木屑占木材加工总量的8—10％。每年扔掉木屑达百万吨。我国年采伐木材的5000余M~3,其中约有40％径制材加工,年生产的木屑相当于200万m~3的木材,而多数的木屑还未被利用。在森林匮乏,出现资源赤字的今天,充分合理利用现有木屑资源,是林业科技人员值得研究的问题,目前国内外利用木 Wood chips account for 8-10% of the total amount processed. Throw away millions of tons of sawdust each year. In our country, more than 5,000 M ~ 3 logs are harvested each year, of which about 40% is made of lumber. The annual output of wood chips is equivalent to 2 million m ~ 3 timber, while the majority of wood chips have not yet been used. In the absence of forests and the emergence of a resource deficit, it is a question worthy of study by forestry scientific and technological personnel to make full and rational use of existing woodchips resources. At present,
