THE GROWTH AND PERFORMANCE OF EXPERIMENTAL SCOTS PINE PLANTATIONS WITH DIFFERENT DENSITY

O.V. Zhukovskyi

Abstract


Here we have the conclusion of learning the influence of the forest stand's density on the base of forest inventory indices by 38 years plantations of Scots pine. In the process of the research is settled, that the average diameter of forest stand on the sections with different its density are differ from the control on 5-10 %, the average on 5-8 %. The biggest different is observing in a growing stock of the forest stand, so as it is stand between sections and control – 9-18 %. It is done the conviction that the density of the forest stand saves the enough influence on the forest inventory indices through 38 years. The materials of the research point on standing trees 4000 trees·ha-1 no matter of the way tending felling is the optimal density of the forest stand for getting the top growing stocks of the forest stand.
