Description

The present invention relates to a cylindrical container used for rock greening, a method for producing the same, and a method for using the same.

As a method of greening a surface having no or poor soil such as bedrock or concrete, the present inventors have proposed a soilless slope greening method characterized by the following three steps (Patent Document 1). . (1) Planting and curing a plant in a cylindrical container containing a specific water-absorbing resin, a plant-growing carrier and a mixture of water, (2) Soil-free slope (surface without planting soil) And (3) inserting the cylindrical container in which the plant is planted into the hole as it is or inserting the mixture in which the plant is planted into a cylinder. Removing from the container and inserting.
In the method, a cylindrical container for growing plants is used as described above. The cylindrical container is preferably a plastic molded product, and the container may be perforated, but is preferably provided at the bottom. The cylindrical container is filled with a bag to cure the plant and the bag. It is described that it is preferable to put it in the take-out hole.

JP 2012-34648 A

However, since this cylindrical container is made of plastic, its shape does not break after being put into the hole, and it keeps growing roots forever, and the hole opened in the container is small, and the root of the plant is this There is a problem that the roots do not become larger than the hole, and if the bag is inserted, the roots cannot come out of the bag and hinder the growth of plant roots.

An object of the present invention is a bottomed cylindrical container that is made of wood and is embedded in a hole in a rock bed to grow a plant, and when the plant is cured and buried in the rock bed, It is intended to provide a cylindrical container capable of firmly holding a plant growing medium when the root of a plant is not suppressed by suppressing the growth of the plant in the soil and the cylindrical container is transported.

As a result of intensive studies, the present inventors have cultivated plants on the rock mass by forming a plurality of openings on the side surface of the cylindrical container using a thin slice of wood. The inventors have found that this is an advantageous container and have completed the present invention.
The present invention is a bottomed rock planting cylindrical container that is embedded in a rock hole to grow a plant, and the axial side surface of the cylindrical container is formed by combining a plurality of thin sliced timber slices. In the cylindrical container for rock greening having a plurality of openings not covered with the sliced thin plate, the plurality of sliced thin plates of the cylindrical container are wound so as to be inclined with respect to the axis, and the inclination direction is This is a cylindrical container for rock greening that is woven so as to overlap with a plurality of sliced thin plates wound in an opposite direction .

Furthermore, the present invention is characterized in that the total area of the openings is 3 to 40% of the surface area of the side surface.

Furthermore, the present invention is characterized in that a plant is planted in a plant growing medium in which the following water-absorbing resin is mixed in the cylindrical container.
Water-absorbent resin: The water-containing gel has an electric conductivity of 0 to 2.0 mS / cm when 1 part by weight of the water-absorbent resin is absorbed by 100 parts by weight of ion-exchanged water at 25 ° C., and ion-exchanged water at 25 ° C. The water absorption ratio is 80 to 1000 times.

Furthermore, the present invention provides the water-swelling property, wherein the plant-growing medium includes the water-absorbent resin and two or more plant-growing carriers, and at least one plant-growing carrier is an ore-based carrier that develops viscosity with water. It is characterized by being a pellet-like plant growth medium.

Moreover, this invention is a manufacturing method of the said cylindrical container including the following five processes.
Step 1 Winding two sliced thin plates to the opposite sides to create a thin plate set in which both ends are bonded Step 2 Creating a separate ring-shaped thin plate 3 Combining the plurality of thin plate sets, one end of the ring shape Step 4 for creating a pre-container-1 fixed with a thin plate Step 5 for creating a pre-container-2 having both ends fixed with ring-shaped thin plates by combining the plurality of thin plate sets.

Further, the present invention provides a plant growing medium containing water and a water-absorbing resin mixed with the above-mentioned cylindrical container, and the plant is grown and cured, and after the curing, the cylindrical container is taken out and formed on the bedrock. This is a method of using a cylindrical container for rocky greening, in which a cylindrical container in which the plant is planted is inserted and fixed as it is.

