摘要
介绍了水稻生长模拟模型ORYZA2000,并应用2002年水肥耦合试验资料,在水氮联合限制条件下对水稻生产模型ORYZA2000进行了参数校正,对模拟效果进行了图解分析和回归分析,结果表明,在水分平衡和氮素平衡条件下,ORYZA2000模拟水稻生物量、产量、氮素平衡以及田间水分平衡是可行的。该模型在水稻节水灌溉领域有很大的应用价值,为我国水稻节水灌溉向数字化发展提供了有利工具。
The paper introduced ORYZA2000 which simulates the growth and development of lowland rice. The model was validated and evaluated under water and nitrogen limited conditions against experimental data set of 2002. By graphical comparison and linear regression analysis of the simulation effect, we found that it was available for ORYZA2000 to simulate the biomass of organs, total biomass, final yield, LAI, nitrogen balance and water balance under water and nitrogen limited conditions. ORYZA2000 was of great significance in water saving irrigation for lowland rice, and was a favorable tool for the development of water saving irrigation of lowland rice from experiment to quantum.
