摘要：对浙江南部产的大木竹Bambusawenchouensis化学成分进行了分析,并与造纸性能良好的青皮竹Bambusatextilis和当地分布较广的水竹Bambusatextilisvar.fasca,绿竹Dendrocalamopsisoldhami等3个参试竹种及木本和草本制浆原料作了比较。结果表明,3年生大木竹竹材综纤维素质量分数为721.9g.kg-1,木素226.4g.kg-1,氢氧化钠抽出物251.3g.kg-1,苯-醇抽出物46.3g.kg-1。从造纸原料要求的标准讲,该竹综纤维素质量分数较高,木素与溶液抽出物较低或中等,属较好的造纸竹种。从年龄上看,1年生大木竹的综纤维素和多戊糖质量分数比3年生竹要大,而木素和灰分相对较少。
The chemical compositions of Bambusa wenchouensis wood in the southem area in Zhejiang Province were tested. Compared with those of three bamboo species: B. textilis, B. textilis var.fasca, Dendrocalamopsis oldhami, and other fibrous raw materials: tree wood and herbage, the results showed that the average content of holocellulose, lignin, 10 gkg^(-1) NaOH extractive and benzene-alcohol extractive was 721.9,226.4, 251.3 and 46.3 gkg^(-1) respectively. With the respect to the criteria required for pulpwood, the holocellulose content of B. wenchouensis wood was high comparatively, and the lignin and extractives were average or low, so it was one of superior pulping materials. The contents of holocellulose and pentosan in 1-year-old wood were higher than those in 3-year-old, but the contents of lignin and ash were lower relatively.[Ch,2 tab.12 ref.]
