栓皮栎(Quercus variabilis Bl.)是我国主要造林树种之一,了解它的地理分布可以供营林和造林的技术措施的参考,同时也可以供给植物地理学和地理学上所需要的一些资料。栓皮栎是一种经济树木,它的树皮木栓层特别发达,是制作软木板等工艺品的原料。我国过去所用的软木如瓶塞等物往往是从外国输入的,它是从一种常绿的欧洲栓皮栎(Quercus suber)的树皮上剥取木栓层加工造成的。其实,我国自产的栓皮栎所形成的栓皮的质量,并不亚于欧洲种。目前,我国上海、广州、合肥、汉口、西安等地都先后成立了软木加工厂,由软木可制出各种的物品,如发动机或导热管的包裹物、航海和游泳的浮具 Quercus variabilis Bl. Is one of the main afforestation species in China. It can be used as a reference for technical measures of its geographical distribution for silviculture and afforestation. It can also supply some information needed for plant geography and geography. Cork oak is an economic tree, its bark cork layer is particularly developed, is the production of cork and other crafts raw materials. The cork used in the past in our country, such as corks, is often imported from abroad and is produced by stripping pith from the bark of an evergreen European Quercus suber. In fact, the quality of the cork formed by the self-produced cork oak in China is as good as that of the European species. At present, cork processing plants have been set up successively in Shanghai, Guangzhou, Hefei, Hankou, Xi’an and other places in China. Cork can produce all kinds of articles, such as the wrap of engine or heat pipe, the floating of sailing and swimming
