| 摘 要： | 测试了红壳竹人工林竹材的物理力学性质。结果表明：竹龄对红壳竹竹材的物理力学性质有显著的影响；竹材的径向、弦向、体积全干缩率随竹龄增加逐渐减少；基本密度、顺纹抗压强度、顺纹抗拉强度和抗弯强度都随竹龄增加而提高，至5－6年生强度稳定在较高的水平上，竹午由下至上，含水率、体积全干缩率逐渐减少；维管束密度、基本密度及力学强度相应提高。

| Abstract: | The physico-mechanical properties of Phyllostachys iridenscens wood from pl antation are determined. The results show that age has a remarkable effect on th e physico-mechanical properties. The full shrinkage ratio of the culm decreases gradually with the age; The basic density, compression strength parallel to the grain,and tensile strength parallel to the grain and bending strength increase with the age,and reach their maximum values at the age of 5-6 years with relati ve stableness. From bottom to top the moisture content and full shrinkage ratio gradually reduce and the bundle density, basic density and mechanical strength c orrespondingly increase. |
