DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting box used for planting seedlings or saplings of plants and crops.

[0002]

2. Description of the Related Art Conventionally, in the case of planting using a box or the like that can be embanked inside, when planted seedlings or seedlings are supplied with water, the seedlings or seedlings are absorbed or retained in the roots or soil. If unreserved water remains stored in the lower part of the box body, it may cause root rot etc. of the seedling or seedling, so this kind of box is generally provided with a drain hole,
The water inside the box can be discharged to the outside.

[0003]

However, if the drainage hole is provided at a predetermined position of the bottom plate of the box, when a proper amount of water is supplied, the water is not absorbed or retained in the roots or soil of the seedlings or the seedlings. Since the drained water is discharged from the drain hole as needed, there is a problem that it is necessary to supply water regularly, which is troublesome.

Therefore, a drain hole is provided on the side of the box,
It is conceivable that an appropriate amount of water is held in the box body and the held water is supplied to the roots for a predetermined period after water supply.In such a case, for example, the box body is inclined on a slope or the like. When placed in the state, the water in the box body is biased to the lower side of the slope, the seedlings or seedlings on the lower side of the slope tend to cause root rot, or water is not retained on the upper side of the slope, and the upper side of the slope is not Seedlings or saplings of some plants tended to wither.

The present invention has been made in view of such a problem. Even when the box body is placed at an angle, an appropriate amount of water is almost uniformly held on the entire bottom surface of the box body. It is an object of the present invention to provide a planting box that can be kept.

[0006]

In order to solve the above-mentioned problems, a planting box according to the present invention is a box-shaped planting box that can be embanked therein. A partition reference surface that defines the bottom is formed, a plurality of recesses having a predetermined depth are formed by the partition reference surface over the entire bottom portion, and further, on the sides of the box, the inside and outside of the box are formed. Is formed at least at a position substantially equal to or higher than the section reference plane. According to this feature, when water is supplied into the planting box, a predetermined amount of water is held in the recess provided at the bottom, and excess water is discharged to the outside through the communication hole. While, when the planting box is disposed in an inclined state, the water is biased toward the lower slope side in the planting box and is discharged from the communication hole on the lower slope side,
Part of the water is stored in each of the recesses having a predetermined depth and is prevented from flowing out to the lower slope side, so that the water is uniformly held on the lower slope side and the upper slope side. Therefore, a plant planted by holding more than the required amount of water locally in the planting box within the appropriate period may cause root rot,
Conversely, the required amount of water is not supplied, and the plant does not die.

[0007] In the planting box of the present invention, it is preferable that a concave groove extending from the communication hole to an edge of the side is formed on the outer surface of the side. With this configuration, a plurality of planting boxes are continuously arranged so that the side plates are in contact with each other, and even when one communication hole is closed by the other side plate, the planting box is formed by the groove. Since a communication path between the inside of the planting box and the outside is ensured, the function of discharging water or supplying air is not impaired.

[0008] The planting box of the present invention is preferably provided with a plurality of projections on the lower surface of the bottom portion, the projections being in contact with the mounting surface of the box. With this configuration, the gap formed between the bottom surface of the bottom plate and the placement surface causes the stability of the planting box when the planting box is placed on a placement surface having an uneven surface. Is improved. Further, when a plurality of planting boxes are continuously arranged on the inclined surface, a water discharge path is secured below the planting boxes.

[0009] In the planting box of the present invention, it is preferable that a plurality of columns having a predetermined height are protruded at predetermined positions on the section reference plane. This makes it difficult for plants to grow above the columns, so that an effect similar to thinning can be obtained, and when the planting box is placed at an angle, the soil in the planting box is As a result, the soil is prevented from flowing to the lower side of the slope, the bias in the earth pressure is less likely to occur, and the circumference of the root is stabilized.

[0010] The planting box of the present invention comprises:
It is preferable that a plurality of slits extending in the vertical direction are formed on the inner surface of the side portion. By doing so, the roots of the seedlings or the seedlings tend to extend in the direction of the slits provided in the periphery, so that the roots are hardly entangled and the circumference of the roots is stabilized.

[0011] In the planting box of the present invention, it is preferable that at least one of the plurality of columns has at least one fin extending radially. In this way, the fins projecting outward from the support columns can effectively prevent the soil from moving downward on the slope.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 1 shows that a plant seedling P is planted using a planting box 1 as an embodiment of the present invention. The state shown is shown. The planting box 1 is formed in a box shape having an upper surface opened from a side plate 2 as a side portion and a bottom plate 3 as a bottom portion, so that the soil can be buried inside the planting box 1. Has become.

