Persimmon tree pruning technique points

Core Tip: The main tree types used are generally trunk sparse. Its characteristics are in accordance with natural characteristics, there is a clear central trunk, and the main branches are distributed in distinct layers. Its structure is dry height of about 1 meter, the main branch in the center dry layered distribution, a total of 3 to 4 layers. The first layer has 3 to 4 main branches, the second layer has 2 to 3 main branches, and the third layer has 1 to 2 main branches.

The first layer has 3 to 4 main branches, the second layer has 2 to 3 main branches, and the third layer has 1 to 2 main branches. The height of the tree is about 4 meters, the distance between the main branch is about 30 centimeters, and the interval between the layers is about 60 centimeters. The main branch has redistribution of lateral branches, and the branches on the side branches have branch groups. The crown is conical, and the later canopy is also high. Consider falling in stages.

Trim a young tree trim. The young persimmon tree grows vigorously, and the top bud has strong growth ability and obvious levels. The branching angle is generally small. The main task is to build a skeleton, cultivate a tree, pay attention to the balance between branches and affiliations and the affiliation between the main branches, and timely pick up the heart and promote the mother branch. The dry height is 1.2 meters and the main branch is selected according to the tree structure. To reduce sparse cuts, increase the number of branches. Wangzhi grows to 20~30 centimeters long to pick up the heart, promote the secondary branch, increase the grade of the branch, try to lightly cut, pay attention to the cultivation of the branch group, and prepare for the early results. 2 Pruning of persimmon trees in full fruit period. The persimmon tree is about 10 years old and enters the fruit period. During this period, the tree vigor is stable, the yield is increased, and the outward expansion of the tree body is becoming slower. With the increase of age, new buds of innate buds begin to germinate and appear natural renewal. This task is to pay attention to ventilation and light transmission, to cultivate twigs of internal ridges, to prevent the outward movement of the resulting parts, to achieve a combination of deflation, cultivation of new branches, and extension. The age of the fruit period. Pruning methods are as follows: First, adjust the angle of the backbone branches and balance the tree potential. With the gradual increase of shoots, the light in the interior has deteriorated year by year, coupled with the growth forces relocating, the branches drooping, and the growth and weakness of the internal sprigs. The results are sparse and the phenomenon of self-blight is serious. Should adjust the angle of the backbone branches, and balance the growth forces inside and outside. Too many big branches should be removed in different years to promote the robust growth of the branchlets in the inner branches. The original branch of the old branch was retracted year by year, while supporting the regenerating branch of the rear part of the plant to grow obliquely upwards and gradually replaced the original head in order to raise the main branch angle and restore the growth potential of the main branch. The second is the combination of evacuation and the cultivation of lychees. In the full fruit period, the back of the persimmon tree gradually becomes bald, and the resulting parts move outwards. The pruning should be retracted to promote the regenerating branches of the rear branches. However, most of these regenerating branches are more dense, and they should be weak and strong, and they should be trimmed at the appropriate time. Its branches, culture branches. The persimmon tree has a large number of fruits on the strong branch, and the fruit of the knot is also large, and it is necessary to preliminarily cultivate the strong mother branch. Therefore, the internal litchi group should be shrinking, pay attention to training, the excessively long old branches should be promptly retracted, prompting the occurrence of renewed branches, the short and fine branches should be put back shrink, increase Branch quantity, promote its rejuvenation. The third is the use of leggy branches to cultivate new branches. If there are too many branches in the internal organs, a part of them should be removed. The remaining ones should be picked up in time to promote branching and cultivate sticks. The fourth is to take multiple preparations to overcome the size of the year. As a result, the growth of branches is generally debilitated, and most of the results do not form a continuous result in the year of the result. According to many years of work experience, each year, the results of the branches or 1/3 of the mother of the results should be used as a short cut as a preparation of branches, making it a year apart.

Timely updating is the key to maintaining the tree's vigor. The persimmon tree has a shorter lifespan than the average fruit tree and the sprigs have a shorter life span. After 2 to 5 years, the persimmon tree is weak or dead and should be updated in time. Because of its long life and strong germination power, it can be renewed many times. The timely updating of the persimmon tree can keep the tree vigour enduring, and can extend the age of the fruit period.
