本文就采自湖南会同的１４个杉木无性系的主要物理力学性质进行了测计，结果表明：杉木无性系木材的气干密度、顺纹抗压强度、抗弯强度和抗弯弹性模量等主要指标均属小至甚小级，不宜用作结构用材；无性系间物理力学性质差异显著，据此可用木材物理力学性质因子选育优良无性系
In this paper, the main physical and mechanical properties of 14 Chinese fir clones collected from Hunan Huitong were measured. The results showed that the dry density, compressive strength, flexural strength and flexural modulus The main indexes are from small to very small, and should not be used as structural timber. There are significant differences in the physical and mechanical properties between clones. Therefore, the physical and mechanical properties of wood can be used to breed fine clones
