摘　　要：针对石阡县主要水稻土种黄泥田进行"3414"氮磷钾肥配方施肥试验。得出,石阡县黄泥田水稻种植施肥数学模型为y=311.72+25.44x1+12.20x2+5.49x3-0.26x1x2+0.12x1x3+2.20x2x3-1.10x12-2.23x22-0.91x23;最佳施量为:667m2施N 10.487 kg、P 6.222 kg、K 9.267 kg,可获水稻产量533.991 kg/667m2。Abstract： Q you 6, a hybrid rice variety, was tested in the paddy field with yellow soil by using the＂3414＂formulation application technique in Shiqian county. The results showed that the application mathematical model was y=311.72＋25.44x1＋12.20x2＋5.49x3-0.26x1x2＋0.12x1x3＋2.20x2x3-1.10x1^2-2.23x2^2-0.91x3^2; and the yield could be up to 533. 991 kg/ 667m^2 under the optimum application formulation （N 10. 487 kg/667m^2 , P 6. 222 kg/667m^2 and K 9. 267 kg/667m^2）.