According to the present invention, since the cylindrical container has a plurality of openings that are not covered with the sliced thin plate on the side surface in the axial direction, the root of the plant opens the opening when the plant is cured and after being embedded in the rock. It passes through the outside of the cylindrical container and can fully extend the roots, and does not inhibit plant growth. In addition, since the side surface of the cylindrical container is formed of a thin sliced plate of wood, the shape retention of the cylinder is improved, and the shape of the cylinder can be held firmly even if a plant growing medium is put inside. Does not collapse during transportation.
In addition, since wood is used, the cylinder is naturally decomposed, and the container frame does not remain in the place where the cylindrical container is buried. In addition, it can be used for thinned wood and waste wood as well as ordinary wood, so there is an advantage that a cylindrical container can be made at low cost.

According to the present invention, the plurality of sliced thin plates of the cylindrical container are wound so as to be inclined with respect to the axis, and overlap with another plurality of sliced thin plates wound in a direction opposite to the inclined direction. Therefore, the plurality of openings can be easily and uniformly formed, and the shape retaining property of the container is further improved, and the container is not broken when transported after planting a plant in a cylindrical container.
According to the present invention, since the total area of the respective areas of the openings is 3 to 40% of the surface area of the side surface, the roots of the plant can be easily extended out of the container, thereby inhibiting the growth of the roots. do not do.

According to the present invention, since a water-absorbing resin suitable for plant growth is used as a water retention improver in the plant growth medium, if the water is supplied first, the plant will die even if water is not used for a long time. There is nothing.
According to the present invention, the plant growth medium includes the water-absorbing resin and two or more plant growth carriers, and at least one plant growth carrier is an ore-based carrier that develops viscosity with water. Therefore, when the water is supplied, the viscosity of the plant growing medium increases, and the plant growing medium is less likely to leak from the opening of the cylindrical container.

According to the method for manufacturing a cylindrical container of the present invention, since a plurality of thin plate sets are combined and both ends are fixed with ring-shaped thin plates, a cylindrical container can be easily and efficiently created, and a more uniform opening Since the part can be formed, the root growth of the plant planted in the cylindrical container is not inhibited.

  According to the method for greening the rock mass using the cylindrical container of the present invention, the planted plant can sufficiently root and extend firmly to the rock mass outside the cylindrical container.

  Hereinafter, embodiments of the present invention will be described in detail. Note that the present invention is not limited to the following embodiments. Various modifications can be made to the following embodiments within the same and equivalent scope as the present invention.

In the cylindrical container of the present invention, the axial side surface of the container is formed by combining a plurality of thin sliced wood thin plates, and has a plurality of openings that are not covered with the sliced thin plates. The combination of the plurality of sliced thin plates is not particularly limited as long as a plurality of openings are formed when the side surfaces are formed. For example, a plurality of sliced thin plates of wood are formed to extend parallel to the axis of the cylindrical container, and the middle is wound or joined with a thin plate or other material, the skeleton on the side of the container is It may be made of a rod and a plurality of sliced thin plates are seeded on the outside thereof.

A preferred combination of sliced sheets is that a cylindrical container is wound so that the plurality of sliced sheets are inclined with respect to the axis, and another plurality of slices wound in a direction opposite to the inclined direction. It is formed so as to be woven over a thin plate. In this way, the sliced thin plates can be stacked alternately or resembling a lattice, and the opening has a rhombus shape, a similar shape or a rectangular shape, and a shape and size similar to each other can be easily obtained. (It is said to be uniform in the present invention), the root of the plant is easy to extend through the opening, and it is difficult to inhibit the growth of the plant. There is also an advantage that it can be easily extended to the bottom of the cylinder.

