| 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。 |

| 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. |
| Keywords: | Eucalyptus urophylla Fertilization treatment Wood chemical component |
