Problems with transplanting trees in summer, is it okay to transplant seedlings in summer?

In the summer, we transplant the trees that have been planted and live and the large trees that have been planted for many years to other places, and in order to increase the survival rate, we can take some special measures in addition to the conventional methods.

1. The size of the soil ball is determined according to the size of the DBH The diameter of the soil ball of the transplanted tree with a DBH of less than 10 cm (including 10 cm) is not less than 40 cm, and the height of the soil ball is not less than 40 cm; If the diameter at breast height is 11-15 cm, the diameter of the soil ball is generally not less than 80 cm, and the height of the soil ball should reach 40-60 cm; If the diameter at breast height is more than 15 cm, the diameter and height of the soil ball should be determined according to the need.

2. Proper thinning of branches The amount of thinning should be determined according to the tree species and the weather conditions at that time. In dry weather, it is appropriate to be more sparse, and vice versa, but it is generally required to be thinned by 30%-40%. Whether it is the main branch or the branch, the top of the branch should be cut off by 30-40 cm.

For example, for camphor trees, all leaves should be removed.

3. Protect the trunk The trunk should generally be wrapped from the ground to the first branch with a straw rope. The whole process of lifting and transportation should be done as far as possible without hurting the trunk and branches. If you accidentally touch (crush) the trunk of the tree, dig up all the loose bark of the injured area, and immediately apply petroleum jelly, or you can use potassium permanganate solution to rinse it off, and then wrap (wrap) it well.

4. The transplantation pit should be wide, deep and large Generally, the length, width and depth of the transplantation pit are all meters. Large trees should also be appropriately enlarged, and small trees (DBH below 10 cm) should not be reduced. The pit is first filled to about 70% with 2 kg of phosphorus-based compound fertilizer, and then filled to the level of the ground.

5. Transplanting details When planting, first water along the edge of the tree pit, and in the dry season, it must be watered thoroughly to make the pit wall fully absorb. If it rains heavily, you can skip watering. Once the water stain has dried a bit, dig a small pit in the center of the transplant pit.

The size and depth are basically the same as the height and height of the soil ball of the transplanted tree. Then place the tree gently in a small pit, erect it well, and then fill it with soil. The soil in the pit should not be too much at a time, and it should be filled layer by layer and stepped on layer by layer, so that the soil ball in the pit can be squeezed tightly until it is level with the ground.

The top of the ball should also be almost level with the ground. Then enclose a cofferdam slightly larger than the soil ball along the tree, the weir is about 10 cm high, and then water.

6. Watering after planting Watering for the first time, and then water the entire transplanting pit thoroughly, but the watering speed should be slow. The cofferdam can be filled with water each time, and then filled with the cofferdam after all the water seeps in, and so on several times.

After transplanting, water the second time the next day, the third time on the fifth day, the fourth water every 3 days, and the fifth water every 7 days or so. The cofferdam is slowly filled with each watering. If there are several heavy rains after planting, the number of watering times and the amount of each time should be decided according to the actual situation.

It should be noted that the number of watering should be decided according to the actual situation, and the number of days between should also be determined according to the actual needs. The amount should not be too much or too little at a time, otherwise it will cause "soaking roots" or "drought" the roots to death, which will affect the survival of the transplanted tree. After the fifth watering, the management of the transplanted trees is basically the same as that of spring seedlings.

What season is the right time to transplant trees? Deciduous trees are planted in deciduous leaves, and the transplanting time must be right!

Picking trees in summer can survive, but the survival rate is low, which is due to the high temperature causing a large amount of transpiration of branches and leaves, which affects the survival of trees. Therefore, in order to improve the survival rate of summer seedling planting, some necessary measures need to be taken, as follows:

First, the choice of planting seedlings

Because summer is not the planting season, the temperature is high, the evaporation is large, it is easy to cause plant dehydration, the requirements for planting plants themselves are higher, in the selection of materials to choose as far as possible to develop the root system, grow strong, no pests and diseases of the seedlings.

In the case that the specifications and forms meet the design requirements, the following principles should be followed:The first is to try to use small seedlings, small seedlings have stronger root generation than large seedlings, and the survival rate of transplanting is higher. Second, it is best to use seedlings with false planting, and seedlings with short planting time have more vigorous root activities; If there is no false planting seedling, the seedlings that have been transplanted in the past 2 years should be selected, such seedlings have many fibrous roots, the soil ball is not easy to break, the water absorption capacity is strong, and the survival rate of seedlings is higher.

