【摘要】 采用二次回归旋转设计方法，研究了玉米闽单 ８８ 主要栽培因子（密度、 Ｎ 肥、 Ｐ 肥、 Ｋ 肥）与制种产量的关系，通过微机对模型进行模拟，得出各因子对制种产量效应的主次关系及２ 因子搭配的产量效应．通过频数分析，筛选出指定产量水平下的最佳农艺措施组合方案，建立了闽单８８ 在三明红黄壤条件下的高产制种数学模型更多还原

【Abstract】 Method of quadratic second order regression rotation design was used to study the relationship between the main corn cultivation factors (density, N, P, K) and corn seed production yield. A high yield mathematical model of cultivation methods of corn Mindan 88 had been built up in Sanming under haplic ferralsols soil conditions. The analysis of mathematical model was conducted by computer. Different effects of cultivation factors on seed production yield and the combined effects of 2 factors on the yield were obtained. The optimal combinative scheme of comprehensive high yield agronomic measures for top yield level was shown by the frequency number analysis. Scientific evidence was furnished for corn Mindan 88 seed production on model cultivation in large areas.更多还原
