| 摘 要： | 马铃薯施用N、P、K肥"3414"肥效试验表明,在厦门市翔安区当地试验条件下,N、P、K肥均影响马铃薯产量,且N、K肥对产量的影响较P肥大;通过建立回归方程并对回归方程进行分析显示,马铃薯产量与N、P、K施肥量之间存在显著的三元二次回归(F=8.1025F0.05=5.9988;R=0.9737**)关系,推荐N肥马铃薯最高经济产量施肥量为277.64 kg.hm-2,N∶P2O5∶K2O=1∶0.24∶1.93,最高经济产量36657.24 kg.hm-2;N肥最佳经济效益施肥量为229.32 kg.hm-2,N∶P2O5∶K2O=1∶0.30∶1.85,最佳经济效益为36285.41元.hm-2。

| Abstract: | The result of "3414" fertilizer experiment of potato showed that under the local conditions N,P,K influenced the potato yield,and N,K had greater influence than P.By setting a regression equation and analysis of it,it was found that there was a significant relationship of ternary quadratic regression(F=8.1025>F0.05=5.9988;R=0.9737**) between potato yield and N,P,K fertilization amount.For the highest economic yield of potato,N fertilizer has to be applied 277.64 kg·hm-2,N∶P2O5∶K2O=1∶0.24∶1.93,the highest economic yield was 36657.24 kg·hm-2.To obtain the highest economic effect,N fertilizer has to be applied 229.32 kg·hm-2,N∶P2O5∶K2O=1∶0.30∶1.85,the highest economic effect was 36285.41 yuan·hm-2. |
