橡胶树(Hevea brasiliensis)是一种高大的热带乔木,在我国通常高达10～20米,20龄以上胸径一般为25～40厘米,40龄以上胸径可达8D厘米。解放以来,我国植胶面积已发展到500余万亩。由于优良高产品系和新技术措施的应用,风寒害严重和低产的胶园需要不断进行更新,因而每年都可提供一定数景的橡胶木材。我国森林资源不足,木材奇缺,研究解决橡胶木材的利用问题,对节约森林资源和提高人民生活具有一定现实意义。为此,我们进行了橡胶木材的材性试验,现将试验结果提供有关方面参考。
Hevea brasiliensis is a kind of tall tropical tree, usually up to 10-20 meters in our country. The diameter above 20 years old is usually 25-40 centimeter, and the diameter above 40 is 8D centimeters. Since the liberation, China’s rubber planting area has grown to more than 500 acres. Owing to the application of fine high-quality products and new technical measures, the rubber plantation with severe and low-grade wind damage needs to be continuously updated so that a certain number of rubber wood can be provided each year. Inadequate forest resources and scarce timber in our country have solved the problem of the utilization of rubber wood and have certain practical significance for saving forest resources and improving people’s life. To this end, we conducted a rubber wood material testing, the test results are provided for reference.
