| Research Abstract |
Larch is an intolerant tree species for shade and it is necessary to expose the sunlight for its growth. If the interval among tree could cotrol with the tree grows,the competition my be ease. In order to accelete the diameter growth of the tree,we should not have inhibite the growth of the crown. Good quality of the lignum way result from continuing the homogeneous growth which the growth fluctuates leaser. Homogenious lignum will mainly obtaine from the lerge diameter tree and it is efficient for utilization of trees.
