[目的]确定海南省保亭县水稻的最佳氮、磷、钾施肥配比,为水稻配方施肥提供科学依据。[方法]以神农326为供试品种,采用＂3414＂最优回归设计研究不同施肥方案对水稻产量及其构成因素的影响,并通过拟合三元二次和一元二次肥效模型,确定水稻的推荐施肥量。[结果]水稻有效穗和穗粒数随氮、磷、钾肥施用量的增加呈先增加后下降的趋势;结实率随氮、磷肥施用量的增加呈下降趋势;氮、磷、钾肥对千粒重没有明显的影响。多元回归方程分析表明,氮、磷、钾肥料施用量分别为211.20、69.90、183.60 kg/hm2时水稻产量最高,为7 977.75 kg/hm2。[结论]氮、磷、钾三要素中,氮肥对水稻产量影响最大,依次是磷肥、钾肥。结合海南保亭县水稻生产实际,建议氮、磷、钾肥施用量分别为150～180、60～75、105～135 kg/hm2,此时氮、磷、钾肥配比以1（∶0.40～0.50）（∶0.70～0.90）较合适。
[目的]確定海南省保亭縣水稻的最佳氮、燐、鉀施肥配比,為水稻配方施肥提供科學依據。[方法]以神農326為供試品種,採用＂3414＂最優迴歸設計研究不同施肥方案對水稻產量及其構成因素的影響,併通過擬閤三元二次和一元二次肥效模型,確定水稻的推薦施肥量。[結果]水稻有效穗和穗粒數隨氮、燐、鉀肥施用量的增加呈先增加後下降的趨勢;結實率隨氮、燐肥施用量的增加呈下降趨勢;氮、燐、鉀肥對韆粒重沒有明顯的影響。多元迴歸方程分析錶明,氮、燐、鉀肥料施用量分彆為211.20、69.90、183.60 kg/hm2時水稻產量最高,為7 977.75 kg/hm2。[結論]氮、燐、鉀三要素中,氮肥對水稻產量影響最大,依次是燐肥、鉀肥。結閤海南保亭縣水稻生產實際,建議氮、燐、鉀肥施用量分彆為150～180、60～75、105～135 kg/hm2,此時氮、燐、鉀肥配比以1（∶0.40～0.50）（∶0.70～0.90）較閤適。

[Objective] The scientific basis of prescription fertilization of rice in Baoting county was provided through the research on the best ratio of nitrogen,phosphorus and potassium fertilizer.[Method] The effect of the different fertilization program on yield components and yield of rice Shennong 326 variety was experimented with the optimal regression design（＂3414＂） and the recommended fertilization for rice was determined.[Result] With the increment of nitrogen,phosphorus and potassium fertilizer,the available panicle and grain number per spike were firstly increased and then decreased.The rate of seed-setting was decreased with the increment of nitrogen and phosphorus fertilizer.The nitrogen,phosphorus and potassium fertilizer had no signification effect on grain weight.The multiple linear regression analysis concluded that the highest yield was 7 977.75 kg/hm2,the appropriate application rate of nitrogen,phosphorus and potassium fertilizer was 211.20,69.90,183.60 kg/hm2.[Conclusion] In the experimental condition,the nitrogen fertilization could result in the best efficiency;then,the phosphorus and last the potassium.Combined with local production practice,the recommended application rate of nitrogen,phosphorus and potassium fertilizer was 150 ～ 180、 60 ～ 75、105 ～ 135 kg/hm2,the rational proportion of nitrogen,phosphorus and potassium fertilizer was 1∶（0.40 ～ 0.50）∶（0.70 ～ 0.90） in Baoting county of Hainan province.
