樟子松种子林(园)修剪,能改善树冠结构,调节母树的营养状况,促进着花结实.1.剪掉过密的一轮枝层:宜在早春(2～3月)或晚秋(10月下旬～11月上中旬)进行.为了修整骨架,确定树形,首先剪掉过密的一轮枝层(见图1)特别是人工移植营造的实生苗种子林,移植时根系有机械损伤,高生长量往往不大,与上一年和下一年的枝层距离较小,所以必须剪掉.这样,可使各轮枝层不致重复,有利于通风透光.其次,要剪掉没有希望挂果的弱枝和枝下高不及1米的枝条(见图1).
Pinus sylvestris seedlings (garden) pruning, can improve the canopy structure, regulate the nutritional status of the mother tree, and promote the flower sturdy .1 cut off a dense layer of branches: should be in early spring (February to March) or late autumn October to mid-November of November.) In order to trimming the skeleton, to determine the tree shape, first cut off a dense layer of branches (see Figure 1), especially artificial seedlings to create transplanting seedlings, transplant root machinery Damage, high growth is often not large, with the previous year and next year, the branch from the smaller, it must be cut off so that each wheel can not be repeated, is conducive to ventilation and light.Secondly, to cut There is no hope of fruit-bearing weak branches and branches less than 1 meter high branches (see Figure 1).
