樺木屬本屬模式種

樺木地板優(yōu)點(diǎn)與缺點(diǎn)解析 樺木，一種灌木和喬木的統(tǒng)稱(chēng)。樺木的樹(shù)皮光滑平整，樹(shù)脂呈現(xiàn)乳白色，而樺木的木 材色澤呈現(xiàn)紅褐色，常用于地板、家具內(nèi)部裝飾材料、紙漿、家具、膠合板等制作應(yīng) 用，樺木生長(zhǎng)條件氣候比較偏寒冷，所以有著較好的耐寒性，對(duì)于病蟲(chóng)，有著意想不 到的免疫力，可想而知，由樺木材質(zhì)制作而成的樺木地板，想來(lái)應(yīng)該是也極好的。但 萬(wàn)物總有優(yōu)缺點(diǎn)，樺木地板亦是如此，本期小編就和大家一起探討一下關(guān)于樺木地板 的優(yōu)缺點(diǎn)吧！ 樺木地板優(yōu)點(diǎn) -容易加工在家居裝飾中，每一個(gè)過(guò)程都是繁復(fù)而負(fù)責(zé)的工程，哪個(gè)部位 該用什么裝飾，都是需要提前考慮好，就怕裝飾出來(lái)的家居效果達(dá)不到自己滿(mǎn)意的程 度。而最令人苦惱的就是家居地板的裝飾。中國(guó)地板市場(chǎng)多而復(fù)雜，魚(yú)龍混雜，令人 云里霧里，眼花繚亂，那么樺木地板怎么樣呢？樺木地板確實(shí)是很不錯(cuò)的，至少在加 工制作方面，沒(méi)有其他地板材質(zhì)的那么講究，所以加工容易，這是樺木地板中最特別

Four wood rot fungi were used to decay 300 mature trees of white birch in Liangshui experiment stations,and the mass loss of the samples was measured to study bio-degradability of the wood by the fungi. The decaying susceptible and resistant populations in 10 trees each with the highest and lowest mass loss were selected,in which some main chemical components in decayed and non-decayed wood such as lignin and cellulose and so on was tested. The result showed that the decomposing power of Coriolus versicolor to wood samples was better,and then were Fomes fomentarius,Irpex lacteus and Pholiota adiposa were poor. 1%NaOH extraction in decayed wood was significant higher than that in non-decayed control. Benzene-alcohol extraction in the wood decayed by Coriolus versicolor and Fomes fomentarius was significant higher than that in non-decayed control,but much lower than the control in the wood decayed by Irpex lacteus. The lignin decomposing rate by Irpex lacteus,Pholiota adipose and Fomes fomentarius were faster than the cellulose decomposing rate,the contrary result was achieved by Coriolus versicolor. This paper would provide some useful information in future study in the course and mechanism of wood decaying by rot fungi,and select engineering fungi for paper-making industry and pollution control.
