摘　　要：对确定用肥量与产量的依存关系问题,采用正交多项式回归加以处理,给出了拟合关系以及所得结果的应用,改进了以前的解决方法.Whithin this paper, based on orthogonal polynomial regression the dependence relationship between the dosage of fertilizer and the barley output is confirmed. At the same time the simulation effect and the application of the received result are also proposed which shows that it makes progress compared with former methods.

关 键 词：回归建模 正交多项式 拟合关系 交互作用
