Description

TECHNICAL FIELD The present invention relates to a tree-taking tool and a tree-taking method used in a tree-taking method, which is one of tree breeding methods.

The harvesting method is a relatively reliable rooting method for trees, and can be applied even to varieties in which cutting and grafting are difficult. Among them, the aerial harvesting tree method (high harvesting method) is widely used in the fields of hobbies such as forestry and personal bonsai because it is possible to select a branch with a desired thickness and shape.

In the high-take method, the branches near the part to be rooted are peeled off in a ring shape, covered with sphagnum moss or the like moistened with water as a rooting filler, and covered with a thin vinyl sheet or the like. The method is taken. After several months, it is confirmed that the roots have been sufficiently rooted from the peeled site, and branches are cut at the lower part of the peeled site to obtain a tree.

In the conventional method generally used, it took about 5 minutes to perform a series of tree-cutting processes from peeling a branch into a ring, covering it with a vinyl sheet and fixing it with a string or tape. .. Due to the rooting rate, the tree-cutting process is usually performed within a limited period of one year, and it is troublesome in the prior art to carry out tens or hundreds of tree-cutting processes at one time. There was a problem that it took too long. This problem is solved by the one-touch harvesting tool which is the invention described in Patent Document 1. According to FIG. 2 and the like of Patent Document 1 and the detailed description of the device, a tool combining two recessed containers having upper and lower recesses for sandwiching branches and a plurality of holes for passing air or water is used, By filling the inside with sphagnum moss and soil, which is a filling material for rooting, it is possible to attach the tool to the branch that has been peeled off with a single touch, so that it is possible to easily process the harvested tree.

However, in the invention of Patent Document 1, there is a problem that the sphagnum moss and the like filled inside is excessively dried because the small holes for ventilation and water passage are formed on the entire wall surface of the cutting tool. If the sphagnum moss, which is a filling material for rooting, is too dry, it affects the rooting of plants. In order to prevent sphagnum moss and the like from becoming too dry, it is necessary to periodically visually check the water content of sphagnum moss and the like, and water it if necessary. There was a problem that the grower's monitoring burden and labor were too much.

In Patent Document 1, as shown in FIG. 3, FIG. 4, etc., in order to prevent sphagnum moss, etc., which is a filling material for rooting, from drying out, a large amount of rainwater is taken into the cavity of the tree tool. There are some structural improvements, and a tank for storing the captured rainwater is installed on the outer wall of the harvesting tool. However, even if the structure of the tree harvesting tool is devised, since there is a hole in the wall surface, evaporation of water cannot be suppressed, and if a rainwater storage tank is provided on the outer wall of the tree harvesting tool, the weight increases when water accumulates, It was inevitable that the branches would be overloaded.

Further, the following first to sixth embodiments and their modified examples, examples, and reference examples exemplify devices and methods for embodying the technical idea of the present invention. The technical idea does not specify the materials, shapes, structures, arrangements, etc. of the components as follows. The technical idea of the present invention is not limited to the contents described in the first to sixth embodiments and the modifications, examples, and reference examples thereof, and the technical scope defined by the claims described in the claims. Various changes can be made within the range.

(First embodiment)
As shown in FIGS. 1( a) and 1 (b ), a harvesting tool 11 according to a first embodiment of the present invention has a first closed cover portion 21 and a three-dimensional mirror image of the first closed cover portion 21. A second closed cover portion 23 having a shape, and a connecting portion 41 for connecting the connection-side end portion of the first closed cover portion 21 and the connection-side end portion of the second closed cover portion 23 in a rotationally movable manner. The first closed cover part 21 includes a first top plate having a semicircular outer peripheral side, a first bottom plate facing the first top plate and having a semicircular outer peripheral side, and a first top plate and a first bottom plate. It is a gutter-shaped shape that connects the first top plate and the first bottom plate so as to provide the first cavity therebetween, and has the arc-shaped first side wall plate along the semicircular outer periphery. The "connection-side end" is one end along the longitudinal direction of the gutter, and the end opposite to the connection-side end is defined as the "open/close-side end". A contact end is provided on a chord (diameter) part of the semicircle of the first top plate, and a contact end is provided on a chord part of the semicircle of the first bottom plate. The second closed cover portion 23 has a semicircular outer peripheral side and a second top plate having a contact end portion capable of linearly contacting the first top plate, and a semicircular outer peripheral side having a first bottom plate and a line. A second bottom plate having a contact end capable of contacting with each other in a circular shape, and a second side wall plate having an arc shape along the semicircular outer circumference, which connects the second top plate and the second bottom plate. A contact end is provided on the part of the chord of the second top plate with respect to the arc of the semicircle, and a contact end is provided on the part of the chord of the second bottom plate with respect to the arc of the semicircle. “Line-shaped contact” has a macroscopic meaning, and in reality, each contact end has a thickness (line thickness), so the contact end of the second top plate and the first top plate It goes without saying that the contact ends of the two come into planar contact with each other. Similarly, due to the thickness of the line, the contact end of the second bottom plate and the contact end of the first bottom plate are in planar contact with each other. The second side wall plate of the second closed cover portion 23 has a curved surface that can form a uniform continuous surface with the outer peripheral surface of the first side wall plate of the first closed cover portion 21. Since the second closed cover portion 23 also has a gutter-like shape, the second top plate and the second bottom plate are provided between the second top plate and the second bottom plate so as to provide the second cavity that can be connected to the first cavity. Are connected. The contact end of the first top plate that contacts the contact end of the second top plate is in contact with the contact end of the second top plate so that the contact end of the second top plate can linearly contact the first top plate. It has a position, shape, and thickness that are in a mirror image relationship with the contact end.

Similarly, the contact end of the first bottom plate that contacts the contact end of the second bottom plate is the contact end of the second bottom plate so that the contact end of the second bottom plate can make linear contact with the first bottom plate. It has a position, a shape, and a thickness in a mirror image relationship with the part. The first top plate of the first closed cover portion 21 is provided with a semicircular first notch 43a, and the first bottom plate is provided with a semicircular second notch 45a. The second ceiling plate of the second closed cover portion 23 is provided with a semicircular third notch 43b, and the second bottom plate is provided with a semicircular fourth notch 45b. The woodcutting tool 11 according to the first embodiment is configured such that one of the first closed cover portion 21 and the second closed cover portion 23 is rotationally moved about the coupling portion 41 as an axis, so that FIG. The "closed state" shown in Fig. 1 and the "open state" shown in Fig. 1B can be arbitrarily set.

The “closed state” is a state in which the first side wall plate of the first closed cover portion 21 and the second side wall plate of the second closed cover portion 23 circulate as a uniform continuous surface. In the "closed state", the first top plate of the first closed cover part 21 and the second top plate of the second closed cover part 23 are connected at the same horizontal level to form the upper end surface of the cylinder. .. Further, the first bottom plate of the first closed cover portion 21 and the second bottom plate of the second closed cover portion 23 are joined at the same horizontal level to form the lower end surface of the cylinder. In the "closed state", as shown in FIG. 1(a), the circumferential surfaces of the first closed cover portion 21 and the second closed cover portion 23, which form the side wall surface, have a continuous cylindrical shape, Since the top hole 43 is opened on the end face and the bottom hole 45 is opened on the lower end face of the cylinder, the structure is close to a closed state, but strictly speaking, it is an open state. On the other hand, as shown in FIG. 1B, in the "open state", the first side wall plate of the first closed cover portion 21 and the second side wall plate of the second closed cover portion 23 are connected only by the connecting portion 41. The patient is in an open state. By changing from the open state to the closed state, the tree-cutting tool 11 according to the first embodiment can store the branches of the tree-cutting target via the top hole 43 and the bottom hole 45 as shown in FIG. 3. ..

