广东高州生长的马尾松由于树皮厚薄,松脂产量高低和枝条伸展情况而被分为三个类型——黑鳞松、黄鳞松和垂枝松。 本文试图通过对其材性的研究比较,从中发现它们之间在木材解剖和物理力学性质上的大小和差异。研究结果表明:黑鳞松材色较深,晚材率较高,管胞较长,轴向树脂道较多;黄鳞松则管胞壁较厚,各项力学性质较高,垂枝松除年轮较宽外,各项性质均低于前者。但根据方差分析检验,三个变型之间的主要性质均无显著差异,而各单株之间则差异显著或极显著。作者等认为在选择马尾松优良类型时,不应该依不同变型划分,而应从单株优树进行选择,这样可能更为有效。
Masson pine growing in Gaozhou, Guangdong Province, is divided into three types due to the thickness of the bark, the level of rosin production, and the extension of shoots - Scots, Scotsmania and Weeping pine. This paper tries to find out the size and difference between them in wood anatomy and physical and mechanical properties through the comparison of their material properties. The results showed that the color of black scale was deeper, the rate of late wood was higher, the tracheid length was longer and there were more axial resin channels. The tube wall was thicker and the mechanical properties were higher. Wide, the nature is lower than the former. However, according to the analysis of variance test, there was no significant difference between the three main types of variation, but the differences among the three varieties were significant or very significant. The authors believe that in selecting the excellent type of masson pine, it should not be divided according to different variants, but should be selected from the single superior tree, which may be more effective.
