摘要

The HDRICE model presented in the paper consisted of the modules of morphological development of rice, daily dry matter accumulation and partitioning, daily CO_2 assimilation of the canopy, leaf area and tiller development. Because of thoroughly integrating the effects of temperature and light on the rates of rice development, photosynthesis, respiration and other ecophysiological processes, the model could simulate the dynamic rice development and attainable grain yield. Besides, the model was used to optimize the combinations of the transplanting date, seedlling age and density for cultivar Xieyou 46 at Jinhua area. The rice population quantitative indices needed to achieve the potential production. such as effective panicles, leaf area index and ratio of the spikelet number or filled grains to leaf area could be also obtained by the model.
