中文摘要 | 本文目的在瞭解疏伐及修枝作業對針葉樹材性質的影響,回顧有關不同疏伐及修枝處理對材質影響之文獻資料,討論包括木材比重、生長輪、管胞長度、晚材率、枝節性及動彈係數等木材性質之變異性,以作為將來育林措施及訂定林產工業目標決策時之參考準則。 |
英文摘要 | The objective of this paper is to clarify what changes in softwood properties would be resulted from various thinning and pruning treatments. Some of the many studies related to the thinning and pruning effects on wood properties have been reviewed. Variation of some wood properties, viz., specific gravity, growth ring width, tracheid length, latewood percentage, knots, ultrasonic wave properties and so on were discussed. The wood properties and traits from plantations treated with tinning and pruning practices provided some important information for future management and wood utilization of the some plantation species. |