In the tree-cutting tool 11 according to the first embodiment, the branches of the tree-cutting target are cavities formed by the first closed cover portion 21 and the second closed cover portion 23 through the top hole 43 and the bottom hole 45. By being accommodated, part of the top hole 43 and the bottom hole 45 is closed, and a closed state is achieved in which the level of sealing is increased. The diameter of the top hole 43 and the diameter of the bottom hole 45 are each set in a plurality of stages so as to increase the degree of freedom in selecting the diameters of the top hole 43 and the bottom hole 45 and facilitate an appropriate level of sealing. However, it is preferable to prepare a set of a plurality of harvesting tools 11. By appropriately selecting the diameter of the top hole 43 and the diameter of the bottom hole 45 that are suitable for the thickness of the target branch of the tree-cutting target from the set of the plurality of tree-cutting tools 11, the branch of the tree-cutting target is selected. It is possible to properly adjust the clearance between the top hole 43 and the bottom hole 45. Further, it is not necessary to select the same diameter for the top hole 43 and the bottom hole 45, and the diameter of the top hole 43 is set to be larger than that of the bottom hole 45 in consideration of the change in the thickness of the branches during the harvesting period. , May be made very small. On the contrary, in order to prevent the cutting tool 11 from slipping off the tree, the diameter of the top hole 43 is made larger than the diameter of the bottom hole 45, and the gap between the diameter of the bottom hole 45 and the branch is 0.5 to. It is also effective to set it as small as about 2 mm. Even if the diameter of the top hole 43 is made smaller than the diameter of the bottom hole 45, and the gap between the diameter of the top hole 43 and the branch is made as small as about 0.5 to 2 mm, the cutting tool 11 does not slip off the tree. It can be prevented.

As shown in FIG. 1(b), the first closed cover portion 21 and the second closed cover portion 23 are cylindrical (cylindrical) having a hollow portion, and are cut surfaces including the center line in the longitudinal direction of the cylindrical, The shape is such that it is split in half in parallel to the length direction, and semicircular cutouts are provided on the top and bottom surfaces, respectively. The "first side wall plate" is defined as a plate-shaped portion that connects the first top plate and the first bottom plate in the outer shape of the divided three-dimensional first closed cover part. The same applies to the "second side wall plate", which is defined as a plate-shaped portion that connects the second top plate and the second bottom plate in the outer shape of the split three-dimensional second closed cover portion.

As shown in FIG. 1B, the first hermetically-sealed cover portion 21 has a semicircular-shaped first notch 43a in a part of an upper portion which is a semicircular-shaped upper surface, and the second hermetically-sealed cover portion 21. 23 has a semicircular third notch 43b in a part of the upper portion which is the semicircular upper surface. When the overall form of the tree-taking tool 11 changes from the open state as shown in FIG. 1( b) to the closed state as shown in FIG. The top hole 43 formed by the notch 43a and the third notch 43b appears. When the thickness of the branch to be cut is 1 cm, the diameter of the top hole 43 is preferably 1.05 to 2.0 cm, and more preferably 1.05 to 1.5 cm. More preferably, it is 1.05 to 1.2 cm from the viewpoint of preventing nesting of ants. From the relationship with the rooting rate, a young branch of the first or second year is often selected as a branch used in the tree-taking method, and the diameter of the top hole 43 was calculated in consideration of the thickness of the branch. If the difference between the diameter of the hole 43 and the diameter of the branch is too small, the degree to which the cutting tool 11 is fixed to the branch increases, but it may cause damage to the branch due to contact with the edge of the hole 43, and rainwater It will also flow into the cutting tool 11 and prevent fresh air from passing through. On the other hand, if the difference between the diameter of the top hole 43 and the outer diameter of the branch is too large, the cutting tool 11 may slip off the branch. As a result of the experiment, it was found that it is more preferable as the diameter of the top hole 43 that the gap between the branch and the hole is about 0.5 to 2 mm.

The same applies to the bottom hole 45, and as shown in FIG. 1B, the first closed cover portion 21 has a semicircular second cutout 45a in a part of the lower portion which is a semicircular bottom surface. However, the second closed cover portion 23 has a semicircular fourth notch 45b in a part of the lower portion which is a semicircular bottom surface, and is changed to a closed state as shown in FIG. 1(a). When the overall shape of the cutting tool 11 changes, a bottom hole 45 formed by the second cutout 45a and the fourth cutout 45b appears in the lower portion of the cutting tool 11. When the thickness of the branch to be cut is 1 cm, the diameter of the bottom hole 45 is preferably 1.05 to 2.0 cm, more preferably 1.05 to 1.5 cm. More preferably, it is 1.05 to 1.2 cm from the viewpoint of preventing nesting of ants. From the relationship with the rooting rate, a young branch of the first or second year is often selected as a branch used in the tree-taking method, and the diameter of the bottom hole 45 was calculated in consideration of the thickness of the branch. If the difference between the diameter of the bottom hole 45 and the diameter of the branch is too small, the degree to which the cutting tool 11 is fixed to the branch increases, but it may cause damage to the branch due to contact with the edge of the bottom hole 45, and rainwater It also prevents the removal of the unnecessary water from the inside of the cutting tool 11. It also leads to obstruction of sufficient ventilation. On the other hand, if the difference between the diameter of the bottom hole 45 and the diameter of the branch is too large, the cutting tool 11 is likely to slide off the branch. As a result of the experiment, it was found that it is more preferable for the diameter of the bottom hole 45 that the gap between the branch and the hole is about 0.5 to 2 mm.

In order to prevent the cutting tool 11 from slipping off the branch, the diameter of the bottom hole 45 is set to a small difference of 0.5 to 1.0 mm from the thickness of the branch, and the diameter of the top hole 43 and the diameter of the branch are set. And the diameter of the bottom hole 45 may be smaller than the diameter of the top hole 43. The open degree of the cutting tool 11 in the open state can be arbitrarily adjusted, and is not limited to the open degree shown in FIG.

The first closed cover portion 21 and the second closed cover portion 23 are connected by a connecting portion 41. The first closed cover part 21 and the second closed cover part 23 only need to be connected, and are connected from the stage of forming the first closed cover part 21 and the second closed cover part 23. Alternatively, the first closed cover portion 21 and the second closed cover portion 23 may be separately molded and then joined using some kind of joint or the like.

As shown in FIG. 1(a), a frame-shaped first fixing means 31 is provided on a part of the outer wall surface of the opening/closing side end of the first side wall plate of the first hermetically-sealed cover portion 21, and the second hermetically-sealed portion A rod-shaped second fixing means 33 is provided on a part of the outer wall surface of the opening/closing side end of the second side wall plate of the cover portion 23. The outer dimension of the rod-shaped portion of the second fixing means 33 is matched with the inner diameter dimension of the frame of the first fixing means 31 with a clearance of 10 to 100 microns. When the cutting tool 11 is in the closed state as shown in FIG. 1( b ), the frame of the first fixing means 31 is fitted so as to be caught by the rod-shaped portion of the second fixing means 33, and the first sealing cover portion 21 and Since the second closed cover part 23 is fixed, the closed state can be maintained with one touch, and the open state can be returned with one touch. The switching fastener for fixing the first closed cover portion 21 and the second closed cover portion 23 is not limited to the fitting structure like the first fixing means 31 and the second fixing means 33. If the first closed cover portion 21 and the second closed cover portion 23 can be opened and closed with one touch and fixed to switch the restraint in the open/closed state, a hook structure or a snap button structure for hooking one on the other A metal buckle structure, a binding belt structure, a surface fastener structure, or the like may be used. Further, as long as the first closed cover portion 21 and the second closed cover portion 23 can switch the open/closed state with a single touch, a structure in which a magnetic force is used to fasten them may be used.

