摘要
就贵州省赤水市料慈竹（Ｂａｍｂｕｓａｄｉｓｔｅｇｕｓ）０～４ａ５个龄级的纤维形态进行显微观测和系统分析表明，其纤维长度为２．１３～２．６９ｍｍ（平均２．４５ｍｍ），纤维宽度为１３．４２～１５．０６μｍ（平均１４．０９μｍ），长宽比历８～１８５（平均１７４），壁厚２．５２～６．４６μｍ平均４．８６μｍ），腔径２．１５～８．３９μｍ（平均４．４１μｍ），壁腔比为０．６～６．１７（平均３．２４）。通过方差分析后表明，除纤维长度和宽度外，年龄对料慈竹纤维形态有一定影响，表现在纤维壁厚度上，从０～１ａ有增厚，１ａ后相对稳定，至４ａ时明显增厚；纤维腔径相反，从０～１ａ腔径减小，至４ａ时明显减小。
Microscopic observation and systematic analysis on the fiber morphology of Bambusa distegus-one of the main raw materials of papermaking in Chishui,Guizhou. province.showed that the fiber length(L) varied from 2.13 mm to 2.69 mm,the average was 2.45mm.Its width(W) was between 13.42μm and 15.06μm,the averagewas 14.09μm.The ratio of length and width (L/W) was from 158to 185.Fiber tell thickness(T) ranged from 2.52μm to 6.46μm,the cavity diameter(D) was from 2.15μm to 8.39μm,thus,T/D varied from 0.6 to 6.17. Variace analysis indicated that age had influence on the fiber morphology-the fiber length,and cell thickness increased while the cavity diameter decreased as the bamboo grew up.
