Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1A is a perspective view of a plant growing box according to the present invention, and FIG. 1B is a partially omitted view showing a state in which the left end side wall portion of the plant growing box shown in FIG. It is a perspective view.

  A plant growing box 1 shown in FIG. 1 is used alone as a planter or container by being placed on a garden, a veranda or the like, and has a rectangular bottom portion 2 and long and opposite sides of the bottom portion 2 facing each other. Front and rear side wall portions 3a, 3b each rising from the edge, and left and right side wall portions 3c, 3d rising from the short edge of the bottom 2, respectively, are provided on these four side wall portions 3a, 3b, 3c, 3d. It is a box body which is surrounded and has an open upper surface and has a storage space 4 inside. Each of the side wall portions 3a, 3b, 3c, 3d and the bottom portion 2 is formed by flocking a short synthetic fiber such as nylon 66 on the surface of the metal plate (the inner surface of the box) (FIG. 1). In (b), a plate material on which is indicated by shading) is used. In the flocking process, surface treatment such as galvanization is applied to the surface of an iron plate rolled to a predetermined thickness, and then an adhesive such as an acrylic adhesive is applied to form an adhesive layer. In addition, the process of densely planting short fibers of nylon 66 in a state of being erected by static electricity can be mentioned, but is not limited to this, and the flocked layer 5 having water retention and water conductivity by flocking is formed. Any processing method can be used as long as it is possible.

  A part of the bottom part 2 is set lower than the inner surface of the other bottom part 2 to form a lower part, and a drain hole 6 is opened at a position higher than the lowest position of the lower part. The lower part of the lower part is used as a water storage part 7, and the flocking layer 5 at the bottom 2 including the periphery of the drain hole 6 and the flocking layer 5 at the side wall part 3 are continuously connected from this water storage part 7. Specifically, a part along the edge of the long side of the bottom portion 2 is formed in the longitudinal direction with a groove having a rectangular or trapezoidal or V-shaped cross section as a lower portion, and the opening is higher than the bottoms of the grooves on both sides. These inner edges are connected by a flat surface, and a plurality of round drain holes 6 are formed along the longitudinal direction at the approximate center of the flat surface. Then, the front and rear side walls 3a and 3b are formed by vertically erecting the edge of the opening of the groove located on the side opposite to the flat surface. The upper ends of the side wall portions 3a and 3b are rounded by folding back (heming fold) inward (bottom side).

  In this way, the bottom plate 2 and the front and rear side wall portions 3a and 3b are formed by bending the iron plate having the flocking layer 5, and when the drain hole 6 is formed in the bottom portion 2 by punching, the long side of the bottom portion 2 is formed. The two grooves formed along the surface serve as the water reservoir 7, and the flocked layer 5 at the bottom 2 including the periphery of the drain hole 6 and the flocked layer 5 at the side wall are cut off from the water reservoir 7. It is not continuous.

  Further, the side wall portions 3c and 3d at the left and right end portions are walls that block an opening (a small opening) surrounded by the bottom portion 2 and the end side portions of the front and rear side wall portions 3a and 3b. And the same metal plate as the metal plate used for the front and rear side wall portions 3a and 3b (an iron plate on which the flocking layer 5 is formed in advance) is bent. Specifically, the connection pieces 3e and 3f are located on the bottom side with respect to the wall surface from the side edge of the wall surface that is slightly larger (corresponding to the plate thickness of the iron plate) than the opening between the end side portions of the front and rear side wall portions 3a and 3b. It is bent at a substantially right angle toward the surface. In order to attach the left and right side wall portions 3c and 3d formed in this way to the front and rear side wall portions 3a and 3b, the side connection portions 3e and 3f are directed toward the side wall portions 3a and 3b, and the side wall portions 3a and 3b end side portions. The connecting pieces 3e and 3f are overlapped with the end side portions of the side wall portions 3a and 3b, and the overlapping portion is fixed by a known fixing means such as a screw, rivet, caulking, and fastener. Fix it. And the sealing agent is filled in the clearance gap between the inner surface of these side wall parts 3c and 3d and the edge part of the water storage part 7, and the water storage part 7 is sealed. When sealing is performed in this manner, it is possible to prevent water in the water reservoir 7 from inadvertently leaking out from the joint portion with the bottom 2 or the side wall 3.

  The side wall portions 3c and 3d shown in FIG. 1 are formed by bending the connection pieces 3e and 3f only on both sides of the wall surface. The bent side 3g may be formed at right angles, that is, in the horizontal direction, and the bent side 3h extending from the lower edge may be formed. In this case, it can also be molded by drawing.

