Abstract

Analysis was made of the growth factors and correlation of diameter,tree height,height under branch and crown width of Schima superba in Huangmian Forest Farm in northern Guangxi. The results showed that,the diameter would not increase along with the increase of height under branch. Under the same diameter and different site conditions,the change of height under branch was similar to tree height. The growth of Schima superba at 660 metres above sea level was lower than the growth at elevations below 420 meters. Afforestation density had an obvious influence on the growth of Schima superba. Afforestation density of 2 m×2 m row spacing was suitable for Schima superba planting. Before platnting,some ways should be adopted to make trees grow well on the high ridge and the firebreak tree belt. Schima superba trees were apparently bifurcated in the process of naturally growing,thus some measures,such as thinning and pruning,should be taken to control the stand density.