FIG. 1 shows a perspective view of a cylindrical container according to an embodiment of the present invention.
“Ring-like thin plate” 2 is formed at both ends of the cylindrical container 1, and an elongated slice thin plate 3 extends from one ring-like thin plate 2 so as to be inclined with respect to the axial direction. It is formed so as to overlap with another sliced thin plate 3 which is inclined and wound in a direction opposite to the inclined direction, and is connected to the other ring-shaped thin plate 2. The part 5 where the two sliced thin plates overlap is just on the opposite side of the first joining part 6. Also. A portion (opening) 7 formed by intersecting the sliced thin plates 3 and not covered with the thin plate has an elongated rhombus shape and is present substantially uniformly on the entire side surface of the cylinder. The cylindrical container 1 formed in this manner has good shape retention even when a plant-growing medium is placed therein, and the opening 7 is relatively wide so that the roots of the plants can pass freely. This ring-shaped thin plate is sometimes referred to as a “ring”.

The sliced sheet of wood used in the present invention is obtained by cutting wood. Although a width | variety, thickness, and length will not be limited if a cylindrical container can be created, 10-30 mm in width and 0.8-1.5 mm in thickness are preferable, and 20-25 mm in width and 1.2 mm in thickness are more preferable. The length is arbitrary. When the container has a width of 10 to 30 mm, a plurality of openings can be easily formed and the shape retainability is good. When the thickness is 0.8 to 1.5 mm, the thin plate can be easily formed without breaking, and the shape retainability is good, and the shape can be retained even if a plant growth medium is placed therein.

The material of the wood slice thin plate is not particularly limited, but soft wood such as pine, cedar, firewood and poplar is preferably used. Further, the sliced thin plate of wood may be used as it is, but a material having high flexibility is preferable because it is wound when the cylindrical container is formed. For example, by immersing in boiling water, steaming in high-temperature steam, or passing through the steam of a high-temperature steam generator, high-temperature humidification suitable for the use of wood is performed to provide flexibility. Preferably, it is immersed in boiling water for about 1 hour. By doing in this way, a softness | flexibility can be provided to the sliced thin board of wood, and when forming in a cylindrical container, a sliced thin board can be wound hard to be broken.
Further, the portion that becomes the “ring-shaped thin plate” is preferably wood, and it is more preferable to use the sliced thin plate used for the above-mentioned side surface because of flexibility.
The sliced thin plate may be a single plate or a laminate of two or more, but a single plate is preferable from the viewpoint of flexibility.

Although a cylindrical container can be created in the following five processes, it is not limited to this.
1. Production of a thin plate set in which two sliced thin plates are wound around opposite sides and bonded at both ends thereof. FIG. 2 shows a perspective view when the thin plate set 4 is produced using a mandrel 8. 2A shows a perspective view when two thin plates are wound around a mandrel, FIG. 2B shows a perspective view of a thin plate set removed from the mandrel, and FIG. 2C shows a side view of the mandrel. It is a side view of the thin plate set seen from.
A metal cylindrical mandrel 8 (for example, outer diameter 4 cm, length 40 cm) and two sliced sheets 3 of the same length are prepared, and the ends of the two sliced sheets 3 are attached to one end of the mandrel 8. Overlapping (overlapping portion 6), one slice thin plate 3 is wound so as to incline to the axis of the mandrel 8, and another slice thin plate 3 is wound in an opposite direction, and the first overlapped portion is 180 degrees. Two sliced thin plates 3 are put together on the opposite side opposite to each other (overlapping portion 5), and both ends are bonded together (hereinafter referred to as “thin plate set”) 4), removed from the mandrel 8. Four such thin plate sets 4 are created.
From FIG. 2 (c), it can be seen that the two sliced thin plates 3 are wound so as to draw a circle when viewed from the side and are bonded at both ends.

2. Creation of Ring-shaped Thin Plate FIG. 3 shows a side view of the ring-shaped thin plate 2 and the mandrel 9 created.
A cylindrical cylindrical mandrel 9 (for example, an outer diameter of 5 cm and a length of 50 cm) slightly larger than the mandrel 8 used in the above 1 is set vertically, and a single sliced thin plate 3 is wound around the lower end of the mandrel 9 A thin plate 2 is prepared and fixed with an adhesive. Cut the excess slices. In this case, the bonded portion may be pressed and bonded, but it is preferable to use an instantaneous adhesive because it can be bonded quickly in time.

