【摘要】 以16年生的湿地松林分为试验对象，设置3种处理方法进行对照分析，探讨不同处理下保湿保水沟对采脂湿地松木材纸浆特性及松脂成分的影响。结果表明：除木材基本密度外，管胞长度、管胞宽度、管胞长宽比、综纤维素、纤维素、木质素及松脂成分含量在不同处理之间均没有显著差异；随着保湿保水沟深度的增加，采脂湿地松植株的木材基本密度、管胞长度、管胞长宽比、综纤维素、纤维素含量逐渐增加，但木质素含量逐渐减少；保湿保水沟处理的湿地松松脂成分组成与对照完全一致，但湿地松松脂各种成分的含量随着保湿保水沟深度的增加，其变化趋势并不一致。更多还原

【Abstract】 Taking 16-year-old Pinus elliottiias as materials, the effects of intercepting ditch on pulping characteristics and oleoresin monoterpene components of tapped P.elliottii with three different treatments were conducted. The results showed that besides the wood basic density, there were no significant differences in tracheid length, tracheid width, ratio of tracheid length to width, holocellulose content, cellulose content, lignin content and the content of oleoresin monoterpene components among different treatments. With the increase of intercepting ditch depth, wood basic density, tracheid length, tracheid width, ratio of tracheid length to width, holocellulose content and cellulose content increased gradually, while lignin content decreased gradually.The composition of oleoresin monoterpene components was exactly the same as the control, while the change trend was different.更多还原
