How do you prune large cherries? When is the fall pruning time for big cherries?

When pruning large cherries, it is suitable to carry out light and short truncation method in the juvenile growth stage, mainly cutting off a quarter of the excessively long branches to weaken the advantage of the top, and re-pruning the thick branches in the peak growth season, and the length of the pruning is one-third or two-thirds, so as to inhibit the growth of the strong branches and promote the development of fruiting branches.

How to prune large cherries.

1. Light stub truncation method.

Because the growth period of large cherries is relatively short, proper pruning can promote the growth of plants, and the light stubbing method is the basic requirement of how to prune large cherries, mainly the cherries are thinned and the excessively long branches are cut off about a quarter, so as to weaken the advantage of the top, and the horizontal branches or oblique branches are generally lightly stubbed on the young trees to facilitate the fruit.

2. Medium and short truncation method.

The medium and short truncation method is mainly carried out in the peak season of large cherries, mainly cutting the thick branches by one-third or one-half, and in the whole pruning process, the backbone branches and the branches with growth space on the periphery are shortened, so as to promote the growth of branches and expand the canopy.

3. Heavy stub method.

Generally, when the young tree grows faster, the perennial branches of the large cherry are cut short by two-thirds, so that the growth potential of the strong branches can be reduced, and it is also conducive to cultivating the fruiting branches.

4. Extremely heavy stub method.

This pruning method is mainly aimed at controlling the competitive branches and over-vigorous branches, generally when the growth rate of large cherries is very fast, the backbone part is properly thinned, and the branches with 4 or 5 axillary buds at the base are shortened, only need to keep about 1 2, and then thinn after the fruit.

There are these pruning methods for large cherry trees, and good pruning methods are for the tree to be vigorous and the cherries are large.

The autumn time of the big cherry should be after September, the new shoots are no longer extended, the growth is basically in a semi-stopped state, the tree is not sensitive to the response of pruning, and the tender green part of the top of the new shoots is still growing, constantly consuming the nutrients produced by the old leaves, so we can cut off the tender green shoots of the current year's branches, which can save nutrients and promote the development of the branches themselves and flower buds and leaf buds.

Retract the long branches 1 3, properly thin the over-dense branches that are shaded on the periphery, open the light path, promote the development and enrichment of the inner branches, and apply a protective agent to the large shear to promote healing. Planned dense plantations can be reduced.

Trimming considerations.

1) The cutting edge of the pruning branch should be smooth, and the cutting bud is inclined at an angle of 45 degrees, cut down from the opposite side of the bud, the upper part of the inclined plane is level with the tip of the cutting bud, and the lowest part of the bevel is flat with the bud base, so that the cutting wound surface is small, easy to heal, and the bud grows fast after germination. The cutting edge of the thinning branch is cut off at the branch point, and the dry level does not leave a residual pile.

2) When pruning larger branches and trunks, the split operation method can be used. First 20 cm from the top of the required saw edge, from the bottom of the branch to the top of the saw, the depth is half of the thickness of the branch, from the top of the branch sawing off, leaving a stump, and then sawing off the stump from the saw edge, can avoid branch splitting.

3) In order to prevent rain or germs from invading and rotting when sawing off tree branches, the saw mouth must be flat, disinfected with 20% copper sulfate solution, and finally coated with protective agents (protective wax, blending paint, etc.) to prevent corrosion and dryness and promote healing.

Large cherry autumn shears generally refer to the pruning in August and October, and autumn pruning is a necessary supplement to summer and winter shears. Because the growth is basically in a semi-stopped state after entering autumn, the tree body is not sensitive to pruning, and cutting off the tender green shoots of the current year's branches can save nutrients and promote the development of the branches themselves, flower buds and leaf buds.

How cherry trees should be pruned, the rural guy will teach you, and you will understand after reading the on-site explanation.

When pruning large cherries, it is suitable for light and short truncation in the juvenile growth stage, mainly cutting off a quarter of the excessively long branches to weaken the advantage of the top, and re-pruning the thick branches in the peak growth season, and the length of the pruning is one-third or two-thirds, so as to inhibit the growth of the vigorous branches and promote the development of fruiting branches.

