采用"3414"试验研究水稻氮磷钾养分用量优化,结果表明:水稻产量受氮肥影响最大,其次是磷肥,钾肥影响较小。多元回归方程分析表明,每667m2施用氮、磷、钾养分分别为13.96kg、7.54kg和16.85kg时水稻产量最高为642.81kg,结合海南琼中水稻生产的实际,建议水稻生产中每667m2施用氮、磷、钾养分分别为10~11kg、6~7kg和9~11 kg,此时氮、磷、钾养分配比以1∶0.60~0.64∶0.9~1.0较合适。
採用"3414"試驗研究水稻氮燐鉀養分用量優化,結果錶明:水稻產量受氮肥影響最大,其次是燐肥,鉀肥影響較小。多元迴歸方程分析錶明,每667m2施用氮、燐、鉀養分分彆為13.96kg、7.54kg和16.85kg時水稻產量最高為642.81kg,結閤海南瓊中水稻生產的實際,建議水稻生產中每667m2施用氮、燐、鉀養分分彆為10~11kg、6~7kg和9~11 kg,此時氮、燐、鉀養分配比以1∶0.60~0.64∶0.9~1.0較閤適。

An experiment,adopting the theory of "3414" regression optimum design,were conducted to optimize NPK application rates for Rice.The results illustrated that yield of rice was mostly affected by nitrogen,followed by phosphorus,and potassium was less.Regression analyses concluded that the highest yield was 642.81 kg/667 hm2,the appropriate application rates of N,P2O5,K2O were 13.96,7.54 and 16.85 kg/667m2.The recommendation was that the appropriate application rates of N,P2O5,K2O were10~11,6~7 and 9~11 kg/667m2,the rational proportion of N∶ P2O5∶ K2O was 1∶ 0.60~0.64∶ 0.9~1.0 in Qiongzhong County.
