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.
