Study on the Nonlinear Model on the Relationship Between the Corn Grain Filling and the Cumulated Temperature |

Abstract: |
In this paper, the change patterns of cumulated temperature between Aug. to Oct. in 1989 and 1990 were established at different time intevals by linear models and nonlinear models, respectively. The Logistic equation model which describes the corn grain filling course was studied accoding to the cumulated temperature model, and another nonlinear relationship model between acumulated temperature and corn grain filling course were also studied. The result from this study showed that the nonliear models could be widely used in the simulation of the grain filling course in cereal crop plants. |
