The shaping and pruning of privet

1. Transplant pruning When transplanting in nursery, the trunk should be shortened by 1/3. Only one strong bud can be selected under the shearing to develop into a trunk extension; the other bud opposite to it must be removed. In order to prevent the emergence of apical competition shoots, the first to second pairs of buds under the cut should be destroyed at the same time.

2. Before planting, cut off 1/3 of the annual extension branch of the central trunk of the big seedling, cut off the bud to leave strong buds, and remove one bud from the first pair of buds below the cut to ensure the advantage of bud selection. In order to prevent competition from occurring at the top, the second and third pairs of axillary buds below the cut should be destroyed. The other branches located in the lower part and middle of the central trunk should be selected to stay 3 to 4 (determined by stem height), with certain intervals and staggered distribution of branches. Each main branch should be cut short, leaving buds, stripping buds, to expand the crown, keep the crown ventilation and light. The rest of the thin branches can be slowly put not cut, auxiliary trunk growth.

Summer pruning is mainly to cut short the main branch of the main branch of the competition branch, continue to weaken its growth potential. At the same time, cut off the sprouts on the trunk and roots.

The second year winter shear, still want to cut short the center trunk extension branch, but leave bud direction and the first year opposite. In case of competition branches in the upper part of the central trunk, it is necessary to retract or shorten in time to weaken the growth potential. As long as the first year is properly pruned, in addition to an extended branch at the top, several branches can be born in the lower part. One to two branches with certain intervals and staggered with several main branches selected in the first year should be selected as the second layer of main branches, and moderately truncated. In the third year, winter pruning should be similar to that of previous years, but due to the height of trees, one or two main branches at the lower part of the trunk should be thinned year by year to gradually increase the height under the branches.

3.、For the large seedlings of Ligustrum lucidum which have been neglected for many years and have no obvious extension branches in the central trunk, one branch with a straight growth position and a trunk should be cut short as an extension branch of the trunk. At the same time, one bud and two pairs of buds below the cutting should be stripped or destroyed. The other strong main branches should be thinned out according to their position and strength, or the corresponding cutting measures should be taken to suppress their growth and promote the vigorous growth of the central main branch. Form a strong backbone. At the same time, to select the appropriate position of the branch as the main branch (pay attention to appropriate spacing and staggered distribution) for short, short from bottom to top, one by one shortened, so that the crown under the big and small. After 3 to 5 years of pruning, the trunk height is enough, you can stop pruning, let it grow naturally.
