Abstract: In order to standardization of harvesting techniques for dwarf forest of Cinnamomum burmannii chvar. Borneol, the cutting and harvesting technology was studied in the 2-year-old young forest, 4 truncation heights were set, and 3 sub-branch processing modes were adopted to carry out each truncation height. Based on the analysis of three surveys in two years, results showed that there was no significant difference in background among four traits of tree height, ground diameter, crown width and steaming biomass. After treatment, the differences of four traits among different treatments were increased significantly, and all of them achieved very significant level. Multiple comparisons were also increased from 2 DUNNCAN groupings in the background to 3—4 groupings, and with the increase of truncation height, four trait indicators were gradually increased; the fewer retained branches, the four trait indicators were smaller. So the optimum processing combination was proposed that all branches of the trunk were retained after truncation at the height of 120 cm.

Key words: Cinnamomum burmannii chvar. Borneol, truncation height, pruning method, harvesting technology
