云南木竹材材质的研究现状

Current Situations Research on Wood and Bamboo Qualities in Yunnan

对人工林木材材质的研究是一个热点,木材的材质直接影响到加工利用,思茅松、巨桉、龙竹和西南桦是我省主要的人工林树种。本文综述云南木竹材(思茅松、巨桉、龙竹和西南桦)的研究现状,培育措施(包括不同造林密度、抚育间伐)和立地条件对木材材质的影响,并指出纤维形态、综纤维素、木质素、戊聚糖、1%NaOH抽出物、苯醇抽出物、生长轮宽度、晚材率、基本密度等影响纸浆材材质的主要性能指标。

Research on plantation wood qualities is a hotspot. Wood qualities are directly affected wood process and utilized. And in Yunnan province, Pinus kesiya var. langbianensis, Eucalyptus grandis, Dendrocalamus giganteus Munro and Betula alnoides are primary plantation tree. The paper is summaried the research status quo of wood and bamboo （Pinus kesiya var. langbianensis, Eucalyptus grandis, Dendrocalamus giganteus Munro and Betula alnoides） in Yunnan. The effect of wood qualities are silvicultural measures （included plantation density.thinning and so on） and site conditions, and pointed out that fiber shape, holocellulose, lignin, pentosan, 1%NaOH extraction, alcohol--benzene extract, width of growth ring, latewood rate and basic density also influenced mostly performance index of pulpwood.
