| 摘 要： | 对不同海拔人工林毛竹材纤维形态和化学成分进行测定和分析以揭示其变异规律。结果表明:海拔300 m人工林毛竹材纤维长度、长宽比和长纤维比率均大于海拔600 m和海拔900 m;海拔高度对人工林毛竹材纤维形态影响极显著;随着海拔高度的增加,毛竹材的热水抽出物含量、苯-醇抽出物含量、Klason木素含量及灰分含量均呈增大趋势,1%NaOH抽出物含量、纤维素含量及pH值均呈减小趋势。海拔300 m的毛竹材最适宜用作纸浆材。

| Abstract: | Fiber morphology and chemical composition of Phyllostachys heterocycla cv.pubescens plantation from different altitudes were determined and analyzed,and the variation regularities were revealed.The results showed that fiber length,the ratio of length to width and the ratio of long fiber of P.heterocycla cv.pubescens culm growing in the altitude of 300 m were bigger than those in the altitude of 600 m and 900 m.Altitude had extremely significant effects on fiber morphology of P.heter ocycla cv.pubescens Hot ... |
