Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a plant growing block used for growing a plant such as a lawn on a roof of a concrete building or a concrete paved surface.

[Conventional technology]

When a concrete building or the like is used in an exposed state, it is strongly influenced by an artificial feeling, and it is not possible to give comfort to the person who sees it. Therefore, recently, artificial grass is placed on the surface of such a rooftop of a concrete structure or a balcony to create a visually greened atmosphere. However, artificial turf gets tired soon because of its artificial nature. Further, when used for a long time, it is easy to discolor due to sunburn or the like, and it has been necessary to re-tension.

Therefore, as an alternative to artificial turf, an attempt to grow natural turf on a concrete surface has been studied.
The present inventor has also developed and has already filed various types of soil holding blocks used at this time. FIG. 3 shows a lawn soil holding block proposed in Japanese Utility Model Application No. 61-124899 (Japanese Utility Model Application Laid-Open No. 63-31757).

This lawn soil holding block is a polygonal frame type main body 31
And has a flange 32 formed on the upper edge thereof. A large number of water passage holes 33 are formed in the flange 32.
As shown in FIG. 4, a plurality of such grass soil holding blocks are aligned and arranged on the concrete surface. And up to the height of the frame body 31, Kanuma soil, earth and sand, perlite,
Porous water retaining layer with water absorbent material such as sponge and sponge
Forming 34. Next, on the water retaining layer 34, the topsoil for lawn cultivation
Heap up 35 and plant lawn 36 on this topsoil 35. When the water retention layer 34 and the top soil 35 are provided in this way, the water necessary for the growth of the lawn 36 is kept in the water retention layer 34 and is sequentially supplied to the lawn 36. In addition, if the required amount of water is larger than the required amount, the drainage channel 37 formed by the flanges 32 of the adjacent frame-shaped main body 31 is connected to the water passage 3
Flows in through and is discharged to the outside.

[Problems to be solved by the device]

When artificially forming the soil for growing lawn in this way and planting and growing the lawn on it, how quickly the root 36 of the lawn 36 is rooted to the topsoil 35 is an important point. That is, since the lawn 36 immediately after being rooted does not have enough roots in the top soil 35, the water is not sufficiently raised and the growth tends to be delayed.

In order to promote the growth of the lawn 36, it is considered that the topsoil 35 is mixed with a drug such as growth hormone. This is also one solution, but for that purpose, it is necessary to obtain a drug and adjust the topsoil 35, which makes the use of the grass soil holding block troublesome and tends to be avoided.

This problem is not limited to lawn cultivation, but is a common problem as long as a lawn soil retaining block is used to grow a plant in a bad environment such as a concrete surface. It also occurs, for example, when using lawn soil retention blocks to grow ornamental plants and vegetables.

Therefore, an object of the present invention is to accelerate the growth of plants by applying a magnetic force to the roots of the plants planted in the lawn soil holding block, and to quickly create an environment in which the lawn or the like is stretched.

[Means for Solving the Problems]

In order to achieve the object, the plant growing block of the present invention has a polygonal frame-shaped main body, a step portion formed on a side surface of the frame-shaped main body and having an upper surface in the frame, and a step lower than the step portion. A water-impermeable lower side wall, an upper side wall located above the step, a magnetic screen spanning the step, and an internal space of the frame-shaped body below the magnetic screen. A water retention layer and a topsoil layer filled in the internal space of the frame-shaped body above the magnetic screen,
A water passage hole for allowing the supplied water to flow out of the frame-shaped main body is formed in the step portion, and when a plurality of the frame-shaped main bodies are arranged adjacent to each other, the water is supplied between the adjacent frame-shaped main bodies. A drainage channel defined by the step and the lower sidewall is formed.

〔Example〕

As shown in FIG. 1, this grass soil holding block has a side surface of a frame-shaped main body 1 composed of an upper side wall 3 and a lower side wall 4 partitioned by a step 2. The frame-shaped main body 1 is a waste plastic or the like that can be cut as in the case of FIG. 3, and is formed into a polygonal shape such as a quadrangle or a hexagon so that no gap is formed between the adjacent plastics. There is. Also, the step 2
A large number of water passage holes 5 are formed in the upper side wall 3, and a flange 3a extending outward is formed at the upper edge of the upper side wall 3.

A magnetic screen 6 is provided on the step portion 2.
As the magnetic screen 6 shown in FIG. 1, a magnetized steel, ferritic stainless steel, or the like in which a linear shape is knitted in a net shape is used. The magnetic screen 6 may be fixed to the step portion 2 of the frame-shaped main body 1 or may be simply placed on the step portion 2 in a removable manner.

Further, instead of the reticulated magnetic screen 6, a screen in which both ends of a rod-shaped material are connected may be arranged in the step portion 2. Alternatively, a plurality of rod-shaped materials can be aligned across the step portions 2 on opposite sides. In this case,
Recesses or protrusions are formed on the step portion 2 at a predetermined pitch,
When the rod-shaped materials are arranged according to the concave portions or the convex portions, it is possible to keep a mutual gap constant.

