摘要
对广西融水县11个乡镇的毛竹竹材物理力学性质及竹材成分进行初步研究,结果表明:不同年龄毛竹的物理性能指标大小:6年生毛竹>4年生毛竹>2年生毛竹。2年生毛竹各物理指标不稳定,建议在采伐过程中保留,应首先选择6年生毛竹;融水毛竹材纤维素平均含量为40.67%,平均纤维长1.85 mm,平均纤维长宽比137.9,但与主要毛竹产区相比不占优势;综合比较,融水毛竹竹材强度高,弹性好,硬度大,适合加工各式竹制品。
The physical and mechanical properties and components of moso bamboo from 11 towns of Rongshui county,Guangxi were preliminaryly studied. The results showed that the physical performance of the 6-year-old bamboos was higher than that of the 4-year-old bamboos,while that of the 2-year-old bamboos was the lowest. The physical indexes of the 2-year-old bamboos were not stable enough. It is suggested that the 6-year-old bamboos should be cut first,while the 2-year-old ones be remained. The average cellulose content,fiber length and length width ratio of the moso mamboos grown in Rongshui were 40. 67%,1. 85 mm and137. 9 respectively,being inferior to that of the main bamboo production area. In general,the moso bamboos grown in Rongshui county showed high strength, good elasticity and high hardness,being suitable for processing various bamboo products.
