Description

  The present invention relates to a container that can be used consistently not only from the production to planting of trees but also from the rearing to the removal after planting.

  In recent years, the heat island phenomenon, which is a phenomenon in which the temperature in the city center is higher than the temperature in the suburbs, has been a problem. The cause of this heat island phenomenon is the increase of artificial heat exhausted from human activities such as air conditioning systems, electrical equipment, combustion equipment, and automobiles, the reduction of green spaces and water surfaces, and the artificial surface of the ground due to the increase of buildings and paved surfaces Is mentioned.

  As one of the countermeasures against the heat island phenomenon, greening of the city center is being promoted. Plants perform transpiration, which is a phenomenon in which water in the body is discharged out of the body as water vapor. And when the water vapor | steam transpired from a plant vaporizes, ambient temperature is reduced with the heat of vaporization. Such an effect is called a transpiration effect. Therefore, by promoting greening in the city center, attempts have been made to reduce the temperature and mitigate the heat island phenomenon by the transpiration effect.

  In general, trees that are artificially planted are produced in a production facility. The produced trees are dug up from the ground when shipped. At this time, the roots spreading in the soil are partially cut (rooting). And in order to maintain the balance of transpiration with the roots cut by the root turning, the tree branches are pruned.

  Next, in order to prevent the root pot from collapsing during transportation, the root portion dug up is wound up with a root winding material and wound around. Here, the root pot is a root portion dug by adding soil to the root portion. If the root pot collapses, the root is damaged and weakened.

  After that, to make it easier to transport the trees, the branches are gathered with ropes and the branches are folded. Thus, the tree processed for conveyance is conveyed to a planting place. And a root pot is put in the hole dug in the soil beforehand, and it is planted (planted).

  As a tree used for such planting, for example, Patent Document 1 discloses a container tree in which a net material is embedded in a planting base material. According to Patent Document 1, since the roots of a tree are entangled with a net material, an integral structure can be formed with a base material even if the roots do not grow sufficiently. As a result, early shipment of container trees is possible.

Patent Document 2 discloses a flower pot molded from a biodegradable plastic. According to Patent Document 2, since the flower pot will eventually decompose and disappear in the soil, the replanting is completed by burying the whole plant pot, avoiding the death due to the occurrence of root breakage of the plant, making the replanting work easier. As a result, the labor saving on the user side can be achieved, and the handling of the load from production to shipping can be automated to achieve the labor saving on the producer side.

  However, there is very little exposed ground in the city center. Buildings and houses are built with high efficiency on most land, and there is not enough room to plant trees on each plot. In addition, land users frequently change in the city center, so plants may be forced to be removed. If large trees are firmly rooted, there is a problem that the removal work takes excessive labor and cost. For these reasons, in the city center, how to efficiently plant in a small area and how to reduce the planting and removal work becomes a challenge.

  The container tree concerning patent document 1 is extracted from the inside of a container in the case of planting, and is planted in a planting site. And the planted tree is nurtured in a planting place. At the time of such breeding, the roots of the trees are not restrained in the growth direction, so the roots circulate in the soil in all directions. Moreover, also in the flowerpot concerning patent document 2, after a flowerpot lose | disappears, it will be in the same state as the plant having been just planted.

  At this time, if the planting area of the tree is a place where the site area is large, there is no buried structure in the soil, and the grown tree is not removed, there will be no problem due to the growth of the tree roots. . However, in the planting areas in the city center, if the trees after breeding become unnecessary due to the change of land users or the rebuilding of buildings, the trees must be removed. Also, when the tree dies, it needs to be removed. In removing such a tree, it is necessary to dig up the soil deeply, cut the main roots and straight roots stretched in the soil, dig up the tree, and a great deal of labor is required at the time of removal. Further, in order to dig deeply, it is necessary to take a large work place, but it may be difficult to secure the work place in a narrow area such as a residential area or a building area.

