Although Papua New Guinea (PNG) has a rich and diverse forest cover, there is limited information on processing characteristics for plantations and regrowth forests available. Consequently, the PNG timber processing industry is restricted to a few species, producing low-quality products, which limits opportunities for the processors. Sound knowledge of machining characteristics based on some systematic methods has been identified as essential for assessing the ability in processing raw material into appearance products. Therefore, a testing program was conducted to assess the planing characteristics and most common causes for planing degrade of 25 species sourced from the Morobe and West New Britain provinces, PNG. A total of 18 wood species proved to machine very well with more than 90% of assessed boards being graded either “excellent and requiring very light sanding” or “good and requiring light sanding”. Eight species from this group obtained a perfect score, i.e. requiring very light sanding.

来自人工林和再生林的巴布亚新几内亚木材物种的平面特征

尽管巴布亚新几内亚（PNG）拥有丰富多样的森林，但有关人工林和再生林的加工特性的信息有限。因此，PNG木材加工行业仅限于少数几种，生产的产品质量低下，这限制了加工者的机会。基于一些系统方法的良好加工特征知识已被认为对评估将原材料加工成外观产品的能力至关重要。因此，进行了一项测试计划，以评估来自莫罗贝和西新不列颠省PNG的25种物种的刨光特征和造成刨光退化的最常见原因。事实证明，共有18种木材能够很好地加工，其中90％以上的评估板被评定为“优秀且要求非常轻的砂光”或“良好且需要良好的砂光”。该组中的八种获得了满分，即需要非常轻的打磨。
