STUDY ON THE ADAPTABILITY OF RICE SIMULATION MODEL

Field experiments in different areas,at different seasons,under different fertilization schemes and under shading condition at different growth stages were conducted tovalidate the adaptability of Rice Simulation Model (RSM) The results show that the simulated values of RSM fit well with the measured values in dry matter accumulation, nutrient content,yield and its components regardless of the treatments The F values of the regression equations are highly significant The general trends of the simulated values fit well with the measured values The t values of both the regression intercept and coefficients are not significant,which indicate the simulated values fits well the measurements Yield components of the RSM fits well with the field data
