补充资料:造材
      按木材规格要求,将原条截成原木的作业。实行原木运材时,在伐区进行;实行原条集材或伐倒木集材时,在山上楞场或贮木场进行。
  
  由于立地条件不同,林木的形状、材质各不相同,甚至同一株树的不同部位,其形状、材质也各异。因此应根据每株树的缺陷,如腐朽、裂纹、弯曲、尖削和节子等的有无或分布情况,尽可能造出较多的优质材,以提高木材的造材率和等级率。
  
  造材前,量尺员先对原条进行观测,然后根据国家原木标准,树、材种生产计划、市场需求和原条上的缺陷进行量尺,并标记出下锯记号。量尺员技术水平的高低对造材率和等级率有明显的影响。
  
  造材时,下锯方向要与树干轴线垂直,并防止劈裂。伐区造材的作业条件和安全性差,造材质量较低;贮木场造材有专门的造材台,作业条件较好,造材质量有保证。伐区的造材工具主要是油锯和手工据。中国在贮木场造材多用电动链锯。
  
  20世纪50年代末以来,苏联等国家首先在贮木场采用固定式圆锯机和链锯机进行原条造材。70年代后,瑞典和芬兰等国制造了在林内和运材道旁作业的自行式打枝造材机,用液压驱动链锯或圆锯。这类机械往往是多工序联合作业机(见彩图)。造材机构中的进料、量尺和锯切等装置由电脑控制,生产效率高,量尺准确,作业安全,但不能按原条各部位质量区别下锯,多用于针叶树材及造纸材的生产。
