Why do fruit trees pull branches?Why do fruit trees pull branches?

Because pulling branches on fruit trees can adjust the growth of fruit trees, promote flowering in the next year, and also help to fix the shape of fruit trees. Therefore the fruit tree should pull its branches.

Branch pulling is an important part of fruit tree production management, which is used to improve the light conditions of the tree, inhibit the vegetative growth, promote the reproductive growth, reduce the nutrient consumption of the tree, regulate the balance of vegetative growth and reproductive growth, promote the formation of flower buds, and reduce the occurrence of the annual phenomenon of fruit tree size, which is an important measure to ensure high quality, high yield and stable yield.

This is because the nutrients in the soil are better transferred to the tips of the branches, which helps the fruit trees to grow well.

Why does loquat bloom and not set fruit?

<> reasonable pulling of fruit trees can adjust the growth of fruit trees in time, which is conducive to the spring shade of branches to receive light and improve the amount of fruit setPulling branches on fruit trees is conducive to the accumulation of nutrients, which is convenient for promoting flowering in the next year;Pulling branches of fruit trees is conducive to fixing the round shape of the tree and meeting the requirements of intensive planting.

Dear, hello, I am very happy to answer your questions, I have found for you: now fruit trees can pull branches or stuffy can be fruit trees The time of fruit tree pulling varies depending on factors such as fruit tree species, region and climate. After the new shoots grow in the spring, the fruit tree enters the growth period, which is a suitable period for branch pulling.

If it is a fast-growing fruit tree, such as citrus, lychee, etc., you can also carry out appropriate branch pulling during the growing season to help control the branch growth and morphology of the fruit tree. It is recommended that you understand the characteristics and methods of the relevant fruit trees before pulling the branches to ensure that the operation is correct and avoid the impact on the fruit trees. At the same time, we should also pay attention to protect the health and growth of fruit trees I hope mine can help you, if you are satisfied with my service, please give a thumbs up, I wish you all the best!.

Shaping and pruning of apple trees, pulling branches and opening corners is one of the most commonly used fruits by fruit growers. Artificially changing the growth direction of the branches, so that the upright growth branches become oblique branches, horizontal branches or weeping branches, can effectively regulate the growth of apple branches, promote the formation of short branches, promote the transformation of vegetative growth to reproductive growth, and early flowering and fruiting. Now the time and method of pulling the branches are simple as follows

The best time for apple trees to pull branches should be in June, after the spring shoots stop growing, after the fruit grower fertilizes the apple tree. At this time, the temperature is higher, the apple tree branches are soft, and the back is not easy to remove, and the pulled branches can quickly meet the requirements, and it is also more conducive to the formation of flower buds.

In fact, spring, summer, autumn can pull branches, compared to the summer pull the best, followed by autumn to pull branches, spring to pull branches, branches are more brittle and hard, not easy to pull, but also more difficult to shape, and the back is easy to pull strips, so it is best not to pull branches in spring. The method of pulling the branch of the apple tree can be adopted: the method of "one push, two kneading, three pressing and four positioning", "one pushing and two kneading" is to grasp the root of the branch, and repeatedly push and knead it back and forth to make the branch soft; The "three pressures" are to gradually press the branches down to the desired angle on the basis of pushing and kneading; The "four positioning" is to achieve the required angle, and the branches are tightened and fixed with ropes.

For those thicker branches, the branches that are difficult to push and pull, you can take the back of the base, and even you can see the three saw lanes to reach the angle that needs to be pulled, the depth of the saw should be about 1 3, the saw spacing is about 3 cm, and then press to fix.

The angle of the apple tree can be determined according to the tree species of the apple tree and the specific tree shape requirements. Generally speaking, permanent main branches can be pulled to about 95 degrees to 100 degrees, temporary twigs and auxiliary branches, pulled to about 100 degrees to 110 degrees as well, for the branches on the main branches, can be pulled to a natural drooping state, promoting the rapid formation of flower buds, flowering and fruiting.

