摘  要：
为做到适材适用、全面提高棕榈藤材的高附加值加工利用水平,以黄藤材为研究对象,采用生物解剖方法,从藤茎基部到梢部,对黄藤材导管、纤维形态特征等进行了系统测试,分析棕榈藤材藤龄与结构的关系,并对棕榈藤材藤龄进行了判断。结果表明:以黄藤材纤维长度、双壁厚和导管密度的乘积为分子,纤维宽度(直径)、导管直径的乘积为分母的综合判别因子Ra绘制曲线,则曲线上谷值对应的是早材,而峰值对应的是晚材,即曲线上有一个突然下降的变化趋势线段,即为1 a分界。

摘  要：
In order to adapt to the application and to improve the level of high value-added processing and utilization of rattan material,Daemonorops margaritae was chosen as the research object and its morphological characteristics of vessel and fiber were determined systematically with biological methods from the base to the tip of the rattan.The relationship between the age and the structure of the rattan was also explored to realize the rattan age.The numerator is the product of fiber length,double-wall thickness and vessel density,the denominator is the product of fiber width(diameter)and vessel diameter of D.margaritae,so the curve can be drew according to synthetic discriminant factor Ra.The trough of the curve corresponds to the early wood and the peak of the curve corresponds to the late wood,so the curve has a sudden decline in the trend line for the year boundaries.