  Furthermore, in the planting sites in the city center described above, the buildings are lined up adjacent to the narrow planting sites, and the foundations of such buildings and pipes such as water pipes and gas pipes are buried in the soil. . Then, the roots that have grown, especially the side roots that grow in the circumferential direction around the trees, have a problem in that the foundation of the building is adversely affected and the pipes are pushed up and damaged.

  Therefore, the present invention can be used not only from tree production to planting but also from planting to removal after planting, improving production and transport efficiency, and reducing the burden on trees. The purpose is to provide a simple container.

  In order to solve the above problems, a typical configuration of a tree planting / growing container according to the present invention includes a frame, a bottom surface having root-preventing properties, and a side wall having biodegradability. Features.

  With such a configuration, the side wall of the container buried in the soil is biodegraded and disappears after a predetermined period of time. Therefore, tree roots (side roots) can grow in the direction of the side wall in the soil. Thereby, it is possible to plant the tree grown in the container together with the container without removing it from the container and further grow it in the soil.

  Moreover, according to the said structure, it can plant in a planting ground, without performing rooting and pruning of a tree in planting from production of a tree. Thereby, in order to reduce the damage to a tree by cutting of a root or pruning of a branch, it becomes possible to improve the survival rate of the tree in a planting site.

  A biodegradable mesh sheet, a biodegradable plate, a biodegradable film, etc. can be used for such a side wall. In addition, the biodegradable material is preferably a material having a period required for biodegradation of about 3 to 5 years. This is because the period from the growth of trees to shipment and planting is about this level, and when the side walls disappear by biodegradation before shipment, the soil that is the culture medium of the trees is lost.

  In addition, since the biodegradable side wall is provided for the frame, the frame remains in the soil even after the side wall is biodegraded. Therefore, when removing the trees, the soil can be removed by lifting and lifting the frame to easily remove the plants. And also at the time of the conveyance for planting and removal of a tree, since a frame is provided, the load resistance is high, and it can be conveyed with the tree planted. Therefore, it is not necessary to secure a wide working place, and the workability in a narrow area can be improved.

  In addition, after excision of the side roots that extend outside the frame, the container (frame) can be removed (collected) while the tree is planted as described above. It is possible to plant the entire container in the relocation site. Therefore, it is possible to reduce the damage when moving to trees that are no longer needed at the planting site, and to improve the survival rate of trees at the relocation site, so that the trees after removal can be reused efficiently It is.

  Moreover, the growth direction of the root of the tree after planting, especially a straight root can be suppressed because a bottom face has root-proof property and does not have biodegradability. As a result, the length of the straight root is within the height of the container. Therefore, when removing the grown tree, it is only necessary to dig the soil up to the height of the container, thereby reducing labor. In this respect as well, it is not necessary to secure a wide working place, and workability in a narrow area can be improved.

  The bottom surface may be formed by fitting a plastic plate or the like to the frame. Thereby, the material etc. of the member of a bottom face can be changed suitably. Further, the bottom surface may be molded integrally with the frame body. Thereby, production costs can be reduced.

  Furthermore, when the surrounding soil is very poor in water drainage, holes can be provided on the bottom surface. Thereby, it is possible to promote water drainage inside the container and prevent tree root rot.

  Said frame is good in a substantially rectangular parallelepiped.

  With this configuration, space saving during transportation can be achieved. In addition, there are many narrow areas in the city center, and there is a possibility that the area of the planted area is also small. In such a case, it is assumed that the plant is planted on the boundary line of the site as a site or along the outer wall of the building. Therefore, when the container frame is a substantially rectangular parallelepiped, it can be planted in such a band-like (linear) narrow land, and a limited space can be used effectively.

  Moreover, with this shape, a plurality of containers can be juxtaposed without gaps, and the area of the planting land can be used effectively. Further, the trees are installed at almost equal intervals due to the above shape. Therefore, planting with excellent appearance can be easily performed without measuring the interval between trees.