As shown in FIGS. 1 to 3, the bottom plate 3 has
The partition walls 4 are arranged in a matrix in plan view, and the upper surface 4a of the partition wall 4 defines a partition reference surface at the bottom of the planting box 1 and is positioned with respect to the upper surface 4a. In order to hold an appropriate amount of water in the planting box 1, a plurality of recesses 5 are formed independently of each other. In addition, the plurality of recesses 5 in the present embodiment are all substantially uniform in depth, and are formed at equal intervals over the entire bottom plate.

At the intersection of the partition walls 4 arranged in the vertical and horizontal directions, a plurality of pillars 7 for stably supporting around the roots of the planted seedlings are respectively erected at predetermined heights.
A plurality of round holes 6 are formed in the upper surface (section reference plane) 4a of the partition wall 4 except for the intersection where the pillars 7 are erected, and water is also held inside the round holes 6. Has become.

Further, a plurality of slits 8 are formed in the outer side surface of the column 7 and the inner side surface of the side plate 2 in the vertical direction.
Since the roots of the plant have the property of growing in the direction of a dark and narrow space, the slits 8 are formed in such a manner that the roots of the planted plants spread in the directions of the surrounding slits 8 respectively. , The roots are hardly entangled in the soil, and the rooting property is improved.

A plurality of communication holes 9 communicating with the inside and outside of the planting box 1 are formed at predetermined intervals on the four side plates 2 constituting the side surface of the planting box 1, respectively. The excess water in the storage box 1 can be discharged to the outside as appropriate, and in normal times, the soil and the outside are connected, and air is also supplied to the roots in the soil. Is to be prevented. In addition,
The communication hole 9 is formed so that the lowermost portion is located slightly above the upper surface 4a of the partition wall 4, as shown in FIGS. 3 and 5, but may be formed at almost the same height. Good.

A groove 10 extending to the lower end of the side plate 2 is formed on the outer surface of the side plate 2 from the communication hole 9, so that a plurality of planting boxes 1 are connected to each other as shown in FIG. In the case where the side plates 2 are provided adjacent to each other so as to be in contact with each other, even if one communication hole 9 is closed by the other side plate 2, communication between the communication hole 9 and the outside is maintained through the concave groove 10. It is supposed to be.

Further, since the tapered surface 2a which is inclined inward and downward is formed inside the upper end portion of the side plate 2, the soil is filled in the planting box 1 up to the vicinity of the tapered surface 2a. Sometimes, the upper end surface of the side plate 2 is hardly exposed to the outside, and the appearance from the upper surface is improved particularly when a plurality of planting boxes 1 are arranged adjacent to each other.

As shown in FIG. 3, a plurality of protrusions 11 project downward from the lower surface of the bottom plate 3, and when the planting box 1 is placed on the placement surface G, A gap is appropriately maintained between the lower surface 3a of the bottom plate 3 and the mounting surface G.

The planting box 1 according to the present embodiment, which is constructed as described above, is formed by integral molding of foamed polypropylene, so that it is lightweight and easy to carry, and can be used for planted seedlings. In addition to having heat insulation, heat retention, and antifungal effects, it is also excellent in workability, so that construction work such as increasing the number of communication holes can be easily performed on site. Needless to say, the planting box 1 is not limited to foamed polypropylene, and may be made of various materials such as wood and resin, and the shape is not limited to a square, but may be a circle or a polygon. Good.

Next, a planting method using the planting box 1 and its operation will be described with reference to the drawings.
In the case of planting using the planting box 1 as shown in FIG. 4, according to the contents to be planted in each recess 5 (or to the extent that it covers the upper surface 4a of the partition wall 4) as shown in FIG. The water-reinforcement aggregate 12 is spread all over, and the nutrient soil 13 is appropriately laid on the upper side to plant seedlings. 14 is a communication hole 9
This is a net for preventing the outflow of soil from the soil, and is provided in advance on the inner surface of the side plate 2 before embankment.

When rainfall or artificial water supply is performed, water that falls downward without being absorbed and held in the roots and soil of the seedlings is held in each recess 5 as shown in FIG. In the figure, the hatched portion in the concave portion 5 indicates water), and when more water is supplied, all excess water is discharged to the outside through the communication hole 9. Therefore, an appropriate amount of water is retained in the concave portions 5 provided in the entire bottom plate 3 by water supply, and the water retained in the concave portions 5 is supplied to the roots for a predetermined period after the water supply. Since labor can be omitted and unnecessary water is discharged as needed, root rot and the like can be effectively prevented.

