通过海南保亭晚稻“3414”肥效试验，建立了此试验条件下的三元二次和一元二次回归方程模型。结果表明：三元二次方程差异达到极显著水平，预测最佳施肥量的方案为：施N 6.22kg/667m2，P2O51.14kg/667m2， K2O 4.73kg/667m2，氮磷钾比例为1∶0.18∶0.76；缺素区氮素相对产量为83.83%，磷素为92.19%，钾素为87.3%，各单质肥料对水稻产量贡献率依次为氮＞钾＞磷，该试验地土壤养分，氮、磷、钾均为中等肥力。

This paper introduced the field experimental results of“3414”fertilizer response to late rice in Baoting county of Hainan province.According this testing had got ternary quadratic equation and single qua-dratic equation of fertilizer effect.The results showed that the tamari quadratics equations were extremely significant and the best economic applications of fertilizer were N 6.22kg/667m2,P2O5 1.14kg/667m2,K2O 4.73kg/667m2,the proportion was 1∶0.18∶0.76.Relative yield of fertilizer shortage area,N 83.3%,P2O5 92.2%, K2O 83.7%,respectively.On rice yield contribution rate are nitrogen,second potassium,phosphorus last.The testing soil’nitrogen,phosphorus,potassium and has medium fertility.
