| 摘 要： | 对Ｏｒｙｚａ－ｏ模型进行了修改，形成了一种根据不同水稻品种，土壤供氮特征和当地气候条件，优化施氮量和施氮时间的一种优化施氮系统（ＭＡＮＡＧＥ－Ｎ）。优化施氮系统的运行结果符合水稻产量形成对氮的需要，有较好的适应性。经多年试验示范表明，在同样施氮量的情况下，增产达１０％以上。

| Abstract: | Oryza-o was modified in this research. The new rice-nitrogen optimization system was formed, which can optimize the amount and timing of the N application according to the different rice cultivars, the characteristics of soil nitrogen supply and the local climate. The output of the rice-nitrogen optimization system fit the nitrogen needs of rice yield formation. Therefore the rice-nitrogen optimization system can be used as a tool for the recommendation of nitrogen application. The field experiment showed that grain yield could be increased by 10% at the same amount of nitrogen application. |
