采用“3414”田间肥效试验设计，对玉溪市红塔区油菜栽培施用的氮、磷、钾肥肥效进行了试验研究。结果表明，油菜N、P、K配比施肥量与产量的数学模型为y=42.9906+15.5291N+2.1187P-13.1592K-0.8474NP+0.2745NK+1.0717PK-0.2330N2+0.9174P2+0.2712K2，油菜N、P、K的最佳施肥量分别为纯N20.66kg/667m2、P2O56.80kg/667m2、K2O3.65kg/667m2，最佳经济产量为206.45kg/667m2。
採用“3414”田間肥效試驗設計，對玉溪市紅塔區油菜栽培施用的氮、燐、鉀肥肥效進行瞭試驗研究。結果錶明，油菜N、P、K配比施肥量與產量的數學模型為y=42.9906+15.5291N+2.1187P-13.1592K-0.8474NP+0.2745NK+1.0717PK-0.2330N2+0.9174P2+0.2712K2，油菜N、P、K的最佳施肥量分彆為純N20.66kg/667m2、P2O56.80kg/667m2、K2O3.65kg/667m2，最佳經濟產量為206.45kg/667m2。

By the‘3414’experimental design of fertilizer effectiveness,the fertilizer efficiency of N,P and K of the rape in Hongta (Yuxi) were studied. The mathematical model between the fertilizing amount of N, P and K and the yield is y=42.9906+15.5291N+2.1187P-13.1592K-0.8474NP+0.2745NK+1.0717PK-0.2330N2+0.9174P2+0.2712K2. When the best fertilizing amount are respectively N20.66kg/667m2,P2O56.80 kg/667m2 and K2O3.65kg/667m2,the best yield is 206.45kg/667m2.
