生长空间对人工林红松建筑材材质的影响

对不同生长空间（修枝与未修枝）的人工林红松（Pinus koraisensis)建筑材材质进行测试和分析，结果表明：木材的纤丝角、生长轮密度、生长速率、生长轮宽度和绝大多数力学性质指标差异不显著。木材的晚材率、抗弯强度和抗拉强度差异显著。采用综合坐标法，对不同生长空间（修枝与未修枝）的林分建筑材材质评定结果为生长空间较大的林分好于生长空间较小的林分。因此，适宜的生长空间可以提高林木材质。

The Effect of Growth Space on Structural Wood Quality of Pinus koraiensis Plantation

Wood qualities of Pinus koraiensis plantation from different space (pruning and non-pruning) plantation have been measured and analyzed, the results showed that their variances of fibril angle, growthring density, growth rate, growthring width and many mechanical properties are not remarkable; those of late wood percentage, static bending strength and tensile strength are remarkable. By comprehensive coordinates, the wood qualities in pruning and non-pruning plantation were evaluated, and comprehensive structural wood quality from pruning plantation are better.
