【摘要】 以凉水、草河口、帽儿山三个参试点采集的9年生(帽儿山为15年生)人工林长白落叶松不同地理种源的试验木材,参照国家标准木材物理力学试验方法进行了气干密度、年轮宽和晚材率、管胞长度知长宽比等参数的测试,并通过方差分析、多重比较和综合评估分析等方法处理试验数据。研究结果,选出白刀山种源为优良的制浆材种源,其次为穆棱及和龙种源。从木材性质和制浆木材综合性能的角度评价地理种源的优劣,旨在为种源的选育和造林地的合理配置提供科学依据。更多还原

【Abstract】 According to the National Standard of the test method of wood physical and mechanical properties. The parameters of properties of pulpwood such as density, latewood percentage, width of annual ring, the length of trachied and length-width radio of trachied have been measured from the different geographic provenances samples of nine years old plantation of Larix olgenis, which were collected from Liangshui, Chaohekou and Maoershan. Meanwhile, the deviation analyses, the multiple comparative and the corhprehensive evaluated analyses have been used.The primary results showed that Baidaoshan Mt. provenance is the optimal pulpwood provenance, secondary are Muling and Helong provenances. These information are very important for selection of provenance, and afforestation reasonable disposition of forestland.更多还原