The shape of the cutting tool 11 shown in FIGS. 1(a) and 1(b) is a column, but may be spherical or any other shape. Considering planting in soil after the harvesting is completed and the root extending obliquely downward, a columnar shape or a spherical shape is preferable in terms of handleability. When a columnar shape is adopted as shown in FIGS. 1A and 1B, it is desirable that the diameter is 3.0 to 5.0 cm and the length is 7.0 to 9.0 cm. More preferably, the diameter is 3.5 to 4.5 cm and the length is 7.5 to 8.5 cm. As a result of comprehensively considering the ease of rooting, the amount of filling material for rooting, the burden on the branches due to weight, and the sufficient coverage of the peeled parts of the branches, etc., the value calculated by the inventors through repeated experiments is there.

As the material of the first closed cover portion 21 and the second closed cover portion 23, any material such as plastic, thin metal, wood, etc. can be used. However, considering the weight and the influence on the plant, metal is not preferable. Further, in order to withstand repeated use, a lightweight plastic, for example, a plastic mainly made of polyvinyl chloride is preferable. In particular, polyvinyl chloride is suitable because it is a relatively soft material and does not easily damage the epidermis of the branch when it comes into contact with the branch. When polyvinyl chloride is used as a raw material, a plasticizer which is usually used may be added. Examples of the plasticizer include many types such as phthalic acid type, adipic acid type, phosphoric acid type, trimellitic acid type, and a plurality of plasticizers may be added. As a result of the inventor's experiment, when silicon resin was used as the material of the first closed cover portion 21 and the second closed cover portion 23, it was not suitable because it was not possible to hold the moistened rooting filler.

Further, regarding the color, a darker color is preferable in relation to the rooting rate. It is more preferably black. From the viewpoint of rooting rate, it is preferable to avoid transparent or translucent regardless of color. It is preferable that the material is light in color and has low light transmittance even if it is white, for example. In addition, it is known that birds and beasts mistake fruits such as red and pink for bright colors even if they are dark colors.In fact, in the experiment of the inventor, it was confirmed that the birds pecked with their beaks. Black, brown, gray and the like are more preferable because there is a risk that the wood tool will be in an open state.

(How to use the cutting tool according to the first embodiment)
A method of using the harvesting tool according to the first embodiment will be described below with reference to FIGS. 2 and 3. As shown in FIG. 2, the cutting tool according to the first embodiment is opened, and the insides of the first closed cover portion 21 and the second closed cover portion 23 are filled with sphagnum moistened with water. The sphagnum moss is sufficiently filled so that a gap with the branch does not occur in the hollow portion in order to prevent it from slipping down from the branch when it is used in a closed state where the circumferential surface is continuous. In FIG. 2, sphagnum moss was given as an example of the rooting filler, but the present invention is not limited to this, and other moisture retaining agents, moisture retaining soil or the like may be used. When carrying, it is in a closed state as shown in FIG.

The state in which the tree-cutting tool 11 according to the first embodiment is actually attached to the tree-cut target branch is as shown in FIG. 3. A part of a desired length from the end of the branch, that is, a part to be rooted, is peeled in an annular shape with a width of about 2 cm, and the whole peeled part 73, the trunk side 71a of the branch and the end side 71b of the branch. The cutting tool 11 according to the first embodiment, which has been filled with a rooting filler such as sphagnum moss in advance so as to include each several cm, is closed to complete the installation. The top hole 43 accommodates the branch end side 71b and the bottom hole 45 accommodates the branch trunk side 71a, respectively, and the hollow portion formed by the first closed cover portion 21 and the second closed cover portion 23 is in a closed state. The level of. The filling material for rooting that has been filled is sufficiently filled so as to protrude from the first cavity and the second cavity when the cutting tool 11 is in the open state, and the cutting tool 11 is closed. In doing so, the rooting filler is compressed and pushed into the hollow portion of the cutting tool 11. A force (pressure) for returning to the original shape acts from the compressed rooting material. When the cutting tool 11 is closed with a branch, the pressure causes the branch to be caught. Therefore, even if the top hole 43 and the bottom hole 45 are not in contact with the branch, The tool 11 will be held.

By using the wood removal tool 11 according to the first embodiment, it is possible for a person who does not have any special technique to perform the process from the annular peeling to the installation of the wood removal tool 11 in about 30 seconds to 1 minute. In the tree-cutting process using the tree-cutting tool 11 according to the first embodiment, it is sufficient to bring only the tree-cutting tool 11 filled with the rooting filler and the peeling tool, and the work can be performed smoothly.

As a result of the experiment, it was found that the method of using the harvesting tool according to the first embodiment can be applied to various trees. We have succeeded in obtaining a tree with a constant rooting rate for cypress trees such as Aomori Hiba, cherry trees such as double cherry blossoms and weeping cherry trees, and other trees such as yew, Japanese maple, and wig. Of these, "Yaezakura" is a general term for cherry blossoms that give flowers to Yaezaki, and is also known as "Kikuzakura." Examples of varieties include Kanzan (Kanyama), Ichiyo (one leaf), Fugenzo (Fugenzo), Yaebeshidare (Yaeko weeping), and the like. According to the tree-cutting method using the tree-cutting tool according to the first embodiment, it is possible to obtain a tree-cut with a constant rooting rate even for a double cherry tree that is not suitable for the tree-cut.

According to the tree harvesting tool according to the first embodiment, sphagnum moss and the like can be obtained without artificially replenishing water into the sphagnum moss and the like filling the cavity during several months (tree harvesting period) when sufficient rooting is confirmed. Are rarely too dry. From the amount of sphagnum required for rooting, the thickness of the branches, etc., appropriate values for the dimensions of the harvesting tool and the diameters of the top hole and bottom hole for taking in rainwater are calculated, and then according to the first embodiment. This is because the harvesting tools are designed.

In addition, in the cutting tool described in the invention of Patent Document 1, a large number of small holes for ventilation and water passage are provided. In the woodcutting tool according to the first embodiment, since the first airtight cover portion 21 and the second airtight cover portion 23 having high airtightness are used, small holes for ventilation and water passage are unnecessary, and The cost and labor can be greatly reduced. Further, in the tree-cutting tool described in the invention of Patent Document 1, rainwater storage tanks are separately provided because water diffuses from the small holes for ventilation and water passage. In the tree-cutting tool according to the first embodiment, the first airtight cover portion 21 and the second air-tight cover portion 23 having high airtightness are used, so that it is easy to maintain the water content necessary for the tree cut and the rainwater storage tank. Since it is not necessary to attach additional devices such as, the structure is simplified and the manufacturing cost and labor can be greatly reduced.

Furthermore, since the tree-cutting tool according to the first embodiment can be arbitrarily changed to the open state or the closed state with one touch, the rooting state can be easily confirmed from the initial stage of the tree-cutting period. The name of the device of Patent Document 1 is "one-touch cutting tool", but in the device described in Patent Document 1, there is a time-consuming procedure such as tying "one-touch cutting tool" with a string, a liner, or a vinyl tie. It is necessary, and in reality, it is not possible to realize the open or closed state with one touch. Especially when tied with a string or the like, it is necessary to replace the string or the like, and observing the rooting state many times is a laborious task. In addition, with the conventional technique of cutting trees with thin vinyl sheets, etc., it is often the case that the upper and lower ends of the vinyl sheets are tied up with a string or tape, so it is not possible to open them in the middle to check the rooting condition. It is usually not done. Since the tree-cutting tool according to the first embodiment constitutes a switching fastener that can be operated with one touch by the first fixing means and the second fixing means, the opening/closing state can be switched in a short time as necessary. It is possible. For this reason, when the cutting tool according to the first embodiment is used, it is possible to switch the open/closed state with one touch as many times as possible and observe the rooting state, and it is easy to check the success or failure of rooting from the initial stage at any time. Yes, you can efficiently make a tree.

