摘要
本文介绍的ＨＤＲＩＣＥ模型由水稻形态发育、干物质积累和分配、ＣＯ２同化、叶面积和分蘖动态等模块组成．模型充分考虑光温等气象因子对水稻发育速率、光合和呼吸速率等生理生态过程的综合效应，能较好地模拟杂交晚稻在一定气候条件下的发育动态和潜在产量．模型还用于优化协优４６品种在金华地区移栽期、苗龄和基本苗的组合以及为取得潜在产量所必须的茎蘖、叶面积发育动态。
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).
