How do you tell if a large sized tree is alive after transplanting?

After the tree is transplanted, a period of time to see whether the buds, the leaves that grow are brittle green and glowing, and the leaves of physical and mental health are all proof that they can get the sun normally, make the plant photosynthesis, and the tree stem can play a role in the absorption and dredging of load-bearing nutrients, and it is basically confirmed that the tree has already survived and began to have new roots. After planting a period of flowers and trees, you can backfill a piece of area, check the condition of the tree stem to stop hair loss, at this time, if you can find that some black hair rhizomes have grown on the tree stem, and the rise is still very abundant, which also shows that the tree is now beginning to renew a new vitality, and gradually devote itself to digestion and absorption of external nutrients, the probability of survival is also very large.

The standard for certifying whether the flowers and trees survive after planting is the natural environment of the four digital clocks of each season throughout the year.

The climate is all different. After transplanting, flowers and trees that have not grown and developed in different types of natural environment and climate throughout the year cannot be certified as surviving. After the tree is transplanted, it must be grown and developed by different types of natural environment and climate throughout the year before it can be certified as a surviving flower and tree.

After transplanting, it is difficult to distinguish the survival of large trees, after all, the trees are large and carry sufficient nutrients.

Even if the rhizome can not survive the growth and development, digestion and absorption of fertilizer water, it is enough to maintain the water and nutrients required by the physiology of flowers and trees branches, showing the situation of "false life", and it will slowly wither and die after a year, and some old trees can even maintain 2-3 years of "false life", therefore, in the short term, it is difficult to distinguish 100% whether the transplanting of large trees is alive or not. Before planting, the branches must be shortened, the summer planting must do off the leaves, reduce evaporation, after planting generally more than half a month can know whether to survive or not, if you see the budding then proves that it has already lived, but sometimes although the sprout is not necessarily alive, there are no sprouts at all, flowers and trees do not know whether they have died or are alive, at this time you need to go to the branch to take a hand, to see if there is a fresh institution in the roots?

If there is, it proves that there is vitality, and if it is gone, the branches cannot be stopped, it proves that it has long since died. The growth of green seedlings is inseparable from water, especially the tree stems that store a lot of water. When planting a surviving fruit tree, the rhizome has already stabilized its absorption capacity and can continuously absorb nutrients from the soil layer to meet the needs of the tree stem.

The stems are well-watered, the branches are rounded, and the buds look quite delicate. If you gently cut through the roots, you can see the green epidermis. If the fruit tree does not survive, the rhizome cannot absorb nutrients and nutrients.

Under the influence of the external climate, the plants are constantly flowing water, and on the contrary, the tree stem suffers from water shortage. The roots of the tree are generally gradually wrinkled and dark, and the bud points are slowly withering. Eventually, the whole plant will completely wither due to too much water.

After transplantation, observe whether the leaves of the big tree turn green and return to normal; Observe whether the color of the large bark layer changes and whether the water is full; Observe whether the color of the large tree is fresh, whether it is dry and shriveled, or browned and necrotic; Make an observation hole near the soil ball to observe whether the root system is necrotic or has new roots;

It is necessary to pay attention to the growth of the plant, and it is necessary to observe whether the leaves are full, so that you can judge whether it can survive.

Observe the leaves of the tree, if the leaves turn green, then it means that it can survive.

The root regeneration ability of chestnut is poor, and it is difficult to heal after root injury. In order to ensure the survival rate of transplanting large trees, the following points should be paid attention to in the transplanting process: Dig a large pit when raising seedlings, try to hurt the big roots as little as possible, and carry more thin and fibrous roots with mounds.

The planting pit should be large to ensure that the root system of the transplanted tree is fully extended. After planting, it is steady, watered thoroughly, and covered with mulch. Re-prune the aboveground part, and only retain the necessary large branches to reduce the water dispersion loss of the tree; Apply a protective agent to the wound to reduce the risk of infection.

A tripod is built to support the trunk and prevent it from tilting.

1. When seedlings emerge, it is necessary to pay attention to the loss of water from the roots and roots as much as possible, so the transplantation of large trees should bring a large enough soil ball to ensure that the roots and roots are less injured and the roots are less water-loss.

2. Try to shorten the time between seedling raising and planting to reduce water loss.

3. Ensure planting quality standards such as planting depth and timely irrigation.

4. Properly prune or dry to reduce evaporation.

5. Master the best planting time, and it is best to have shade measures for planting trees in hot summer.

Trim the branches first, the soil ball is as large as possible, spray rooting agent at the roots or wrap the trunk with straw rope (straw) before transplanting, and wet enough water at the roots after planting, and then wet according to the weather conditions.

The temperature is low in early spring, the seedlings are in a dormant state, the soil is relatively moist, and the soil temperature gradually rises, which is conducive to early rooting and easy survival.

Measures to protect the root system: 1. The seedlings do not hurt the roots, and they are planted with the seedlings; 2. Wrap the roots with mud on the way to transport the seedlings; 3. Plant immediately after transportation.

Dip the roots of phosphate slurry: 3 kg of superphosphate, 25 kg of loess, and 80 kg of water are stirred into a pulp, and the roots are dipped thoroughly when planting.

Prune broadleaves, branches.

When planting, fill half of the soil first, lift the sapling upward, and stretch the root system. Refill the soil.

After planting, special person will take care of it.

