摘要：杨树由于具有适应性强、生长快、树干通直、出材率高等优点,已经成为我国三大速生人工林树种之一,但速生杨树木材也存在着密度低、材质松软、变异性大、强度低等缺陷。因此,采用各种技术手段改性处理杨木,对改善杨木性能、拓展杨木应用领域和提高产品附加值,实现杨木资源的高效利用具有非常重要的现实意义。本文较系统地总结、阐述了近年来国内速生杨木增强改性技术方面的研究现状与进展,并对杨木增强改性技术研究中存在的问题和发展思路进行了探讨,以期为杨木增强改性处理技术的后续研究和工业化应用提供参考和借鉴。
Because of its environment adaptability, rapid growth, straight trunk and high percentage yield, poplar is widely cultivated and becomes one of the three species of fast-growing plantation in China, but it also has some troublesome inherent properties like low density, low natural durability, and poor strength properties which limit its end-use. Consequently, it is significant to improve poplar wood’s performance, expand application fields, enhance added value and realize efficient utilization of poplar by modification such as compressive densification, low molecular resin impregnation and so on. This will ultimately have a significant impact on alleviating the shortage of natural forest resources. The current research progress on reinforcing modification of fast-growing plantation poplar were summarized, meanwhile, some existing problems and future research direction were discussed, which might provide references to further study and its industrial application.
