Description

  The present invention relates to a method for reactivating a tree having a weak tree vigor, such as an old tree.

Trees are grown and activated by sending underground water and nutrients sucked from the roots to leaves through the conduit of the woody part.
However, when the trunk of a tree is corroded or hollowed out, such as an old tree or an old tree, not only water and nutrients are not sucked up due to the decrease in the conduit, but also it is easy to fall down with a strong wind.
Therefore, in the past, trees were supported by multiple support bars to prevent falling trees, or after the corrosion inside the cavity was removed with chemicals, the cavity was filled with a repair agent such as resin or mortar. By doing so, the progress of corrosion and the fall of trees are prevented (for example, refer to Patent Documents 1 and 2).

  However, the conventional method can prevent the fall of trees and the progress of corrosion, but there is a problem that the trees cannot be reactivated.

  The problem to be solved by the present invention is to provide a method for reactivating a tree that can re-activate the tree and prevent fallen trees.

In order to solve the above-mentioned problem, the method for reactivating a tree according to claim 1 comprises:
A first step of cutting a side bud germinated on a branch of an old tree such as a cherry tree with a blade and applying a rooting activator to the cut portion;
A second step of covering the space from the cut portion to the ground with a pipe filled with culture soil having air permeability and water permeability and containing fertilizer and appropriate moisture inside;
At the stage where a plurality of roots have rooted from the cutting part and have grown to a predetermined length, a third step of cutting a part of one side of the pipe in the growing part and cutting a thin root leaving a thick root;
A fourth step of removing the pipe when the remaining thick root grows in the pipe and its tip extends into the ground and completely takes root;
It was set as the characteristic characterized by comprising.

Moreover, the method for reactivating a tree according to claim 2 is the method for reactivating a tree according to claim 1,
The culture soil includes charcoal.

In the method for reactivating a tree according to claim 3, the method for reactivating a tree according to claim 1 or 2,
In the case where corrosion or a hollow portion is generated on the trunk of the tree, removal of the corroded portion or repair work for filling the hollow portion is performed in parallel.

In the method of reactivating a tree according to claim 1, as described above, the side buds that have sprouted on the branches are cut to reach the ground from the cut portion to the ground, and have air permeability and water permeability. By covering with a pipe filled with culture soil containing moderate moisture, the roots rooted from the cut parts of the side buds are grown into the ground while absorbing moisture and nutrients in the culture soil filled in the pipe Therefore, water and nutrients can be sucked up from the new roots that have taken root in the ground and supplied to the leaves.
Therefore, the tree can be reactivated.
Further, when a plurality of roots are grown and grown to a predetermined length, the thin roots are cut out while leaving the thick roots, whereby the growth of the remaining roots can be promoted.
In addition, it is possible to promote reactivation of trees by growing new roots from side buds that have sprouted on multiple branches in the manner described above, and the multiple new roots act as support rods and You can prevent fallen trees.

  In the method for reactivating a tree according to claim 2, as described above, the activation of new roots can be promoted by including charcoal in the culture soil.

  In the tree reactivation method according to claim 3, as described above, when corrosion or a hollow portion is generated in the trunk of the tree, removal of the corroded portion or repair work for filling the hollow portion is performed in parallel. As a result, the progress of corrosion and the like can be stopped.

It is a figure which shows the 1st process of the reactivation method of the tree of Example 1. FIG. It is a figure which shows the 2nd process of the reactivation method of the tree of Example 1. FIG. It is a figure which shows the 3rd process of the reactivation method of the tree of Example 1. FIG. It is a figure which shows the 4th process of the reactivation method of the tree of Example 1. FIG.

  Embodiments of the present invention will be described below with reference to the drawings.

First, the tree reactivation method of the first embodiment will be described with reference to the drawings.
In addition, this Example 1 demonstrates the reactivation method of the old cherry tree in which the conduit | pipe decreased by the hollowing of a wood part progressing, and the suction of water and nutrients became inadequate.

  In Example 1, first, as shown in FIG. 1, the side buds 3 germinated on the branches 2 of the cherry blossoms 1 are cut off with a sharp blade and the rooting activator (trade name: Menedale, etc.) with a brush at the cutting part 4. Is applied (first step).

Next, as shown in FIG. 2, the pipe 5 filled with the culture soil F having air permeability and water permeability and containing fertilizer, appropriate moisture and charcoal is formed between the cut portion and the ground G. Cover (second step).
In Example 1, air permeability and water permeability are ensured by making a large number of holes 51 in the outer peripheral surface of the resin pipe.
Further, the lower end of the pipe 5 is closed with a cement or the like so that no gap is formed between the upper end opening edge of the pipe 5 and the branch 2, and the lower end of the pipe 5 is predetermined so that no gap is formed between the lower end of the pipe 5 and the ground G. It is desirable to embed it in the long ground.

  Next, when a predetermined year has passed since the work was started, a plurality of roots from the cutting part 4 are rooted and grown to a predetermined length. Cut the thin roots leaving the roots 6 (third step). Thereafter, as the thick root 6 grows in the pipe, one side portion of the pipe 5 is gradually cut from above.

  Next, after a predetermined period of time has elapsed since the work was started, the pipe 5 is removed when the remaining thick root 6 grows in the pipe 5 and its tip extends into the ground and completely takes root (fourth step). ).

  In addition, when corrosion and the cavity part have generate | occur | produced in the trunk 7 of the cherry blossom 1, the repair work which removes a corrosion part and fills a cavity part with resin or mortar 8 is performed in parallel.

Next, the effect of the first embodiment will be described.
In the method for reactivating the tree of Example 1, as described above, the side buds 3 germinated on the branches 2 are cut and from the cut portion to the ground G have air permeability and water permeability. By covering the inside with a pipe 5 filled with fertilizer and culture soil F containing appropriate moisture, the roots rooted from the cut parts of the side buds 3 are filled with moisture and nutrients in the culture soil F filled in the pipe 5. Because it can grow up to the ground while absorbing, it can absorb water and nutrients from new roots that have taken root in the ground and supply them to the leaves.
Therefore, the tree can be reactivated.

  Further, when a plurality of roots are grown and grown to a predetermined length, the thin roots are cut out while leaving the thick roots 6 so that the growth of the remaining roots can be promoted.

  In addition, it is possible to promote reactivation of trees by growing new roots from the side buds 3 germinated on the plurality of branches 2 as described above, and the plurality of new roots serve as support rods. It will be possible to prevent the fall of trees.

  Moreover, by including charcoal in the culture soil F, activation of new roots can be promoted.

  In addition, when corrosion or a hollow portion is generated in the trunk 7 of the tree, the progress of the corrosion or the like can be stopped by performing the repair work for removing the corroded portion and filling the hollow portion in parallel. Become.

  Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.
