| Abstract: | The advanced HDRICE model presented here consists of the modules of phonology development of crop, daily dry matter accumulation and partitioning, daily CO 2 assimilation of the canopy, leaf area and tiller development. Because of integrating thoroughly the comprehensive effectives of temperature and light on the rates of crop development, photosynthesis, respiration and other ecophysiological processes, the model could simulate the dynamic of crop development and attainable grain yield. As well as, the model was used to optimize the combination of the transplanting dates, seedling ages and densities for cv. Xieyou 46 at Jinhua region and the population quantitative indexes needed to achieve the potential production, such as : productive ears, LAI and the ratio of the number of spikelets or filled grains to leaf area(cm 2). |