In short, apple trees can change the regulation of tree potential by pulling branches, promote the reproduction and growth of apple trees, and form flower buds as soon as possible. There is no fixed model for the specific time of pulling branches, the method of pulling branches, the angle of pulling branches, etc., fruit farmers according to the specific situation of their orchards, as well as the way of doing business, as long as the apple trees can achieve strong growth and harvest, fruit farmers can improve their economic income, is the best. /n/n

During the growth period of the apple tree, the branches must be pulled according to the different varieties, and the angle must be confirmed according to different varieties, and the amplitude of stretching also needs to be adjusted accordingly, and in the process of drawing, the correct steps must be adopted, and the branches should be accurately lifted by hand, so that the branches remain soft and not crushed.

Hold each branch and pull hard so that the branches have different angles and stretch the branches, so that the apple tree can grow well.

It can improve the permeability of the canopy. After reasonable branch pulling, the top advantage can be broken, and the backbone branches of the apple tree can grow flatly, and the branches can be distributed in an orderly manner, which improves the permeability of the canopy inner hall, opens the optical path, and increases the photosynthetic area, thereby enhancing the photosynthetic efficiency of the canopy and improving the quality of apples. The characteristics of apple trees are that when they grow upright, they have vigorous vegetative growth, strong branching ability, weak reproductive growth traits, difficult to form flower buds, and late fruiting.

Only the pain of pulling the branches, reduce the vegetative growth force, and promote early flowering and fruiting.

After the orchard is mulched, the evaporation of ground water decreases, and the soil moisture is relatively increased, especially in mountainous and dry thin land, the effect of lack of fruit orchard is significant, and in normal rainfall years, the grassland orchard can be basically protected from the impact of drought. In the natural state of fruit trees, the apical and vertical dominance promotes the upright and small angles of the branches, which is conducive to easier exposure to sunlight and conducive to the vegetative growth of rhizomes and leaves. During the growth process of apple trees, the branches generally grow upright and upward, and will be disorganized, the canopy in the tree hall is not smooth, the light and air permeability are poor, and the tree shape is not ideal, which requires us to prune and pull branches to strengthen the management of fruit trees.

The important role of pulling branches is to increase the expansion angle of branches, generally reaching more than 90 °, so that the number of upright branches can be significantly reduced after operation, so as to form a hierarchical distribution of branches, which does not affect each other ventilation and light transmission, and can also increase the effective photosynthesis area, improve the photosynthetic efficiency of the inner chamber of the canopy, the middle and lower leaves, and improve the fruit quality. Apple tree branch pulling is also a work item in the management of fruit trees, through the branch pulling operation to change the original growth direction of the branch, so that it grows in the direction of artificial pretensence, can enhance the tree potential, promote flowering, improve the light conditions, so that the crown structure is more comprehensive and reasonable, is conducive to the normal growth of fruit trees.

In the natural growth environment, apple trees tend to have a small branch development angle, which is easy to lead to the crown not opening, the internal space is small, the number of fruiting branches that can accommodate is small, and the yield per plant is relatively low. The canopy area can be significantly increased by pulling branchesObjects: Branches suitable for pulling branches: The branches suitable for pulling branches in medium-density gardens should be more than 1 meter in length and more than 1 cm in base thickness, and should not be too early.

If it is pulled too early, it is easy to cause the tree to weaken and form a "small old tree".

When pulling branches, we must pay attention to the growth of apple trees, and at the same time, we should also pay attention to the protection after pulling branches, and pay attention to the operation process of pulling branches.

This is more conducive to the growth of apple trees, is good for apple trees, and is also convenient for fruit trees to pick, which can play a good effect, so that apple trees can harvest more fruits, so that the number of apples no longer grows very high, saving nutrients and nutrients.

In fact, we can use some force, and then fix the apple branch in one direction, so that the apple tree grows in one direction, so that it can play a good role.

It is enough to pull the apple branches normally and naturally, so that the apple tree can grow very well.

After pruning the fruit tree, rub some of the branches upwards to soften them, and then find a good angle to fix them with wire or rope.

It is very important to pull branches from apple trees, how to pull branches from apple trees? As one of the important links in the process of apple tree shaping and pruning, branch pulling plays an important role in easing tree momentum, promoting flowering, improving light and improving fruit quality. 1.

The best time for apple pulling is in late spring and early autumn, about after the fruit tree germination and in August-September. 2.The angle of pulling branches, firstly, is determined according to the growth potential of the tree, if the branches grow vigorously, the pulling angle should be large, on the contrary, the growth of the branches is weak, and the pulling angle of the branches should be small; Secondly, according to the orchard planting density, the orchard with large planting density has the main branch pulling angle of about 110°-120°, and the orchard with small planting density.

