| Abstract: | Firstly, one established a mathematical model for available phosphorus density in the soil of some district with the least squares method in the paper. Secondly, one investigated the hypothesis testing for the model,therefore the model is reasonable. Finally, one studied how to forecast and how to control the phosphorus density in the soil. |

| Keywords: | least squares method ternary linear regression model hypothesis testing forecast control |
