Why pruning and removing leaves is good for the survival of newly planted trees

Why should flowers be pruned?

The proverb that "seven points rely on management, three points rely on cutting" is an important experience in raising flowers. Through pruning, not only can the flower branches be evenly distributed, nutrients can be saved, the plant potential can be adjusted, and the growth can be controlled, so that the flower plant shape is neat and beautiful, and more importantly, it is conducive to more flowering. The flowers of most flowers bloom on new branches, and only by constantly pruning old branches can new branches be promoted, more flowering, and more fruiting.

Pruning is generally divided into the following two types: (1) dormant pruning. It is mainly thinned and truncated.

It should be done in early spring when the sap is just beginning to flow and the buds are about to germinate. If the pruning is too early, the wound is not easy to heal, and the bud germination and new shoots are susceptible to frost damage; Pruning too late, new shoots have germinated, wasting nutrients. (2) Pruning during the growing season.

It is mainly to regulate vegetative growth, including topping, budding, flower thinning, fruit thinning, and pruning long branches. During the growth period, at any time to the right to proceed.

To put it simply, it was to slow down his water dispersion.

Improve survival rate!There are more leaves and books, less water is absorbed, and more consequences can be imagined!

Because there is auxin on the tip of the leaf, it is easy to fork! Affect the aesthetics! Not conducive to the growth of the main branches! `

This is because it allows nutrients that are not necessarily lost to be used in useful places.

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.

During the growth period of plants, the growth and development of plants are artificially controlled, and various techniques for modification and arrangement of plants are called pruning and pruning. Pruning is to control the growth of young trees by manual pruning, and to reasonably allocate and cultivate backbone branches in order to form a good tree structure and crown width. Pruning is a management measure that reasonably adjusts the nutrient distribution in the tree and the growth potential of branches on the basis of soil, fertilizer and water management, according to the natural conditions, growth habits and production requirements of tree species. Through pruning and pruning, the ventilation and light transmission conditions can be improved, the assimilation effect can be strengthened, the plant resistance can be increased, and the damage of diseases and pests can be reduced. At the same time, it can reasonably regulate the operation of nutrients and water, reduce the useless consumption of nutrients, enhance the physiological activity of all parts of the tree, and restore the vitality of the old tree, so that the plant can develop in accordance with the direction of human needs, and continuously improve the quality and yield of products.

Pruning of medicinal plants includes pruning and root pruning. Pruning is mainly used for woody medicinal materials, but some herbaceous plants should also be pruned, such as the main vine of melon root flowering and fruiting late, the side vine flowering and fruiting early, so the main vine should be removed and the side vine should be left. Different medicinal plants and different ages of the same medicinal plant have different requirements for pruning.

Generally, for woody plants such as cinnamon, eucommia, magnolia bark, etc., the erect and stout trunk should be cultivated, the lower premature branches and weak branches should be cut off, and the woody plants with fruit seeds should be properly controlled, the number of branches should be increased, and attention should be paid to adjusting the subordination of the main and side branches at all levels to promote flowering and fruiting. Young trees should generally be lightly pruned to cultivate a certain plant shape, such as conical, cup-shaped, tower-shaped, umbrella-shaped, etc., to promote early formation and early yield. However, for some shrubs, such as wolfberry, rose and other young trees, it is advisable to re-prune.

For the pruning of adult trees, thinning and stubbing are often used to maintain the robustness of the tree and the relative balance between various parts, so that strong and full vegetative branches and fruiting branches can be extracted every year to improve the ability to set fruit. For senescent plants, emphasis should be placed on the renewal of shoots to restore tree growth and fruiting. The pruning time is generally in winter and summer.

Winter pruning, mainly pruning the main and side branches, pruning diseased branches, dead branches, delicate branches, etc.; Summer pruning, mainly to remove buds, shoot picking and topping, etc. Root pruning is only carried out in a few medicinal plants, such as Aconitum aconitum (aconite) to prune too many lateral tuberous roots, so that the remaining tuber roots grow hypertrophied to facilitate processing; Peony prunes remove lateral roots to ensure hypertrophic growth of taproots and promote increased yield.

Technical measures to prune a part of the vegetative organs of fruit trees in order to adjust the canopy structure and renew the composition of branches.

Purpose and function The crown of fruit trees expands with the growth of tree age, and too many branches and leaves will inevitably cause the consequences of dense outer and hollow inside, premature aging of the tree, serious size and size, and reduction of fruit yield and quality. Timely and reasonable pruning can have the following effects: Regulate the reasonable distribution of branches and leaves.

