在2005－2006年盆栽试验基础上，系统分析了生态因子对棉花主茎叶、果枝叶和主茎节间、果节形态发生的影响，量化了温度、氮素、水分、化控（DPC）等与棉花各器官形态建成的关系，构建了基于有效积温（GDD）、以Logistic模型为基础的棉花主茎和果枝的叶片长度、宽度、叶柄长度及主茎节间、果节长度和粗度形态发生的动态模型。利用不同氮素水平、不同品种、水分、化控试验资料对模型进行了检验。结果表明，棉花主茎和果枝的叶片长度和宽度、叶柄长度及主茎节间、果节长度和粗度的模拟值与观察值之间均方差根（RMSE）分别为0.66 cm、0.87 cm、0.77 cm、0.57 cm、0.77 mm、0.43 cm、0.55 cm、0.43 cm、0.73 cm、0.56 mm,棉花器官形态发生的模拟值与观测值具有较好的吻合度，说明模型具有较好的预测性和准确性
Abstract
Based on the potted plant research in 2005－2006, the effects of ecotypic factors on the length of internode of main stem, the length of fruit node, the shape of main stem leaf and sympodial leaf were analyzed. The effects of temperature, nitrogen, water and DPC were quantitied on each organ's development. The physiological dynamic simulation model of the length and width of leaves of main stem and fruit branch, the length of leafstalk of main stem, internode of main stem and the length and thickness of fruit node were constructed based on GDD and Logistic model. The model was validated by the data from different nitrogen input levels and varieties, RMSE between simulated and observed values of the length and width of main stem leaves and sympodial leaves, the length of main stem leafstalk, the length of main stem internode and the length and diameter of fruit node were 0.66 cm, 0.87 cm, 0.77 cm, 0.57 cm, 0.77 mm, 0.43 cm, 0.55 cm, 0.43 cm, 0.73 cm, 0.56 mm. The simulated and observed values were inosculated well, which indicated that the prediction veracity of this model was good.
