一棵立木,树干约占全树的60～75%,树叶、树皮、枝桠、梢头占15～20%,伐根占1～20%,按传统的木材采运方法,只利用其树干部分,而其余采伐剩余物则遗弃在山场。随着木材综合利用的发展,过去被遗弃的剩余物,已日益受到重视并提到合理利用的议事日程。目前,采伐剩余物的利用率仅达到6～7%,而地下根部剩余物的利用则更为罕少。伐根可获得木纤维,可用于制浆和微生物工业以及纤维塑料等。伐根与树冠枝梢剩余物
A standing tree and trunk account for about 60-75% of the whole tree. Leaves, bark, branches and branches account for 15-20% and spruce root 1-2%. According to the traditional method of timber harvesting, only the trunk part, While the remainder of logging is abandoned on the mountain.