In addition, it should be noted that large seedlings should be cut off and transplanted in advance.

2. Treatment and digging of planting soil

The summer planting soil must ensure sufficient thickness to ensure that the soil is fertile and loose, with good air permeability and drainage performance. For plots with harmful substances such as construction waste, the waste soil should be removed, replaced with good soil suitable for plant growth, and well-rotted organic fertilizer should be applied as base fertilizer. When planting seedlings in the summer, the size of the planting hole must meet the standard requirements.

3. Seedling raising and transportation

Seedling raising and transportation are the key links to ensure the survival of planting, and the control of soil ball quality and intermediate transportation speed is very important. The seedlings should pay attention to weather changes, generally choose to raise seedlings on cloudy days, transport to the site overnight, and ensure that the seedlings are fresh and the soil balls are intact and dense. When seedlings emerge, increase the size of soil balls to improve the survival rate.

Empty acres are recommended:The diameter of the soil ball is generally times that of normal season transplanting. The larger the soil ball, the more complete the root system is, and the easier it is to survive the planting.

Seedling transplantation should avoid hot and dry weather as much as possible, and seedling emergence should be arranged after 4 o'clock in the morning or afternoon to reduce the loss of seedling moisture. Anti-transpiration agent can be sprayed on the crown before seedling, and transported immediately after seedling. If the soil is loose and not easy to form balls, the roots can be dipped in mud immediately after seedlings rise to keep the root system moist.

Finally, when planting, rooting powder and a certain amount of phosphorus-based compound fertilizer can be put into the hole of large flowers and shrubs, and the soil can be filled to about 70%, and then filled to the level of the ground; And build a high l0 375px irrigation shed to lose water and soil, and water it can be watered thoroughly.

First, the selection of tree species in winter is generally dormant period, just suitable for transplanting, but also to distinguish different tree species, not all tree species are suitable, such as cedar, black pine, oriental cypress and other species of survival rate is relatively low, you can choose acacia, sycamore, privet and other types. It should also be noted that the selected seedlings must grow vigorously and have a relatively developed root system.

Second, dig out the tree body before digging can be watered appropriately to soften the soil next to the root system, and then dig out the tree, pay attention to protect the root system, prevent damage to the root system, and protect the crown in the process.

3. Prune trees need to be pruned before transplanting, the branches above are thinned and truncated, and the root system under the trunk should be pruned after digging out, and some rotten roots should be removed, and fungicides should be sprayed on the top to prevent infection at the wound, which can improve the probability of survival.

Fourth, the transplantation digs a deep pit as a place for transplantation and burial, pay attention to the diameter and depth should be greater than the soil ball, and then bury, and then pay attention to anti-freezing.

The success rate of transplanting trees in summer is not high, because the scattered ridge is too strong for the transpiration of trees in summer, and the plant is often in the growth period, at this time transplanting will have a certain impact on its root system, so the success rate of summer transplantation is not high, and it should be specially cared for and treated when transplanting in summer to increase the probability of success.

We all know that the success rate of transplanting trees is higher in spring and autumn, and the success rate of transplanting in summer will not be too high, because the temperature in summer is higher, and summer is the growth period of many plants, and transplanting will bring damage to its root system at this time.

1. Prune branches

If you want to transplant trees in summer with a higher success rate, you must reduce its transpiration, so you must increase the dredging and pruning of its branches, branches and leaves, so as to reduce its evaporation, and if necessary, you can cut it off, so that this operation can ensure that the transplanted trees in summer have a certain probability of survival and infiltration.

2. Root treatment

When transplanting, we must ensure the integrity of the root system of the plant, you can bring some original soil, you can spray some water on its root system, to ensure that the root system moisture is sufficient during the transplantation, so that there is hope of survival after the tree is transplanted, if the root system of the tree is damaged, the success rate of the entire transplanting will be greatly reduced.

3. Transplantation process

In the summer, the whole transplanting process should take special care of the tree, because a little carelessness will reduce the chance of success, transplantation should try to shade it, you can spray some anti-transpiration agents to prevent water loss, to keep the tree soil moist at all times, so that the tree can be transplanted well in the summer.
