摘要
毛竹材具有独特的化学成分和构造,在保存和加工利用过程中易受菌虫侵腐和破坏。本文通过对不同年龄、不同部位毛竹材在白腐菌和褐腐菌作用下的室内耐腐性能进行了研究,得出毛竹材的耐腐等级为Ⅱ或Ⅲ。毛竹材腐朽失重率随竹龄增大呈逐渐减小趋势,且幼竹在腐朽菌侵腐初期最易被侵腐,而6年生竹材侵腐初期耐腐性较其他好。白腐菌对毛竹材的致腐能力比褐腐菌强,对竹青致腐力小于褐腐菌,而两种腐朽菌对竹黄都有很强的致腐力。
The unique chemical composition and structure of bamboo led to it to be damaged invaded by rot and insect during the course of the process of preservation and processing. The natural durability properties of bamboo with different ages and sites those decayed by CV and GT were studied. It concluded that the natural durability grades of bamboo were Ⅱ or Ⅲ. The Weight loss ratio showed a decreasing trend with the age. Moreover, young bamboo was vulnerable to be invaded, while the natural durability of 6-year old bamboo was better than others in early decay processes. In addition, the decay capacity of CV to bamboo was much stronger than that of GT, while it was weaker to the outer layer than that of GT. Both of the two rots had strong decay capacity to the inner layers of bamboo.