  The frame body is a vent water pipe having at least a vertical frame having a space inside, and the vent water pipe may be opened at an upper end portion of the frame body and have a large number of small holes.

  With this configuration, it is possible to easily perform aeration (irrigation) and irrigation to the roots in the soil. Therefore, labor required for maintenance such as aeration and irrigation in growing trees after planting is reduced, and water and air are not insufficient even in a narrow area. Therefore, it is possible to grow well after planting and to simplify the management process.

  For example, when water is poured into the opening at the upper end of the frame body, the water flows into a gap inside the ventilation water pipe. And water is supplied to the soil which is a culture medium in a container through many small holes from this space | gap. Thereby, it is possible to irrigate the roots of the trees in the container.

  As the above vent water pipe, a hollow pipe made of metal or plastic can be used. This makes it possible to easily send air or inject water into the frame.

  Moreover, a capillary tube material or a porous material can be filled into the hollow tube. Such porous materials and capillary materials have a large number of small holes. For example, by using a hollow tube as the vent water conduit and filling the hollow tube with pumice, which is a porous material, the water holding power of the vent conduit is improved. Therefore, it is possible to gently permeate water into the soil that is the culture medium in the container.

  Furthermore, as another example of the above-described vent water pipe, the vent water pipe itself can be formed of a porous material such as pumice or a capillary material. As a result, the entire frame can be provided with aeration and irrigation functions. For example, the air vent pipe itself is made of pumice, the entire frame body is provided with aeration and irrigation functions, and the air vent pipe is encapsulated with a nonwoven fabric or a mesh sheet. It is possible to prevent soil from entering the ground.

  The side wall of the frame body may be provided with a removable root prevention panel.

  With this configuration, it is possible to suppress the growth direction of tree roots, particularly side roots. For example, in a planting site, when there are pipes in the vicinity of the place where the container is installed, by attaching a root prevention panel to the side wall adjacent to the pipe etc., the growth direction of the side roots in the side wall direction can be suppressed. . That is, by controlling the root growth direction in a narrow area where the presence of underground objects is predicted at a close distance, the influence of the plant on the underground objects can be eliminated.

  A side surface of the frame body may be provided with a connecting portion for fixing the frame body in a state of being aligned with another frame body.

  With this configuration, when arranging a plurality of containers, the positions of the plurality of containers can be easily aligned even if the shape of the excavated grooves (holes) is somewhat irregular. It becomes. The connecting portion may be integrally formed with the frame. Thereby, the intensity | strength of the said connection part can be improved. Moreover, the said connection part can also be made into a member different from a frame. Thereby, the said connection part can be attached or detached to a frame as needed.

  On the side surface of the frame body, it is preferable that a support ring for inserting and supporting the support column is provided so as to protrude substantially horizontally.

  With this configuration, the support for supporting the tree can be easily fixed to the container. As a result, it is possible to prevent the tilting of trees that are unstable. Note that the support ring may be integrally formed with the frame. Thereby, the intensity | strength of the said support | pillar ring can be improved. Moreover, the said support | pillar ring can also be made into a member different from a frame. Thereby, the said support | pillar ring can be attached or detached to a frame as needed.

  According to the present invention, it can be used not only from the production of trees to planting but also from the rearing to the removal after planting, improving the production and transportation efficiency, and reducing the burden on the trees. Possible containers can be provided.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not related to the present invention are not illustrated. .

[First Embodiment]
FIG. 1 is a diagram illustrating a container according to the first embodiment. Fig.1 (a) is an external view of the container concerning 1st Embodiment, FIG.1 (b) is an external view of the container concerning 1st Embodiment which attached the accessory. 2A and 2B are diagrams for explaining the structure of the container according to the first embodiment, in which FIG. 2A is a container in which a tree is implanted, FIG. 2B is a cross-sectional view taken along the line AA of FIG. (C) is BB sectional drawing of a container.

