摘要：以材性优良的毛竹等竹种为参比,研究了丛生竹种大木竹竹材的物理性能。结果表明:大木竹竹材的基本密度为0.618 g/cm3,小于毛竹的基本密度(0.765 g/cm3),而比参比的其他丛生竹密度大或与之相当;大木竹竹材气干体积干缩率为7.7%,吸水饱和体积湿胀率为18.686%,饱湿含水率为77.8%,均大于毛竹材的相应值。
The wood physical properties of Bambusa wenchouensis were studied and compared with those of other bamboos including Phyllostachys edulis. The result showed that the basic density of B. zverrchouensis was 0. 618 g/cm^3 , lower than that of P. edulis （0. 765 g/cm^3） and equal to or higher than that of other sympodial bamboo species. The air dry volume shrinkage ratio was 7.7%, the maximal swelling ratio was 18. 686%, and the maximal water absorption ratio was 77.8%, which were all higher than those of P. edulis.
