Abstract:

Based on single leaf light response model and the canopy light distribution, rubber tree canopy photosynthesis model was constructed by integral form. In this model, factors that would affect rubber canopy photosynthetic rate were considered. These factors included the light flux density, temperature, leaf area index, the largest single-leaf photosynthetic rate, photosynthetic characteristic parameters, extinction coefficient, and group reflectivity. Based on the relationship of the respiration rate of leaves and wood organ interact with the environmental factors, the rubber tree respiration model was developed. Based on the canopy photosynthesis model and the respiration model, the dry material accumulation simulation model of rubber tree was constructed. The validation of model for dry matter accumulation with field experiments indicated good fit between the simulated and observed data. Therefore, this model is strong on both mechanism and practicability.