3. Preparation of pre-container-1 in which a plurality of thin plate sets are combined and one end is fixed by a ring-shaped thin plate 2 FIG. 4 is a perspective view when a plurality of thin plate sets 4 are combined and one end is fixed by a ring-shaped thin plate 2 showed that. Four thin plate sets 4 are evenly arranged around the mandrel 9 on the ring-shaped thin plate 2, one end of one thin plate set 4 is bonded to the ring-shaped thin plate 2, and the remaining thin plate sets 4 are arranged in order. The four thin plate sets 4 are fixed by attaching them around the mandrel 9. Further, a ring-shaped thin plate 2 is formed from the sliced thin plate 3 from above, and four thin plate sets 4 are fixed to prepare a pre-container-1. This is removed from the mandrel 9.

4). Preparation of Pre-container-2 Combining Multiple Thin Plate Sets and Fixing Both Ends with Ring-shaped Thin Plates FIG. 5 shows a perspective view when combining multiple thin plate sets 4 and fixing both ends with ring-shaped thin plates 2.
The ring-shaped thin plate 2 is prepared at the lower end of the mandrel 9 in the same manner as 2 above, and the ends of the four thin plate sets 4 are reversed by reversing the pre-container-1 removed at 3 on the ring-shaped thin plate 2. Glue. Further, the ring-shaped thin plate 2 is prepared in the same manner as 3 above, and the four thin plate sets 4 are fixed to prepare the pre-container-2.

5. Creation of Container Bottom FIG. 6 shows a perspective view of a cylindrical container with a bottom according to one embodiment.
Remove the pre-container-2 from the mandrel 9 and attach the bottom to one end. If the plant growing medium does not fall, the bottom may or may not have a hole in the bottom, and is not particularly limited, and may be a plate, rod, or a combination thereof. In FIG. 6, a hole 10 is made in the opposite surface of the ring-shaped thin plate 2, and a thin wooden stick 11 is attached so as not to fall, and three of them are attached equally. It is only necessary that the plant-growing medium is difficult to drop from that location. In this way, a bottomed cylindrical container composed of the four thin plate sets 4 having both ends fixed by the ring-shaped thin plate 2 is completed.

The size of the cylindrical container thus prepared is not particularly limited. For example, the diameter is preferably 40 to 75 mm in outer diameter and 45 to 65 mm in inner diameter. The length is preferably 25 to 50 cm. These are preferably determined according to the type of plant to be planted, the state when the plant grows, the condition of the rock mass, and the like.

A plurality of openings may be provided, but the number is preferably 5 to 30. When the number is 5 or more, many roots of the plant come out of the cylindrical container and can be firmly rooted. When the number is 30 or less, one opening is not too small, and the root that has passed through the opening can be enlarged.
The size of one opening is preferably 1 to 10 cm ² . If it is 1 cm ² or more, the root passing through the opening becomes large, and if it is 10 cm ² or less, the plant-growing medium is less likely to spill from the opening. Moreover, it is preferable that the sum total of the area of an opening part occupies 3-40% of the surface area of a side surface, and it is more preferable to occupy 5-30%. If it is 3% or more, the root of the plant can easily pass through the opening from the viewpoint of the entire cylindrical container, and if it is 40% or less, the plant-growing medium is difficult to leak from the opening, and the shape retention of the cylindrical container is good. .

The shape of the cylindrical container is preferably cylindrical from the manufacturing surface. The size (diameter) of the container is not limited as long as a plant is planted, but 40 to 100 mm is preferable, and 50 to 70 mm is particularly preferable. A plant can be sufficiently planted as it is 40-100 mm, and it is easy to embed a cylindrical container in a bedrock. When a rock drill is used to make a hole of 50 to 70 mm, the size of the hole formed by the rock drill is about 75 cm, so that it is easier to put in the hole and the plant after transplanting is fixed. Easy to be. The length of the cylindrical container is shorter than the depth of the hole, and there is no limitation as long as the plant is rooted in the container, but it may be about half the depth of the hole, for example, 20 to 60 cm, and 20 to 40 cm is compact. This is particularly preferable.

