摘要： The ORYZA2000 rice model is currently the most versatile rice growth simulation model jointly developed by the International Rice Research Institute (IRRI) and the Wageningen University. In this paper, Jiangsu province, well known as land of plenty, was chosen as a study area to evaluate ORYZA2000 using datasets where the same (similar) varieties were grown under both direct sowing and transplanting conditions, in order to verify the capability and adaptability of model to reproduce the effect of different establishing methods on single-cropping rice growth and development in the middle region of Jiangsu province with the same calibrated parameter set. The field experiments were carried out in 2016. All the available observation data, collected at nine field experimental sites located in the middle region of Jiangsu province, was split into calibration and validation datasets. In the general, it is concluded that the ORYZA2000 model was adaptable and could be applied in scenarios analysis in Jiangsu province with the parameters adjustment and the model localization.
