【摘要】 对云南甜竹的9项化学组成进行分析,结果表明:云南甜竹的综纤维素、木素等细胞壁主要物质含量和一般木材接近,灰分和各种抽出物含量介于木材和草类原料之间;除综纤维素和灰分在秆高方向上表现出明显的递增分布规律外,云南甜竹其它各化学成分在秆高方向上未呈现出明显的分布规律。从化学组成角度分析认为,云南甜竹满足制浆造纸工业对原材料的要求,可以作为发展竹浆产业的原料竹种,值得在气候适宜的地区推广种植。更多还原

【Abstract】 An experiment was carried out to study the chemical composition of Dendrocalamus brandisii. The results showed that the amount of the lignin and holocellulose contained in the D. brandisii stem was close to that in wood,the amount of ash and extractives was much more than that in wood and lower than that in grasses. Holocellulose and ash were distributed with an obvious increasing trend along the stem,but there was no such distribution trend for the other chemical compositions. With the analysis from the perspective of chemical composition,D. brandisii is a good fi ber material for papermaking industry.更多还原
