摘  要:为探讨截干和施肥对檀香紫檀(Pterocarpus santalinus)、大果紫檀(P.macrocarpus)和囊状紫檀(P.marsupium)的促萌条影响,设置4种截干高度(30cm、50cm、70cm和90cm)和3种施肥方式(复合肥、尿素和复合肥+尿素)对其促萌芽条生长表现进行研究.结果表明:4种截干高度的萌芽条数量为7.4个/株-19.0个/株,芽长为26.8cm-48.7cm;3种施肥方式的萌芽条数量为8.6个/株-19.6个/株,对照组15.4个/株,芽长为26.6cm-51.6cm,对照组41.6cm.结果表明截干高度对3种紫檀属树种萌芽条数量具有显著影响,截干高度越高,萌芽条数量越多,但截干高度对其芽长未达到显著性;施肥对萌芽条数量和芽长均无显著影响,但施用肥料一定程度可促进芽长增加.To explore the effects of the sprouts of Pterocarpus santalinus , P.macrocarpus and P.marsupium by cutting height and fertilizing,which growth were studied with the four different cutting height (30cm,50cm,70cm and 90cm) and the three fertilization methods(compound fertilizer,urea fertilizer and compound fertilizer + urea fertilizer).The results showed that the number of buds of the four cut-off heights was respectively between 7.4/plant-19.0/plant,the longest of which were respectively between 26.8 cm-48.7cm.The number of germination strips of the three fertilization methods was between 8.6 /plant -19.6/plant,while the control group was 15.4/plant.The longest bud lengths were respectively between 26.6 cm~51.6cm,while the control group was 41.6cm.The above results showed that the cutting height had a significant effect on the buds of three Pterocarpus species and the higher the cutting height was,the more the number of buds was.However,the cutting height didn t have a significant effect on their bud length and fertilization treatment had no significant effect on their number of germination strips and bud length,but the application of fertilizer could promote the increase of the length of sprouts.
