DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling pot for plants, and more particularly to the structure of a seedling raising pot intended for revegetation in desolate rough lands where weeds remain or in a severe natural environment where desertification is progressing.

[0002]

2. Description of the Related Art Attempts have been made to cultivate suitable plants that are compatible with the land in the natural environment. However, the environmental conditions of the land where restoration of nature is planned are usually severe, It is difficult to plant it on the ground as it is. This is because various conditions surrounding the seeds and seedlings, such as herbaceous roots remaining in the surroundings, competing plants, wind, temperature, humidity, rain and snow, are not always the only conditions suitable for the plants.

For this reason, various means for protecting the growth of seedlings have been proposed. For example, Tokuho 6-5
No. 6020 discloses placing concrete blocks dusted with plant seeds or concrete blocks planted with plant seedlings on slopes or the like.

Japanese Unexamined Patent Publication No. 9-3937 discloses a seedling pot formed of a concrete block. Since this type has a sand layer on the surface, it has an advantage that it has moisturizing properties even in a severe environment, and that moss can be grown.

[0005]

[Problems to be Solved by the Invention] By the way, Japanese Patent Publication 6-5
The technique disclosed in Japanese Patent No. 6020 is an aesthetic preservation technique for breeding plants on sloped concrete that also serves as soil retention, and proposes a special environment in which the surroundings of plants to be grown are covered with concrete. Although growing plants on a slope is good, it is different from the object of the present invention in that plants are grown in an area to be hardened with concrete. The present invention aims at restoring natural vegetation as much as possible in a desolate rough sloping land where weeds remain or in a dry environment where desertification is progressing. Not a suggestion.

On the other hand, the concrete block disclosed in Japanese Patent Application Laid-Open No. 9-3937 is excellent in protecting plant growth in a natural environment, such as maintaining a certain level of moisture retention. However, the use of concrete blocks for raising seedlings cannot deny the following difficulties.

First, it is difficult to handle blocks. When trying to improve the natural conditions of rough land, the land is often remote from the settlement, but the difficulty is that molded block products must be transported by truck or other means of transport from the city or settlement where the goods are collected. Remains. At this time, if the molded article of the concrete block is to be transported as it is, there is a concern that a great obstacle may occur in terms of the transportation capacity and cost of the vehicle. Unlike construction work and civil engineering in a limited area, transportation efficiency and cost can be a fatal obstacle when dealing with a large area with a limited budget.

[0008] Second, there are the problems of the molding cost and the construction period of the block. Concrete blocks, no matter how simple, take the steps of making a formwork, pouring cement and curing. Naturally, it takes a certain amount of time from ordering to delivery, and the cost of forming a mold increases. Therefore, the speed of vegetation business using concrete blocks is hindered, and the cost per container is high. Therefore, various inconveniences arise, for example, such as urgent protection of vegetation on a large land due to a budget, or the inability to promptly respond to obtaining on-site guidance of an expert within a short time due to a schedule. The restoration of nature by raising seeds and seedlings is a matter that should be considered based on the complex correlation of natural anthropogenic factors, and there is a situation in which there are not many human resources who can provide accurate guidance.

Third, there is a problem of maintaining the shape of the block. Seedling blocks are generally placed on the ground and laid with soil around them. However, if the concrete is weak, the blocks will collapse due to the vegetative growth of the plants, and the intended purpose cannot be achieved. For this reason, it is necessary to increase the block strength to some extent so that it does not lose its shape due to wind and rain. However, increasing the concrete strength may leave the blocks in their original shape even after the plants have grown, which in turn may hinder plant growth. Even if the concrete is prepared so that the blocks will collapse due to the growth of the plant, the block fragments that have been agglomerated will remain on the land and cause various problems.

Fourth, there is the problem of freedom of modeling. In the conventional block, it is difficult to prepare various shape types in advance because the molding cost increases. On the other hand, even in the case of recovering and maintaining natural vegetation, in places that are noticeable, such as river parks, there are times when it is desired to systematically promote plant placement after growth in order to improve aesthetics. In such a case, the arrangement and combination of conventional blocks are limited, and it is difficult to design freely. In addition, when the blocks are adjacent to each other, it is difficult for the blocks to collapse due to the growth of the plant, and there is a problem that the concrete remains indefinitely in the portion where the seeds are placed.

It is an object of the present invention to provide a seedling growing pot which is a block which can be reduced to natural soil, can guarantee the freedom of molding, is low in cost, and is easy to handle.

[0012]

In order to achieve the above object, a seed and breeding pot according to the present invention is formed by folding a thick paper panel which is reducible to soil and which can be folded. The double container has an outer container and an inner container on the side surface and the bottom surface, respectively, and has a fixed clearance between the outer container and the inner container. While leaving it open,
The central part of the container, which is the part inside the inner container, has no bottom and no lid, and the gap between the side surface and the bottom surface constituting the double container can be filled with soil reducible soil material for maintaining the container shape for a certain period of time. Provide space. It is desirable to use cardboard as the paper panel.

[0013]

The seedling raising pot according to the present invention uses a foldable paper panel (for example, cardboard) to form a double container having a fixed gap on the side wall and the bottom surface. This doubled part has no bottomed lid so that it can be filled with coarse concrete or soil.

