摘要
樟子松是我国三北地区主要造林树种,具有速生、树干通直、蓄积量大等特点。但其采伐后,木材经过一段时间的储存,芯部会出现"蓝变"。这种变化是评价木材质量的一个重要指标,影响木材加工后产品的质量。文章研究确定了樟子松木材变色属于微生物变色类型,分析了樟子松在自然条件的变色规律,为找到控制这种变色的办法提供了理论依据。
Pinus sylvestnis var. mongolica is main afforestation tree species of Three-North Area in China. It has the characteristics of a fast-growing, straight trunk, large volume, etc. But after the logging, timber after a period of storage, the core district in “change blue”. This change is an important index to evaluate the quality of the wood, affect the quality of the product after wood processing. Paper research identified Pinus sylvestris var. mongolica wood color belongs to the microbial change color type, analyzed Pinus sylvestis var. mongolica in color change law of natural conditions, to find a way to control the color change to provide a theoretical basis.
