研究表明:松材线虫引起的马尾松(Pinus m assoniana)病树死亡后期,必然有蓝变(Blue-stain)现象。松材蓝变程度与松树树干部位相关性不大。但是,对于同一棵树,若蓝变程度高,则每一部位的蓝变程度都比较高;若蓝变程度低,则每部位的蓝变程...研究表明:松材线虫引起的马尾松(Pinus m assoniana)病树死亡后期,必然有蓝变(Blue-stain)现象。松材蓝变程度与松树树干部位相关性不大。但是,对于同一棵树,若蓝变程度高,则每一部位的蓝变程度都比较高;若蓝变程度低,则每部位的蓝变程度可能都比较低。蓝变程度与松材线虫(Bursaphelenchus xylophilus)的含量也没有正相关关系。在松材线虫病木的检疫过程中,松木蓝变仅可以作为松材线虫病的参考指标。展开更多

In the experiment, 8 kinds ingredient were analyzed by inspections and chromatic aberration. The results showed that: Chinese White Poplar blue-staining were soaked into ingredients 5: 5% NaClO+assistant medicament. The blue-staining of wood could be removed and wood colour and lustre was naturalness.展开更多
