| 摘 要： | 以通蓖9号、通蓖6号、通蓖5号和中东为试验材料,利用作物生理发育时间恒定的原理,系统构建了蓖麻花芽分化和物候期的机理模型。模型用Bate函数来计算相对热效应,用高斯函数来计算光周期效应,引入温度敏感性、光周期敏感性、品种早熟性和灌浆因子4个参数。运用不同地点和年份试验数据对模型进行检验,结果表明：不同品种蓖麻生长锥伸长膨大期、花梗原基分化期、小花原基分化期、花粉粒和子房形成期、花粉粒充实完成期等花芽分化阶段和出苗期、开花期、结果期和成熟期等物候期的绝对模拟误差0~5d,根均方差不超过3d。

| Abstract: | Four castor cultivars, Tongbi 5, Tongbi 6, Tongbi 9 and Zhongdong were used to construct the mechanism model of flower bud differentiation development stages and phenophase in castor, based on the principle of crop physiological development time constancy. Temperature sensitivity, photoperiod sensitivity, intrinsic earliness and filling factors were used in the model. The relative thermal effectiveness was calculated by Bate function and photoperiod effectiveness was calculated by Gauss function. The model was examined in different years and sites. The results showed that absolute errors of flower bud differentiation development stages and phenophase were 0 -5d, and root mean square error was fewer than 3d. |
