摘    要:
木材天然耐腐性是木材本身固有的抗腐朽能力,各种树种的耐腐性不尽相同,它与木材特性组织结构及其内含物的化学成分有关。从木材利用的要求来说,希望木材具有良好的耐腐性能,经久耐用。但各种木材的天然耐腐性很不一致,为了合理利用我国森林资源,在木材利用上既可考虑选用耐腐树种,也可对不耐腐树种的木材进行必宴的防腐处理,以增强木材的耐腐性,延长木材使用年限。做到合理利用木材和培植优质耐腐树种。尤其在当前我国四个现代化的建设中,木材需用量激增,但在我国森林资源不足的情况下,对于木材耐腐性的试验研究,是迫切需要解决的课题之一,同时,也可为我国生产、科研、教学提供必要的科学依据。本试验选用161种树种木材进行了室内天然耐腐性试验。为了得到比较完善的结果,对部分树种的木材还进行了不同木腐菌(包括白腐菌与褐腐菌)的耐腐性比较试验。

Abstract:
Natural decay resistance of 161 Chinese timber species (136 hardwood species and 25 softwood species) against white rot fungus, Polyporus versicolor Fr. and brown rot fungus, Lenzites trabea Pers. ex Fr., was determined by sand-block method in laboratory. The classes of their natural decay resistance can be arranged as follows:Cryptmaeria fortunei, Cupressus funebris, Fokienia hodginsii, Larix gmelinii, Castanopsis hystrix, Cyclobalanopsis chungii, Homalium hainanenses, Madhuca haiannensis, Quercus chenii, etc. are designated as class of very durable.Ketelecria fortunei, Pinus yunnanensis, Tsuga dumosa, Albizzia julibrissin, Juglans mandshurica, Querous nongnolica, etc. are classi-fied as durable class.Picea koraiensis, Ailanthus altissima, Albizsia falcata, Betula alnoides, Camptotheca acuminata, Casuarina equisetifolia, etc. are classified as moderately durable class.Picea jezoensis, Alniphyllum fortunei, Castanopsis carlesii, Liquidambar formosana, Populus davidiana, etc. are classified as perishable class.From the results obtained here, the specimens weight losses caused by brown rot fungus (Lonsites trabea) appeared lower than those by White rot fungus (Polyporus versicolor).
