摘要:
研究南方红豆杉天然林木材的密度、胀缩性、吸水性和化学成分。结果表明:南方红豆杉天然林木材的基本密度为0.581 g·cm-3,气干密度为0.686 g·cm-3,体积干缩系数为0.390%,体积湿胀率为9.22%,60昼夜吸水性为95.8%,南方红豆杉边材的综纤维素、纤维素、聚戊糖、木素和灰分含量都比心材高,而抽出物含量远比心材低。南方红豆杉天然林木材是一种密度大、胀缩性小、吸水性低的优良木材。
Abstract:
Wood density, shrinkage and swelling, water absorption and chemical composition of Taxus chinensis var.mairei from natural forest have been studied in this paper. The results showed that the basic density was 0.581 g·cm-3, air-dried density was 0.686 g·cm-3, the coefficient of volume shrinkage was 0.390%, the percent of volume swelling was 9.22%, and the water absorption of 60 days and nights was 95.8%. In chemical composition, hollocellulose, cellulose, pentosan, lignin and ash content of sapwood were all higher than those of heartwood, while the extractive contents were far lower than that of heartwood. It indicated that T.chinensis was a sort of excellent wood with high density and low shrinkage-swelling and water absorption.