FIG. 2 shows a state in which lawn is planted on a concrete surface using this lawn soil holding block.
Between the adjacent rod-shaped main bodies 1, the upper side wall 3 and the lower side wall 4 face each other, and the drainage channel 12 is formed. Then, inside the frame-shaped main body 1, up to the position of the step portion 2, the water retention layer 7
Kanuma soil, mountain sand, perlite, sponge, sponge etc. The magnetic screen 6 is located on the upper surface of the water retention layer 7, and the topsoil 8 is further raised on the magnetic screen 6, and the lawn 9 is planted on the topsoil 8.

At this time, the upper side walls 3 are erected up to near the surface layer in a state where the upper side walls 3 of the adjacent frame-shaped main bodies 1 are butted against each other. The protrusion acts as a support for the pedaling pressure when a person walks on the lawn 9, and prevents the soil from collapsing. In addition, in order to reliably prevent the water retention layer 7 from collapsing, it is possible to embed a cross-shaped reinforcing material inside the water retention layer 7.

When water is supplied to the soil formed in this way, the supplied water is absorbed and stored in the water retention layer 7 after passing through the top soil 8. In addition, a large amount of water overflows from the water retention layer 7, flows into the drainage channel 12 through the water passage hole 5, and is discharged to the outside. Further, the water stored in the water retention layer 7 gradually permeates the surface soil 8 and is supplied as necessary for the growth of the lawn 9.

At this time, if the surface of the concrete 10 is waterproofed, the water stored in the water retention layer 7 is the concrete.
Since it does not penetrate into 10, the water retention layer 7 is made of concrete.
Can be placed above 10. On the other hand, when the concrete 10 is not waterproofed, the water retention layer 7 is formed after the appropriate waterproof sheet 11 is stretched over the surface of the concrete 10.

The magnetic screen 6 embedded in the soil piled up on the concrete 10 generates a magnetic field in the periphery. Since this magnetic field is generated in the top soil 8 from which the root of the lawn 9 extends, it acts directly on the root to promote the growth of the lawn 9. The relationship between the magnetic field and plant growth has not been clarified yet, but it is being announced at various academic societies (SEE 6th Annual Conference of the Institute of Electrical Engineers of Japan S6-5 "Plant and magnetic field", Japanese Agriculture). Meteorological Society Proceedings 143 (1986) "Effect of magnetic field application on the growth of salad vegetables").

The following table shows the effect of the magnetic screen 6 thus embedded in the soil. As the magnetic screen 6, a steel wire having a diameter of 0.5 mm was knitted in a mesh shape with a mesh interval of 2.5 mm. A lawn 9 was planted in the soil in which the magnetic screen 6 was embedded, and the number of roots and the height (cm) of the lawn 9 were measured every elapsed days. In addition, as a comparative example, a case was shown in which lawn was grown without using the magnetic screen 6.

As is clear from Table 1, by applying a magnetic field,
The rate of increase in the number of roots has improved considerably. In this way, since the lawn 9 is rooted in the topsoil 8 in a short number of days, the growth rate of the lawn 9 is also increasing. Comparing this with the case where the magnetic screen 6 is not used, the growth of the lawn 9 as early as about 5 days can be seen immediately after the lawn 9 is planted and at the time when the rooting is most needed.

Further, the magnetic screen 6 also serves to prevent the collapse of the water retaining layer 7 when it is arranged between the water retaining layer 7 and the top soil 8 as shown in FIG. Therefore, even if some pressure is applied to the lawn 9, the growth of the lawn 9 is not adversely affected.

In addition, the magnetic screen 6 placed on the step portion 2 is positioned.
Is also effective in maintaining the water retention performance of the water retention layer 7 for a long period of time. That is, since the lower side wall 4 of the water retaining layer 7 is suppressed from the side surface by the impermeable lower side wall 4 and from the surface by the magnetic screen 6, the water absorbing material that is easily accompanied by running water is reliably maintained in the water retaining layer 7. To be done. On the other hand, the surplus water flows into the drainage channel 12 through the water passage hole 5 formed in the step portion 2 after passing through the top soil 8 or overflowing from the water retention layer 7.

As a result, a constant amount of water is always stored in the water retention layer 7. The top soil 8 is also maintained at a constant humidity.
In this way, since the magnetic force from the magnetic screen 6 acts on the lawn 9 maintained in a favorable growing environment, it is presumed that the lawn 9 is further promoted to grow as shown in Table 1 above. It

In addition, in the above example, the case where the lawn was raised was also described. However, it goes without saying that the plant growing block of the present invention is similarly used for other plants.

[Effect of device]

As described above, in the present invention, by incorporating the magnetic screen into the plant growing block, the soil necessary for growing the plant is reinforced, and the rooting and growth of the plant are promoted by the action of the magnetic field. There is. In particular, since the action of this magnetic field has a great influence on the time immediately after planting, it facilitates the growth of plants in places where water supply is difficult, such as concrete surface. Moreover, since the water retention performance of the water retention layer is maintained in a good state for a long period of time by the magnetic screen, a better plant growing environment can be obtained.
