| 摘 要： | 利用在湖北省房县所开展的两年（2012、2013年）田间试验，对水稻品种宜香3728在CERES-Rice模型中的遗传特性参数进行了调试与校验。首先，根据2013年田间实测数据，如关键生育期及其叶面积指数、地上部干物质量和产量等，采用“GLUE+试差法”对宜香3728的遗传特性参数进行了调试。当达到设定的误差控制标准时（10%以内），停止调试，并将此时模型中的遗传特性参数作为调试结果。然后，再应用2012年实测数据对此组遗传特性参数进行校验。模型模拟值与田间实测值之间的对比关系表明此组遗传特性参数基本准确，可用于表征宜香3728水稻品种在房县的遗传特性。研究成果为利用CERES-Rice模型在房县及周边同类地区开展相关研究工作奠定了基础，同时也可为CERES-Rice模型在其他地区的本地化应用提供借鉴。

| Abstract: | According to field experimental data in two years（2012 and 2013）in Fangxian of Hubei province，genetic parameters of Yixiang 3728 in CERES-Rice model were adjusted and validated.Firstly，experimental data in 2013 such as dates of key growth periods，leaf area index，dry weight of aboveground biomass and grain yield，were used to adjust these parameters with GLUE program and trial and error method.When error standard reached（most lower than 10%），adjustment was ceased and corresponding genetic parameters were finally determined for Yixiang 3728.After that，experimental data in 2012 were used to validate these determined genetic parameters.Agreement between simulated to measured data in 2012 indicated that these determined parameters were reliable and could be used to reflect genetic characteristics of Yixiang 3728 in Fangxian.These results obtained in this study laid a substantial foundation for other studies related with CERES-Rice model in Fangxian or some other similar regions，and could be also further referred for localization of CERES-Rice model in other regions. |
