摘　　要：根据江西南昌2012-2013年超级杂交早稻金优458的分期播种田间试验数据，调试ORYZA2000模型中的作物参数；利用调试后的作物模型模拟数据与整理后的田问试验观测数据，对超级杂交早稻发育期、地上生物量、穗生物量等进行回代检验和外推检验。结果表明：超级杂交早稻金优458开花期的模拟值与实测值相差1～3d，成熟期的模拟值与实测值相差0～3d；开花期、成熟期的地上生物量的平均误差分别为5．2％、3．3％，成熟期穗生物量的平均误差为2．0％；调试后的ORYZA2000作物模型可用于对超级杂交早稻的生长进行模拟，可为评价气象条件对超级杂交早稻发育期和生物量的影响提供定量化的技术方法。Field experiment observation data of super hybrid early rice, Jinyou 458 sowed at different times from 2012 to 2013 were employed to debug crop parameters in ORYZA2000 model. The simulated data debugged by the model and disposal data from field experiment observation were used to process the fitting test and extrapolation test for confirming the development period, total aboveground biomass and spike biomass of super hybrid early rice. The results showed that the differences between the simulated values and measured values of super hybrid early rice-Jinyou 458 in blossom period were 1-3 d, and the differences in mature period were 0-3 d. The average error of above ground total biomass in blossom period was 5.2%, and the average error in mature period was 3.3%. The average error of spike biomass in mature period was 2.0%. The debugged ORYZA2000 model could be used for the growth simulation of super hybrid early rice. The model offered a quantitative technical method for evaluating the impact of meteorological conditions on the growth and biomass of super hybrid early rice.
