邓恩桉邓恩桉介绍 邓恩桉 (EuCahetus dunnii Maiden)科属: 桃金娘科 桉树属别名: 形态特征: 形态特征和柳桉、巨桉相似。邓恩桉的树体中等偏大,在开阔的生长条件下,分枝大而浓密。它的成熟植株可高达50米,树干通直,枝下高能达到30-35米。作为人工林栽培时,它的树干通直度比巨桉的还要好,而且分枝更细。它的木材的心材呈淡棕红色,边材的颜色和心材差异不明显。分布与习性:邓恩桉的耐寒能力较强,苗期和幼树有把握忍受的最低温度是零下5度,随着树龄的增长耐寒能力也会更强。幼苗对极端气温在零下5度以上的低温,对它是安全的,而对超出此范围的温度它很敏感;如果低温持续时间短,它能忍耐的温度还可低些;成林可忍耐的极端低温更低、时间也更长。繁殖与栽培:繁殖方式:籽播、扦插、组培。栽培管理与桉树基本相同。邓恩桉的适宜的立地上的生长速度很快,但应注意邓恩桉生长对立地有一定的要求,应选择土层厚、水肥条件较好的立地种植,否则就很难发挥它的速生潜力。应用:邓恩桉主要用途是作纸浆原料。从造纸性能来看,以邓恩桉4年生的纤维长度在0.6mm之间,邓恩桉的纤维在所有桉树类中是较长的,它的纸浆的抗张强度、撒裂度也是最大的;抄成纸面后纸张的运行性、可加工性,适应性均好于其他树种。所以从制浆造纸的角度来看,邓恩桉是桉树中不可多得的优良树种。由于它具有耐寒能力,在较寒的地区,可成为巨桉的替代树种。邓恩桉的木材密度大于巨桉,而且材性总体优于巨桉,所心也可作锯材。图片:
