摘 要 ：应用回归正交设计对确定补骨脂最佳施肥量进行了探讨。经回归方程显著性检验后建立回归方程(?)=25.21+9.18_XN+15.68_XP-0.4_XN²-0.98_XP²+0.062_{XN XP},描述产量与施吧量的相互关系。

Abstract:This paper probes into the determination of the optimum amount of fertilization by applying regression orthogonal design. After a significance teat by regression equation, a regression equation can be set up, i. e. Y=25.21+9.18Xn+15.68 Xp-0.4Xn²-0.98Xp³+0.062Xn Xp. This equation can he used to describe the relationship between yield and amount of fertilization.
