How should the branches be pruned so that it has a higher survival rate?

Transplanting shrubs is generally done with bare roots, so it is inevitable to damage some of the roots during the transplanting process. In order for the newly planted seedlings to survive and resume growth quickly, it is necessary to prune the aboveground parts appropriately to reduce water transpiration and maintain the balance of water metabolism in the upper and lower parts of the plant. The main purpose of pruning the transplanted shrubs is to keep the plants high inside and low outside, and the natural plump spherical shape, so as to achieve the purpose of ventilation and light transmission and vigorous growth.

There are several main methods of pruning shrubs for transplanting shrubs:

1. Thinning branches. The diseased branches, over-dense branches, cross branches, and overlapping branches in the crown bush should be thinned from the base. For the clumping tree species with developed root tillers, such as yellow thorn plum, rose, pearl plum, bauhinia, etc., the old branches should be thinned more to make them constantly renew and grow vigorously.

For cloves that germinate early in early spring, only sparse or slightly shortened.

Second, tillering. Cultivating shrubs with trunks, such as peach, forsythia, crape myrtle, etc., should be transplanted by cutting off the tillers that germinate from the roots to avoid water loss.

3. Stub. 1.In order to improve the survival rate of shrubs that bloom on the branches of the alternate year in early spring, such as elm leaf plum, peach, spring welcome, honeysuckle, etc., it is necessary to keep 3 to 5 suitable main branches and the rest to be thinned.

About half of the main branches should be shortened, and about two-thirds of the weak branches should be thinned out of the side branches.

2.Shrubs that bloom in the current year, such as crape myrtle, hibiscus, rose, yueji, meadowsweet, pearl plum, etc., should be re-pruned after transplanting. Two-thirds of the retained branches can be cut off in order to concentrate nutrients to promote the growth of new branches, so as to achieve the purpose of more flowering and large and gorgeous flowers.

3.Shrubs that are both flowering and fruiting, such as goldenrod, bone, and water xundrium, are only cut off from one-quarter to one-fifth of the branches.

4.For ornamental branches, such as French holly, begonia, red ruimu, etc., the branches need to be re-pruned to promote the growth of new branches, because the new fresh shoots are more ornamental.

Fourth, pick buds. For some precious shrub species, such as magnolia, if there is too much flowering in the year after transplantation, it will over-consume nutrients and affect survival and growth. Therefore, the flower buds should be removed after transplanting, and the branches should be lightly pruned to ensure the survival of seedlings.

After cutting off the new side branches that grow out of the excess, leaving the main trunk and thicker branches, and less absorption of water and nutrients, the branches will grow rapidly.

Cut off some broken or yellowed branches. Because if you don't prune, other branches will not have enough nutrients, and those bad branches will absorb nutrients, so you should prune the branches properly so that it does not have a reduced survival rate.

Stubbing can improve the survival rate, retain two-thirds of the main branch, avoid nutrient loss caused by less flowering, and be more conducive to growth.

If you want to survive the branches cut from the tree, you should choose strong branches with apical buds, which can be propagated by cuttings. Cut off the excess leaves on top, prune and soak in the rooting solution for 20 to 30 minutes.

Choose soft, well-permeable soil, after preparation, the treated cuttings are inserted, about two or three centimeters deep into the soil, watered thoroughly after insertion, maintained in a ventilated and warm place, and the environment is suitable for rooting faster.

How to feed the branches:

Trees have a strong ability to regenerate and can be propagated by cuttings, making them relatively easy to maintain. For branches cut from trees, choose strong branches with apical buds as cuttings and prune off their excess leaves.

1. After pruning the cuttings, they can be soaked in the rooting powder solution for 20 to 30 minutes, and the sea Wolgen rooting agent can be selected, which is conducive to the rapid rooting of the cuttings and improves the survival rate.

2. After soaking the cuttings, it can be dried in a cool and ventilated position, and after the wound is healed, it can be propagated by cuttings. Trees are more adaptable, and loose, permeable and well-drained soil can be used as a medium. Dry cuttings are cut in loose and breathable soil to a depth of 2-3 cm.

3. After cuttings, an appropriate amount of water is needed to provide sufficient water for the cuttings to grow. If cuttings are carried out during the dormant period, after cuttings, a layer of film can be covered on the surface of the pot, which has the growth of heat preservation and humidification. After cuttings, the cuttings can be cured in a cool and ventilated environment, and the soil should be kept moist during the curing period.

