红松(Pinus koraiensis Sieb.et Zucc.)的材质优良,工艺价值高,是我国一种最主要的用材树种,也是我国小兴安岭及长白山林区的主要森林树种。我国除存在大量的红松天然林外,还有一些红松人工林,近年来并大力提倡营造人工林。草河口林场的红松人工林培植于30年前,其林木特性及木材强度和容重在1959年甚至在此以前已有过研究,但对于基本材性(构造和物理、力学性质)方面的综合研究则尚未进行。基本材性是衡量材质的主要根据,而材质的优劣又是营林、木材生产和利用部门最关心的问题。为此作者等乃拟就本题,在立地条件类似的人工林和天然林内
Pinus koraiensis Sieb.et Zucc. Is one of the most important species of timber species in China. It is also the main forest tree species in China’s Xiaoxing’an Mountain and Changbai Mountain. In addition to the existence of a large number of natural Korean pine forests, there are some Korean pine plantations, and in recent years and vigorously promote the creation of plantations. The Pinus koraiensis plantations in Caohe Estuarine Farm were cultivated 30 years ago and their tree characteristics and wood strength and bulk density were studied even before 1959. However, for the synthesis of basic materials (structure and physical and mechanical properties) Research has not been done yet. Basic material is the main basis for measuring the material, and the merits of the material is the forest, timber production and use of the most concerned issues. For this reason, the author is going to propose this question in planted forests and natural forests with similar site conditions
