本试验采用二次回归旋转设计方法.研究了杂交玉米闽单88主要栽培因子(密度、氮肥、磷肥、钾肥)与制种产量的关系.通过微机对模型的解析,得出各因子对制种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,筛选出指定产量水平下的最佳农艺措施组合方案.建立了阐单88在三明红黄壤条件下的高产制种数学模型,为闽单88大面积规范化制种提供依据。
In this study, the quadratic regression rotation design method was used to study the relationship between the main cultivation factors (density, nitrogen fertilizer, phosphate fertilizer, potash fertilizer) and the seed yield of hybrid maize cultivar Min-dn 88. Through the analysis of the model by computer, Yield effect of the primary and secondary relationship between the two factors with the yield effect, through frequency analysis, screening out the best combination of agronomic practices at the specified yield level.Established a single 88 in Sanming red and yellow soil under high yield seed production mathematical model, To provide a basis for the large-scale standardization of seed production in Fujian province.
