| Abstract: | Based on the theories of phsiology and meteorology, models of dry matter accumulation and photosynthesis were established. In these models, leaf area dynamic, light interception, phtosynthsis and respiration were included, and the effects of temperature, fertilizer and other green part were considered. The results of validation showed that, the correlation coefficient between simulated and observed values of dry matter accumulation was 0.9046, and the standard error was 310.305kg/hm 2. |