Fourth, after the cuttings take root in the later stage, they can be moved to a sunny environment, and the environment should be kept ventilated. During the maintenance period, the cuttings should also be given sufficient water and fertilizer to facilitate the germination of branches.

Branches also need to be sprayed regularly with carbendazim in their later adulthood.

and so on to prevent insect pests.

Summary: Branches cut from trees, selected branches with strong apical buds, can be propagated by cuttings. After pruning, the shoots can be soaked in a rooting powder solution and dried.

After drying, the shoots can be cut into loose and breathable soil, and water needs to be controlled during maintenance. In the later stage, after the cuttings take root and germinate, they can be given sufficient light, water and fertilizer.

The best time to prune the trees is in March to April in the spring or August to September in the fall.

When pruning trees, it is best to do it in March and April in the spring or August to September in the fall, because the temperature and humidity at this time are more suitable and conducive to the recovery of the tree.

Pests and diseases are less likely to occur, making it easier for trees to recover, but the exact pruning time will depend on the local weather conditions. When we prune the branches, we should be moderate and do not cut off the good branches, which will also affect the growth of the next year.

Tree pruning methods

When pruning trees, it is necessary to prepare a pair of sterilized scissors to cut off the branches and diseased branches of the plants with poor growth, so that the strong side branches can germinate in the next year, and the branches and leaves that are too dense should be cut to improve the light transmission and ventilation between the plants and maintain the normal growth of the trees.

After pruning the tree, the diluted potassium permanganate solution should be sprayed on the fracture of the branch to disinfect and sterilize, and then the wound of the tree should be smeared with plant ash to speed up the healing of the wound of the plant, and then the wound of the tree can be wrapped with plastic film to avoid the wound from rotting in water.

When maintaining trees, it is necessary to control the frequency of watering, which can be watered according to the weather conditions, when the environment is too dry, it is necessary to water every 10 days and the soil should be completely watered, and during the rainy season, it is necessary to drain the water in the soil for the trees to avoid rotting the root system of the plants.

1. Slotting bed, cuttings can be adapted to local conditions, all kinds of basins, wooden boxes, plastic boxes, fish tanks, etc.

2. Preparation for cuttings, the lower part of this kind of container should be padded with drainage materials when making a slotting bed, and less can be put if there are holes or cracks at the bottom for drainage. Some greenhouses have brick cuttings, which can be cut with a little tidying. Sometimes, in order to rescue diseased plants, it is necessary to use cuttings in any season, and it is necessary to use cuttings with a bottom temperature.

The heat source is buried in the substrate with a heating wire or electric heater, so that the temperature of the substrate is 3-6 times higher than the air temperature, so that the rooting is faster. Some species that are easy to root, such as the longevity flower of the Sedum family, and some species of the cactus family that are used as rootstocks, can be inserted directly into the sand in greenhouses or plastic greenhouses.

3. Substrate, the cutting substrate used in general types requires loose aeration, does not contain uncooked organic matter, and does not contain salts. Commonly used are river sand, vermiculite, perlite, plain sandy soil, peaty soil, decaying moss, chaff ash and sawdust. No matter what kind of substrate should be clean, uniform particles, medium size, the substrate in the slotting bed should generally not be spread too thick, otherwise it is not conducive to the temperature of the substrate and affect rooting.

After the scion of the grafted plant is formed, it is sometimes necessary to take it from the rootstock and cut the roots, and you can use a pot slightly larger than the plant to cut a single plant.

Frequent pruning of the branches of the plant is good for the plant. The growth of plants depends on auxin in the plant, and auxin only promotes the growth of the top and inhibits the growth of the next branches, so that their growth is not good, so pruning the branches of the plant can ensure the healthy growth of the plant.

Trees rely on the roots to absorb water to ** leaves, trees in the process of transplanting will inevitably damage some roots, affecting the absorption of water, leaves also evaporate a lot of water, so that the transplanted trees are easy to die.

In order to improve the survival rate of transplanted trees, people prune the leaves of trees a lot to reduce water evaporation and improve the survival rate.

In order to improve the survival rate of transplanted trees, people prune the leaves of trees a lot to reduce the evaporation of water and improve the survival rate.