  The container 100 includes a frame body 110, a side wall 120 having biodegradability, and a bottom surface 130 having a root-preventing property (see FIG. 2B). The frame body 110 includes a panel guide 142 for attaching the root prevention panel 140 and a connecting portion 150 for connecting the frame bodies. Further, the container 100 is provided with a root prevention panel 140, a support ring attachment 162 for standing and inserting a support, and an end cap 114 for sealing the upper opening of the frame 110. it can. The container 100 is filled with soil 104 as a medium, and a tree 102 is planted and grown (see FIG. 2A), and the root 102a of the tree 102 grows in the soil 104 (see FIG. 2B). ).

  The frame 110 is made of a rigid body such as metal or synthetic resin. As a result, the container 100 has a high load resistance and can be transported while trees are planted.

  The frame 110 is a substantially rectangular parallelepiped, that is, the outer shape of the container 100 is a substantially rectangular parallelepiped. Thereby, the space saving at the time of cultivation and transportation can be achieved. Moreover, in the planting work in a narrow planting place in the city center, the work can be performed in a narrow space, and the workability in the narrow land can be improved.

  Further, in the planting place in the city center, the tree 102 (container 100) is planted in a narrow strip (line) along the boundary line (outside) of the site or the outer wall of the building. It is assumed that Even in such a case, since the container 100 is a substantially rectangular parallelepiped, it is possible to effectively use a limited space of such a band-like (linear) narrow land.

  Moreover, since the container 100 is a substantially rectangular parallelepiped, the several container 100 can be arranged in parallel without a gap, and the area of a planting land can be used effectively. As a result, the trees 102 are installed at substantially equal intervals, so that planting with excellent appearance can be easily performed.

  In the frame 110, at least the vertical frame is configured by an aeration water pipe (aeration pipe) having a gap inside. Such a vent pipe has an opening 112 at the upper end and a large number of small holes 116 in the soil (see FIG. 2C). With the above configuration, the air sent from the opening 112 and the injected water flow into the gap inside the ventilation pipe, and are supplied from the gap to the soil 104 in the container through the many small holes 116. Therefore, aeration and irrigation of the root 102a in the soil 104 can be easily performed. In addition, the horizontal frame of the frame 110 is also a vented water pipe, and by communicating with the vertical frame, aeration and watering to the root 102a in the soil 104 can be performed more efficiently.

  As a result, it is possible to reduce labor required for maintenance such as aeration and irrigation in growing the tree 102 after planting. This also allows water and air to be sufficiently supplied to the tree 102 even in a small area, so that the tree 102 after planting can be grown well and the management process can be simplified.

  Further, an end cap 114 can be attached to the opening 112. Thereby, it is possible to prevent the soil 104 and dust from entering the gap of the frame body 110 (ventilating water pipe) from the opening 112, and the clogging of the frame body 110 can be avoided.

  In the first embodiment, the hollow portion of the vent water pipe is filled with pumice 118, which is a porous material (see FIG. 2C). As a result, the water holding power of the ventilation water pipe is improved, and it is possible to gently permeate water into the soil that is the culture medium in the container.

  The side wall 120 is composed of a biodegradable mesh sheet having biodegradability. Therefore, when the container 100 is buried in the soil, the side wall 120 is biodegraded and disappears after a predetermined date. Thereby, the root (side root) of the tree 102 can grow in the side wall direction in the soil, and the tree 102 grown in the container 100 can be planted together with the container 100 and further grown in the soil.

  Therefore, the tree 102 can be grown, transported, and planted while being planted in the container 100. That is, since the entire container 100 can be planted, there is no need to perform rooting and pruning when the tree 102 is shipped. Further, by growing the tree 102 in the container 100, the root of the tree 102 grows within a range that fits inside the substantially rectangular parallelepiped frame 110. Therefore, it is not necessary to cut the root of the tree 102. Thereby, the damage to the tree 102 by the cutting | disconnection of a root or the pruning of a branch can be reduced, and the survival rate of the tree 102 in a planting site can be improved.

