| 摘 要： | ＯＲＹＺＡ－０模型系统能分析氮在土壤－作物－大气复杂系统中的复杂行为，包括土壤供氮力、作物氮吸收和氮在器官间的分配、叶片氮转化太阳辐射为干物质的能力等，ＯＲＹＺＡ－０模型与Ｐｒｉｃｅ的规则系统优化程序结合，可以制订取得最大生物量或经济产量所需的优化氮管理方案。田间氮试验材料验证模型表明，ＯＲＹＺＡ－０模型推荐的氮肥应用曲线能真实地反映当地不同氮水平下的氮管理策略；文中还就模型参数的敏感性问题和模型的进一步发展提出了建设性建议。

| Abstract: | This paper presents the theory of model ORYZA-0 foundation.The dynamic model integrates the knowledge about the soil and crop processes in order to quantify the behavior of N in the soil-crop-climate system,including the soil N supply and recovery,the N uptake,partitioning of N to leaf canopy, and the utilization of leaf N in converting daily incident global radiation to dry matter.When combined with the Price algorithm optimization procedure,ORYZA-0 model can de-rive the optimum N management strategies needed to achieve the maximum biomass or grain yield. One field nitrogen experimental dataset was used here to evaluate the ORYZA-0 model,and the computer N recommendation curve appears to be realistic. The useful comments and suggestions about the sensitivity of input parameters and the further development of the ORYZA-0 model are also been given in this paper. |
