摘要
采用旋转回归正交试验 ,探讨了不同肥量、密度条件下对小麦产量的影响。建立了产量与种植密度、施肥量之间关系的数学模型及 6个子模型。初步揭示了密度、肥量对小麦产量的影响程度及相互间变化规律 。
Through the rotating,regressive and perpendicular experiment and study of the effect of wheat yield between different fertilizer quantity and density.The wheat yield and the relation between the general regressive models as well as the 6 filial models of fertilizer quantity and density have been created.It reveals to what extent the density and fertilizer can affect wheat yield.The maximum of wheat yield in theory has been found.$$$$
