利用荆州市农业气象试验站2001年逐日气象观测数据和中稻生育期、生物量观测资料,对ORYZA2000作物参数进行校正,获取了丰两优1号的发育期速率、分配系数、比叶面积等基本作物参数,并利用2000年、2002年的观测数据和观测资料对模型适应性进行了检验.结果表明,ORYZA2000能够比较准确地模拟中稻的生物量、叶面积动态变化趋势及最终产量.%Based on the daily meteorological data and phonological and biomass data of middle rice in Jingzhou station in 2001, ORYZA2000 model was calibrated and validated. Some basic crop indexes such as developmental rates at different stages, partitioning factors of dry matter, specific leaf area of Fengliangyou No.1 were obtained. And then the adaptability of the model was verified using the experimental data in 2000 and 2002. The results showed that ORYZA2000 model could simulate the biomass, dynamic change trend of leaf area and yield of middle rice correctly.
