摘要
对修枝与未修枝的红松人工林林木生长和木材力学性质等指标进行测试和分析 ,结果表明 :红松人工林生长速率、生长轮宽度、晚材率都是修枝林分大于未修枝林分 ,其中只有晚材率差异显著 ;主要力学指标中除顺纹抗压强度 ,均是修枝林分大于未修枝林分 。
The trees growth and wood qualities of Pinus koraiensis plantations for pruning and no pruning were measured and analyzed. The results showed that the growth rate, growth-ring width and late wood percentage are higher for the pruning stand. Among them only late wood percentage is remarkable. The crushing strength along the grain is higher for the no pruning stand, the other mechanical properties are higher for the pruning stand. And only the bending strength is remarkable.
