Research on Method for Estimating Asymmetrical Nutrient Effect Model Parameters

The paper makes further research on estimating the parameters of the asymmetrical model describing effect of nutrient base on present literature, and provides a new method for estimating parameters that this method combines one-dimension search of optimization theory and multiple linear regression. The method not only overcomes the faultiness of estimation methods in existing literature, but also example of calculation shows this method is highly fitting precision, and verifies the validity of the method.
