摘要: 采用三因素二次通用回归旋转设计,对豫南砂姜黑土区影响小麦高产的氮、磷、有机肥的用量进行两年定位试验,建立了小麦产量函数模型;通过模型解析选优,确定了每公顷产量>6000kg、>6750kg、>7500kg及最大经济效益的施肥组合方案;明确了模型因素效应顺序(氮>有机肥>磷肥)和高产与施肥的关系,以及各肥料产量因素间的交互作用效应。

Abstract: Adopting the quadratic regression rotation design,the field locating trial about the effects of the nitrogen(N),phosphorus fertilizer(p),organic fertilizer(M)on the wheat yield had been conducted for two years at shajiang black soil area in south Henan province.The regression models on yield were established, and the combined programmes about fertilizer application for wheat yield being respectively higher than 6000,6750,7500kg/ hm2 and their maximum economic benefit were suggested by optimum seeking method.The effect order of N, P and M interaction among them,and the relations between the wheat yield and expermental factors were simultaneously analysed.

Key words: Winter wheat, Maths model, Optimum fertilization programme, Yield