Furthermore, the tree-cutting tool according to the first embodiment is resistant to wind and rain and damage to birds and animals. The conventional technique of applying a vinyl sheet or the like has a problem that the vinyl sheet is exposed to wind and rain and is torn, or birds and beasts are damaged by crows and the like. With the use of the harvesting tool according to the first embodiment, since these problems hardly occur, it is possible to obtain a harvesting tree stably and efficiently.

Furthermore, in the tree-cutting tool according to the first embodiment, since appropriate numerical values for the diameters of the top hole and the bottom hole are calculated, it is difficult for ants to nest in sphagnum moss or the like, which is a filling material for rooting. In particular, if the gap between the branch and the top hole or bottom hole is about 0.5 to 2 mm, it is more difficult for ants to nest. When an ant nests in sphagnum moss, a gap is left between the ring peeling site and sphagnum moss, and water supply to the ring peeling site is interrupted, leading to a decrease in rooting rate. When the cutting tool according to the first embodiment is used, invasion of ants from the top hole or the bottom hole can be suppressed, and thus a gap between the annular peeling site and sphagnum moss is unlikely to occur.

(The tree-taking method according to the first embodiment)
The tree-cutting method according to the first embodiment uses a tree-cutting tool 11 according to the first embodiment as shown in FIG. 1 as a tree-cutting tool, and rice straw as an example of a rooting filler. In the tree harvesting method according to the first embodiment, (a) a step of immersing rice straw, which is a filling material for rooting, in water, and (b) a filling material for rooting in the first and second cavities. The process of filling rice straw is included. Further, as shown in FIG. 1, (c) the inner diameter of the top hole 43 composed of the first notch 43a and the third notch 43b, and the second notch 45a and the fourth notch 45b. The method includes a step of selecting a branch to be subjected to the tree-cutting treatment, the branch having an outer diameter smaller than the inner diameter of the bottom hole 45 to be formed, and peeling the rooted portion of the branch in an annular shape to form an annular peeled portion. Further, (d) the cutting tool 11 is rotationally moved by rotating one of the first closed cover portion 21 and the second closed cover portion 23 with the joint portion 41 as a rotation axis, and the first closed cover portion 21. An annular peeling part is inserted between the second closed cover part 23 and the second closed cover part 23, and the first closed cover part 21 and the second closed cover part 23 are fixed to the branch by the pressure of the rice straw which is a filling material for rooting. And the step of performing. Further, in the tree-cutting method according to the first embodiment, even after the branches are covered with the tree-cutting tool 11, the open state and the closed state are arbitrarily switched to visually confirm whether or not the annular peeling site is rooted. can do.

Although the straw used in the tree-cutting method according to the first embodiment is rice straw, any rice, wheat, or the like, whose stem is mainly dried, may be used. In the tree harvesting method according to the first embodiment, rice straw is first cut into a length of 1 to 5 cm. From the viewpoint of not inhibiting the growth of roots and the ease of handling the rice straw itself, about 1.5 to 3 cm is more preferable. Next, the cut rice straw is immersed in water for about 5 to 10 minutes. The dipping method may be either a method of pouring water on the cut rice straws, a method of submerging the rice straws in water, or any other method. At this time, an auxin-based growth-promoting hormone agent, a drug containing divalent iron ion as an active ingredient, or the like may be administered to the immersion water.

In the tree-cutting method according to the first embodiment, a portion of a desired length from the end of a branch to be tree-cut, that is, a rooting portion, is peeled in an annular shape with a width of about 2 cm to form an annular peeling portion. .. Next, cover the whole tree peeling site, the trunk side of the branch and the end side of the branch by several cm each, and cover the harvesting tool 11 that has been previously filled with rice straw in a closed state to complete the installation. Is. Explaining with FIG. 3, the harvesting tool 11 in a closed state filled with rice straw covers the entire annular peeling site 73, the trunk side 71a of the branch and the terminal side 71b of the branch by several cm each. The top hole 43 accommodates the end side 71b of the branch, and the bottom hole 45 accommodates the trunk side 71a of the branch. The rice straws are sufficiently filled so as to protrude from the first cavity and the second cavity when the harvesting tool 11 is in the open state. It is in a state of being compressed and pushed into the hollow portion of the cutting tool 11. From the compressed rice straw, the force (pressure) to return to the original shape acts. When the cutting tool 11 is closed with a branch, the pressure causes the branch to be caught. Therefore, even if the top hole 43 and the bottom hole 45 are not in contact with the branch, The tool 11 will be held. Even from those who do not have a special technique, it is possible to carry out the process from the annular peeling to the installation of the wood removal tool 11 in about 30 seconds to 1 minute. In the tree-cutting method according to the first embodiment, all that is required is to bring a tree-picking tool 11 filled with rice straw and a peeling tool, and work can be performed smoothly.

As a result of the experiment, it was found that the tree-taking method according to the first embodiment can be applied to various trees. We have succeeded in obtaining a tree with a constant rooting rate for cypress trees such as Aomori Hiba, cherry trees such as double cherry blossoms and weeping cherry trees, and other trees such as yew, Japanese maple, and wig. Of these, "Yaezakura" is a general term for cherry blossoms that give flowers to Yaezaki, and is also known as "Kikuzakura." Examples of varieties include Kanzan (Kanyama), Ichiyo (one leaf), Fugenzo (Fugenzo), Yaebeshidare (Yaeko weeping), and the like. According to the method of collecting trees according to the first embodiment, it is possible to obtain a tree with a constant rooting rate even for a double cherry tree that is not suitable for a tree.

According to the tree harvesting method according to the first embodiment, rice is not required to be artificially replenished with water to the rice straws or the like filled in the cavity during several months (tree harvesting period) when sufficient rooting is confirmed. Straws are rarely too dry. From the amount of rice straw required for rooting and the thickness of the branches, etc., the size of the harvesting tool and the appropriate values for the diameter of the top hole and the bottom hole for taking in rainwater were calculated, and then the harvesting tool was designed. It is because it is done.

Further, in the tree-cutting tool described in the invention of Patent Document 1, a large number of small holes for ventilation/water passage were provided, and a rainwater storage tank was separately provided, but the tree-cutting tool according to the first embodiment Since it is not necessary to provide them in the cutting tool used in the method, the manufacturing cost and labor can be greatly reduced.

Furthermore, since the tree-cutting tool used in the tree-cutting method according to the first embodiment can be arbitrarily opened or closed with one touch, it is possible to easily confirm the rooting state from the initial stage of the tree-cutting period. In the conventional technology of applying a thin vinyl sheet, etc., the upper and lower ends of the vinyl sheet are often tied up with a string or tape, so it is not usual to open the container halfway to check the rooting state. is there. In the tree harvesting method according to the first embodiment, the success or failure of rooting can be known from the initial stage, so that tree harvesting can be efficiently performed.

