摘要
对20世纪80年代以来引到大老岭林场的北美、西欧、日本原产种工业用针叶树的原料化学组成、纤维形态、糖类组成等进行了分析。研究表明,欧洲云杉的冷水、热水抽出物、碱抽出物和有机溶剂抽出物均较低。综纤维素含量相对较高,而木素含量较其他材种低。而且欧洲云杉的平均纤维长度较高,纤维的长宽比也较大,这些特性对于制浆造纸是有利的。
An analysis of wood chemical compositions,fiber form and saccharine compositions was carried out for industrial-wood conifers, which were introduced to Dalaoling forest farm of Yichang of Hubei province in 1980'from North America, West European and Japan.The result showed that the hot, cold water extractions, alkaline and organic solvent extractions of Picea abies were low, and the total cellulose contents of Picea abies were high relatively. The contents of lignin of Picea abies were less than the others conifers. The average fibre length and fibre ratio of Picea abies were relatively high.These traits of Picea abies were good for pulpwood and papermaking.
