Preliminary Study on Early Growth Rhythm of Phoebe hungmaoensis Plantation Base on Stem Analysis
The growth of Phoebe hungmaoensis plantation was analyzed by the stem analysis. The results showed that the 9-year-old tree grew fast and straight, but it was immature. From the perspective of growth rhythm, the current annual increment of P. hungmaoensis DBH showed a decreasing trend decreasing year by year, and the current annual increment of tree height showed a wave-like decreasing trend. The current annual increment and the average annual growth rate of volume presented the increasing trend year by year. The current annual increment of height, DBH and volume and diameter-height form factor was decreased with the increase of the tree age, which showed the descending trend of the first rapid and then slow. The young trees of P. hungmaoensis had a certain shade resistance and could grow faster under the canopy.