Furthermore, the tree harvesting method according to the first embodiment is less likely to suffer wind and rain and damage to birds and beasts. The conventional technique of applying a vinyl sheet or the like has a problem that the vinyl sheet is exposed to wind and rain and is torn, or birds and beasts are damaged by crows and the like. In the tree harvesting method according to the first embodiment, since these problems hardly occur, it is possible to stably and efficiently obtain tree harvesting.

Furthermore, in the tree harvesting method according to the first embodiment, it is difficult for ants to nest in rice straw or the like that is a filling material for rooting. When ants nest in rice straw and the like, a gap is left between the ring peeling site and rice straw, and the supply of water and the like to the ring peeling site is interrupted, leading to a decrease in rooting rate. In the tree-cutting method according to the first embodiment, a gap between the annular peeling site and rice straw is unlikely to occur. As a result of an experiment conducted by the inventor, it was confirmed that nesting of ants was performed 3 out of 10 times in the method of collecting sphagnum moss as a rooting filler, but the rooting filler was a rice straw according to the first embodiment. By the method, nesting of ants was confirmed once in 10 times. When the tree-cutting method according to the first embodiment was carried out by using sawdust, especially sawdust of Hiba, for rice straw as a filling material for rooting, no nesting of ants was confirmed even once after 10 times of tree-treating treatment. ..

Furthermore, in the tree harvesting method according to the first embodiment, rooting can be carried out faster and more reliably than the method using sphagnum as the rooting filler. Experiments were conducted during the same period of cutting, and when sphagnum moss was used as the rooting filler, it was at the cell division stage before rooting, whereas in the first embodiment in which rice straw was used as the rooting filler. It has been confirmed that several to ten or more roots have already been rooted by the harvesting method. Furthermore, as a rooting filler, rice straw can be prepared at a lower cost than sphagnum.

The first embodiment will be specifically described below with reference to examples, but this is merely for the purpose of illustration, and the first embodiment includes the method, procedure, etc. shown in the following examples. It is not limited to these examples.
[Example 1]

As the tree-cutting tool used in Example 1 of the tree-cutting method according to the first embodiment, a hollow first closed cover portion and a hollow second closed cover portion as shown in FIG.

Was possible. In the open state, the first side wall plate and the second side wall plate are connected only by the connecting portion. In the closed state, the first side wall plate and the second side wall plate are formed as a uniform continuous surface, and the side wall surface formed of the continuous surface is circulated, and the outer shapes of the first closed cover part and the second closed cover part have cavities built therein. To form a columnar shape. A top hole formed by the first and third notches is opened in the upper end surface of the column, and a bottom hole formed by the second and fourth notches is formed in the first bottom plate of the column.

In the middle of June 2019, rice straw was prepared as a filling material for rooting according to Example 1, cut into about 1.5 to 3 cm, and immersed in water for about 10 minutes. The rice straw soaked in water was filled in each of the first closed cover portion and the second closed cover portion of the harvesting tool according to Example 1 in the open state, and the closed state with high sealing level was obtained. ..

Next, as a branch of the tree-cutting treatment according to Example 1, a branch with a diameter of about 1 cm of the rose family Ezonowa Mizuzakura (Padus racemosa Gilib.) growing in a certain place in Aomori prefecture is selected, and a site to be rooted is selected. An annular peeling site was formed by peeling an annular strip having a width of about 2 cm with pruning scissors. Ezonowa Mizuzakura is rarely found in Aomori Prefecture and is designated as the "most important rare wildlife". Next, once the rice harvesting tool filled with rice straw is opened, and about 2 cm each of the annular peeling site and the trunk side and the terminal side of the annular peeling site are covered again with the harvesting wood tool closed. The branches of Ezonowa Mikura were housed in the cavity, top hole and bottom hole.

During the subsequent harvesting period, the harvesting tool was opened several times to check the rooting status each time. After the tree-cutting period of 30 days was completed, the tree-cutting tool according to Example 1 was opened, and it was visually confirmed from the annular peeling site that 10 roots of about 1 cm had rooted. Further, when the rice straw in the portion in contact with the annular peeling site was collected and the number of general viable bacteria was examined, the result was 7.3×10 ⁸ CFU/g. “CFU” of CFU/g is an abbreviation for Colony Forming Unit (Colony Forming Unit) and is a unit of bacterial load.
[Reference Example 1]

As the tree-cutting tool used in Reference Example 1 of the tree-cutting method according to the first embodiment, a tree-cutting tool having the same structure and material as the tree-cutting tool according to Example 1 was prepared. In the middle of June 2019, sphagnum moss was prepared as a rooting filler according to Reference Example 1, and immersed in water for about 10 minutes. The sphagnum moss soaked in water was filled into the inside of each of the first closed cover portion and the second closed cover portion of the cutting tool according to Reference Example 1 in the open state, and the closed state with a high sealing level was obtained.

Next, as a branch for the tree-cutting treatment according to Reference Example 1, similar to the tree-cutting tool according to Example 1, a diameter of about 1 cm of a rose family Ezonowa Mizukura (Padus racemosa Gilib.) growing in a certain place in Aomori Prefecture. Was selected, and the region to be rooted was peeled in an annular shape with a scissors for pruning to a width of about 2 cm to form an annular peeled region. Next, once open the tree harvesting tool filled with sphagnum moss, cover the tree peeling site and the trunk side and the distal side of the ring peeling site about 2 cm each, and close the tree harvesting tool again to cover it. The branches of Nowaiwasakuza were stored in the cavity, the top hole and the bottom hole.

During the subsequent harvesting period, the harvesting tool was opened several times in the same manner as in Example 1, and the rooting condition was confirmed each time. After the tree-cutting period of 30 days, the tree-cutting tool according to Reference Example 1 was opened, but the cell division state before rooting could be visually confirmed, but rooting from the annular peeling site could not be confirmed. It was Further, in the same manner as in Example 1, the sphagnum moss in the portion in contact with the annular peeling site was collected, and the number of general viable bacteria was examined in the same manner as in Example 1. The result was 1.2×10 ⁷ CFU/g. there were. Comparing the general viable cell counts of Example 1 and Reference Example 1, the general viable cell count of Example 1 was about 60 times that of Reference Example 1.

(First Modification of First Embodiment)
As shown in FIG. 4( a ), a cutting tool 11 a _{1 according} to a first modification of the first embodiment has a first closed cover portion 22, and a three-dimensional shape that is a mirror image of the first closed cover portion 22.

The second closed cover portion 24 has a semicircular third notch in the second top plate and a semicircular fourth notch in the second bottom plate.

The cutting tool 11a _{1 according} to the first modified example of the first embodiment is configured such that one of the first closed cover portion 22 and the second closed cover portion 24 is rotationally moved about the coupling portion 42 as an axis. The closed state and the open state (not shown) can be arbitrarily set. As shown in FIG. 4A, the closed state is one of the three first side wall plates of the first closed cover portion 22 and the three second side wall plates of the second closed cover portion 24. One of them is connected to form a continuous surface, and the six side wall plates continuously orbit. By forming a continuous orbiting surface of the six side wall plates, a rectangular parallelepiped hollow portion surrounded by the side wall surfaces of the outer shapes of the first closed cover portion 22 and the second closed cover portion 24 is formed. A top hole 43 formed of a first notch and a third notch is formed in the upper end surface of the rectangular parallelepiped, and a bottom hole formed of a second notch and a fourth notch in the lower end surface of the rectangular parallelepiped. 45 is opened. Although illustration of the open state is omitted, in the open state, the first side wall plate and the second side wall plate are connected only by the connecting portion 42. The cutting tool 11a _{1 according} to the first modification of the first embodiment, in the closed state shown in FIG. 4(a), seals the branch to be cut with the hollow portion, the top hole 43, and the bottom hole 45. Can be accommodated.

