Abstract:

For different silvicultural measures(forest composioin,planning densiy,thinning and pruning), the mechanical properties of Pinus koraiensis plantations were measured and analyzed. The results showed that the effect of silvicultural measures(forest composioin,planning densiy,thinning) on mechanical properties(bending strength,crushing strength along the grain,tensil strength along the grain) of P. koraiensis plantations were remarkable,other strength and all strength of the pruning forest were not remarkable.In order to increase the mechanical properties of wood, growth-promoting and then get the better building lumber and glued lamination board, mixed stand, and with density of 1.5 m×1.5 m and 1.5 m×2.0 m, properly thinning and pruning could be selected. In order to manufacture furniture and bending-wood, density of 2.0 m×2.0 m could be selected.
