确定最佳经济用肥量的多项式回归模型

Determine the Most Economy Quantity of Fertilizer Using Polynomial Regression Model

利用多项式回归模型给出了用氮量与玉米产量间的关系,并对最高单产量时的用氮量以及最佳经济用肥量予以确定。

This article produces the relationship between the quantity of applying nitrogenous fertilizer and corn production by means of polynomial regression, based on which we determined the exact quantity of nitrogenous fertilizer we should use and the quantity of fertilizer in the most economy way when yield the highest output per unit area.
