研究施肥对降香黄檀(Dalbergia odorifera T.Chen.)营养生长和生殖生长的影响,为不同经营目标的降香黄檀人工林培育提供技术支撑。本研究以8年生降香黄檀为对象,设置N(185.6 g N/株)、P(120 g P_2O_5/株)、K(120 g K_2O/株)、PK(120 g P...研究施肥对降香黄檀(Dalbergia odorifera T.Chen.)营养生长和生殖生长的影响,为不同经营目标的降香黄檀人工林培育提供技术支撑。本研究以8年生降香黄檀为对象,设置N(185.6 g N/株)、P(120 g P_2O_5/株)、K(120 g K_2O/株)、PK(120 g P_2O_5+120 g K_2O/株)、NPK(185.6 g N+120 g P_2O_5+120 g K_2O/株)以及不施肥(对照)等六个处理,调查施肥后盛花期内一年生新梢、叶、花的生长情况。结果表明:6个施肥处理间降香黄檀营养生长和生殖生长均差异显著(P<0.05)。N处理的营养枝率、营养枝复叶数和小叶宽分别比对照提高40.25%、21.75%和9.52%,花序直径和花序生物量则降低12.75%和48.63%,显示N肥能促进降香黄檀营养生长,抑制生殖生长,有利于大径材培育;P、PK处理的营养枝率较对照显著降低47.96%和46.84%,表明P肥和K肥能促进生殖生长,有利于良种选育;NPK处理能同时显著促进营养生长和生殖生长,其营养枝率、营养枝长度、营养枝复叶数、营养枝小叶长、宽和枝生物量比对照提高26.04%、68.16%、32.98%、15.20%、11.40%和83.60%,花序数量和花序生物量亦提高54.20%和49.84%。因此,在降香黄檀人工林培育实践中,可通过调整肥料的NPK配比(偏向N或PK)以实现营养生长或生殖生长调控之目的。展开更多
利用扫描电镜对降香黄檀Dalbergia odorifera T. Chen木材的组织构造进行了系统分析，重点分析了不同类型细胞的纹孔的典型特征。降香黄檀木材导管壁上的纹孔为互列式，附物非常丰富；轴向薄壁细胞壁上为单纹孔，个体较大而数量较小，...利用扫描电镜对降香黄檀Dalbergia odorifera T. Chen木材的组织构造进行了系统分析，重点分析了不同类型细胞的纹孔的典型特征。降香黄檀木材导管壁上的纹孔为互列式，附物非常丰富；轴向薄壁细胞壁上为单纹孔，个体较大而数量较小，成组聚集分布，3～5个一组呈猫爪或花瓣状。木材纵切面上，轴向薄壁组织中常见似“分室含晶细胞”，但经X-射线能谱仪分析表明，这种“分室含晶细胞”中的块状物并不是传统认为的草酸钙等无机盐物质，其主要组成元素为碳和氧，由此可初步认定这种似“分室含晶细胞”中的块状物为树胶类物质。展开更多
