珍稀及待开发树种材性及用途的研究

选择了大别山五针松、杉松、三角枫、山核桃，梓树、朴树、连香树、毛，丝棉木，刺揪，铜钱树，棠梨、琅琊榆，醉翁榆及榔榆等１５个树种，观察和记载木材解剖特征，分析其化学成分，测试物理性质，力学性质以及加工性质。根据上述各树种的材质、材性和加工性质，大别山五针松、山核桃、梓树、连香树，琅琊榆，醉翁榆及榔榆等木材优良，应属于稀有和珍贵的木材树种。杉松、三角枫、朴树、毛、丝棉木、刺揪、铜钱树及棠梨等木材质量好，价值高，可以有计划的发展作为重要的商品材开发利用。本文还根据各树种木材的特性，结合实际调查，提出这些树种木材的合理加工和利用的意见。

Timber Qualities and Uses of Rare Wood Species and Trees to Be Developed

s Fifteen tree species were selected as testing materials,including Dabieshan soft pine,Fir pne,Ya maple, Chinese hickory,Chinese catalpa,Katsura,Chinese hackberry,Pubescent dogwood,Silk euonymus,Castor aralia,Copper cash thorn, Tang pear,Zuiweng elm , Langya elm andChinese elm. Their anatomic features of wood have been described. The principal components havebeen obtained by chemical analysis, the physical and mechanical properties of timber have beendetermined,and during making wood samples,the processing characters were observed.According to wood qualities obtained,Dabeishan soft pine,Chinese hickory,Chinese catalpa,Katsura,Zuiweng elm,Langya elm and Chinese elm should be belonged to rare and valuable treetimber species and the others Could be developed as principal and valuable commercial timbers. Based on special characteristics of the tree species in connection with production practice,suitiable processing and best utilization has been systematically proposed in the present paper.
