木材短缺,已成为一个严重的国际问题。世界各国,除着力于木材的综合利用,寻求木材代用品的同时,还积极寻找其它原料,发展各种新型的人造板。主要是1年生植物茎杆,如棉杆、玉米秆、麦秆、稻秆等,其次是农副产品的加工剩余物,如蔗渣、花生壳、稻壳等等,用以制造人造板。1973年世界非木质碎料板产量已达170万m~3。 The shortage of timber has become a serious international problem. In addition to focusing on the comprehensive utilization of wood and looking for alternative wood products, the countries in the world are also actively looking for other raw materials and developing various new types of wood-based panels. Mainly 1-year-old plant stems, such as cotton stalks, corn stalks, straw, rice straw, followed by processing residues of agricultural and sideline products, such as bagasse, peanut shells, rice husk and so on, for the manufacture of plywood. The production of non-wood particleboard in the world in 1973 reached 1.7 million m 3.
