| 摘 要： | 在基础肥力底施有机肥4.5万kg/hm2条件下,对新乡市高产水稻田的氮磷钾优化配方施肥进行了研究。通过施肥试验测得的参数,建立了以水稻产量为目标函数的氮、磷、钾三因子效应模型y=9 388.13+251.46x1+1 597.98x2+81.81x3-375.99x12+30.46x1x2-51.92x22+475.41x1x3-808.31x2x3+178.19x32,并依此计算出高产水稻最佳施肥量为纯N 140.3 kg/hm2、P2O597.5 kg/hm2、K2O 109.8 kg/hm2,最佳产量为10 861 kg/hm2。并对单因素效应及两因素互作效应作了剖析。

| Abstract: | The optimum formula fertilization for high-yield rice in Xinxiang was studied using 45 000 kg/hm2 organic fertilizer as base fertilizer.The N,P and K fertilization model was y=9 388.13＋251.46x1＋1 597.98x2＋81.81x3-375.99x12＋30.46x1x2-51.92x22＋475.41x1x3-808.31x2x3＋178.19x32.Based on the model,the optimum fertilization amount for high-yield rice was N 140.3 kg/hm^2,P2O5 97.5 kg/hm^2 and K2O 109.8 kg/hm^2,and the optimum yield was 10 861 kg/hm^2.The single factor effect and the interaction of two factors were analyzed. |
