Study on Growth Regularity of Choerospondias axillaris Plantation

YU Mengyang;Qingliu National Forset Farm of Fujian Province;  
This text took a study on the growth law of Choerospondias axillaris plantation in Qingliu National Forset Farm of Fujian province in 2015.The results of the study showed that the tree height of Choerospondias axillaris had two fast growth period,that was respectively in the 5th~11th year and the 26th~32th year.Successive growth showed a maximum peak at the 10th year.The fast growth stage of DBH and volume of Choerospondias axillaris was in 39 years ago.By fitting the growth process of Choerospondias axillaris,the conic model had the best effect in fitting the growth process of DBH of Choerospondias axillaris.The correlation coefficient and the sum of squared residuals were 0.9975 and 0.8026.The optimal growth model of DBH is y=-0.172414 +0.358276 t+0.004630 t~2.The Weibull model had the best effect in fitting the growth process of tree height of Choerospondias axillaris.The correlation coefficient and the sum of squared residuals were 0.9855 and 2.0953.The optimal growth model of tree height is y=17.4549[1-e~(-(t+27.0183/50.5605)~(3.2225))].The Weibull model had the best effect in fitting the growth process of individual volume of Choerospondias axillaris.The correlation coefficient and the sum of squared residuals were 0.9993 and 0.00005.The optimal growth model of individual volume is y=1366.6113[1-e~((t+7.5713/374.5885)~(4.1374))].