Expansion:

First, the pruning time of the winter pruning of garden trees should vary according to the climate of each region, generally from late autumn to early spring of the following year, that is, in the dormant period before the flow of sap can be pruned, and the most suitable pruning is between one or two weeks after the tree leaves fall and one or two weeks before germination. Tree species with poor cold resistance, such as tulipwood and eucommia, should be pruned in early spring to avoid frost damage to wounds; Tree species with injured flow, such as grapes, plane trees, kiwifruit, compound leaf maple, etc., should avoid the injured flow period, do not prune too late, and should finish pruning before the end of January.

Second, the pruning method.

1. .Pruning: Pruning is the main technical measure in pruning, which is usually done in winter. Pruning can be divided into two categories: "thinning" and "stubbing" according to the way of pruning.

Pruning: Cutting the entire branch from the meristem (i.e., the base of the branch) is a pruning method to reduce the number of branches. Thinning is often combined with stubbing to improve the dense growth of branches caused by stubbing pruning.

In addition, thinning is conducive to the growth and development of internal branches, adjusting the uniform distribution of branches, improving ventilation and light transmission conditions, and the cutting mouth should be flush with the raw branches. For rotating branches, some branches should be thinned first, and then the rest of the branches should be thinned after the wound has healed.

Stubbing: A pruning method in which only a part of the branch is cut off and the basal branch is retained. According to the degree of stubbing, it can be divided into light stub, medium stub and heavy stub.

Light stubbing is the top tip of the branch that is lightly pruned, which is mainly used for pruning the strong branches of flower and fruit trees; The middle stub is stub above the full bud in the middle and upper part of the branch, which is mainly used for the rejuvenation of local weak branches; Heavy stubbing, that is, stubbing the upper part of the full bud in the middle and lower part of the branch, is mainly used for the rejuvenation of old and weak branches and old trees, and can also be used for the pruning of hibiscus, purple-leaved plum and crape myrtle. The cut should be beveled and smooth. The position of the cut from the bud should be on the bud to centimeters.

For naturally growing shade trees, light pruning, such as proper thinning of redundant branches, can promote tree growth. For senescent trees, heavy pruning can rejuvenate and rejuvenate the tree, making the tree shape more balanced and beautiful.

2.Cutting off dry stems or thick main, side, and backbone branches can promote tree regeneration and rejuvenation. For the thicker trunks of garden trees, pruning shears cannot be used, and hand saws are usually used.

When sawing large branches and side branches, in order to avoid splitting the saw edge, you can first cut all the edges from the bottom of the branch to the base of the branch slightly to determine the position of the saw edge, and the depth of the cut is 1 3 to 2 5 of the thickness of the branch, and then above the corresponding position of the saw edge, sawed from top to bottom.

After cutting off the large branches, the wound is large and the surface is rough, and finally the wound should be cut and smoothed from the base of the branch with a sharp knife, and the wound should be coated with a wound protector or sealed with wax, or a plastic sheet should be bandaged at the wound to avoid pests and diseases and water loss, and it is conducive to the healing of the wound.

These branches are cut to make the tree grow better, and the branches that are cut are broken, dead or diseased, and they are cut to keep the tree healthy and beautiful. ”

Trees do not need to be pruned, pruning is purely idealistic and supervisor-based thinking, pruning belongs to the seedlings to grow, it will only backfire and be self-defeating!

This can be more aesthetically pleasing, and it can also reduce unnecessary nutrient consumption of the tree.

Cut off these branches.

In order to make the tree grow better (lush), these branches that are cut off are almost versions.

Broken, dead or diseased branches, the tree will not be good after cutting, and the tree repair and pruning will be more beautiful, you can't let others grow casually, sometimes when it rains and the wind blows, the tree that is about to break may accidentally injure people, and is not responsible for people's safety. And if you don't prune it, those bad trees may die, so the trees should be pruned.

If there is a tip effect on the organism, the apical bud will grow first, but the side bud will be inhibited, so the apical bud should be pruned to let it grow luxuriantly. There is also the demand for urban greening and beauty.

Let it grow taller and stronger; The fruiting period is used to color the fruit.

For the sake of aesthetics, frequent pruning will cause the tree to grow into a specific shape.

It may also be that pruning will cause the tree to grow faster.
