: | 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 fertilizer effected seed number per plant mainly,nitrogenous and phosphorus fertilizer effected 100-seed weight significantly.It was recommended that fertilizer amount for high yield was N 75～85 kg/hm2、P2O 565～70 kg/hm2、K2O 45～55 kg/hm2,the optimum proportion of N,P,K was 1.60:1.35:1,economical fertilizer amount was N 65～75 kg/hm2、P2O 545～50 kg/hm2、K2O 30～40 kg/hm2,the optimum proportion of N,P,K was 2:1.36:1. |
