油菜发育动态模拟模型
A PHENOLOGICAL MODEL TO SIMULATE RAPE DEVELOPMENT
-
摘要: 根据油菜生理生态理论及油菜阶段发育与环境因子之间的数量关系，在借鉴WCSODS小麦“钟模型”与CERES-Wheat春化模型的基础上，构建了油菜发育动态模拟模型。利用在江淮地区广泛收集到的油菜发育期资料，分别调试、确定了2种不同品种类型有代表性品种的发育参数，并将模拟结果与积温法进行了比较。结果表明：本文提交的模型对不同生育阶段的模拟平均误差在1 d之内，对全生育期的模拟绝对误差平均不超过2 d。其模拟精度要明显好于传统的积温法。Abstract: A dynamic simulation model for rape phenological development is established according to rape physiological and ecological theories and the quantitative relationship between rape phenological development and the environmental factors. The "wheat clock model" in WCSODS and the vernalization model in CERES-wheat are used for reference. A three-year experimental data set is partially used for modification and determination of the genetic parameters for 2 cultivars and partially for validation of the model. The simulated errors are the compared with the accumulated temperature method. The results show that the average errors are within 1 day for different development period, and the standard errors are within 2 days for whole developmental duration.
