<正>杉木是针叶树种中萌芽力很强的树种之一。其1年生的初生茎就着生休眠芽(亦称潜伏芽)。本文对杉木休眠芽着生的位置、生长、分枝和死亡的生物学特性作了初步的观察与研究,并讨论了造林时与此有关的栽植深度和萌芽更新时的伐桩高度。

Chinese fir (Cunninghamia lanceolata Hook,) is one of several species with strong sprout capacity in needle-leaved trees. There are dormancy buds (or latent buds), even on its one-year stem. In this paper, the biological characteristics of the position, growth, branching, dormancy and death of the buds, in relation to the planting depth and height of stump for sprout regeneration have been analysised and discussed.
