广东地处热带、亚热带,盛产竹类,是丛生竹的主要产区。竹子纤维细长,长宽比值大,纤维组织比量高,是造纸的好原料。但竹类品种繁多,产量品质各异。研究竹子纤维形态,比较竹材品质的优劣,为造纸工业对原料的选择提供初步依据,有现实意义。一、材料与方法(一)试材采集本试验60种竹子均在广东林科所竹园内采集(详见表1)。每种竹子选取2—3年生竹3株,于秆高1.5—2m的节间中段截取竹环,并于竹环的相对方向取样,然后按实验要求分别制备试样。(二)切片试样切取宽约1cm、长约2.5cm 的竹片,水煮15—20h,投入酒精—甘油混合液中软化及保存,以备切片。切片染色后置显微镜下放大100倍,用面积法分 Guangdong is located in the tropical, subtropical, rich in bamboo, is the main producing areas of bamboo. Bamboo slender fiber, the ratio of length to width, high ratio of fibrous tissue, is a good raw material for papermaking. However, a wide variety of bamboo, yield and quality vary. Study of bamboo fiber morphology, bamboo quality comparison of the merits, for the paper industry to provide a preliminary basis for the choice of raw materials, and has practical significance. I. Materials and Methods (A) Specimen Collection 60 kinds of bamboo in this experiment were collected in a bamboo garden in Linke, Guangdong (see Table 1 for details). Take 3 - 3 - year - old bamboo for each type of bamboo, take the bamboo ring in the middle of internode with a height of 1.5-2m and sample it in the relative direction of the bamboo ring, and then prepare the sample according to the experimental requirements. (B) sliced ​​sample Cut a width of about 1cm, about 2.5cm in length bamboo, boiled 15-20h, put alcohol - glycerol mixture to soften and save for slicing. Slice stained magnified 100 times under a microscope, with the area method points