As shown in FIG. 4A, the cutting tool 11a _{1 according} to the first modification of the first embodiment has a rectangular parallelepiped shape in the closed state. That is, the cutting tool 11a _{1 according} to the first modified example of the first embodiment has an overall shape in a closed state, in other words, compared with the cutting tool 11 according to the first embodiment shown in FIG. The shapes of the first closed cover part and the second closed cover part are different. The first closed cover portion 22 and the second closed cover portion 24 of the wood removal tool 11a _{1 according} to the first modified example are separated by a line passing through the middle of two opposite sides of the upper end surface and the lower end surface of the square. The open state and the closed state can be arbitrarily set with the joint portion 42 as an axis. The functions and materials of the first closed cover part 22 and the second closed cover part 24 are the same as those of the first closed cover part 21 and the second closed cover part 23. Structures and functions of the first fixing means 31, the second fixing means 33, the top hole 43, the bottom hole 45, and the connecting portion 42, which are other structures of the cutting tool 11a _{1 according} to the first modified example of the first embodiment. Is the same as the corresponding part of the tree-cutting tool 11 according to the first embodiment, and thus the description thereof will be omitted. The usage method of the tree-cutting tool 11a _{1 according} to the first modification of the first embodiment is the same as that of the tree-cutting tool 11 according to the first embodiment.

When using the tree-cutting tool 11a _{1 according} to the first modified example of the first embodiment, as in the case of the tree-cutting tool 11 according to the first embodiment, a special technique from annular peeling to installation of the tree-cutting tool 11a ₁ Even a person who does not have the above can perform it in about 30 seconds to 1 minute. In the tree-cutting process using the tree-cutting tool 11a _{1 according} to the first modification, it is sufficient to bring only the tree-cutting tool 11a ₁ filled with the rooting filler and the peeling tool, and the work can be performed smoothly. The types of trees to which the harvesting tool 11a ₁ can be applied are the same as those of the harvesting tool 11 according to the first embodiment, and succeeded in obtaining harvests with various trees at a constant rooting rate. There is.

When the tree-cutting tool 11a _{1 according} to the first modification is used, as in the case of the tree-cutting tool 11 according to the first embodiment, the hollow portion is formed during several months (tree-cutting period) when sufficient rooting is confirmed. Even if the root filling material such as sphagnum moss filled in the above is not artificially supplemented with water, the sphagnum moss is hardly dried too much. Based on the amount of sphagnum required for rooting, the thickness of the branches, and the like, appropriate values for the dimensions of the harvesting tool 11a ₁ and the diameters of the top hole 43 and bottom hole 45 for taking in rainwater are calculated, and then This is because the wood removal tool 11a _{1 according} to the modification is designed.

Further, in the tree-grabbing tool described in the invention of Patent Document 1, a large number of small holes for ventilation/water passage were provided, and a rainwater storage tank was separately provided. Since it is not necessary to provide them in the tool 11a ₁ , the manufacturing cost and labor can be greatly reduced.

Furthermore, since the tree-cutting tool 11a _{1 according} to the first modification can be arbitrarily opened or closed with one touch, the rooting state can be easily confirmed from the initial stage of the tree-cutting period. In the conventional technology of applying a thin vinyl sheet, etc., the upper and lower ends of the vinyl sheet are often tied up with a string or tape, so it is not usual to open the container halfway to check the rooting state. is there. When the tree-cutting tool 11a _{1 according} to the first modification is used, the success or failure of rooting can be known from the initial stage, and thus a tree-cutting can be efficiently produced.

Furthermore, the tree-cutting tool 11a _{1 according} to the first modification is resistant to wind and rain and damage to birds and beasts. The conventional technique of applying a vinyl sheet or the like has a problem that the vinyl sheet is exposed to wind and rain and is torn, or birds and beasts are damaged by crows and the like. When the tree-cutting tool 11a _{1 according} to the first modified example is used, these problems hardly occur, and therefore a tree-cut can be stably and efficiently obtained.

Furthermore, in the tree-cutting tool 11a _{1 according} to the first modified example, since appropriate numerical values for the diameters of the top hole 43 and the bottom hole 45 are calculated, ants are found in sphagnum moss and the like that is a filling material for rooting. It is difficult to nest. When an ant nests in sphagnum moss, a gap is left between the ring peeling site and sphagnum moss, and water supply to the ring peeling site is interrupted, leading to a decrease in rooting rate. By using the wood removal tool 11a _{1 according} to the first modification, it is possible to suppress the invasion of ants from the top hole 43 and the bottom hole 45, and thus a gap between the annular peeling site and sphagnum moss is unlikely to occur.

Is the same. The structures and functions of the first fixing means 31, the second fixing means 33, and the coupling portion 41, which are the other structures of the cutting tool 11d according to the fourth embodiment, are equivalent to those of the cutting tool 11 according to the first embodiment. It is similar to the part to do.

When the tree-cutting tool 11d according to the fourth embodiment is used, even if the person does not have any special technique from the annular peeling to the installation of the tree-cutting tool 11d, as in the case of the tree-cutting tool 11 according to the first embodiment, 30 It can be performed in about a second to 1 minute. In the tree-cutting processing using the tree-cutting tool 11d according to the fourth embodiment, it is sufficient to bring only the tree-cutting tool 11d filled with the rooting filler and the peeling tool, and the work can be performed smoothly. The types of trees to which the harvesting tool 11d can be applied are the same as in the case of the harvesting tool 11 according to the first embodiment, and various trees have been successfully obtained with a constant rooting rate. ..

When the tree-grabbing tool 11d according to the fourth embodiment is used, as in the case of the tree-grabbing tool 11 according to the first embodiment, the hollow portion is formed in a cavity for several months (tree-cutting period) when sufficient rooting is confirmed. Even if the filled sphagnum or the like is not artificially replenished with water, the sphagnum or the like is hardly dried too much. From the amount of sphagnum required for rooting, the thickness of the branches, etc., the appropriate values for the dimensions of the harvesting tool 11d and the diameters of the top hole 43 and the bottom hole 45 for taking in rainwater are calculated, and then the fourth implementation This is because the cutting tool 11d according to the embodiment is designed.

Further, in the tree-cutting tool described in the invention of Patent Document 1, a large number of small holes for ventilation/water passage were provided, and a rainwater storage tank was separately provided. However, the tree-cutting tool according to the fourth embodiment Since it is not necessary to provide them in the tool 11d, the manufacturing cost and labor can be greatly reduced. In addition, in the cutting tool 11d according to the fourth embodiment, since the upper portion is recessed toward the top hole 43, more moisture such as rainwater can be removed from the top hole 43 as compared with the structure without depression. Can be captured. Further, in the wood-cutting tool 11d according to the fourth embodiment, since the lower portion is recessed toward the bottom hole 45, the moisture taken in the edge portion of the lower portion of the cavity is compared to the structure in which it is not recessed. It is possible to store it, and it is possible to make it difficult for the water that has entered the cavity to escape from the bottom hole 45.

Furthermore, since the tree-cutting tool 11d according to the fourth embodiment can be arbitrarily opened or closed with one touch, it is possible to easily confirm the rooting state from the initial stage of the tree-cutting period. In the conventional technology of applying a thin vinyl sheet, etc., the upper and lower ends of the vinyl sheet are often tied up with a string or tape, so it is not usual to open the container halfway to check the rooting state. is there. When the cutting tool 11d according to the fourth embodiment is used, the success or failure of rooting can be known from the initial stage, so that a cutting tree can be efficiently created.

