Pruning methods of Cherry seedlings

It is very important for cherry trees to grow from seedlings to big trees to bear fruit, and it is very important from the early establishment of the garden to the later management. If one step is not done, it will directly affect the growth of the cherry tree and lead to the yield in the later stage. Among them, the pruning of cherry seedlings is also a very important step.

Pruning methods of Cherry seedlings

The main results are as follows: 1. There are many branches on the young trees, the front leaf buds extend and expand the crown, and the lower axillary buds produce fruiting branches. After entering the fruiting stage, the terminal buds of most annual branches are outside the leaf buds, and most of the axillary buds are flower buds, which are called fruiting branches. According to the length, the fruit branch is divided into long fruit branch 15 cm, middle fruit branch 5 cm, short fruit branch 5 cm, flower cluster fruit branch 1 cm. From the point of view of fruiting ability, the fruiting ability of long fruit branches is poor, generally about 40%. The fruiting ability of medium fruit branches varies from variety to variety. The fruit setting rate of short fruit branches is high and the fruit quality is also good. The flower cluster fruit branch is the main fruit branch on the prosperous tree in the full fruit period, and the fruit setting rate can reach about 80%. The fruit has the best quality and long life, and can bear fruit continuously for 10 to 20 years. Fruiting branches and flower-shaped fruit branches are the basis of yield formation. Chinese cherry and sour cherry have a large proportion of long and medium fruit branches in the early fruit stage, while they are mainly short fruit branches and flower-shaped fruit branches in the full fruit stage.

2. Pruning of young trees in order to promote early fruit of young trees, on the basis of shaping, the pruning of all kinds of branches should be light, mainly in the growing period. In order to control the growth of branches, increase branches, add speed to expand the crown. The time of pruning in winter should be postponed to before budding to avoid dehydration and dryness of the cut. Except for short cutting of main branches and extended branches and appropriate thinning of some overdense and crossed branches, the rest of the middle and branchlets should be retained as far as possible.

Pruning consideration

The main results are as follows: 1. The cut of the pruned branch should be smooth, cut at a 45-degree angle with the cut bud, cut from the opposite side of the bud, the top of the slope is flat with the tip of the cut bud, and the lowest part of the slope is flat with the bud base, so that the cut surface is small, easy to heal, and the bud grows fast after germination. The cut of the sparse branch is cut off at the branch point, leaving no residual pile with the dry flat.

2. When pruning larger branches and trunks, the partial operation method can be adopted. First, at a distance of 20 cm above the required saw, saw all the openings from the lower direction of the branch, with a depth of half the thickness of the branch, cut off the branch from above, leaving a residual pile, and then saw off the residual pile from the saw, which can avoid branch splitting.

3. When sawing off the branches of trees, in order to prevent rain or bacteria from invading and rot, the saw must be flat, disinfect with 20% copper sulfate solution, and finally apply a protective agent to prevent corrosion, dry and promote healing.

Pruning skills of cherry fruit trees

The pruning of fruit trees is often pruned in summer after fruit harvest. Thinning was used to remove the perennial branches which were too dense and disturbed the crown to adjust the crown structure and promote the formation of flower buds. When removing the big branches, pay attention to the wound to be small and flat, so as to heal as soon as possible. When thinning one-year-old branches, you can first cut above the axillary flower buds at the base, and then remove them after the results are bald. When pruning in winter, attention should be paid to the proper retraction of the tip of the backbone branch and the 2-3-year-old branch segment of the short fruit branch, so as to stimulate the vegetative growth and the continuous formation of new fruit branches, and prevent the outward movement of the fruit part and the internal baldness of the crown.

Pruning skills of Cherry Aging trees

The main task of pruning aging trees is to renew and rejuvenate in time and make use of strong growing branches to form new crowns. If the backbone branches are weak at first and do not have the ability to bear fruit, they should withdraw in time. When using hidden buds to retract and renew, the life span of hidden buds of Chinese cherry is about 5-10 years. In order to retract and have branches to renew, it is better to have small branches with more normal growth at the retracted place, which does less damage to the tree. After retraction and pruning, select the direction, position, proper growth and outward development of the branches to cultivate new main branches and lateral branches. Too much should be removed, and the rest should be cut short to promote branching, and then released slowly to form a fruiting branch group. When the twig is renewed, it should also be carried out after fruit picking, so as not to cause glue flow from the wound.

There are many pruning methods for cherry trees, and the pruning methods are different in different periods. Generally speaking, we will use oblique shearing method when trimming, so that the wound is small and the healing will be quicker. In order to prevent infection, we can apply some medicine after pruning. Only by doing a good job can the cherry trees have a higher fruit rate in the later stage.
