| Abstract: | The mathematic model was established by orthogonal quadratic regression design with 3 factors.The dosages of nitrogen,phosphorous and potassium for the highest and lowest yield were obtained through optimizing the mathematical model.Through processing and analyzing the factors relative to fertilization by computer,the specific formulas and dosages of common fertilizer and special compound fertilizer were gotten and the automation of formulizing fertilizer for crop was realized. |
