中文摘要：
通过田间实验,对模拟水稻生长的作物生长模型ORYZA2000的参数进行了校正。然后,应用ORYZA2000模型对不同施N水平下水稻的生物量、产量及地上部分吸N量进行了模拟。结果表明,生物量、产量及吸N量的模拟值和实测值均呈明显的正相关,相关系数分别为0.9638、0.9511和0.8791,模型较好地模拟了水稻的生物量和产量。但是,在穗分化-抽穗期地上部分吸N量的模拟结果欠佳,需要进一步改进。
英文摘要：
Based on the experiment data, calibration of ORYZA2000 model was done for simulation of rice growth. Then, the model was used to simulate biomass, yields and nitrogen uptake of rice. Results showed that the simulated values were in significantly linear correlation with the measured ones with coefficients R2 lacing 0.9638, 0.9511 and 0.8791, respectively. The modeling results showed reasonable fitness with the measured ones in biomass and yield. However, the simulation of nitrogen uptake by rice was not good enough, especially during the panicle formation phase, and more research needed to be done.
