摘　　要：以琼楠木材为研究对象,通过纤维形态分析仪和显微镜对琼楠木材纤维形态进行测定及分析,研究其径向变异规律。结果表明,琼楠木材的纤维长度、宽度、内径、双壁厚平均值分别为1034.75、19.95、11.02、9.03μm,长宽比、壁腔比平均值分别为51.87、0.82,各指标在生长轮径向方向的变化规律具有一定的相似性,均表现为沿髓心向外的生长轮年龄增加而逐渐增大,变化十分显著;琼楠木材纤维的内径受径向上生长轮年龄的影响不显著。以期为琼楠木材的应用以及种植培育提供理论依据。Taking Beilschmiedia fordii plantation wood as the research object,the fiber morphology of Beilschmiedia fordii wood was measured and analyzed by fiber morphology analyzer and micro-interaction system,and its radial variation law was studied.The results showed that the average fiber length,width,inner diameter,double wall thickness,aspect ratio,cavity ratio of Beilschmiedia fordii wood were 1034.75μm,19.95μm,11.02μm,9.03μm,51.87 and 0.82,respectively,each indicator had a certain similarity in the radial direction of the growth ring,the outer growth ring age increased gradually,and the change was very significant;the inner diameter of Beilschmiedia fordii wood fiber was not significantly affected by the radial growth ring age.The results provided theoretical basis for the application and cultivation of Beilschmiedia fordii plantation wood.