That is, on the basis of shaping, the density of branches and leaves, the distribution direction and the leaf area coefficient of each part of the canopy were adjusted to maximize the effective photosynthetic area of the canopy. Regulates growth and fruiting. Makes vegetative growth normal and not overgrown; Moderate flowering, fruitfulness without weakening the tree; At the same time, it can prevent the early aging of fruit trees and renew and rejuvenate in time.

Adjust the proportion of branch composition. The growth period of short branches is short, the consumption is small and the accumulation is early, but the leaves are few and the total photosynthetic amount is low. The vegetative branches have a long growth period and consume more, but they also accumulate more in the later stage. Different tree species and tree ages require corresponding and appropriate branch proportions, so that the operation, distribution, consumption and accumulation of nutrients in the tree during the annual growth cycle can be coordinated according to the normal growth and reproductive rhythm.

This can be achieved by pruning. Pruning also balances the growth potential between groups of plants and between the main branches on a plant, resulting in balanced yields and easy management. In addition, pruning is also a means of harmonizing the growth of the aboveground part with the root system.

How do you prune the branches before transporting?

Trim before transport, should be lightly cut. Prune young branches and leaves, prune and expand branches and leaves, prune branches and leaves of diseased insects, and prune off closed branches and leaves.

After excavation, secondary pruning is carried out to remove split branches and broken branches.

Prune no more than 1 3 branches and leaves (the reason is that it is necessary to prune again when planting. ）

After pruning, "Happy Forest Callus Cream" should be applied to the pruning wound as soon as possible when the non-injury fluid flows out, so as to promote wound healing and seal the wound to reduce water evaporation.

For evergreen trees and trees that are more difficult to germinate new branches, try not to prune the branches and remove only part of the leaves.

How do you prune the branches before planting?

When planting after unloading, the branches and leaves should be pruned in place, which is also the last pruning before planting.

When pruning, culture branches should be left for the rapid formation of the cultivation canopy.

For evergreen trees and trees with weak germination, try not to prune the branches and remove only part of the leaves.

After pruning, the pruning wound hygiene should be maintained, and the "Happy Forest Callus Ointment" should be applied in time to protect the wound and promote wound healing.

For tree species that are easy to germinate and sprout, crown transplantation can be carried out, and transplantation of main trunk branches can also be left.

Different methods should be adopted according to the different forest species and tree species, and the difference in afforestation density and afforestation purpose.

When afforestation of coniferous tree species, residual branches, dead branches, and multi-headed branches can be pruned, and only one upright branch can be retained. After afforestation, 5 15 years after pruning the overly dense branches, pruning the side branches for 1-2 rounds, every 4-5 years. Poplar trees are used to create shelterbelts and timber forests, and the central branches on the main trunk should be selected as the leading branches in time, and the competing branches should be removed in time, and the side buds should be picked and fingered, and the excess side branches should be trimmed to promote the growth of tall and thick.

The pruning of trees in urban and rural greening and urban greening communities should pay attention to the beautiful and generous tree shape, unique style, and suitable for ornamentation. For the willow trees that have been truncated, they should be purposefully cultivated into a "four-sided bucket" or "three-strand brace" shape, and avoid the "material branch" shape with two main trunks.

Trim the incision to be smooth and prevent wall cracks. The stubble height should be 1 cm - 2 cm. Too high or too low will affect wound healing and tree growth.

The pruning season is preferable in early spring or late autumn and winter. Early spring is preferable before the sap flows. If the tree is pruned when it sprouts, the water of the tree will transpirate quickly, lose water, and consume more nutrients, which is not conducive to the growth of the tree.

Some fast-growing tree species, such as poplar and willow, can also be pruned in summer. However, be careful not to prune on rainy days to avoid soaking the wound with water and contracting the disease.

Pruning should pay attention to "pruning in winter and controlling the side in summer". That is, in winter, strong trees should be pruned heavily, weak trees should be pruned lightly, and the upright and strong competitive branches should be pruned from the base. In summer, the strong and vigorous branches are controlled, the strong and the weak are controlled, the tree potential is adjusted and balanced, and the principles of strong side heading, strong branches are pruned, weak branches are lightly pruned, and small branches are left more, so as to achieve the purpose of highlighting the main trunk and promoting the pruning of trees to accelerate growth.
