密粘褶菌生物性降解对杉木木材性质的影响
Wood properties of Chinese-fir after biological degradation by Gloeophyllum trabeum (Pers.) Murrill
摘要
Abstract
In this research,we studied the effect of degradation time on chemical component,crystallinity,micro-mechanical properties,and micromorphology when using Gloeophyllum trabeum to degrade Chinese-fir.The result showed that Gloeophyllum trabeum did not degrade Chinese-fir's lignin.The mass fractions of ho1ocellulose,cellulose,and hemicellulose in sapwood decreased by 6.91％,4.07％,and 13.34％,and those in heartwood decreased by 6.84％,4.09％,and 12.97％ at the 6th week.After treated with wood rot fungi,the cellulose crystallinity,MOR,and MOE decreased and reached the minimum value at 18th week.The MOR and MOE of sapwood,and the MOR and MOE of the heartwood decreased by 46.17％ and 29.66％,53.74％ and 47.74％,respectively.关键词
