| Abstract: | In the paper the Logistic model of rice yield in one unit is established in JiangSanjian farm, by using the discrete formalization of Logistic model the quadric function is obtained, by regression analysis the parameters of the model is solved. By analyzing the model we get the maximum yield of rice and the optimally period of enlarging rice produce. This is very important for guidance agricultural produce and optimal industry structure. |
