How do you prune an old walnut tree, how do you prune a three year old walnut tree?

Old walnut tree. The trimming method steps of .

Pruning of backbone branches: In order to control the height of the fruiting tree, the top three-pronged branch can be used to gradually fall the head, and the uppermost main branch can be used instead of the tree head, so that the height of the tree can be controlled at about 6 meters. The main branches of the fruiting tree at all levels continue to extend, and the canopy.

It is also expanding. To this end, it is still necessary to pay attention to cultivating a firm and gradually extending skeleton, controlling the back branches in time, and retracting the drooping branches to maintain the growth of the branches. If the branches are drooping, you can use the oblique branches to take the head to make the branches rejuvenate.

Pruning of surrounding branches: For overly dense branches, cross branches, and overlapping branches on the periphery of the canopy, they should be thinned or retracted in time. For some weak branches with insufficient light and greater consumption than accumulation, they should be thinned out in time, so as to meet the requirements of evacuation of peripheral branches and non-empty inner chambers.

Pruning of fruit branch groups: For walnut trees that have entered fruiting, it is necessary to select and cultivate fruiting branch groups in a planned manner.

According to the size of the space occupied and the distance between it and the surrounding backbone branches, the method of retraction or stubbing can be adopted to gradually transform it into a large or medium-sized branch group.

Using strong development branches, for the strong branches that are born in the middle or outside of the main and side branches, the strong branches can be left strong and weak, and the left development branches can be gradually transformed and cultivated into medium or small branch groups.

Control the long branches, and control and use the long branches in the inner chamber if the parts of the body are suitable and do not affect the ventilation and light transmission. In general, it is released in the first year, and in the second year, it retracts at the weaker branches, and is cultivated into a small fruiting branch group. Keep a distance of 60-100 cm between the branches to ventilate and let in light.

For the aging branch group, it should be retracted and rejuvenated in time.

The pruning mantra for walnut trees is "control the strong head and retract the long mother branch; Cut the autumn branches before cutting, and take the flower head after cutting; The branch group should be renewed, and the weak branches should be left behind; Winter scissors do not leave heads, and there is no shortage of heads in the coming year. ”

According to the above pruning methods, it is very beneficial for walnut flowering and fruiting, but it should be noted that the pruning of young trees can be heavier, and for large trees, it is suitable for light pruning is not suitable for heavy pruning, and it is necessary to master the degree.

Maintenance requirements: In fact, the management method of walnut tree is very simple, usually put it in mild sunlight, give it at least 6 hours of light every day, so that the walnut tree can grow better in the soil, put it in a ventilated environment, but also prevent the harm of pests and diseases, which is conducive to the growth of walnut trees.

Water and fertilizer management is a crucial step, can not blindly water and fertilize, whenever the seeds are sown into the potting soil, you need to water in time, keep the potting soil moist, wait for the seeds to germinate before giving it fertilizer, to help its seedlings grow.

Walnut trees need to be pruned at a good time. Spring pruning is the pruning of walnut trees after germination and before the leafing of walnut trees, this time of pruning is suitable for unfruitful trees or overgrown trees, which can control growth, weaken the tree, and bear fruit earlier.

Trees that are not suitable for pruning in the early fruiting stage will cause injury flow, nutrient damage and weaken the tree. Summer pruning is mainly light pruning, which is suitable for pruning walnut trees that grow too vigorously and do not bear fruit.

Autumn pruning is carried out after the walnut harvest and before the leaves turn yellow, and can be selected from mid-September to early November, which is suitable for pruning weak and old trees. It is best not to prune walnut trees in winter to avoid wounds.

Soil, fertilizer and water management:

The main ways to improve soil conditions are deep ploughing, soil and water conservation, and weeding in tillage. Each deep ploughing should be spaced between one year or half a year.

Weeding loosening plays an important role in the growth of young trees, and weeding loosening needs to be done several times a year. It needs to be combined with the amount of precipitation and grass in that year. Weeding should follow the principle of "weeding should be removed, weeded after rain, and weeded after irrigation".

The amount of fertilizer needs to be combined with the growth of walnut trees and the objective problems of the soil, so as to determine the variety and quantity of fertilizer. The correct selection of fertilizer types plays a very important role in the growth of walnut trees, and the selection of appropriate fertilizer varieties plays a very important role in improving the quality and quantity of walnuts.

