树桩养坯须做到既要“促生”又要注意“克制”,两者相辅相成,这样才能把树坯养好。所谓“促生”,即促使根系的吸收与枝叶的光合作用,制造和积累养分,使桩景生长良好。“克制”主要是减轻树坯体内能量的消耗,使吸收的养分与消耗的养分达到基本平衡。具体地说,即要做到以下四方面:一、“放养”与“固本”树桩成活后,第一年最好任其生长,不加修剪,这就叫“放养”。任树坯自然生长,不可修剪一枝一叶, Tree stumps must be both to “promote” but also pay attention to “restraint”, the two complement each other, so as to nurture the tree bark. The so-called “Promote Growth”, that is to promote the absorption of roots and foliage photosynthesis, manufacture and accumulation of nutrients, so that the growth of good piles. “Restraint” is mainly to reduce energy consumption in the body of the tree billet, so that the absorption of nutrients and nutrients consumed to achieve a basic balance. Specifically, we must do the following four aspects: First, “stocking” and “solid” After the survival of the stump, the first year is best to let it grow, without pruning, this is called “stocking.” Ren bark natural growth, can not trim a leaf,
