马尾松是我国南方几省产量最大的树种之一,它在所生产各树种木材中的比重逐年有所增长,估计每年约有千万立方米的马尾松用于工农业生产。马尾松具有生长较快,适应强的特点。材质上的各种物理力学强度并不逊于杉木,但马尾松主要缺点是容易腐朽变质,也容易受虫蛀和白蚁为害。马尾松带皮原木在暖季存放一、二周即有青变菌侵入,边材部份就会青变,时间稍长就随之有木材腐朽菌侵入。马尾松边材较宽,含有丰富的糖分和有机质是木材腐朽菌的营养基,木材腐朽菌能吸取
Pinus massoniana is one of the tree species with the largest output in several provinces in southern China. Its mass proportion of each tree species produced has been increasing year by year. It is estimated that about 10 million cubic meters of masson pine are used for industrial and agricultural production each year. Masson has a fast growing, strong adaptability. The physical and mechanical strength of the material is not inferior to that of Chinese fir, but the main disadvantage of masson pine is that it is easily decayed and degenerated, and is also susceptible to moth-eaten and termites. Pinus massoniana skin logs stored in the warm season for one or two weeks that green algae invade the sapwood will be part of the green change, the longer the time there will be invasive wood decay bacteria. Masson sapwood wide, rich in sugar and organic matter is the decaying bacteria fungi, wood decay bacteria can absorb
