本文对湖南会同县的杉木木材进行了宏观、微观以及扫描电镜下观察试验。根据4株不同年龄杉木观察,杉木木材构造的变异受生长轮年龄的影响显著;伪轮的出现与生长季中的湿度、温度变化有关. 本试验试图为林业生产单位了解杉木生长规律,确定营林措施提供依据,为杉木木材利用及材质研究提供参考。
In this paper, we conducted the macroscopical, microscopic and scanning electron microscopic observations of Chinese fir wood in Huitong County, Hunan Province. According to the observation of four Chinese fir ages, the variation of wood structure of Chinese fir was significantly affected by the age of growth wheel, and the occurrence of false wheel was related to the changes of humidity and temperature during growing season.This experiment attempted to understand the growth regularity of Chinese fir, Forest measures to provide a basis for the use of Chinese fir timber and materials to provide a reference.
