Introduction to Common Pruning of Pruning

What should we pay attention to in the introduction of common pruning? Next, it is explained that pruning is the main method to coordinate the reasonable growth of all parts of flowers and trees, maintain the tree shape, promote flowering and fruiting, control diseases and insect pests, and more importantly, the neat cut is not easy to damage the flowers and trees. Pruning time: It varies with tree species. 1. Deciduous trees: they can be pruned all the year round. For example, in spring and summer, they can be pruned at any time to remove diseased branches, dead branches and weak branches, or to cut short or long branches. The strong or fine pruning of deciduous trees should be carried out during the dormancy period after deciduous leaves. Because the trees have clear vision after deciduous leaves, it is beneficial to the removal and retention of branches and the correct treatment of the cutting angle of branches. Before pruning, it is necessary to distinguish the growth direction of branches and buds and choose the right one. A branch usually has bud eyes on its left and right sides. If you want to make the branch develop to the right, cut the branch short in front of the bud eyes on the right side which reserve the ideal length of the branch. Because the tree's buds have the dominant law of apical growth, the buds grow fastest at the top of the branches. After the new shoots of the right bud eye grow, they reach the goal of developing to the right, and vice versa. 2. Flower-viewing trees: Flower buds of these trees are mostly formed on the annual branches, and pruning should be carried out after the flowers. For example, plum blossom and jasmine Blossom can be pruned once after the blossom fails. Generally, two or three buds are left on the branches, and a few more buds can be left on the branches that need elongation. After pruning, it can promote the growth of new buds and facilitate flowering in the next year. 3. Fruit-viewing trees: The pruning of this type of trees depends only on the trees. For example, pomegranate blossoms and fruits on new branches that grow from the bearing mother branch. A new branch generally blossoms 1-5 flowers, one of which is at the top of the new branch, and the other is at the axillary branch. The flower at the top of the branch is the easiest to bear fruit. Therefore, the new branches of pomegranate should not be removed before flowering and fruit setting. For example, some trees such as Fujian tea, Pyracantha and so on, blossom and bear mostly on short branches. After blooming and bearing, long branches can be cut short, leaving 2 to 3 knots to form bearing mother branches. 4. Pine and cypress trees: It is advisable to carry out in March to May each year because the growth period of the trees in the north and south is quite different, and the specific time is determined according to the specific conditions. Pine and cypress trees are mainly controlled by bud picking. When the new buds are elongated and the needles are not open, a part of the new buds can be cut off according to the situation. The redundant branches affecting tree shape can be cut or shortened before SAP reaches its flowing peak. Some germinative trees, such as June snow and broomberry, can be pruned four or five times a year. Slow-growing conifers can be pruned once a year. Pruning should be based on different needs, generally there are three kinds of pruning: sparse pruning, short pruning and pruning. 1. Sparse pruning is the removal of unwanted branches from the base. By cutting off unnecessary branches, good ventilation and light transmission can be guaranteed, nutrients can be concentrated on the retained branches, so that the plants are vigorous, flowers and fruits are fruitful, and tree shape can also be maintained.

Before thinning, we should observe it very well, especially for beginners, who have requirements for tree shape. We must not cut it easily, and it is difficult to make up for improper thinning. When pruning, it is not suitable to cut down near the trunk. The base of 0.5-1 cm should be kept according to the different branches'thickness. When pruning, the following branches (with reference to Fig. 1) parallel branches should also be pruned besides those with serious pests and diseases. That is to say, a branch growing parallel to the same direction at close distances can be retained and cut off as needed. (2) superimposed branches. That is to say, if two branches grow from the same part of the trunk, one should be cut off. (3) Reverse branches. That is to say, the opposite branch growing on the main branch should be cut off in general. (4) twigs. That is to say, two branches symmetrically growing from left to right on the same height of trunk or main branch should be cut off. When there are more than two pairs of shoots on the same trunk to be pruned, they should be left, right, left and right first, and then cross-pruned in turn, not only one side (5) upright branches should be pruned. That is, upright branches growing on the main branch should be cut off from the base of the branch. (6) Verticillate branches. That is to say, the branches that grow radially in different directions at the same part of the trunk or main branch. Generally, more than three branches are called verticillate branches. According to the need, the verticillate branch usually leaves one branch in length, or only one branch, and the rest of the branches are cut off. (7) Yaqu branch. That is to say, the main branch is divided into two "Ya" branches, which should be cut off. (8) Crossing branches. That is to say, two branches intersect and one should be cut off.
