| 摘 要： | <正>用土壤木块法测定Ⅰ-69杨木(Populus deltoides Bartr.var deltoides cv Lux)的天然耐腐力,试验表明,属于不耐腐朽的树种。在受白腐菌(彩绒革盖菌Coriolus vecrsicolor)和褐腐菌(密粘褶菌Cloeophllum trabeum)腐朽9周后,木材的重量损失率分别为51.72％和71.55％。通过扫描电子显微镜观察,揭示了两种腐朽菌分解木材细胞壁的过程。为提高Ⅰ—69杨的抗腐性,使用6种防腐剂,均有效果,尤其是铜-铬-硼配方效果最好。

| Abstract: | Natural decay resistance of Popu lus delioidcs Bartr. Var delloides cv. 'Lux' is determined by soil-bloek method. The test results show that weight loss percentage of this species of wood attached by Coriolus versi color and Gloeop-hllum trabeum arc 51.72% and 71.55% after 9 weeks, respectively, belonging to "non-resistant" species. By observing the hyphal distribution and the penetration in wood cells and microstructural changes of cell walls, the process of degradation of wood cell walls are revealed.In order to improve the decay reistance of the specie of wood, 6 types of wood preservatives are treated at various retention, so that the decay resistance of treated wood are all improved. In particular, CCB (Chromated Copper Borate) is of great effectiveness. Decay resistance of tJeated wood can reach up to the grade of very resistant wood. |
