摘要
本试验采用二次回归正交旋转设计试验方法,对玉米大面积高产栽培综合农艺措施进行了研究。以玉米栽培中的主要因子(密度、氮肥、磷肥、钾肥、播期)与产量的关系,通过微机建立了数学模型。并对模型进行解析,求出各因子对产量影响的主次关系及因子间的交互作用。还借助微机模拟试验,寻出定量生产水平下的最佳农艺措施,为玉米大面积高产栽培提供依据.
The experiment was conducted with the square-regression-orthogonal-gyrating design
to study the comprehensive agronomical practices for high yield of corn at a large scale.A
mathematical model,involving the main factors affecting the corn yield(density,nitrogenous,
phosphatic and,potassium fertilizers,and sowing date)was establlished and analysed,effects
of individual factor and its interaction on the yield were determined and the optimum
agronomic practices in certain conditions were found in a simulation test.It was available for
the high yield cultivation of corn.