Summary. Hello dear <>

The pruning method of old walnut trees is as follows: the crown of the old tree gradually shrinks, the amount of fruit decreases, and the main trunk needs to be cut off completely, so that the plant can re-ger-sprout branches and cultivate as the main trunk branches. In addition, it is necessary to replace the weak backbone branches with newly germinated long branches to form a new crown, and after pruning, apply shadium agent to the wound to help the walnut tree regain growth.

Hello dear <>

The pruning method of old walnut trees is as follows: the crown of the old tree gradually shrinks, the amount of fruit decreases, and the main trunk of the old tree needs to be cut off completely, so that the plant can re-ger-geren branches as the main trunk branch cultivation forest belt. In addition, it is necessary to replace the thin trunk branches with newly germinated branches to form a new crown, and after pruning, apply shadant to the wound to help the walnut tree to regain growth.

Walnut is a walnut plant, walnut kernel contains abundant protein, fat and carbohydrates, and contains calcium, phosphorus, iron and other trace elements and minerals necessary for human beings, as well as carotene, nuclein and other vitamins, with the effect of benefiting the heart, enhancing brain function, improving digestive system function and so on. <>

1. Pruning at the young tree stage: cut off the weak branches on the crown of the walnut tree, and pluck the top of the long branches to promote the germination of new branches. 2. Adult tree pruning:

Cut off the drooping branches under the main branches and side branches, and thin the cross-branches, dense branches, and overlapping branches. 3. Pruning of old trees: cut off the main trunk, re-cultivate the main trunk branches, and form a crown with newly germinated long branches.

1. Pruning at the young tree stage

When pruning the walnut tree in the young stage, the thin branches growing on the crown should be cut off from the base, and then the long branches will be topped to promote the germination of the plant.

2. Adult tree pruning:

The crown of the adult tree has been formed, at this time, the drooping branches that grow under the main branches and side branches should be cut off to reduce the consumption of nutrients, and the retracted branches, cross branches, dense branches, and overlapping branches should be thinned to improve the air permeability between plants, and the aging and weak branches should be cut off to retain the branches with good growth.

3. Pruning old trees

The crown of the old tree is gradually shrinking, the amount of fruit is reduced, and the main trunk needs to be cut off completely, so that the plant can re-ger-ger-sprout branches as the main trunk branches, and the new germinated branches should be used to replace the weak backbone branches to form a new crown, and after the pruning is completed, fungicide should be applied to the wound to help the walnut tree recover its growth.

Pruning walnut trees should be done during the growing season, and try not to prune them at other times, as pruning during the dormant period will accelerate the loss of water and nutrients, which will speed up its death.

Walnut tree pruning should cut off part of the annual branches, followed by cutting off the extended branches of the side branches, cutting off some of the perennial or attacking branches, and then pruning the branches that are too dense to grow properly.

Pruning can be done from the bottom of the branches, and when the long branches germinate, they should be cut off in time. In addition, it is necessary to cut off the cross branches and overlapping branches, and some branches are very thin due to lack of light, so they should also be pruned off.

Walnut is one of the nut foods loved by the people, and it is also one of the world's famous "four dried fruits", rich in nutrients. Therefore, it is now widely cultivated all over the country, so in the process of maintenance, if you want it to bear good fruit, pruning is very important, so how to prune walnut trees? Let's take a look.

1. Pruning in early summer. Since walnut trees, like grapevine changes, have a period of injury, if the spring pruning is not the right time, it is easy to cause the loss of sap from the branches of the tree after pruning, resulting in the death of some branches or even the whole plant. Therefore, the best time to prune should be during the summer solstice in early summer.

2. Autumn pruning. The second pruning should be between late August and early September. At this time, cut off 1 3 or half of the sprouting branches.

The remaining shoots will be more full in the next two months, and when the buds germinate again in the spring of the following year, they are likely to have small walnut fruits.

Walnut trees are not suitable for winter pruning, especially some walnut trees that are beginning to bear fruit, the bud points are already very full in late autumn, and many branches will have flower buds, so avoid winter pruning, which will also avoid the flower buds being cut off. Unless some plants grow a lot of shoots in the inner chamber during the summer. In order to strengthen the ventilation and light transmission of the plant, these excess branches can be thinned off in winter, and the other branches to be retained, the branches are generally not pruned.

Pruning is a particularly important part of the growth of walnut trees, through the reasonable pruning of walnut trees, not only can regulate the distribution of nutrients in the tree, but also can solve the contradiction between vegetative growth and reproductive growth, so as to achieve the purpose of balancing the tree potential, early fruiting, and abundant yield. Let's take a look at the time and method of walnut tree pruning, as well as the pruning techniques of walnut trees of different ages.

