我省马尾松林约占全省现有林地面积的60%,并且目前又正在大力发展湿地松、加勒比松等速生热带、亚热带松类,因此,以松木代替杉木,这在木材利用上是一个重要的课题。为了达到以松代杉,当前必须突破两点:(1)胀缩变形;(2)白蚁蛀食。据文献介绍,美国对南方派松材的利用,主要通过以下途径来解决它们的一些缺陷:(1)采用适当的木材干燥方法,例如蒸气干燥等,以解决变形问题,并可加上一些药物处理,来提高对白蚁蛀食的抵抗能力;(2)加工制材时尽量避开一些松材结构上的缺陷,例如应压木的木材偏心现象等。我省肇庆市房管局、广州市住宅建设公司等单位,在这方面已进行了一些试验和探索,希望有关部门要引起对这个课题的注意,并且开展一些试验研究工作。这篇文章所介绍的一些做法是基本上可以的,但对一些问题的认识,如松木变形与树脂含量的关系,尚值得商榷。
Masson pine forest in our province accounts for about 60% of the existing forest area in the province, and is currently developing vigorously tropical and subtropical pine such as Pinus elliottii and Caribbean pine. Therefore, replacing pine by pine is an important factor in wood utilization The subject. In order to achieve Pine cone, the current must break two points: (1) expansion and contraction deformation; (2) termites eating. According to the literature, the United States uses pine wood in the south to solve some of its shortcomings mainly through the following approaches: (1) Appropriate wood drying methods, such as steam drying, are used to solve the problem of deformation and some drugs can be added Processing, to improve the resistance to termite infestation; (2) processing of timber as far as possible to avoid some of the structural defects of pine wood, timber should be pressed wood eccentric phenomenon. Zhaoqing City, Shaanxi Province, the Housing Authority, Guangzhou City, residential construction companies and other units, in this regard have conducted some experiments and exploration, I hope relevant departments should arouse the attention of this issue, and to carry out some experimental research. Some of the approaches described in this article are basically acceptable, but some of the issues, such as pine wood deformation and the relationship between resin content, is still debatable.
