Study on Superior Tree Selection Methods of Phoebe Hui in Hunan

Abstract

Phoebe hui is a precious timber tree species. In order to get excellent seedlings and stands with good genes and develop Phoebe hui better, it is necessary to select superior trees. The dominant trees comparative method and small sample plot method were used to evaluate and select Phoebe hui superior trees in Longshan county, Hunan province, and the evaluation factors included diameter at breast height (DBH), tree height, timber volume and other quality factors. The results showed that, using the dominant trees comparative method, the DBH, tree height and timber volume values of the superior tree were more than 1.12, 1.06 and 1.23 times of the mean values of 5 dominant trees respectively, and 6 superior trees were selected in two stands. Using small sample plot method, the DBH, tree height and timber volume of the superior tree were more than the mean value and 1 times standard deviation value of the stand, and 4 trees were selected as superior tree. These 2 methods can be used for superior tree selection of Phoebe hui in Hunan, and the dominant trees comparative method is more simple and easier for operation.