  A biodegradable material such as a biodegradable plate or a biodegradable film may be used for the sidewall 120. The biodegradable material used for the sidewall 120 may be biodegraded in about 3 to 5 years. This is because the period from tree growth to shipment and planting is approximately this level. If the side wall 120 disappears by biodegradation before shipment, the soil that is the medium of the tree 102 is lost.

  With the configuration described above, in the container 100 embedded in the soil, the side wall 120 disappears due to biodegradation after a predetermined period of time, and the frame 110 remains in the soil. Therefore, when the tree 102 is removed, the soil can be removed by lifting and shaking the frame 110, and the tree 102 can be easily removed.

  The bottom surface 130 is made of a non-biodegradable material and has root-proofing properties. With this configuration, it is possible to suppress the growth direction of the root of the tree 102 after planting, particularly the straight root. Therefore, the length of the straight root after the growth is within the height of the container, and the labor for excavation when removing the tree 102 can be reduced. In addition, this makes it possible to improve workability even in a narrow area where it is difficult to secure a work place.

  The bottom surface 130 can be integrally formed with the frame body 110 when the frame body 110 is formed of a synthetic resin. Thereby, production cost can be reduced. When the frame body 110 is made of a metal such as iron, the bottom surface 130 may be a separate member from the frame body 110, or a plastic plate or the like may be used as the bottom surface 130 and fitted to the frame body 110. Thereby, the material etc. of the bottom face 130 can be changed suitably. Moreover, when the surrounding soil is extremely poor in water drainage, it is possible to promote water drainage in the container 100 and prevent tree root rot by providing a hole in the bottom surface 130.

  A panel guide 142 for inserting and holding the root prevention panel 140 is provided on the side surface of the frame 110. Thereby, the root prevention panel 140 can be attached to and detached from the side wall 120 of the frame 110. In a narrow planting place in the center of the city, the presence of buried objects such as piping near the installation location of the container 100 is predicted. However, by attaching a root prevention panel to the side wall adjacent to the pipe or the like, the side root 120 is prevented from growing in the direction in which the root prevention panel 140 is disposed even after the side wall 120 is biodegraded, and buried in the soil by plants. The influence on the object can be eliminated.

  The root-preventing panel 140 may be any material having a root-preventing property such as a non-biodegradable material. For example, a plastic plate, an iron plate, or the like can be used depending on the required strength. In the first embodiment, the panel guide 142 is integrally formed with the frame 110, but the present invention is not limited to this, and the panel guide 142 may be a separate member. If a separate member is used, the shape of the frame body 110 can be simplified, and if it is formed integrally, the strength of the panel guide 142 can be obtained.

  In addition, a connecting portion 150 for fixing the frame body 110 in a state of being aligned with the other frame body 110 is provided on the side surface of the frame body 110. In the present embodiment, the connecting portion 150 has a structure in which a hole is provided in the protruding plate, and can be connected by bolting in a state where the connecting portions 150 of the adjacent containers 100 are arranged or by being bound with a bind line. it can. With this configuration, when arranging a plurality of frames 110, that is, containers 100, the positions of the containers 100 can be easily aligned and aligned.

  In the first embodiment, the connecting portion 150 is integrally formed with the frame body 110. Thereby, the intensity | strength of the connection part 150 can be improved. Moreover, the connection part 150 can also be made into a member different from the frame 110, Thereby, the connection part 150 can be attached or detached to the frame 110 as needed.

  Furthermore, a support ring attachment 162 as a support ring that is erected by inserting a support can be attached to the side surface of the frame 110. The support ring attachment 162 attached to the frame 110 is in a state where an annular portion that is a support ring protrudes substantially horizontally with respect to the frame 110. Thereby, the support | pillar for supporting the tree 102 can be inserted in this cyclic | annular part, and it becomes possible to fix to the container 100 easily. Therefore, it is possible to prevent a tree that is unstable to stand on its own.

