蚬木是稀有的珍贵树种,木材容重1.167克/cm~3,体积干缩系数0.784%,顺压极限强度1099千克/cm~2,弦面静曲极限强度2111千克/cm~2,弦面顺剪极限强度225千克/cm~2,端面硬度2136千克/cm~2,具有优良的物理力学特性,用途广,为机械、车船、桥梁等良材.为了满足社会主义工农业发展对这珍贵木材的需要,必须大力造林,同时管好现有的天然蚬木林.发展布局宜以大面积石灰岩地层且无寒害的地区作为蚬木林基地,根据蚬木的适应性区划,可将广西石灰岩地层大面积分布的地区分为三个类型区.
Alnus is precious rare species, the volumetric weight of wood is 1.167 g / cm ~ 3, the volume shrinkage coefficient is 0.784%, the ultimate compressive strength is 1099 kg / cm ~ 2, the ultimate bending strength of string surface is 2111 kg / cm ~ 2, Shun shear ultimate strength of 225 kg / cm ~ 2, the end surface hardness of 2136 kg / cm ~ 2, has excellent physical and mechanical properties, wide range of uses, machinery, vehicles, bridges and other good material in order to meet the socialist industrial and agricultural development of this precious wood The need to vigorously afforestation, while managing the existing natural albino grove.Development layout should be a large area of limestone strata without chilling damage as a base of alder wood, according to Alnus adaptability zoning, Guangxi limestone strata large area The distribution area is divided into three types of area.
