摘要:
 以广西大青山林区米老排人工林主伐后的伐桩萌芽条为研究对象,分析不同萌芽条保留数量对米老排伐桩萌芽条生长与生物量积累的影响。结果表明,不同留萌处理措施,随着米老排伐桩萌芽条保留数量的增加,萌芽条的高度与胸径生长呈减小趋势,保留1株萌芽条更具有生长优势;萌芽条器官生物量大小均表现为主干>枝条>叶;萌芽条的总生物量呈现先增加后减小的趋势,保留2株萌芽条的总生物量积累最大,但保留1株萌芽条个体生物量积累明显高于其他处理的单株生物量。建议在米老排伐桩萌芽更新过程中,萌芽条生长1~2 a再进行植株的密度调控处理,如培养薪炭林为主,每个伐桩保留1~2株生长健壮萌芽条;若需培育木材为目的,保留1株生长健壮萌芽条为宜。
Abstract:
 In this paper,effects of reserved sprouting number of Mytilaria laosensis on the seedlings growth and biomass accumulation were investigated with 120 stumps in Daqingshan forest region.Four treatments were applied: 1,2,and 3 sprouts per stump were reserved,no removal of sprouts was served as the control.Along with the increase of the number of reserved sprouts,the mean height and diameter of the sprouts decreased,1 sprout per stump demonstrated higher growth potential.For different parts of a sprout,the biomass ranked as trunk>branch>leaf.With the increase of the number of reserved sprout,the total sprout biomass increased at first and then reduced,in which seedlings of 2 reserved sprouts demonstrated the highest total biomass.However,the accumulation of biomass of 1 sprout reserved was significantly higher than that of other treatment.Reservation of no more than 2 sprouts per stump would achieve the different purposes to the plantation cultivation.