  In the first embodiment, the support ring is a support ring attachment 162 and is a separate member from the frame 110. Thereby, the support ring attachment 162 can be attached to and detached from the frame as necessary. Further, the support ring may be integrally formed with the frame body 110, thereby improving the strength of the support ring.

  FIG. 3 is a diagram illustrating a process from tree production to removal. The tree 102 planted in the planting place is grown and produced in the container 100 at a production facility (not shown) (production process). Then, the tree 102 that has grown to a state where it can be shipped is transported to a planting site by a truck or the like (transportation process). At this time, since the container 100 is a substantially rectangular parallelepiped, space saving can be achieved when the container 100 is loaded on a truck or the like.

  The tree 102 transported to the planting site is planted in the soil together with the container 100 (planting process). The planted tree 102 grows through maintenance such as aeration and irrigation (management process). During the growth of trees in this management process, the side wall 120 of the container 100 is biodegraded and disappears after a predetermined period of time. Therefore, of the roots 102a of the tree 102, the side roots grow in the side wall direction. However, since the bottom surface 130 does not disappear, the growth direction of the straight root is suppressed, and the length of the straight root after the growth is within the height of the container.

  When the grown tree 102 is no longer needed or withered, the tree is removed (removal process). At this time, since the length of the straight root is within the height of the container 100 because the growth direction of the straight root is suppressed in the management process, the height of the container may be excavated during the removal process. Therefore, the labor for excavation during the removal process can be reduced.

  Also, in the above removal process, after excision of the side roots extending outside the frame body, the entire container (frame body) can be removed while the tree 102 is planted. It is also possible to plant the entire container 100 at the relocation site. Therefore, the damage at the time of transfer to the tree 102 which became unnecessary at the planting site can be reduced, the survival rate of the tree 102 at the transfer site can be improved, and the tree 102 after removal can be efficiently reused.

  FIG. 4 is a diagram for explaining the details of the implantation step. Fig.4 (a) is a figure explaining the detail of a planting place. The planting site in FIG. 4A is a strip-shaped (line-shaped) narrow land after removing the block fence 202 that is the exterior of the boundary line of the site. In such a planting site, first, the block fence 202 and its foundation 204 are crushed and the soil is excavated to the height of the container 100.

  Then, the container 100 is buried in the excavated soil. In addition, since the building 200 and the piping 206 are already installed in the planting site, the root prevention panel 140 is attached to the surface of the container 100 adjacent to these. Thereby, the growth of the side root (root 102a) in the surface direction can be suppressed, and the influence on the building 200 and the pipe 206 can be eliminated. Moreover, since the container 100 is a substantially rectangular parallelepiped, space can be used effectively even in a narrow planting land as shown in FIG.

  FIG. 4B is a diagram for explaining a splint to a tree. When attaching a splint to the tree 102, first, the support 208 is inserted into the support ring portion of the support ring attachment 162. Next, the splint 210 is held on the support 208 with a rope or the like. The splint 210 is attached to the splint 210 by restraining the trunk portion of the tree 102. As a result, it is possible to prevent the tree 102 that is unstable to stand upright.

[Second Embodiment]
FIG. 5 is a diagram illustrating a container according to the second embodiment. Fig.5 (a) is an external view of the container concerning 2nd Embodiment, FIG.5 (b) is an external view of the container concerning 2nd Embodiment which attached the accessory. In addition, about the structure substantially equal to 1st Embodiment in 2nd Embodiment, description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  On the side surface of the frame body 110, a support ring 160 for inserting and supporting the support column 208 is provided so as to protrude substantially horizontally. Thereby, the support | pillar for supporting the tree 102 can be inserted in the support | pillar ring 160. FIG. Therefore, it is possible to fix the support 208 to the container 100 and to restrain the splint 210 to the support 208. As a result, it is possible to attach a tree to the tree 102 and to prevent the tree 102 from being tilted. Thus, the strength of the support ring 160 is improved by integrally molding the support ring 160 with the frame 110.