Summary. Hello <>

The factors that affect the survival of tree transplanting are as follows:1Evergreen trees transplanted without soil balls Evergreen trees must be transplanted with soil balls to survive.

2.The soil ball is too small When transplanting seedlings, the soil ball is much smaller than the specification requirements, and the root system is seriously damaged, making it difficult to survive. 3.

Deciduous tree species are not transplanted with soil balls When planting trees during the growing season, deciduous tree species must also be transplanted with soil balls, otherwise they will die. 4.Watering is not thorough, on the surface it looks like the water in the tree hole has been filled, if you do not use an iron shovel to pound it, it is likely to be watered through, the tree will not be soaked in the soil ball Sometimes the water has filled the entire tree hole, but because of the few times of watering or the water loss is too fast, due to the long-term transportation and the inside of the hard and dry soil ball does not eat enough water, the seedlings will slowly si.

Ambush 2The soil ball is too small When transplanting seedlings, the soil ball is much smaller than the specification requirements, and the root system is seriously damaged, making it difficult to survive. 3.

Deciduous tree species are not transplanted with soil balls When planting trees during the growing season, deciduous tree species must also be transplanted with soil balls, otherwise they will die. 4.Watering is not thorough, on the surface it looks like the water in the tree hole has been filled, if you don't use an iron shovel to pound it, it is likely to be watered through, the tree will not be soaked through the soil ball Sometimes the water has filled the entire tree hole, the chain is eliminated but due to the number of watering times is less or the water loss is too fast, due to long-term transportation and the inside of the hard and dry soil ball does not eat enough water, the seedlings will slowly si.

Try to move trees during the dormant season: If there is no special requirement for the construction period, large tree transplanting should be carried out as much as possible during the dormant period of the trees in autumn and spring. During the dormant period, the root system of the tree has a strong tolerance to broken roots, and the tree has less transpiration in the early ascending body, which is conducive to the root and leaf growth after entering the growth period.

Root treatment: transplanting large trees generally requires transplanting with soil balls, the diameter of the soil balls is required to be equivalent to about 10 times the diameter of the trunk. Before the tree enters the soil, the roots should be trimmed, and the broken roots should be cut together with scissors, so as to facilitate the growth of new roots.

Before the big tree enters the hole, the rooting solution and shasa fungus agent should be sprayed on the roots to facilitate the elimination of shasa bacteria and promote the growth of roots. <>

<> seedlings can be determined to survive 30 days after transplanting. After 30 days of transplanting, if the leaves of the sapling turn green, the color of the sapling's cortex does not change much, the moisture is full, and the xylem is fresh, it can be basically determined that it has survived. You can also make an observation hole at the root of the tree to observe the root system, and if there is no necrotic root system and new roots, you can make sure that the sapling has survived.

The transplanted tree usually takes a year to determine its survival, for example, the transplanted tree in the spring can continue to germinate long branches and long leaves in the spring of the second year, which means that it has survived, the reason is that the transplanted plant is easy to cause dehydration and death in high temperature in summer, and then it is easy to die of frost damage at low temperature in winter, and it can germinate in summer and winter to spring of the next year, indicating that it has resumed its growth state, mainly the recovery and growth of the root system can provide a large amount of water evaporation in summer. Absorb sufficient nutrients to resist the harsh winter cold. Often the leaves of the plant are fine after the summer, but in the autumn or winter, there are dead leaves and dead branches, which is the phenomenon of false life, mainly because the root system does not recover to grow or the water in the hole leads to the death of the transplanted tree, for example, the plant at the end of 2016 will not be able to determine its survival until the spring of 2018.

Note: Please forgive me for answering wrong, do not accept the correct answer, thank you.

In the summer, you can see if you survive in a month, and in the winter, you can see if you are surviving.

Here's how: come.

The next morning, he must check himself, look at it, shake it twice, and step on it.

One look: the upper part of the tree to see if the leaves are.

Firm and plump. The lower part of the tree body is to see whether the planting is too deep, whether the covering soil is too thick, whether there is a lack of water or dryness, and whether there is water accumulation in the terrain.

2. Shake: Shake the tree or push the trunk reasonably with your hands to see if the soil ball is tightly absorbed by the soil and whether it is easy to shake.

Three steps: Use the strength of your feet and your whole body to step on the side of the soil ball of the big tree to feel whether the soil is loose, indicating that the soil density is not enough when planting, such as stepping on the soil.

If it is transplanted on the ground, it can basically not be watered after survival, and occasionally watered when the weather is dry for a long time, but fertilization is still done once or twice a year. If you are potted, you have to water it when it is dry, and you can water it thoroughly, and you don't have to water it every day, because it will rot the roots if you have more water.

False life: The tree body relies on its own nourishment and distribution of buds, but there is no sprout of new roots, and after a period of time, the tree body nutrients are exhausted, and the phenomenon of bud withering and death is called "false life" phenomenon. Therefore, it is not possible to judge whether a tree is alive or not by "sprouting".

Suspended animation: The phenomenon of a tree with sufficient nutrients but no buds or roots is called "suspended animation". The phenomenon of suspended animation of the tree, as long as the nutrients and water are replenished in the later stage, and the roots are maintained in good rooting conditions (breathable.

anti-stagnant water). Use standard rooting products, such as: standard 3721 rooting solution.

Bag liquid, etc. To a large extent, it will promote its germination and rooting, and if measures are not taken in time, it may become a real dead tree.
