| 摘 要： | 在区域试验的基础上 ,分析大豆不同发育阶段的感温性与感光性的关系 ,构建了大豆发育期模拟模型。利用实际资料对大豆开花期和成熟期进行模拟检验。结果显示 ,模型误差一般小于 5 0d ,开花期和成熟期平均误差分别为 0 3d和 0 1d ,均方根差 (RMSE)约为 1 1d ,表明该模型可较好地模拟大豆的生长发育进程

| Abstract: | Based on regional experimental data and the analysis of relationship between soybean thermolsensitivity and photosensitivity,a simulation model of soybean development was developed in this paper.Then,the model was validated with experimental data.The results showed that the simulation errors were less than 5 d commonly,the average errors of flowering date and maturity date were 0.3 d and 0.1 d respectively and root mean square errors were about 1.1 d.All these indicated that the model was able to simulate soybean development well. |