In the present invention, a plant growing medium for growing a plant is placed in the cylindrical container, and the plant growing medium is obtained by adding water to a plant growing carrier.
The plant growth carrier is not particularly limited as long as it is generally used as a substance suitable for plant growth. For example, water-insoluble solid materials such as powders such as inorganic substances and / or organic substances, porous bodies, pellets, fibers and foams can be used. As inorganic substances, inorganic powders (soil, sand, fly ash, diatomaceous earth, clay, talc, kaolin, bentonite, dolomite, calcium carbonate, alumina, etc.); inorganic fibers (rock wool, glass fibers, etc.); inorganic porous materials [ Filton (porous ceramic, kuntan), vermiculite, pumice, volcanic ash, zeolite, shirasu balloon, etc.]; inorganic foam (perlite, etc.).

Organic substances include organic powders (boiled wood, wood waste, wood flour, etc.), organic fibers [natural fibers (cellulosic (eg sawdust, straw), etc.), grass charcoal, wool, etc., artificial fibers (rayon, acetate, etc.), synthetic Fiber (polyamide, acrylic, etc.), pulp [mechanical pulp (such as crushed wood pulp from logs), chemical pulp (such as sulfite pulp, soda pulp, sulfate pulp, etc.), semi-chemical pulp, recycled pulp, etc., other waste materials (paper diapers) Etc.], organic porous materials (coconut shell activated carbon, etc.), organic foams (cereals, synthetic resins or rubber foams (polystyrene foam, rubber sponges, etc.)), organic pellets [rubber and Synthetic resin pellets, etc.]. The above plant-growing carriers may be used alone or in combination of two or more as required. Among these, preferred are inorganic powder having water absorbency, inorganic porous material, inorganic foam, and organic fiber, and more preferred is soil. Further, it is particularly preferable to use a mixture of soil and a plant-growing carrier having water absorption other than soil.

It is preferable that a water-absorbing resin is further mixed into the plant growth carrier to improve water retention. The water-absorbent resin absorbs water and becomes a hydrous gel.
The water-absorbent resin has a water-containing gel electrical conductivity of 0 to 2.0 mS / cm when 1 part by weight of the water-absorbent resin is absorbed by 100 parts by weight of ion-exchanged water at 25 ° C., and ion exchange at 25 ° C. There is no particular limitation as long as the water absorption ratio is 80 to 1000 times. Since this water-absorbent resin does not inhibit the growth of plant roots, it can be well rooted even if the plant is cured in a cylindrical container, and it can withstand even if it does not rain for a long time after curing or after shifting to the bedrock. Grow plants without. The above numerical range of the water-absorbent resin is in accordance with the description in JP-A-2007-319029.

Such a water-absorbing resin is a nonionic water-soluble ethylenically unsaturated monomer (A) such as hydroxyethyl (meth) acrylate (A) alone, an anionic water-soluble such as (meth) acrylic acid. Polymer (Y) consisting of a water-soluble ethylenically unsaturated monomer (C) alone, and a nonionic water-soluble ethylenically unsaturated monomer (A) and an anionic water-soluble ethylenically unsaturated monomer (B) It consists of the copolymer (Z) which has as a structural unit. It is possible to use only (X), (Y), (Z), and it is also possible to use a mixture of two or more of (X), (Y), (Z). Of these, the water-absorbent resin composed of the anionic polymer (Y) or (Z) does not particularly inhibit the growth of plant roots, so that it can be well rooted even when plants are cured in a cylindrical container. In addition, the plant will not wither even if it is transplanted to bedrock and it does not rain for a long time.
As the water absorbent resin applied to the present invention, those described in JP-A-2007-319029 can be suitably used.

