不同地理种源的人工林长白落叶松木材材性的研究

参照国家木材物理力学试验方法标准对采自东北林业大学帽儿山实验林场的15年生人工林长白落叶松不同地理种源的试材,测定了气干密度、年轮宽度、晚材率、硬度、管胞长度、管胞长宽比等参数;并通过综合评估分析处理试验数据。鉴于落叶松主要作工程用材和制浆用材,从木材材性角度评价地理种源的优劣,旨在为速生人工林木的定向培育提供科学依据。

A study on the wood properties of the geographic provenances of plantation of Larix olgensis

According to the National Standard of the Test Method of Wood Phsiycal and Mechanical Properties, the parameters of wood properties such as density, latewood percentage, width of annual ring, the length of trachied and length-width ratio of trachied have been measured from the different geographic provenance samples of fifteen years old plantation of larix olgensis, collected from Maoershan Forest Laboratory of Northeast Forestry University. Meanwhile, the comprehensive evaluation analyses have been done. Therefore, the information is very important for selection of provenance and directed education of fast growing plantation.