On the other hand, the central portion from the inner side wall is bottomless, that is, hollow. Therefore, the overall shape of the pot is substantially cylindrical, and when viewed in plan, the side wall portion is doubled, and the double portion has a bottom surface and no lid.

When seedlings are planted, appropriate soil and grain materials, for example, cement and coarse aggregates blended so as to be easily weathered, and soil and sand that match the natural conditions of the land are placed in the double part of the pot, whereby Stabilize the shape. Next, soil and seedlings are put in the central portion of the pot, that is, the hollow portion, and the pot is lightly buried in the soil. The soil to be put into the central hollow portion may be mixed with an appropriate root-feeding agent such as an activator of soil microorganisms, a fertilizer, or charcoal powder, if necessary.

Since the seedling raising pot is formed by folding a paper panel, its plane shape is, for example, substantially triangular, substantially square,
It has a polygonal shape such as a substantially pentagon, a substantially hexagon, and a substantially octagon.
By combining these bent-shaped polygonal pots, it is structurally strong, and it is possible to relatively freely create a vegetation design of an arbitrary shape.

In this seedling growing pot, a double container made by folding a paper panel is filled with cement or a suitable soil material which is easily mixed and weathered to maintain its shape. In places with lots of water such as near rivers and wetlands, it is desirable to load cement to maintain the shape of the container,
Even in this case, the cement mixing ratio can be significantly reduced,
After the plants have grown, the cement (concrete) easily weathers and returns to the soil. Of course, the paper panel forming the outer shape of the container also weathers and returns to the soil.

The advantage of this pot is that the double side wall and bottom can be filled with soil and sand that match the natural conditions of the land. For example, in a dry area, the shape can be maintained without using concrete, and a container can be easily made using the soil, stone, or sand of the land. Of course, these loadings will return to earth after supporting plant growth.

[0019]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 7 show an example of a seedling raising pot according to the present invention. As shown in the figure, this seedling raising pot 11 is formed by folding a corrugated cardboard punched into a predetermined shape and forming a double-sided container structure having a substantially hexagonal shape in a plane, and includes an outer container (12) and an inner container (13). The sandwiched double portion 21 has an open top surface without a lid so as to allow the soil to be filled with reducible soil particles, and has bottom surfaces 14a to 14f. On the other hand, the central portion 22 of the inner container is hollow without a bottom and a lid so that seeds and soil can be put therein.

FIG. 3 shows the pot 11 in an unfolded state. In the figure, corresponding parts are denoted by the same reference numerals as in FIGS. 1 and 2. That is, the panel portion 12a
Reference numerals 1 to 12f denote portions to be the side walls of the outer container.
Reference numerals 3a to 13f denote portions serving as side walls of the inner container, and reference numerals 14a to 14f denote portions serving as bottom surfaces of the double portion 21. Also, the side wall 13 is formed so as to form the inner container (13).
A cut 18 is made between a to 13f, and each bottom surface 14a to
A triangular cut 19 is provided between 14f.

Reference numeral 15 denotes an overlapping portion of the inner container.
Further, slits 17 and inserts 16 that can be fitted into the slits 17 are provided at both ends of the panel portion forming the outer container so that they can be locked so as to maintain the folded container shape. Further, it is desirable to apply a ruled line processing (shown by a broken line in the figure) to facilitate assembly at each bending position.

The seedling growing pot 11 is formed by bending a paper panel 11a from which an appropriate material (for example, cardboard) is cut out at a predetermined ruled line position (a broken line position in FIG. 3), and inserting an insertion 16 into a slit 17 to form an outer wall. Engage and assemble.

Then, as shown in FIG. 4, soil particles 25 reducible to the soil are procured, for example, at the site, filled in the double part 21, and seeds 31 and soil 30 are loaded in the central part 22. The greening is performed by placing the pot 11 on the ground G and applying the soil 50 to an appropriate height as shown in FIG. As the soil particles to be filled in the double portion 21, for example, cement or coarse aggregate blended so as to be easily weathered, or soil or sand that matches the natural conditions of the land is used. still,
6 and 7 show examples of the arrangement of the pots.

Further, the panel 11a can be easily and inexpensively manufactured by punching out corrugated cardboard, and there is no need for a mold as in the case of molding a concrete block. In addition, since the paper is transported to the site without assembling it into the final container and transporting it in a state in which the paper panel is unfolded, it is not bulky, has a lighter weight than a concrete block, and is extremely easy to handle.

Further, the pot has panel portions (12a to 12f, 13a to 13f in FIG. 3) forming inner and outer side walls.
By changing the number of arrangements and the shape (angle) of the notch on the bottom (FIG. 19) as required, it is possible to assemble various polygonal pots such as substantially pentagonal and octagonal planes in exactly the same manner. Can be done.

Therefore, for example, a pentagonal pot and a hexagonal pot are used in combination, and the pots are arranged close to each other so that the hexagonal pot surrounds the pentagonal pot like a soccer ball skinning pattern. For example, it is possible to perform various plant arrangements such as covering a spherical land (a hemispherical hill or the like) without gaps.

[0027]

As described above, according to the present invention, it is possible to reduce to natural soil and to have freedom of molding.
Moreover, a seedling raising pot that can be easily handled at low cost can be provided.
