| 摘 要： | 采用“311－B”二次回归最优设计，以氮、碗、钾肥为供试因子，番茄产量为目标函数，对番茄高产数学模型进行了研究。根据模型得出最佳施肥量为；尿素227kg/hm^2，过磷酸钙751kg/hm^2，硫酸钾142kg/hm^2，产量可达63364.10kg/hm^2，利润99366.6元／hm^2，并对氮磷钾单因素效应及交互作用作了具体剖析。 |

| Abstract: | Application 311 B twice regression D the best design,tomatoes were tested with N,P and K.Applying model of tomatoes were studied.From the model,result of the amount of applying fertilizer of the optimization 1 ha land were applied with 227 kg carbamide;751 kg calcium superphosphate;142 kg potassium suiphate,the yield reached 63364 10 kg/ha and the profit was 99 366 60 yuan /ha.Efficiency of single fact and their interaction were analyzed. |
