Technical Field

The invention belongs to the technical field of fir processing, and particularly relates to a fir pretreatment method applied to an artificial forest for solid wood doors.

Background

The cedar is a tree species which is the most widely cultivated, fast growing and high in economic value in the Yangtze river basin and the areas south of Qinling mountains in China. The cultivation area comprises a south slope of Qinling mountain in the north, a south China Tubaishan, an Dabie mountain in Anhui, Jiangsu sentence capacity, Yixing, Yidong Yiyi in south to Guangdong, Guangxi Yulin, Longjin, Yunnan Guannan, Ma chestnut slope, screen edge, Kunming, Huizze, Dali, east from south of Jiangsu, Zhejiang, northern of Fujian, west mountain area, west to four Sichuan great river basin (Luding grinds the east area in the west) and an Anning river basin in the west south of West. The upper limit of the vertical distribution often varies with terrain and climatic conditions. The altitude is below 700 m in the eastern Dabie mountain area, below 1000 m in Fujian Dayunshan area, below 1800 m in Sichuan Emei mountain area, and below 2500 m in Yunnan Dali. China fir is widely distributed in south China, is a main commercial tree species in China, and has yellow-white fir wood, light red brown heart wood sometimes, soft texture, delicate fragrance, straight texture, easy processing, strong corrosion resistance and no damage by termites. The material is mainly used for building, bridge, shipbuilding, ore pillar, timber pile, electric pole, furniture and wood fiber industrial raw materials.

It is estimated that the total area covered by the fir is about 770 million hectares, which accounts for 23.9% of the total area of the Chinese forest. Due to the widespread use of fir wood, the wood-processing industry in china has successfully used wood for furniture manufacture and construction. Although the yield of the fir wood is rich, the fir wood has the technical defects of low strength and short service life when being directly applied to furniture manufacture.
