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。
The experiment woods of 9-year-old (15-year-old capitals) artificial forests planted with different geographical provenances from cold water, Caohe estuary and Maoershan mountain were air-dried with reference to the national standard timber physical and mechanical test method Density, annual ring width and latewood rate, tracheid length and aspect ratio, and other parameters of the test, and by variance analysis, multiple comparison and comprehensive evaluation of analysis and other methods to deal with the experimental data. The results showed that the Baijueshan provenance was the fine pulp source, followed by Muling and Helong provenance. The advantages and disadvantages of geographical provenances are evaluated from the perspectives of wood properties and pulverized wood comprehensive performance. The purpose is to provide a scientific basis for the breeding of provenances and the rational allocation of silvicultural land.
