Study on Dynamic Model of Leaf Area Index (LAI) for Banana (Musa AAA Cavendish subgroup cv.Brazil)
The relationship between leaf area index and accumulated temperature of banana cv.Brazil 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-0.502 9/0.089 2)].Examination 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 dynamic 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.
