How to circumferentially cut an apple tree, how to circumferentially cut an apple tree

How apple trees are circumcised and stripped.

When the apple tree is circumcised, it is generally carried out in May and June in the spring, which can promote the differentiation of flower buds, mainly Biqing and then the backbone branches are 15 20 cm away from the middle part or the smooth part of the side branches, and the force should not be too heavy, only need to cut off the phloem on the bark, in order to facilitate the healing of the wound.

Proper circumcision of apple trees during the growth period can effectively promote the differentiation of flower buds and improve the fruit setting rate, but the circumcision should also be carried out at a reasonable time, generally in late May to early June of each year.

If the ring is cut too late, the cut wound will be difficult to heal in the year, the branch is easy to wither and die, and at the same time, it can be too early before the hand cracks, otherwise it is not conducive to the effect of promoting flowering, mainly for the growth of strong branches first ring cut two knives, and then cut off the surrounding bark at a distance of 1 cm, so as to promote the differentiation of flower buds.

In addition, when the apple tree is circumferentially cut, it should be carried out at a distance of 15 cm from the middle part of the branch of the backbone or the smooth part of the side branches, and it is important not to carry out ring stripping on the main trunk to prevent the tree from weakening, which will have a serious impact on the fruit yield and quality of the plant, and may also shorten the life of the apple tree.

At the same time, when circumcising the apple tree, it is not advisable to use too much force, which is also the precautions in the apple tree circumferential cutting method, only need to cut off the phloem part on the bark, do not damage the cambium layer and lignification part inside, so as to facilitate the healing of the wound, and then pay attention to the disinfection treatment, so as not to breed pathogens.

When the apple tree is circumcised, it is carried out in May and June in the summer, so as to promote the differentiation of flower buds, and the main backbone branches are 15 20 cm away from the middle part or the smooth part of the side branches, and the force should not be too heavy, only the phloem on the bark needs to be cut off, so as to facilitate the healing of the wound.

If the ring is cut too late, the cut wound will be difficult to heal in the year, the branch is prone to wither and die, and at the same time, it can not be too early, otherwise it is not conducive to the effect of promoting flowering, mainly for the growth of strong branches first ring cut two knives, and then cut off the surrounding bark at a distance of 1 cm, so as to promote the differentiation of flower buds.

The effect of ring peeling and circumcision on apple flowering is extremely significant, unless it is a dwarf anvil apple erection orchard does not need to use this technology, other types of apple orchards should not be abolished. In production, it was observed that the ring peeling had a significant effect on flowering in March and October, which is obviously unreasonable to explain the file from the perspective of nutrition alone. The impact of circumferential stripping measures on tree vigor is different in different seasons, and it is best to carry out it in June and August.

Because of the drought and low temperature in spring and autumn, the healing of the ring peel wound will be affected, especially in spring, the ring peel is easy to have a serious impact on the tree potential, and even cause dead trees. The optimal temperature for the healing of a ring peel wound is 20 25 , which happens to be also in 6 August. It is recommended to have the least impact on the tree potential, the best effect, and the most easy to operate the wide ring stripping, and the ring should be bandaged in time after the ring stripping.

Summary. Apple tree ring peeling should generally be carried out after the spring shoots stop growing before the autumn shoots occur, due to the tree potential, year, fertilizer and water conditions are different, generally in late May to early June.

When it comes to sugar orange fruit preservation, we have to mention circumcision, the fruit preservation effect of circumcision on sugar orange is very significant, and this is why we take the risk of circumcision.

For circumcision, there are many people who have a lot of questions, today Mr. Wei Kai will explain the circumcision operation to you, I believe that many novices can also master this skill after reading it.

A note on citrus circumcision

Selection of circumcision tools

Common ring cutting tools have 0 3 knife tools, the choice of 0 knife is called ring cutting, and the choice of 1 3 knife is called ring stripping. The selection of small can not achieve the effect of the sun, the selection of large cut is difficult to heal, the specific according to the strength of the tree, the trunk and the thickness of the main branch and the citrus varieties to choose.

Citrus generally uses No. 0 to No. 2 knives, and grapefruit only uses No. 3 knives. For sugar oranges, mandarins, navel oranges and other varieties, the diameter of the main branch is 3 5cm, and the No. 1 knife is selected, and the diameter is more than 5cm.

Selection of the circumcision location

It should be selected on the smooth trunk main branch, and the circumferential cutting of the main trunk is usually only cut once, and the workload is smaller. If the main stem does not have a smooth position, we choose to do it on the main branch, usually with a few cuts, and the workload is relatively large.

The specific operation method of circumcision

Perform on the smooth trunk and main branches, circumferentially cut a full circle, pay attention to mouth-to-mouth and grasp the strength, cut off the phloem and cambium, and take care not to hurt the xylem. (The specific method can be seen in Mr. Wei's operation**).

Circumcision is not in place

Only the phloem is cut off, but the cambium layer is not cut, or the circumcision is not mouth-to-mouth, and it is easy to circumcision in the groove part; Therefore, it is recommended to check after the circumcision, and if you find that the circumcision is not in place, please make up the knife in time. If the circumcision is not in place, the fruit preservation effect is usually poor.

The circumcision is too heavy

The wrong circumcision tool is selected, or the xylem is cut by improper operation, and it is easy to cut the tree in a convex position. If the circumcision is too heavy, the circumcision will not heal normally, resulting in yellowing and decay of the fruit tree. The circumcision can be wrapped with black electrical tape, which is conducive to the healing of the circumcision.

Circumcision weather options

Circumcision on rainy days or rainfall after circumcision will make the circumcision susceptible to disease, and there will be problems such as glue flow, resulting in noisy wounds that are difficult to heal. Therefore, it is better to carry out it in sunny weather and dry trunks, and the circumferential cutting should be as far away from the ground as possible.

If the fruit tree is infected with flow gum disease, it should be coated or sprayed with methyl tobuzine agent, and then the ring incision should be wrapped with black electrical tape.
