What is the role of persimmon tree ring cutting

Circumferential cutting (stripping) is an important measure to improve the fruit setting rate of persimmon trees, persimmon tree circumferential cutting (stripping) is one of the commonly used fruit preservation measures in production, and the following technical points of circumferential cutting (stripping) are introduced as follows: 1 time: The most suitable period for large-scale persimmon orchard circumferential cutting (stripping) is the first fruit drop to 120-130% of the required fruit setting amount after flowering, it is advisable to choose a sunny day to carry out, and the wound is susceptible to disease before the rain, after the rain and even on cloudy days.

A small amount of persimmon tree circumcision (peeling) can be carried out during the flowering period after thinning the flowers. 2 parts and methods: the circumcision (stripping) part is mainly the main branch or the primary branch on the main branch.

In general, do not peel the trunk, if you need to ring the trunk, you should leave auxiliary branches. Practical experience has proved that setting aside auxiliary branches is the main measure of safe ring stripping. Young trees and early fruit trees can be circumcised in the main trunk, the first circumcision is 20 cm above the ground, after an interval of 7-10 days, it is circumcised again at 5 cm, if the tree is too vigorous, the first circumcision can be circumcised at a distance of 5 cm between two lines; If the tree is still strong, you can circumferentially cut it a third time.

If there is heavy rain after 7-10 days of circumcision, you can circumscribe half a circle at 5 cm above the last circumcision; After heavy rain again, cut half a circle into a full circle. In general, the effect of triple circumcision can be equated to annular stripping. Mature trees can be ring-stripped.

Ring cutting or ring stripping should use a sharp blade, and the operation should be carried out in a flat place of the branch, and the force should be uniform, and the upper and lower knife edges should be parallel when ring stripping. The circumcision depth should be just cut off the phloem without injuring the xylem. The width of the ring stripping, in principle, is one-eighth to one-tenth of the diameter of the ring stripping, the small branch should be 3 5 mm, the large branch 5 7 mm, the diameter of 8---10 cm or more of the adult tree should not exceed 10 mm.

The width of the ring stripping can be determined according to one's own experience and habits, and practice has shown that the width is not the main index factor, the main factor is to look at the length of the healing period. After the ring peeling, the wound should be shaded with a newspaper strip in time. 3. Reasonable control:

In persimmon trees with more vegetative branches than flower branches before flowering, the top flower buds and tender shoots are removed after leaving 3 or 4 flower buds on the flower branches; For trees that are overgrown, the vegetative branches at the top of the crown can be appropriately thinned, and 4 6 leaves can be left for topping; Trees with too many flowers and few vegetative branches should be thinned to a reasonable number.

Hello! Persimmon tree ring cutting plays a role in promoting flower bud differentiation and improving fruit quality. Circumcision is the practice of wrapping around the branches of a plant and peeling off a certain width of bark.

It is a planting measure to promote flower bud differentiation and improve fruit quality, circumcision of the bark (phloem) because the water and minerals absorbed by the root system are transported normally along the duct, and after a period of time, the upper branches of the trephant are grown normally.

Both situations will cause fruit loss, and the specific reasons must be analyzed according to the actual situation. Circumcision of the bark destroys the phloem, reduces the downward transport of organic matter, and can improve the fruit setting rate of fruit trees
