采用"3414"二次回归D—最优设计,对影响水稻产量的氮、磷、钾三要素进行试验,建立融安县中低产红泥田双季晚稻施肥函数模型:y=3811.92+24.48N+6.3P+6.86K-0.10N2-0.43P2-0.09K2+0.13NP+0.01NK+0.23PK。通过该模型推算最高和最佳产量施肥量,并进行仿真模拟寻优,探索出产量大于5 700kg/hm2的施肥方案:N 135.8~195.8kg/hm2、P2O549.5~74.8kg/hm2、K2O 94.6~145.4kg/hm2,N∶P2O5∶K2O=1∶0.36~0.38∶0.70~0.74。
採用"3414"二次迴歸D—最優設計,對影響水稻產量的氮、燐、鉀三要素進行試驗,建立融安縣中低產紅泥田雙季晚稻施肥函數模型:y=3811.92+24.48N+6.3P+6.86K-0.10N2-0.43P2-0.09K2+0.13NP+0.01NK+0.23PK。通過該模型推算最高和最佳產量施肥量,併進行倣真模擬尋優,探索齣產量大于5 700kg/hm2的施肥方案:N 135.8~195.8kg/hm2、P2O549.5~74.8kg/hm2、K2O 94.6~145.4kg/hm2,N∶P2O5∶K2O=1∶0.36~0.38∶0.70~0.74。

To adopt a math design, an experiment of N, P and K effectiveness was conducted to obtain a math model for fertilization: y=3811.92+24.48N+6.3P+6.86K-0.10N2-0.43P2-0.09K2+0.13NP+0.01NK+ 0.23PK. By means of this model, the fertilizations of highest yield and best yield will be obtained. The fertilization program for yield more than 5700kg/hm2:N135.8-195.8kg/hm2,P2O5 49.5-74.8kg/hm2, K2O94.6-145.4 kg/hm2, N : P2O5: K2O=1 : 0.36-0.38: 0.70-0.74.
