Spruce modeling should start from young trees and be carried out in winter. Because spruce grows slowly in winter, it can prevent twisted branches or excessive loss of rosin during plastic bending. The shape of young trees is processed from coarse to fine year by year. The trunk will inevitably form a basic skeleton, and then shape the main branches and side branches year by year to achieve a vigorous and beautiful posture.

For spruce which has been formed, in order to maintain its inherent modeling posture, buds should be picked and pruned every year to control the growth of branches and leaves, so as to achieve a moderate density of branches and leaves and a vigorous and green state.

Bud picking is usually carried out in April and May, and the best time is when the bud is pulled out by 2 cm to 3 cm. The flower bud is too short, which is not only inconvenient to operate, but also easy to hurt the base of the flower bud; When the bud is too long, it often begins to form lignification, which is not easy to operate. The method of picking buds is generally to hold the pine buds with thumb and forefinger, and twist them hard, and the pine buds will be picked. If the buds are lignified, cut them with small scissors.

If there are several buds on a branch, you should pick the longest bud in the middle first, and then pick the surrounding buds. In short, when picking buds, we should carefully observe the growth of buds and the tree posture of plants, and make decisions according to its modeling requirements and the specific conditions of buds. In principle, there are more long buds and fewer short buds; More hidden places, less empty places; Greater growth potential and weaker strength. At the same time, when picking flower buds, be careful not to damage the loose flower buds at the base and around the flower buds.

Pruning of spruce can be carried out in the dormant period from late October of/kloc-0 to late February of the following year. Spruce is not suitable for strong pruning because it only sends terminal buds, not adventitious buds. Excessive pruning will easily cause turpentine to flow out of the wound, which will affect the growth and development of spruce. The pruning period is from early winter to early spring, before the sap begins to flow. It is best to seal the trimmed wound with wax, sticky wood, adhesive tape, etc. To avoid turpentine from flowing out.
