Abstract:An attempt was made to establish a model for simulating the biomassproduction in rice community,emphasis being placed on the methodologyof modelling.The model consists of a main program and ten subroutines written inFORTRAN.The physiological processes of rice considered in the modelare CO2 assimilation,dry matter distribution among plant parts,leafexpansion,tiller formation and floral initiation.The values of importantvariables of rice stand(leaf area index,shoot number,and dry weightsof plant parts)are ca...