When mixing the plant-growing carrier and the water-absorbent resin, they may be mixed in a cylindrical container, but it is preferable to mix them in a separate container and then put them into a uniform container. These may be mixed at the same time, but after mixing the water-absorbing resin and water to create a water-containing gel, the plant-growing carrier is added and mixed so that the water-absorbing resin is uniformly water-containing gel. This is preferable.
In addition, the method of mixing water from the top after mixing the plant-growing carrier and the water-absorbing resin first and putting the mixed powder in a cylindrical container is efficient and efficient. In this case, it is preferable to put powder mixed in about the seventh to eighth minutes of the length of the cylindrical container.

The ratio of the water-absorbent resin to water varies depending on the water-absorption capacity of the water-absorbent resin and the type of plant, but is preferably 1:10 to 1: 1000, more preferably 1:20 to 1: 500 by weight ratio. . If it is 1:10 to 1: 1000, a plant can come out of a rooted opening in a cylindrical container, and the plant will not wither for a long time even after transplanting the plant to the rock.

The ratio of the plant-growing carrier and the water-absorbing resin is not particularly limited, but the water-absorbing resin is preferably 0.5 to 10% by weight with respect to the weight of the plant-growing carrier. If it is 0.5% by weight or more, water can be supplied so that the roots of the plant do not die, and if it is 10% by weight or less, the water-absorbing resin contains a large amount of water and swells, making it difficult to fix the plant. There is no. Most preferably, it is 0.2 to 5 weight%. Within this range, the plant can be sufficiently supplied with water while being more firmly fixed.

Moreover, as a mixture of said plant growth support | carrier and a water absorbing resin, a pellet-shaped thing is easy and easy to use. The pellet is not limited as long as it contains the above water-absorbing resin and a plant-growing carrier, and includes two or more inorganic plant-growing carriers, and at least one plant-growing carrier is water. Particularly preferred is a water-swellable pellet which is an ore-based carrier that develops viscosity.
“Two types” refers to a mixture of different types of plant growth carriers, for example, one ore carrier and another inorganic carrier, one ore carrier and another kind of ore carrier, etc. . "Two or more types" means that other inorganic plant growing carriers are included in addition to these. The expression of viscosity by water refers to a state where the adhesiveness can be clearly confirmed when touched with the hand when the surface of the carrier is wetted with water. When at least one inorganic plant-growing carrier develops viscosity with water, the carriers are easily bonded together in a wet state, and a water-absorbent resin is also bonded, so that a good pellet can be prepared by drying. A carrier other than the ore-based carrier that develops viscosity by water may or may not be viscous, but is preferably the main base for plant growth.

Examples of ore-based simple substances that develop viscosity by water include hydrous aluminum silicate clay minerals such as sericite, pyrophyllite, galeonite, smectite, montmorillonite, kaolinite, bentonite, and phyllosilicates such as sepiolite. Can be mentioned.

The pellets obtained by kneading and drying the water-absorbing resin and the above-mentioned plant-growing carrier have the carrier powder intrude into the water-absorbing resin particles or vice versa. It is more uniform. Therefore, the plant is in a state that is easy to absorb water and nutrients at the same time, that is, a so-called advantageous state for the growth of the plant, as compared with a simple mixture of water-absorbing resin particles in the soil. Compared to the case where the water-absorbent resin is simply blended in the soil, or the case where only the water-absorbent resin water-based gel is used, it is considered advantageous for the growth of the plant and the growth of the plant is promoted. In addition, the carrier and the water-absorbent resin are more uniform and integrated in detail, and even if the pellets are firm, the water-absorbent resin can absorb water and swell and quickly disintegrate to become a plant growing medium. As such pellets, water-swellable pellets for plant growth described in JP 2012-080788 A and JP 2012-080785 A can be preferably used.