Walnut tree pruning time walnut tree and other fruit trees pruning time is different, the pruning of other fruit trees is mainly for the dormant period, supplemented by the growth period, but because the walnut tree is pruned in the dormant period, it is easy to cause injury flow, resulting in the loss of tree nutrients, so in order to avoid and reduce the occurrence of injury flow, walnut tree pruning should be pruned in early spring every year after walnut tree germination and walnut harvest to before defoliation, which can greatly reduce the occurrence of injury flow phenomenon caused by pruning.

The main pruning method of walnut trees1. Stubbing and retraction

Stubbing and retraction are the most commonly used pruning methods when pruning walnut trees, stubbing is to cut off a part of the annual branch tip, retraction refers to the stubbing of the perennial branch, the role of both pruning methods is to promote the local growth of the branch tip, promote the growth of more branches. The severity of pruning is different, the reaction is also different, the stub cut should be determined according to the branch position of the cut bud, and the retracted cut position can be selected at the branch of the perennial branch with forks.

Second, topping and cutting

The effect of these two pruning methods can inhibit the growth of the branches, avoid excessive nutrient consumption, provide sufficient nutrients for the flowering of fruit trees, improve the fruit setting rate of fruit trees, and promote the flower bud differentiation and flowering and fruiting of other fruiting branches.

3. Wipe buds and thin shoots

Budding refers to wiping off the shoots of the branches by hand or pruning tools, and thinning the shoots is to comb off the overly dense branches when the new shoots begin to grow vigorously, and the role of these two pruning methods is to save and retain nutrients, and provide sufficient nutrients for the retention of shoots and new shoots, so that the buds or new shoots grow more fully. By wiping buds and thinning shoots, light and ventilation conditions within the canopy can also be improved, resulting in improved fruit quality and yield.

Fourth, thinning and slow release

Thinning is a method of cutting off the branches from the base, mainly used when the branches grow too densely, through the thinning of the branches, it can greatly improve the ventilation and light transmittance in the canopy, and promote the formation of flower bud differentiation. Slow release refers to throwing the branches without cutting them, allowing the buds on the branches to grow freely, the main role is to slow down the growth of the branches and promote the growth of axillary flowers on the branches. When the shoots are slowly released to form flower buds, it is necessary to properly retract and thinn the pruning, if the branches have space to grow, if there is no space for more branches, the branches should be repaired.

Fifth, pull branches

Pulling branches refers to pulling away the backbone branches with a small growth angle, which can not only achieve the appropriate angle of branch opening, but also have a slowing effect on the growth of branches. Pulling branches is generally carried out in early spring when the sap of the tree begins to flow, and the tips of the branches are pulled to a suitable angle with a traction such as rope or wire, and a soft cloth can be placed on the part of the branch to avoid damage to the bark when pulling the branches.

We should cut off the smaller shoots that it grows on, then keep its main trunk and auxiliary trunks, and cut off all the other trunks, and prune the withered and yellowed parts of it.

Prune its minutiae and be sure not to remove its flower bones, otherwise it will affect its fruiting rate.

Follow the shape. Take your own scissors and trim them carefully according to the image in your head.

Pruning time, walnut tree pruning should be carried out during the growth period, not during the dormant period; Cut off some of the two-year-old branches, and on the other hand, cut off the extension of the secondary shoots, and cut off the parts of the multi-year branches; Combing work, to cut off the cross branches, overlapping branches; After fruit pruning, the dense branches should be immediately thinned in accordance with the basic principle of removing the weak and retaining the strong.

Walnut pruning should be done during the growing period, when the plant is in good condition to promote the concentration of nutrients, and should not be pruned during the dormant period, or after harvest and before the leaves turn yellow, so as to promote growth.

Walnut tree pruning involves cutting off some of the two-year-old branches, and on the other hand, cutting off the extension of the secondary branches, cutting off the parts of the branches that have grown for many years, and then pruning the branches that are too overgrown.

In the case of good growth of walnut trees, you can also carry out pruning through the bottom of the branches and leaves, in the case of sprouting long branches, you should cut off first, in addition to cutting off the cross branches and overlapping branches, some branches and leaves are very thin and thin due to lack of light, and they also need to be cut off.

Thin the dense branches and solve the dorsal branches. The large number of branches of early walnut trees can easily lead to many branches in the crown width and too much relative density, which seriously affects the natural ventilation and light transmittance. For this reason, dense branches should be immediately thinned in accordance with the basic principle of removing the weak and retaining the strong.

Cut off after budding or before branch elongation.
