摘要
以3年生勃氏甜龙竹、龙竹、麻竹、泰竹、小叶龙竹与黄皮绿筋竹的竹叶与竹秆为研究对象,分析了6个竹种竹秆及竹叶中的灰分含量及二氧化硅含量。结果表明:6种竹材间无论是竹叶还是竹秆,其灰分含量及二氧化硅含量均存在明显差异,其原因可能为竹种及生长环境的差异所致;同一竹种竹叶中的灰分含量和二氧化硅含量大于竹秆中的含量;竹秆不同部位二氧化硅含量表现为自顶部至基部逐渐减小的变化趋势。
This paper analyzed the ash and silica content in leaves and culms of six 3 -year-old bamboo species, i. e.,Dendrocalamus brandisii,D. giganteus,D. latiflorus,Thyrsostachys siamensis, D. barbatus, Phyllostachys sulphurea（Carr. ） A. et C. Riv. cv. Robert Young. The results showed that ash content and silica content among the sixspecies had significant difference whether in leaves or in culms, which may be due to the difference in the species andgrowing environment. For the same species,the ash and silica contents in leaves were higher than those in culms. Thesilica content in different parts of a culm presented the decreasing trend from the top to the base.