When the plant growing box 1 having such a structure is used, an appropriate size stone or net is placed in the drainage hole 6 to prevent sediment falling, Add soil mixed with humus. Then, plant your favorite flowers and water them as evenly as possible using a watering can.
In addition, a porous material such as a net or a punching board is provided on the upper surface of the opening of the water storage unit 7 so that even if water flows into the water storage unit 7, the sediment does not easily flow. You may comprise so that it may not reduce by inflow of.

  When water is supplied to the soil in this way, the soil gradually wets deeply from the soil on the surface to the soil below it. That is, water is retained between the soil particles by deeply soaking from the surface soil. Further, when water reaches the side wall portions 3a, 3b, 3c, and 3d at the front and rear and left and right end portions, the flocked layer 5 on the inner surface of each side wall portion 3 has water retention, so that the inner surface of each side wall portion 3 is simply Not only is it wet with water, it is also retained by the flocking layer 5.

  Then, when the amount of water supplied from the surface of the soil increases and exceeds the water retention capacity in that portion in order from the top soil, all the excess will flow down sequentially so as to soak into the bottom soil, and the bottom 2 The water flowing down to the flat part of the water spreads over the flat part. And the water which reached the drain hole 6 will be drained outside from the drain hole 6. On the other hand, the water that has flown over the flat part without reaching the drain hole 6 finally flows into the water storage part 7 from the flat part and is stored. In addition, when water is overdoed and the water retention capacity of the soil is exceeded and the water storage unit 7 becomes full, the excess water is discharged from the drain hole 6 to the outside. Therefore, even if the water storage part 7 is provided in the bottom part 2, it is possible to prevent water from being accumulated in the bottom part 2 to the extent that the roots rot.

  As described above, when water is applied to the surface soil, the water gradually infiltrates from the surface soil and is retained between the particles of the soil, and the side walls 3a, 3b, 3c, 3d of the front and rear and left and right ends are also retained. Since water is retained in the flock layer 5 on the inner surface, if the water in the soil decreases after the plant absorbs moisture in the soil or evaporates from the surface of the soil, the flock layer 5 in each side wall 3 Moisture held in the oozes out into the soil and moistens the soil. In other words, when the moisture in the soil decreases and dries, the soil absorbs the moisture retained in the flocked layer 5 and increases the moisture content.

  Further, in the plant growing box 1 according to the present invention, since water is stored in the water storage section 7 of the bottom 2 at the time of sufficient watering, the water in the water storage section 7 is stored in water. Starting from the flocked layer 5 on the inner surface of the part 7, the capillary force of the series of flocked layers 5 is transferred from the flocked layer 5 on the bottom 2 to the flocked layer 5 on each side wall 3, and the flat part of the bottom 2 is horizontally In addition to diffusing in the direction, the flocked layer 5 is lifted up on the inner surface of each side wall 3 standing upright. Therefore, if water is stored in the water storage part 7, when the moisture in the soil is absorbed and the water retention amount is reduced, the flocked layer of the entire inner surface of the bottom part 2 and the side wall part of the plant growing box 1 5 is replenished with water transmitted from the water reservoir 7. For this reason, when moisture in the soil is sucked up or evaporated by the plant, water held in the surrounding flocking layer 5 is replenished in the soil, thereby preventing water shortage in the soil, For this reason, even if the interval of watering is made longer than before, there is no problem.

  In addition, since the synthetic | combination short fiber is dense with the fixed density, the flock layer 5 can exhibit capillary force similarly in any site | part. For this reason, the flock layer 5 is far superior in the ability to transmit water compared to the water permeability of soil with greatly different particle sizes and large fluctuations. The hair transplantation layer 5 in the part 7 is transmitted to the hair transplantation layer 5 connected in series and stably supplied to the hair transplantation layer 5 of each side wall 3. In particular, in the case of soil mixed with humus soil, withered branches and leaves are contained, the water permeability by the soil is unstable, and it is difficult for water to permeate upward from the water reservoir 7. On the other hand, if it is the flocked layer 5 connected in series from the bottom part 2 to the side wall part 3, the stable water conveyance force by capillary force can be expected. Therefore, the water replenishment function by the series of flocking layers 5 is more stable and surely able to supply water to the plant as compared to relying entirely on the water penetration ability by the soil.

Next, a description will be given of a plant growing box unit in which a plurality of stages of plant growing boxes 1 are arranged, and a connecting member is provided between the plant growing boxes 1 positioned above and below to be integrated into a unit.
