摘　　要：2011—2013年采用"3414"完全试验设计方案,对巴西蕉叶面积指数LAI及当地积温间的关系进行了分析,拟合出几种香蕉叶面积指数动态变化模型,其中以叶面积指数与归一化的相对积温间的动态模型较好,即:LAIi=3.653 2/[1+e-(RDDi-0.502 9/0.089 2)]。用2011—2013年独立资料进行检验,叶面积指数模拟值与实测值的平均绝对误差Χde为0.044 7,差值标准误Sde为0.211 5,相关系数R为0.927,达显著水平。表明所建模型可以较好地模拟巴西蕉叶面积指数的动态变化,也可用于巴西蕉生长、产量模拟以及对巴西蕉的生长监测和遥感估产。The relationship between leaf area index and accumulated temperature of banana cv. Bra- zil were studied using the ＂3414＂ completed experiment design during 2011 to 2013. The dynamic models of LAI for banana cv. Brazil, as well as the relationship between the effective accumulation temperature and LAI were studied. The results showed that better correlation between the LAI and relative effective accumulated temperature was LAIi= 3. 653 2/[1 ＋ e-（RDDI-0.5029/0.089 2 ]. Examina- tion results with the independent data of 2011-2013 showed that the mean absolute error and the standard error of simulated and observed LAI for banana cv. Brazil were 0. 044 7 and 0. 211 5 with a significant correlation coefficient of 0. 927. The LAI model of Brazil banana can simulate the dy- namic changes of Brazil banana LAI, also can be used for simulation and monitoring the growth of brazil banana and yield, and estimating yield by remote sensing.
