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.
In this experiment, quadratic regression orthogonal rotation design test method was used to study the comprehensive agronomic measures for large-area and high-yield cultivation of corn. Based on the relationship between the main factors (density, nitrogen fertilizer, phosphate fertilizer, potash fertilizer, sowing date) and yield in maize cultivation, a mathematical model was established by computer. The model is analyzed and the relationship between the primary and secondary factors affecting the yield and the interaction between the factors are obtained. Also by means of computer simulation test, find out the best agronomic measures under the level of quantitative production, to provide basis for large-area and high-yield cultivation of corn.
