摘　　要：用不同的生长模型拟合玉米的生长发育数据。结果表明,Gompertz模型能较好地描述玉米总叶片数随有效积温变化的动态;Logistic模型能较好地描述玉米总面积和玉米株高的发展变化动态。根据上述模型得到玉米叶面积相对日增量随有效积温发展变化的三参数高斯模型:y=3.505 4EXP{-0.5[(x-1111.485 4)/256.095 2]2}(R2=0.994 4)Several models were used to simutate the temporal data of maize growth. The results showd that Gompertz model and Logistic model could reflect respectively the change of the total leaves number and the total area and height of maize with time. According to the above models, the relative leaf area increasing per day with the development of effective temperature could be expressed by the Gaussian model： y=3.505 4EXP {-0.5 [ （x-1 111.485 4）/256.095 2]^2}. The above models provided an important foundation in disease epidemiology.