The above mixture and pellet may contain components known in the art such as fertilizers, plant growth hormones, antibacterial agents, trace elements, and fungicides. The fertilizer may be a natural fertilizer or a chemical fertilizer, and either a fast-acting fertilizer or a slow-acting fertilizer can be used.

In the cylindrical container of the present invention, the plant is grown and planted in a plant-growing medium containing the water-absorbing resin mixed with the water-absorbing resin, taken out after curing, and the plant is placed in a hole formed in the bedrock. The planted cylindrical container is inserted and fixed as it is. As a method for using the cylindrical container, a method described in JP 2012-34648 A can be suitably applied. In the present invention, the term “bedrock” includes a place where plants such as hard soil and concrete are difficult to grow in addition to a normal bedrock.
After putting said mixture or pellet in a cylindrical container, a seedling is planted and cured. The curing period varies depending on the plant, but is preferably about one week to several months. The curing conditions vary depending on the plant, but normal curing conditions can be applied. When curing, it may be cured only with a cylindrical container, but it is preferable to dig a hole in the soil and grow it by adapting to the soil, since it will firmly root. During this time, the roots of the plants come out from the opening of the cylindrical container and extend to the external soil, so that the growth can be accelerated. In addition, after curing, the tubular container is pulled out together with the plant and transported to the place where it is greened. At this time, the plant-growing medium rarely leaks from the opening of the tubular container.

Aside from the curing, a hole for a cylindrical container containing plants in the bedrock is formed. The shape of the hole is not particularly limited, but a cylindrical shape is preferable. The size of the hole is not limited, but 40 mm to 150 mm is preferable from the viewpoint of construction work. In particular, when drilling holes using a rock drill, a size of 60 mm to 80 mm is preferable. When using a rock drill, a hole with a width of about 75 cm is usually formed. When the bedrock is a slope, the hole is preferably drilled so that the center line in the depth direction of the container is 30 ° to 90 ° with respect to the horizontal direction. Although the depth of a hole is not limited, 40 cm-1 m are preferable on construction work, and 50-70 cm is more preferable.

When inserting a cylindrical container etc. into a hole, a cylindrical container can be inserted as it is. It is preferable to put about half of the above mixture or pellet first, then add water, and then insert a cylindrical container. Make sure that the inlet of the inserted cylindrical container is at the same level as or slightly higher than the surface of the rock mass. At this time, mix the mixture or pellet so that the gap between the cylindrical container and the rock mass fills the gap. It is preferable to add. Thus, a cylindrical container etc. can be fixed to a hole and a seedling is fixed to a bedrock.

As the plant grows, the root is rooted in an external plant-growing medium through the opening of the cylindrical container. This allows the plant to take root in the bedrock. In addition, if there is a crack in the bedrock, the root enters the crack and integrates with the bedrock. After the plant is planted, it can live only in the cylindrical container, but it is preferable to have a plant-growing medium in which the plant can grow in the same way outside the cylindrical container because there is a root force.

Although there is no limitation in particular as a plant for putting in the cylindrical container of this invention and planting green, a seedling is preferable. As seedlings, seedlings of various types of trees that are normally used for rock planting can be used without any particular restrictions, but usually plants and landscapes that are suitable for the vegetation around the land in accordance with the rock planting target. There is no limitation to select and use plants useful for formation. For example, Sudajii, Tsuburajii, Arakashi, Vulcania serrata, Shirakashi, Shiragashi, Tabonoki, Yabunikei, Shirodamo, Yabutsubaki, Mochinoki, Hisakaki, Aoki, Beech, Mizunara, Hauchiwakaede, Yamamemi, Azalea, Azalea , Harunire, Sawagurumi, Katsura, Fir, Tsuga, Pinus, Kuromoji, Witch Hazel, Aoki, Yabuteki, Yuzuriha, Insect, Yamashikimi, Rhododendron, Periwinkle, Maple, Ginseng, Oak, etc. can be selected. Of these, Pinus genus and the like are preferably used.

