In the past this wood had been primarily used as a board for many uses and products since prehistoric times. After World War II, however, the wood has mainly been utilized as a squared timber post (column) including the pith-centered part of the tree stem for house construction up to the present. The forestry of Cryptomeria japonica will need to adjust to the use of wood in the future; the forest management practices should shift from solid wood products mainly for the columns containing large amounts of juvenile wood with unstable and poor in quality wood to the wood supply for the lumbers manufacturing that uses mature wood with stable and high quality wood in the tree to make a variety of boards., スギは成長が速く,その木材は汎用性に富む.ここでは,将来に向けてスギ材をどう使いこなしていけばよいか,スギ材の性質をふまえて考えた. かつて,わが国では,スギ材をおもに板材として利用してきた.しかし,戦後,今日にいたるまで,心持ち柱としての利用が主体になった.そこで,スギ材の材質特性と需要の仕向け先を考えるとき,品質の不安定な未成熟材が大半をしめる心持ち柱材の生産を中心にした林業から,安定した品質の成熟材を有効につかう板材利用をめざした林木育成への転換を図りたい.}, pages = {103--112}, title = {スギ材の使われ方, 雑考 : オビスギをまじえて}, volume = {57}, year = {2011}, yomi = {キタハラ, リュウシ and キタハラ, リュウシ} }
