In different harvesting seasons, the lignin, holocellulose and pentosan contents in bamboos didn''t change too much.
至于同为化学主要组成分的质、全纤维、聚戊醣等成分,则没有季节变化。

To avoid taking those extra steps, expert composters might add extra wood chips or paper products to the pile, since they have a lot of lignin — a tough component of plant cell walls which doesn't contain any nitrogen at all.
为了避免这些额外的步骤,专业的堆肥者可能会往堆肥中再加入一些屑或者纸质品,因为它们含有大量质素,一种完全不含氮的坚韧的植物细胞壁成。
Insects like termites can go whole hog on the whole log, because they can " chew" the wood with their serrated mandibles AND also have the right gut machinery - AKA microbes - to break the lignin down on the molecular level.
像白蚁这样的昆虫可以吃掉整根原,因为它们可以用锯齿状的下颚“咀嚼” ,并且还有合适的肠道机制——也就是微生物——在子水平上解质素。
