摘要:

通过对5种施肥处理下的9年生尾叶桉纸浆材的主要化学成分含量进行测试,以此为基础,进而分析讨论施肥处理对尾叶桉木材化学成分含量的影响规律。结果表明:施肥处理对尾叶桉纤维素含量和木素含量没有显著影响,而对抽提物含量和戊聚糖含量有极显著影响;施肥处理会显著提高木材中冷水抽提物、热水抽提物、1%NaOH抽提物和戊聚糖含量,而且施肥量愈大,木材中戊聚糖含量愈高。

关键词: 尾叶桉, 施肥效应, 木材化学成分

Abstract:

Contents of major chemical components of 9-year-old Eucalyptus urophylla trees with 5 different fertilization treatments were determined.Based on the obtained data, law of effects of fertilization treatments on contents of wood chemical components were analyzed and discussed in detail.Results show that fertilization treatments have no significant effects on the contents of cellulose and lignin, but have extremely significant effects on contents of extractives and pentosan.Fertilization treatments can significantly improve the contents of cold-water extractives, hot-water extractives, 1% NaOH extractives and pentosan.And the larger the amount of the fertilizer applied, the higher the content of pentosan.

Key words: Eucalyptus urophylla, Fertilization treatment, Wood chemical component