Furthermore, the harvesting tool 11d according to the fourth embodiment is resistant to wind and rain and damage to birds and animals. The conventional technique of applying a vinyl sheet or the like has a problem that the vinyl sheet is exposed to wind and rain and is torn, or birds and beasts are damaged by crows and the like. By using the tree-cutting tool 11d according to the fourth embodiment, since these problems hardly occur, the tree-cutting can be stably and efficiently obtained.

Further, in the cutting tool 11d according to the fourth embodiment, since appropriate numerical values of the diameters of the top hole 43 and the bottom hole 45 are calculated, an ant nests in sphagnum moss or the like as a rooting filler. Hard to do. When an ant nests in sphagnum moss, a gap is left between the ring peeling site and sphagnum moss, and water supply to the ring peeling site is interrupted, leading to a decrease in rooting rate. When the cutting tool 11d according to the fourth embodiment is used, it is possible to suppress the invasion of ants from the top hole 43 and the bottom hole 45, and thus a gap between the annular peeling site and sphagnum moss is unlikely to occur.

Furthermore, in the tree-cutting tool 11d according to the fourth embodiment, the tree-cutting process is continued even when the target branch grows thicker than the top hole 43 and the bottom hole 45 by several mm during the tree-cutting process. it can. The cutting tool 11d according to the fourth embodiment has a structure in which the first top plate and the first bottom plate are respectively recessed toward the cavity, so that when the branch to be cut becomes slightly thicker, the top hole can be easily removed. 43 and the bottom hole 45 expand, and the first top plate and the first bottom plate are deformed so as to be closer to the hollow portion side than usual. Then, the first side wall plate of the first closed cover portion 25 and the second side wall plate of the second closed cover portion 26, which are in the closed state, are 0.5 to 2 around the top hole 43 and the bottom hole 45. Separate about 0.0 mm. At this time, the connection between the first fixing means 31 and the second fixing means 33 is not disengaged, and, of course, the connecting portion 41 is not cracked or otherwise damaged. When the tree-cutting tool 11d according to the fourth embodiment is used, the tree-cutting process can be continued until the desired rooting state is obtained without damaging or pressing the grown branch. Since there is a gap formed between the first closed cover portion and the second closed cover portion 26, the tree-cutting tool 11d according to the fourth embodiment during the tree-cutting process is not in a completely sealed state. It is possible to take in a suitable amount of rainwater, etc., and to discharge excess water inside. Furthermore, since this gap is about 2.0 mm at the maximum, the rooting filler in the cavity does not dry too much, and the invasion of ants can be suppressed. The first top plate and the first bottom plate of the harvesting tool 11d according to the fourth embodiment may each have a radial cut centering on the center of the top hole 43 or the bottom hole 45. Due to this cut, when the target branch grows thicker than the top hole 43 and the bottom hole 45 by several mm during the cutting process, pressure (stress) on the grown branch can be further reduced.

The "connection-side end" is one end along the longitudinal direction of the gutter, and the end opposite to the connection-side end is defined as the "open/close-side end". A frame-shaped first fixing means 31 is provided on a part of the outer wall surface of the opening/closing side end of the first side wall plate of the first closed cover part 29, and the second side wall plate of the second closed cover part 30 is provided with the frame-shaped first fixing means 31. A rod-shaped second fixing means 33 is provided on a part of the outer wall surface of the opening/closing side end portion. The first fixing means 31 and the second fixing means 33 constitute a switching fastener capable of switching the binding in the open/closed state with one touch. The first closed cover portion 29 has a semicircular first notch on the first top plate and a semicircular second notch on the first bottom plate. The second closed cover portion 30 has a semicircular third notch on the second top plate and a semicircular fourth notch on the second bottom plate. In the woodcutting tool 11e according to the fifth embodiment, one of the first closed cover portion 29 and the second closed cover portion 30 is rotationally moved about the coupling portion 41 as an axis, and thus the closed state and the open state. And can be arbitrarily set. In the “closed state”, as shown in FIG. 9, the first side wall plate of the first closed cover portion 29 and the second side wall plate of the second closed cover portion 30 form a continuous continuous circumferential surface. It forms a truncated cone shape.

The top hole 43 formed by the cutout is opened, and the bottom hole 45 formed by the second cutout and the fourth cutout is opened in the first bottom plate of the inverted truncated cone. Although illustration of the "open state" is omitted, the first side wall plate and the second side wall plate are in an open state in which they are connected only by the connecting portion 41. The cutting tool 11e according to the fifth embodiment is similar to that shown in FIG. 3 in that the branch to be cut is hermetically housed through the top hole 43 and the bottom hole 45, so that the first sealing The inverted truncated cone formed by the cover portion 29 and the second closed cover portion 30 can be closed. In the closed state, the wood-cutting tool 11e according to the fifth embodiment is in a state in which the cavity of the wood-cutting tool 11e communicates with the outside only through the top hole 43 and the bottom hole 45.

Considering how to plant in soil after planting the trees and how to plant roots, the truncated cone shape is narrowed from the upper part to the lower part as shown in FIG. 9, that is, the surface of the first top plate is 1 An inverted truncated cone shape having an area larger than the surface of the bottom plate is a preferable shape. As shown in FIG. 9, when a truncated cone shape that narrows from the upper part to the lower part is adopted and the height is about 8.0 cm, the diameter of the upper part is 3.5 to 4.5 cm, and the lower part is The diameter is preferably 2.5 to 3.5 cm. These values are the result of comprehensive consideration of the ease of plant root tension, the amount of sphagnum moss, etc., which is a filling material for rooting, the burden on the branches by weight, and the sufficient coverage of the peeled parts of the branches. It is a numerical value calculated by the researchers through repeated experiments.

The materials of the first closed cover part 29 and the second closed cover part 30 are the same as those of the first closed cover part 21 and the second closed cover part 23 of the cutting tool 11 according to the first embodiment. .. The top hole 43 and the bottom hole 45 have the same structure and function as the top hole 43 and the bottom hole 45 of the cutting tool 11 according to the first embodiment in the closed state shown in FIG. 9. The structures and functions of the first fixing means 31, the second fixing means 33, and the coupling portion 41, which are the other structures of the woodcutting tool 11e according to the fifth embodiment, are equivalent to those of the woodcutting tool 11 according to the first embodiment. It is similar to the part to do.

When the tree-cutting tool 11e according to the fifth embodiment is used, even in the case of the tree-cutting tool 11 according to the first embodiment, even a person who does not have a special technique from the annular peeling to the installation of the tree-cutting tool 11e is 30 It can be performed in about a second to 1 minute. In the tree-cutting process using the tree-cutting tool 11e according to the fifth embodiment, it is only necessary to bring the tree-cutting tool 11e filled with the rooting filler and the peeling tool, and the work can be performed smoothly. The types of trees to which the harvesting tool 11e can be applied are the same as in the case of the harvesting tool 11 according to the first embodiment, and various trees have been successfully obtained with a constant rooting rate. ..

When the tree-grabbing tool 11e according to the fifth embodiment is used, as in the case of the tree-grabbing tool 11 according to the first embodiment, the hollow portion is formed in the cavity during several months (tree-cutting period) when sufficient rooting is confirmed. Even if the filled sphagnum or the like is not artificially replenished with water, the sphagnum or the like is hardly dried too much. From the amount of sphagnum required for rooting, the thickness of branches, etc., the fifth value is calculated after calculating the dimensions of the harvesting tool 11e and the diameters of the top hole 43 and the bottom hole 45 for taking in rainwater. This is because the cutting tool 11e according to the embodiment is designed.

