摘　　要：为建立小白菜器官生长动态模型,以小白菜品种‘春油5号’为试验材料,在温室环境内测定环境温度数据以及小白菜的株高、叶数、叶面积、茎粗、根长和鲜重,建立基于有效积温的小白菜器官生长模拟模型,并利用分期试验数据对模型进行检验。结果表明:小白菜株高、叶数、叶面积、茎粗与平均有效积温表现为二项式关系,根长、鲜重与平均有效积温表现为三项式关系。模拟模型对小白菜株高、叶数、叶面积、茎粗、根长和鲜重的相对预测误差RE较小,分别为5.00%、3.90%、7.66%、9.42%、2.83%和8.42%,表明模型的预测精度较高。模拟模型的模拟值与实测值之间的相关系数r均较高,分别为0.983、0.992、0.993、0.986、0.997和0.994,表明两者之间吻合度较好。基于积温法建立的模型可为小白菜器官生长动态模拟提供参考。In order to establish a dynamic model of organ growth of non-heading Chinese cabbage,a nonheading Chinese cabbage variety‘Chunyou 5’was used as experimental material.The environmental temperature data,plant height,leaf number,leaf area,stem diameter,root length and fresh weight of the variety were measured in a greenhouse environment.The organ growth simulation model of non-heading Chinese cabbage based on effective accumulated temperature was established,and the model was tested with experimental data of another period.The results showed that plant height,leaf number,leaf area,stem diameter of non-heading Chinese cabbage and average effective accumulated temperature showed binomial relationship,while root length,fresh weight and average effective accumulated temperature showed a trinomial relationship.The relative prediction errors of plant height,leaf number,leaf area,stem diameter,root length and fresh weight of non-heading Chinese cabbage were small,which were 5.00%,3.90%,7.66%,9.42%,2.83%and 8.42%,respectively,indicating that the prediction accuracy of the model was high.The correlation coefficients between the simulated values and the measured values were high,which were 0.983,0.992,0.993,0.986,0.997 and 0.994,respectively,indicating a good agreement between them.The model established based on accumulated temperature method could provide reference for the dynamic simulation of organ growth of non-heading Chinese cabbage.
