| Abstract: | According to the tillering law of rice, we establish its forecast model. Inorder to improve its precision, we make the parameters grey in the model andestablish the grey model. Moreover, on the basis of experimental data, some sub-models of parameters are also put forward in this paper. |

| Keywords: | number of stems of rice community grey forecast model |