How to prune large cherries. 1. Light stub truncation method.

Because the growth period of large cherries is relatively short, proper pruning can promote the growth of plants, and the light stubbing method is the basic requirement of how to prune large cherries, mainly the cherries into the eggplant core row thinning treatment, the excessively long branches are cut off about a quarter, in order to weaken the advantage of the top, generally on the young tree to the horizontal branches or oblique branches for light stubbing, in order to facilitate the fruit.

2. Medium and short truncation method.

The medium and short truncation method is mainly carried out in the peak season of large cherries, mainly cutting the thick branches by one-third or one-half, and in the whole pruning process, the backbone branches and the branches with growth space on the periphery are shortened, so as to promote the growth of branches and facilitate the expansion of the canopy.

3. Heavy stub method.

Generally, when the young tree grows faster, the perennial branches of the big cherry are cut short by three thirds, so that the growth potential of the strong branches can be reduced, and it is also conducive to cultivating fruiting branches.

4. Extremely heavy stub method.

This pruning method is mainly aimed at controlling the competitive branches and over-vigorous branches, generally when the ridge of the large cherry growth rate is very fast, the backbone part is properly thinned, and the branches with 4 or 5 axillary buds at the base are shortened, only about 1 2 can be retained, and then thinned after fruiting.

The pruning methods of large cherry trees are: light stub method, medium stub truncation method.

1. Light stub truncation method.

Cutting off one-fifth to one-quarter of the cherry branches has the effect of weakening the advantage of the tip of the branches, better improving the germination rate, increasing the number of short branches, and helping to form more bouquet-like fruiting branches in the later stage. It is often used on horizontal and oblique branches on young trees to help them bear fruit early.

2. Medium and short truncation method.

Cutting off one-third to one-half of the cherry branches is often used in the shaping and pruning of cherry trees, and the backbone branches and the developing branches with growth space on the periphery can better promote the development of medium and long branches, which is conducive to expanding the canopy.

Trimming considerations.

1. Pruning time.

The best pruning time for large cherry trees is in June and July in summer every year, and in November and December in the winter digging season, and when pruning large cherry trees, it is necessary to determine the specific time according to the local weather chaos and ecological environment, and it is best not to prune the plants in the rainy season, so as not to rot the big cherry trees.

2. Scattered search and maintenance management.

When maintaining large cherry trees, it is necessary to apply nitrogen, phosphorus and potassium compound fertilizer to them in the peak growth season to promote the differentiation of flower buds of large cherry trees and make them bear fruit quickly, and during the pregnancy bud of large cherry trees, it is necessary to cut off the flower branches that grow too much to avoid nutrient dispersion and make the fruit quality of large cherry trees better.

Pruning method of large cherry trees: truncation treatment, the vigorous branches are appropriately cut short, and the main branches are left 3 5; Thinning pruning treatment, cutting off useless branches such as long branches, cross branches, overlapping branches; Prune after fruiting, cut off part of the weak branches, and cut off the residual flowers and dead branches; Winter pruning, after the pruned shoots have been sterilized, they can be used for propagation by cuttings.

After the big cherry tree loses its fruit, because of the fast growth rate, the dense branches inside can be thinned and pruned, only need to leave 3 or 5 key branches, and the rest are all cut off, and then the flower buds are cut off to promote flowering again.

Under the premise that the big cherry tree grows well, it can also be pruned at the bottom of the branch, under the premise of germinating long branches, it should be cut first, in addition to the cross branches, overlapping branches are cut off, some branches are very thin due to lack of light, and they also need to be cut off.

Thinning dense branches and solving the dorsal branches, early fruit large cherry tree branches, easy to lead to more crown branches, too much bulk density, greatly affect air circulation and light transmittance, should be in accordance with the basic principle of removing the weak and leaving the strong, the key is to cut off the dense branches.

