摘要
以薄壁型巨龙竹为研究对象,对3～5年生薄壁型巨龙竹秆材的梢部、中部和基部进行物理性质研究。结果表明：薄壁型巨龙竹的基本密度、气干密度和全干密度分别为0.682 g/cm3、0.756 g/cm3、0.711 g/cm3,大于云南甜竹和油簕竹的相应值,略小于毛竹;吸水率为62.68%,显著高于毛竹的吸水率;径向气干干缩率为3.920%,大于毛竹相应值。就物理性质而言,薄壁型巨龙竹适合作为竹板材原料加以开发利用。
The physical properties of 3-5-year-old thin-culm-wall Dendrocalamus sinicus in tip, middle and base part were investigated. The results indicated that the basic density, air dry density, and oven-dry density of D. sinicus culm were 0.682 g/cm, 0.756 g/cm, and 0.711 g/cm, respectively, which were more than those ofD. brandisii, and slightly lower than that of Phyllostachys edulis. In addition, the saturated water absorption of D. sinicus culm was 62.68%, significantly higher than that ofPh. edulis. The radial air-dry shrinkage rate was 3.920%, more than that ofPh. edulis. Therefore, the culm of thin-culm-wall D. sinicus is suitable for processing as the material for manmade board.
