以广西壮族自治区4种丛生竹:撑篙竹、花吊丝竹、粉单竹和马蹄竹为研究对象,探索其横切面维管束分布特征以及主要物理力学特性。结果表明,粉单竹维管束分布较为紧密,维管束密度最大,撑篙竹、花吊丝竹维管束分布较为分散,马蹄竹维管束密度最小;粉单竹的基本密度、气干密度和全干密度,以及力学特性在4种丛生竹中最大,其次是花吊丝竹,撑篙竹与马蹄竹物理力学特性相近。研究发现,粉单竹材性最好,可进行工业化加工利用,花吊丝竹、撑篙竹及马蹄竹可分离出竹青部分再进行高效加工利用。
In order to explore the distribution characteristics of the vascular bundles in cross section and the main physical and mechanical characteristics, four species of Brachyceps bamboos: Stipa bungeana, Halophyte spp., Sogatella mandshurica and Himalayan Bombay were studied in Guangxi Zhuang Autonomous Region. The results showed that the distribution of vascular bundles was close and the vascular bundle density was the largest. The distribution of bamboo vascular bundles in Brachypodium distachhioides and Diao filaments was dispersed and the vascular bundle density was the smallest. The basic density, air-dry density and dry- Density, and mechanical properties of the four kinds of clustered bamboo largest, followed by the hanging wire bamboo, bamboo and bamboo horseshoe bamboo physical and mechanical properties similar. The study found that the best powder single bamboo can be used for industrial processing and utilization, spend hanging wire bamboo, bamboo and bamboo Horseshoe Bamboo can be separated after the bamboo part of the efficient processing and utilization.