Large cherry trees grow slowly in winter, so they can be pruned well, and the rotten and dead roots can be cut off, soaked in disinfectant solution for a few minutes, and then placed in a ventilated place to dry, and then put them back in pots and replanted.

When pruning large cherry trees in summer, it is necessary to prune them in the summer and winter periods of each year, and when pruning large cherry trees in summer, it is necessary to cut off their diseased branches, unfruitful branches and diseased branches to promote their germination of side branches, and when pruning large cherry trees in winter, they should cut out the branches and leaves that grow too densely, so that the plants can survive the winter smoothly.

1. Pruning time.

The best time to prune large cherry trees is in June and July in summer and November to December in winter, and when pruning large cherry trees, you need to decide the specific time according to the local weather conditions and ecological environment, it is best not to prune the plants in the rainy season, so as not to rot the big cherry trees.

2. Summer pruning

When breeding large cherry trees in summer, it is necessary to cut off all the weak and diseased branches and unfruiting branches of the plant to avoid the loss of excess nutrients, promote the germination of strong new branches of the large cherry tree, and cut off the diseased and insect branches of the large cherry tree in time, and then spray the fungicide to it, so that the plant grows healthily.

3. Winter pruning

When cultivating large cherry trees in winter, it is necessary to cut the branches and leaves that are too dense to improve the light transmission and ventilation in the canopy, and promote the vigorous growth of the large cherry trees, and use quicklime, sulfur powder and water to make a whitening agent, and then brush it on the trunk of the large cherry tree.

4. Maintenance management

When maintaining large cherry trees, it is necessary to apply nitrogen, phosphorus and potassium compound fertilizer to them in the peak growth season to promote the differentiation of flower buds of large cherry trees and make them bear fruit quickly, and during the pregnancy bud of large cherry trees, it is necessary to cut off the flower branches that grow too much to avoid nutrient dispersion and make the fruit quality of large cherry trees better.

Pruning techniques for large cherry saplings:

1. Pull branches. The purpose of pulling branches is to open the angle, ease the branch potential, transfer the nutrient flow direction of the branch group, weaken the apical dominance, inhibit and promote local development, and achieve the purpose of early flowering, early fruiting and early yield. In fact, it can be done in summer and autumn, the only thing is that it cannot be pulled in winter.

2. Carved buds. Large cherries are not easy to form branches, and when the buds are enlarged, carving buds above the buds is an important means to promote the growth of new shoots. The depth of the carved buds is about 2mm, so as not to hurt the xylem.

Cultivate the main branch, and the length of the carved bud is greater than half of the circumference of the branch; In the middle branch or fruiting branch group, the length of the carved bud is one-half of the circumference of the branch; Cultivate short branches or leaf clusters, and cut the bud length to one-third of the circumference of the branch.

3. Stubbing. In order to strengthen the growth potential of the branches, the stub is divided into light stub, medium stub, heavy stub and very heavy stub. Light stubbing is to cut off the 1 4 1 3 of the front end of the annual branch to reduce the growth potential of the branch and increase the number of medium and short branches.

The stub is to cut off the 1 2 of the front end of the annual branch, and the growth of the branch is strong, which is conducive to the expansion of the canopy; Heavy stubbing is to cut off the 2 3 of the front end of the annual branch of the acacia to promote the growth of vigorous branches, increase vegetative branches and long fruit branches; The extremely heavy first chain stub is to cut the annual branches within 5 cm, only retain the base of the deflated buds, weaken the growth of new branches, and promote the flowering of strong branches.

4. Shrink lead celery and cut it. Also known as retraction, it refers to the stubbing on perennial branches, and its function is to reduce the baldness of fruiting branches, and the renewal and rejuvenation of old trees, weak trees, and main branches.

5. Sparse shearing. Removing the branches that are too vigorous, too dense, and disturbing the shape of the tree from the base is called thinning pruning. Thinning is conducive to ventilation and light transmission, and prevents baldness in the inner chamber. Cherry wounds are not easy to heal, and thick branches should be thinned in stages.
