摘    要:依据文献资料和田间试验 ,建立了基于生理生态过程的水稻茎蘖增长与消亡的模拟模型。用指数函数描述潜在茎蘖数增长量与叶龄之间的关系。采用品种分蘖特性、有效分蘖叶位数、群体叶面积指数 (LAI)以及植株含氮量等影响因子对潜在茎蘖增长量进行调节 ,从而得到实际生长条件下茎蘖数增长动态模型。拔节至抽穗期间 ,分蘖的衰亡量决定于分蘖的生理年龄和同化物供应状况。利用有广泛生态条件和栽培条件变异的试验资料对模型检验的结果显示 ,模型能较好地模拟茎蘖数增长和衰亡动态。

关 键 词:水稻  茎蘖动态  模拟模型

Abstract:Based on the literatures and the field experiments, the processed based model for simulating tiller increase and decrease in rice was developed. An exponential function was used to describe the relationship between leaf appearance and potential increase of tillers. The variety tillering potential, effective tilllering leaf position and factors of leaf area index and leaf nitrogen content were quantified to adjust the potential increase of tillers for the actual increase of tillers. From jointing to heading, the assimilate supply factor and the physiological age of tillers were used to calculate the decrease of tillers. Validation of the model using the experiment data from a wide range of ecological and cultural conditions showed that the model could well simulate the dynamic changes in the tiller increase and decrease.
Keywords:rice  tiller dynamic  simulation model