In particular, such a planting box 1 is used by being placed on an inclined surface G 'inclined at a predetermined angle θ with respect to a horizontal plane as shown in FIGS. 7 (a) and 7 (b). In this case, even if the water is supplied so as to accumulate above the concave portion 5 on the upper side of the slope as shown in FIG. 7A, finally, as shown in FIG. All the water above the lowermost communication hole 9 is appropriately discharged to the outside through the communication hole 9.

After the water is discharged, a small amount of water is normally stored only on the lower side of the slope in the planting box 1. Since water is equally held in each of the seedlings 5, the same amount of water is supplied to each of the seedlings planted on the upper slope side and the lower slope side. Therefore, when water is supplied to the planting box 1 placed in an inclined state, the same amount of water can always be supplied to the entire bottom surface 3 without partially changing the water holding amount. The root rot and withering of the seedlings are effectively prevented.

Further, since a plurality of columns 7 having a predetermined height are erected, even when the planting box 1 is inclined, the soil is supported by the columns 7 and flows out to the lower side of the slope. Is prevented, and the bias of the earth pressure toward the lower side of the slope is suppressed, so that the root circumference of the seedling is stabilized.

Since the posts 7 are provided at predetermined intervals, even when seedlings are randomly planted on the soil surface, for example, the roots of the seedlings are unlikely to extend downward above the posts 7 and hinder growth. Therefore, the same effect as the thinning can be obtained.

FIG. 8 shows another embodiment of the present invention. Of the plurality of columns 7 in the present embodiment, fins 15 are provided on the outer surface of a predetermined column 7 so as to extend radially. By providing the fins 15, even when the planting box 1 is tilted in an arbitrary direction, a wide space is linearly formed between the columns 7 from the upper slope side to the lower slope side. Since the soil is not formed, the soil is effectively prevented from moving to the lower side of the slope. The arrangement pattern, shape, and the like of such fins 15 are arbitrary and can be variously modified. Further, even without providing such fins 15, by merely changing the arrangement pattern of the columns 7, a wide space is not formed linearly between the columns 7 from the upper slope side to the lower slope side. It is also possible.

Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are changes and additions without departing from the gist of the present invention. Included in the invention.

For example, the partition wall 4 may be plate-shaped, and the partition pattern can be variously deformed, and recesses of the same shape are always formed at equal intervals as in this embodiment. It does not have to be provided as such.

The height, shape and the like of the support 7 are arbitrary, and the support 7 may be provided so as to be exposed on the embanked soil surface.

Needless to say, such a planting box 1 is not limited to the planting of plant seedlings as in the embodiment. It can be used in a wide range of fields, such as planting.

[0032]

The present invention has the following effects.

(A) According to the first aspect of the present invention, when water is supplied into the planting box, a predetermined amount of water is held in the concave portion provided at the bottom, and excess water is communicated. When the planting box is arranged in an inclined state while the water is discharged to the outside from the hole, the water is biased to the lower side of the slope in the planting box, and the communication hole on the lower side of the slope is provided. Although some water is stored in each recess having a predetermined depth and is prevented from flowing out to the lower slope side, water is evenly distributed to the lower slope side and upper slope side respectively. Will be retained. Therefore, the planted plant may have roots rot due to the holding of more water than necessary in the planting box locally within the appropriate period, or the required amount of water may not be supplied, and the plant may die. There is no.

(B) According to the second aspect of the present invention, a plurality of planting boxes are arranged continuously so that the side plates are in contact with each other, and one communication hole is closed by the other side plate. In this case, the communication between the inside of the planting box and the outside is ensured by the concave groove, so that the function of discharging water or supplying air is not impaired.

(C) According to the invention of claim 3, even when the planting box is placed on a mounting surface having an uneven surface, the planting box is formed between the bottom surface of the bottom plate and the mounting surface. The clearance provided improves the stability of the planting box. Further, when a plurality of planting boxes are continuously arranged on the inclined surface, a water discharge path is secured below the planting boxes.

(D) According to the invention of claim 4, since it is difficult for the plants to grow above the columns, the same effect as thinning out can be obtained, and the planting box is placed with inclination. Since the soil in the planting box is sometimes supported by the pillars, the soil is prevented from flowing to the lower side of the slope, the earth pressure is less likely to be biased, and the circumference of the root is stabilized.

(E) According to the fifth aspect of the present invention, the roots of the seedlings or the seedlings tend to extend in the direction of the slit provided in the periphery, so that the roots are hardly entangled and the root circumference is stabilized.

(F) According to the sixth aspect of the present invention, even when the box is inclined in an arbitrary direction, any of the pillars is located on the lower side in the vicinity of the soil at a predetermined position in the box. Due to the existence, the soil is reliably prevented from moving downward.
