Abstract
[Objective]To compare simulation effect of two kinds of rice growth model in Jiangxi Province.[Method] By the local field experimental observation data and meteorological data at the same period,the ORYZA2000 and WOFOST model parameters were compared.The growth period,the leaf area index and the biomass index were verified and evaluated.[Result]Measuring simulation effat of crop model with NRMSE,the biomass NRMSE value were less than 25% from ORYZA2000 model,and the NRMSE value of LAI and dry weight was 46% and 55% from WOFOST,which the deflection was larger.[Conclusion] Simulation effect of ORYZA2000 in spike biomass and leaf area index is better than that of WOFOST model.关键词