3.When carrying out the branch pulling operation, the fruit farmer should follow the branch pulling technique of "one push, two kneading, three pressing, and four positioning", in which "one push" refers to repeatedly pushing back and forth when holding the branch; "Second kneading" refers to rubbing the branches left and right; "Three pressures" refers to pressing the kneaded branches to a suitable angle; "Four positioning" refers to the use of ropes and other means to fix the branches, so that they are straight and not "bow-shaped".

Hello, dear, I've been waiting for you for a long time, fruit tree pruning technology is a model-based pruning technology, which refers to reducing the complexity of the decision tree and improving the accuracy of the decision tree. It is based on the possible overfitting problems in the deciduous tree model, by removing some leaf nodes and corresponding branches to reduce the complexity of the decision tree, omit harmful leaf nodes, and improve the generalization ability of the model. The principle of fruit tree pulling technology is based on the possibility of overfitting the problem of curved answers in the decision tree model, and the information gain and deviation of the nodes are quantitatively analyzed to determine whether the nodes of the decision tree need to be pruned, so as to reduce the complexity of the decision tree and retain the effective information of the nodes.

The branching technique first considers the information gain of the current node, if the information gain is very low, the node can be removed, and at the same time considers the deviation of the node, if the deviation is large, it also means that the node may have a negative impact on the accuracy of the model, so the node can also be removed to reduce the complexity of the decision tree and improve the accuracy of the model.

<> apple trees can be left unpulled, but the trees will not be easy to shape, and will generally lead to late fruiting and low yields. Pulling branches on apple trees in time can take care of the angle of opening branches, ease the tree's momentum, increase the germination rate and branching rate, and improve the light duration of the inner hall of the cave stove; It can also promote flower bud differentiation and improve the yield of filial piety in the early stage of apple trees.

Hello, dear, because of the autumn application of basal fertilizer, the carbohydrates and inorganic nutrients absorbed by the roots become organic nutrients after the transformation of leaves, and they begin to be stored in mid-October, that is, before and after the frost falls. Nutrient storage is first and foremost stored in the branches of above-ground fruit trees, not in the root system. As the temperature drops, the leaves fall off, and the stomata of the bark of the fruit tree continue to close, and the nutrients continue to sink.

Once the average daily temperature drops, the tree becomes dormant, the nutrient cycle stops completely, and all the nutrients in the tree sink into the ground and are stored in the root system. Note that the nutrient cycle stops, which means that the sap no longer exchanges and flows up and down, does not mean that the growth of the fruit tree stops, let alone that the life of the fruit tree stops. It's like sleeping alone doesn't mean that the grandchildren are dead.

Fruit trees in the dormant period in winter, because the underground temperature is higher than the aboveground temperature, so the fruit trees in the winter dormant period. ☺

It is generally not recommended to pull branches for fruit tree branches with thick branches, because the main branches and side branches at this time have grown particularly old and mature, if the branches are pulled, the branches will only be broken, which will affect its normal growth, and if it is serious, it will also affect its yield and quality, so it is generally selected when pulling branches, and the old trees can be pruned appropriately, so as to improve its fruit setting rate in the coming year.

The best time to pull branches is mainly when the branches of fruit trees are still semi-lignified. This time is roughly in August to September of the year, when the branches are in a semi-lignified state, the branches are soft and plastic, the branch angle is easy to stabilize after pulling the branches, the autumn shoots no longer germinate on the back, and can promote nutrient accumulation and flower bud differentiation.

Pull the branches. When the new shoot grows to 20-25 cm, use a toothpick to stretch it out to a horizontal angle between the new tip and the center stem.

Pulling branches is carried out according to the steps of "one pushing, two kneading, three pressing and four positioning".

One push: Hold the branch with your hand and push it repeatedly up and down, left and right.

2nd kneading: Knead the branches repeatedly to soften.

Triple Pressing: While kneading the soft branches, press the branches down to the desired angle.

Fourth, positioning: use the branch rope (nylon grass, rope, branch puller, angle opener) to pull the branches, flatten, stretch, can not be bow-shaped.