  Furthermore, a connection attachment 152 for fixing the frame 110 in a state of being aligned with the other frame 110 can be attached to the side surface of the frame 110. With this configuration, when the plurality of frames 110 (containers 100) are arranged side by side, the positions of the containers 100 can be easily aligned and aligned. As described above, the connection attachment 152 is a separate member from the frame 110, so that it can be attached and detached as necessary. In addition, the connection attachment 152 may be made of a material different from that of the frame 110.

  FIG. 6 is a diagram for explaining pile driving to a container. FIG. 6 (a) is a container that has been piled, and FIG. 6 (b) is a view in which such a container is buried. As shown in FIG. 6A, a pile 170 can be driven into the support ring 160. As the pile 170, a metal or plastic anchor or the like can be used, and the material can be appropriately changed according to the required strength.

  As shown in FIG. 6B, the container 100 is buried in the excavated soil, and the piles 170 are driven deep into the soil through the support ring 160, thereby preventing the tree 102 integrated with the container 100 from being tilted. . Such pile driving is particularly effective when the root pot weight of the tree 102 is large. Moreover, pile driving can be performed when there is no buried structure or the like at the planting place of the tree 102, and when there is a buried structure or the like, the length of the pile 170 needs to be adjusted. The support ring attachment 162 can also be used for pile driving.

[Other Embodiments]
FIG. 7 is a diagram illustrating a container according to another embodiment. In the embodiments of FIGS. 7A and 7B, the same reference numerals are given to the substantially same configurations as those of the first embodiment and the second embodiment, and the description thereof is omitted. Note that the function of each part is substantially the same as in the first and second embodiments.

  In the container 300 shown in FIG. 7A, metal angle members and plate members are used for the frame 310, the panel guide 142, and the connecting portion 150. Thus, the container 300 configured by combining the metal angle member and the plate member can obtain high rigidity and load resistance. Moreover, although high rigidity can be acquired by comprising by welding, the space concerning transportation and storage before use can be reduced by using an assembly type.

  In the container 300 of FIG. 7A, a frame 310 is provided with a ventilation water passage 220 (aeration pipe). The ventilation water passage 220 is formed of pumice itself. Thereby, the ventilating water pipe 220 can have functions of aeration and irrigation. And by enclosing the ventilation water passage 220 which is a pumice itself with a mesh sheet, it is possible to prevent the soil from entering the voids and small holes of the pumice stone (the ventilation water passage 220).

  With the above configuration, the air and the injected water fed into the ventilation water passage 220 are supplied to the soil 104 in the container. Therefore, aeration and irrigation of the root 102a in the soil 104 can be easily performed. As a result, maintenance labor such as aeration and irrigation can be reduced. Moreover, since water and air are sufficiently supplied to the tree 102 even in a narrow area, the planted tree 102 can be grown well and the management process can be simplified.

  In the container 400 shown in FIG. 7B, the frame 410 has a substantially cylindrical shape. Also with this configuration, the tree 102 can be produced in the container 400, planted together with the container 400, grown while controlling the growth of the straight root and the side root, and the container 400 can be removed. Moreover, since it is a fixed form, space can be reduced during transportation and planting, and it is suitable for planting in narrow land.

  As described above, according to the present invention, the tree 102 produced in the container 100 can be planted in the planting site together with the container 100. And after planting, it is possible to grow in the container 100 buried in the soil and use the container 100 consistently until it is removed. Therefore, the production and transportation efficiency can be improved and the burden on the tree can be reduced.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. However, it goes without saying that the present invention is not limited to such embodiments, and those skilled in the art will be within the scope of the claims. It is obvious that various changes and modifications can be conceived, and it is understood that these also belong to the technical scope of the present invention.