In addition, in the tree-cutting tool described in the invention of Patent Document 1, a large number of small holes for ventilation/water passage were provided, and a rainwater storage tank was separately provided. However, the tree-cutting tool according to the fifth embodiment Since it is not necessary to provide them in the tool 11e, the manufacturing cost and labor can be greatly reduced.

Furthermore, since the tree-cutting tool 11e according to the fifth embodiment can be arbitrarily opened or closed with one touch, it is possible to easily confirm the rooting state from the initial stage of the tree-cutting period. In the conventional technology of applying a thin vinyl sheet, etc., the upper and lower ends of the vinyl sheet are often tied up with a string or tape, so it is not usual to open the container halfway to check the rooting state. is there. By using the tree-cutting tool 11e according to the fifth embodiment, the success or failure of rooting can be known from the initial stage, and thus the tree-cutting can be efficiently produced.

Furthermore, the harvesting tool 11e according to the fifth embodiment is resistant to wind and rain and damage to birds and animals. The conventional technique of applying a vinyl sheet or the like has a problem that the vinyl sheet is exposed to wind and rain and is torn, or birds and beasts are damaged by crows and the like. When the tree-cutting tool 11e according to the fifth embodiment is used, these problems hardly occur, so that the tree-cutting can be stably and efficiently obtained.

Further, in the tree-cutting tool 11e according to the fifth embodiment, since appropriate numerical values of the diameters of the top hole 43 and the bottom hole 45 are calculated, ants nest in sphagnum moss or the like that is a filling material for rooting. Hard to do. When an ant nests in sphagnum moss, a gap is left between the ring peeling site and sphagnum moss, and water supply to the ring peeling site is interrupted, leading to a decrease in rooting rate. By using the wood removal tool 11e according to the fifth embodiment, it is possible to suppress the invasion of ants from the top hole 43 and the bottom hole 45, and thus a gap between the annular peeling site and sphagnum moss is unlikely to occur.

Furthermore, in the tree-cutting tool 11e according to the fifth embodiment, since it has a truncated cone shape that narrows from the upper part to the lower part, it is more suitable for rooting than the cylindrical tree-cutting tool having the same diameter from the upper part to the lower part. The amount of the filler can be reduced, and the rooted root can be stretched further downward. The roots of plants play a role of supporting plant bodies as well as absorbing fertilizer components and water. The plants subject to the harvesting method are trees, and in particular, the "role of supporting the plant body" of the root has a large weight, and the root extending downward is very important. Roots tend to grow downward in the direction of gravity, but they also spread horizontally depending on the shape of the cutting tool. When planting at a desired location after harvesting trees, for harvesting trees that have roots that expand in the horizontal direction, you must dig a large amount of soil when planting as is, and even if planted, the function to support the plant is weak. The roots that have spread horizontally may be shaped downward before they are planted, but it is easy to damage the roots, and this may cause the tree to weaken from that part. At the end of the harvesting process, the roots are concentrated and stretched further downward, and since the planting can be done in the same shape, it does not damage the roots, it does not take time and the plant Since it has a high support function, it tends to grow well after planting.

The structure and function of the top hole 43 and the bottom hole 45 of the cutting tool 11f according to the sixth embodiment are the same as those of the cutting tool 11 according to the first embodiment. The structures and functions of the first fixing means 31 and the second fixing means 33, which are the other structures of the cutting tool 11f according to the sixth embodiment, are the same as the corresponding portions of the cutting tool 11 according to the first embodiment. Is.

With the use of the tree-cutting tool 11f according to the sixth embodiment, as with the case of the tree-cutting tool 11 according to the first embodiment, even a person who does not have a special technique from annular peeling to installation of the tree-cutting tool 11f is 30 It can be performed in about a second to 1 minute. In the tree-cutting process using the tree-cutting tool 11f according to the sixth embodiment, it is only necessary to bring the tree-cutting tool 11f filled with the rooting filler and the peeling tool, and the work can be performed smoothly. The types of trees to which the harvesting tool 11f can be applied are similar to those of the harvesting tool 11 according to the first embodiment, and various trees have been successfully obtained with a constant rooting rate. ..

When the tree-cutting tool 11f according to the sixth embodiment is used, like the case of the tree-cutting tool 11 according to the first embodiment, the hollow portion is formed in the cavity during several months (tree-cutting period) when sufficient rooting is confirmed. Even if the filled sphagnum or the like is not artificially replenished with water, the sphagnum or the like is hardly dried too much. From the amount of sphagnum required for rooting, the thickness of branches, etc., the sixth value is calculated after calculating the dimensions of the harvesting tool 11f and the diameters of the top hole 43 and the bottom hole 45 for taking in rainwater. This is because the cutting tool 11f according to the embodiment is designed.

Further, in the tree-cutting tool described in the invention of Patent Document 1, a large number of small holes for ventilation/water passage were provided, and a rainwater storage tank was separately provided, but the tree-cutting tool according to the sixth embodiment Since it is not necessary to provide them in the tool 11f, the manufacturing cost and labor can be greatly reduced.

Furthermore, since the tree-cutting tool 11f according to the sixth embodiment can be arbitrarily opened or closed with one touch, it is possible to easily confirm the rooting state from the initial stage of the tree-cutting period. In the conventional technology of applying a thin vinyl sheet, etc., the upper and lower ends of the vinyl sheet are often tied up with a string or tape, so it is not usual to open the container halfway to check the rooting state. is there. When the cutting tool 11f according to the sixth embodiment is used, the success or failure of rooting can be known from the initial stage, so that a cutting tree can be efficiently created.

Furthermore, the harvesting tool 11f according to the sixth embodiment is resistant to wind and rain and damage to birds and animals. The conventional technique of applying a vinyl sheet or the like has a problem that the vinyl sheet is exposed to wind and rain and is torn, or birds and beasts are damaged by crows and the like. By using the tree-cutting tool 11f according to the sixth embodiment, since these problems hardly occur, the tree-cutting can be stably and efficiently obtained.

Furthermore, in the harvesting tool 11f according to the sixth embodiment, since appropriate numerical values of the diameters of the top hole 43 and the bottom hole 45 are calculated, ants nest in sphagnum moss or the like as a rooting filler. Hard to do. When an ant nests in sphagnum moss, a gap is left between the ring peeling site and sphagnum moss, and water supply to the ring peeling site is interrupted, leading to a decrease in rooting rate. By using the harvesting tool 11f according to the sixth embodiment, it is possible to suppress the invasion of ants from the top hole 43 and the bottom hole 45, and thus a gap between the annular peeling site and sphagnum moss is unlikely to occur.

Furthermore, in the tree-cutting tool 11f according to the sixth embodiment, since it is a rice ball shape that spreads from the upper part to the lower part, the amount of the rooting filler is larger than that of the column-shaped tree-cutting tool having the same diameter from the upper part to the lower part. And the rooted root can be stretched in the lateral direction (horizontal direction). Some plant roots are easy to pull in the gravity direction (vertical direction) and the other are easy to pull in the lateral direction (horizontal direction). For plants where the roots are preferably stretched laterally (horizontally), the horizontal obstruction is stressful. As the tree-grabbing tool that does not apply stress, a conical shape that spreads from the upper part to the lower part, a truncated cone shape that is the inverted tree-cutting tool 11e according to the fifth embodiment of FIG. 9, or the sixth embodiment of FIG. A rice ball shape such as the harvesting tool 11f is preferable. In the tree-cutting tool 11f according to the sixth embodiment, the roots can be rooted in an environment with less stress for plants whose roots are preferably stretched in the lateral direction (horizontal direction), and therefore the growth after planting is likely to be good.
