研究了30年左右生红皮云杉人工林木材的主要物理力学性质,并对人工林与天然林木材基本密度的径向变异及主要材性差异进行了比较。结果为:(1)由于红皮云杉35年生人工林尚处于幼龄期,其木材的主要物理力学性能指标均低,其中基本密度0.318g/cm3,顺纹抗压强度29.21MPa,抗弯强度56.63MPa,弯曲弹性模量7.788GPa。(2)人工林木材的密度、干缩率以及顺压强度、抗弯强度均略低于天然林,而吸水率和弯曲弹性模量则稍高,但其差异均不显著。表明通过采取适当的营林措施,红皮云杉人工林达到速生优质是可能的
The main physical and mechanical properties of the wood of Picea koraiensis plantation were studied in the past 30 years. The radial variations and the difference in the basic wood material density of plantation and natural forest were compared. The results are as follows: (1) Because the 35-year-old plantation of Picea koraiensis is still young, the main physical and mechanical properties of the wood are low. The basic density is 0.318g / cm3, the compressive strength of the grain is 29.21MPa, Bending strength of 56.63MPa, flexural modulus of 7.788GPa. (2) The density, dry shrinkage, compressive strength and flexural strength of plantations were slightly lower than natural forests, while the water absorption and flexural modulus were slightly higher, but the differences were not significant. This shows that it is possible to achieve fast-growing and high-quality red-spruce plantations by adopting proper silvicultural measures