Set a metal cylindrical mandrel (outer diameter 5 cm, length 50 cm) different from the above vertically, wind one slice thin plate around the end of the mandrel, create an attached ring thin plate, and use adhesive Fixed. Excess slices were cut.
Place four sheet sets evenly around the mandrel on the ring sheet, glue one end of the sheet set to the ring sheet, and wrap the remaining sheet sets around the mandrel in order. It attached so that it might turn, and the four thin plate set was fixed. Further, a ring-like thin plate was made from the sliced thin plate from above, and a pre-container 1 in which four thin plate sets were fixed was produced. This was removed from the mandrel.

A ring-shaped thin plate is prepared at the lower end of the vertical mandrel, and the ends of the four thin plate sets are bonded to each other with the pre-container 1 removed on the ring-shaped thin plate reversed. Further, a ring-shaped thin plate was prepared in the same manner as described above, and a set of four thin plates was fixed to prepare a pre-container 2.
For the method of attaching the bottom to one of the cylinders, a hole is made in the opposite face of one ring-shaped thin plate, and a thin wooden rod with a width of 2 mm and a length of 60 mm is inserted so as not to fall, and three of these are evenly placed. The bottomed cylindrical container of the present invention was prepared. The cylindrical container inner diameter 5 cm, an outer diameter of 6 cm, a cylindrical length 30 cm, there aperture 15 places (pieces), occupies the area of the side surface of the total area of the opening (60cm ²⁾ (565cm ²⁾ The ratio (ratio) was 10.6%, and the area per opening was 4 cm ² / piece.

(Production Example 1) Production of water-swellable pellet-like plant growing medium 60 parts by weight of vermiculite (pulverized commercially available vermiculite to 2000 μm or less), “PANGELB 40” (Sepiolite, manufactured by Enomoto Kasei Co., Ltd., bulk density 200 g / L) 30 weights 10 parts by weight of water-absorbing resin (cross-linked polyacrylate type, water absorption magnification 230 g / g, electric conductivity 1.7 mS / cm, weight average particle diameter 200 μm, water absorption speed 350 seconds) and mixed uniformly Is added to 200 parts by weight of 1.5% by weight aqueous solution of “DF-17” (carbonyl group-containing polyvinyl alcohol, manufactured by Nippon Vinegar Bipovar Co., Ltd.) and kneaded with a disk pelleter type molding machine. After being molded into a solid, it was dried by heating at a temperature of 120 to 130 ° C. to obtain a pellet having a density of 0.65 g / cm ³ . Although the pellet was strongly pressed by hand, the shape did not collapse and the shape retention was good. Moreover, when 15 times as much water was added to this pellet, it swelled and disintegrated.

(Example 2) Usage method of cylindrical container In the cylindrical container prepared above, the pellets manufactured above were put up to the seventh to eighth minutes of the length of the cylindrical container. After planting a pine seedling there, 150 g of water was added to absorb water. Similarly, 15 of these were prepared. This was dug into the soil and buried for 3 months. After curing, 11 of them were taken out together with the cylindrical container. When this cylindrical container was taken out, it was confirmed that many roots emerged from the opening and that it was well rooted.

A total of 11 holes with a diameter of 64 mm and a depth of 50 mm were drilled on the slope of the bedrock with a rock drilling machine with 6 holes in the first stage, 5 holes in the second stage, and 2 m intervals. About half of the above-mentioned pellets were put in each of the holes, and water was added from above to the same ratio as in curing, and then a cylindrical container containing pine seedlings was inserted into the holes. Although it was observed after 2 weeks in this state in which the mixture of the above pellets and water was fixed in the gap, it was not withered. There has been no rain for the last two weeks. Furthermore, it was observed 6 months later, but all 11 were growing large without dying. It was clear that the trunk was turning upwards. When one of them was extracted and the roots were observed, it was confirmed that the roots were stretched and entered into the rock crevice. It turned out that the cylindrical container of this invention is effective in the greening of a rock mass.
