摘 要:采用二次回归正交旋转设计方法,研究了浙春2号春大豆主要栽培因子(密度、氮肥、磷肥、钾肥)与大豆产量的关系,建立了浙春2号春大豆在三明红黄壤条件下的高产栽培数学模型。通过PC-1501计算机对模型的解析,得出各因子对产量效应的主次关系,两因子搭配的产量效应。通过频数分析,得出指定产量水平下的最佳农艺措施组合方案,为浙春2号春大豆大面积规范化栽培提供依据。A mathematical model for high yielding cultivation of Zhechun 2 spring soybean had been built up for haplic ferralsols condition in Sanming region. Method of quadratic second order regression rotation design was used to study the relationship between the main cultivation factors (density,N,P,K) and soybean yield The analysis of mathematical model was conducted by PC 1501 computer Different effect of cultivation factors on yield and the combinative effect on yield by 2 factors were worked out.The optimal combinative scheme of comprehensive agronomic measures for top yield level was showed by the frequency number analysis Scientific basis was provided for spring soybean Zhechun 2 on model cultivation in large areas
