摘　　要：通过对石阡县黄泥田实施水稻中优85氮磷钾不同施用量和配比的试验,建立了该稻产量的施肥数学模型,得出最佳施肥纯量是N9.48 kg/667 m2、P2O54.21 kg/667 m2、K2O 9.7 kg/667 m2,可获得水稻产量582.1 kg/667 m2。The optimum fertilization mathematical model for Zhongyou 85, a hybrid rice variety, was established by carrying out the experiment of different N, P and K amount and combinations in Shiqian county. The yield of 582.1 kg/667 m^2 could be obtained under the fertilization condition of N 9.48 kg/667m^2 , P2O5 4.21 kg/667 m^2 and K2O 9.7 kg/667m^2.
