Description

  The present invention relates to a plant cultivation tank that can grow and transport plants such as vegetables and fruits.

  Conventionally, in order to cultivate vegetables and fruits, they are generally cultivated by open field cultivation and greenhouse cultivation using a cultivation room such as a plastic house or a glass house. In outdoor cultivation, vegetables and fruits are cultivated by directly planting seedlings or sowing seeds on the ground.

  On the other hand, greenhouse cultivation such as a greenhouse is carried out in cases where plants need to control the temperature and the amount of water, or when the cultivation is carried out while shifting the shipping time or avoiding risks such as bad weather. In this greenhouse cultivation, in general, vegetables and fruits are cultivated by planting seedlings or sowing seeds directly on the ground in the cultivation room.

  However, even when greenhouse cultivation is performed, it is not always necessary to carry out in the cultivation room in all processes of the germination time, the growth time, and the harvest time of the plant.

  For example, plants that can be cultivated in the cultivation room only during germination and seedlings, plants that can be cultivated in the cultivation room until the harvest period, plants that can be managed in the cultivation room only during the flowering period, and those that are managed in the cultivation room only in winter There are also good plants.

  Even in greenhouse cultivation in a greenhouse or glass house, if it is directly cultivated on the ground, at least a long period from planting to harvesting occupies the cultivation room with one kind of plant.

  Farmers earn their income only after harvesting, so they are cultivated using cultivation tanks that can be transported inside and outside the cultivation room. Other plants are also cultivated in the vacant cultivation room.

  A planter made of a synthetic resin is widely known as one that can be transported in and out of a cultivation room. In Patent Document 1, a planter made of cardboard is disclosed as a plant cultivation tank for growing plants.

Japanese Patent Laid-Open No. 2002-223641

  However, the cultivation method using a normal plant cultivation tank has a limited amount of soil and sunlight on the side of the cultivation tank other than the soil surface as compared with the cultivation method planted and cultivated directly on the ground. Hits. Therefore, there is a problem that it is easily affected by ambient temperature and direct sunlight, and the temperature of the soil becomes too high or too cold.

  Further, the planter made of corrugated cardboard according to Patent Document 1 is also inexpensive and light, but in growing plants, the soil temperature also has a large effect, and depending on the soil temperature, the roots may burn and die, or the growth may be poor. Sometimes it becomes.

  The object of the present invention is to provide a plant cultivation tank that eliminates the above-mentioned problems, has a heat retention effect that prevents the soil temperature from becoming too high and is not too cold, and is inexpensive, lightweight, and easy to handle using a cardboard board. There is to do.

  The plant cultivation tank according to the present invention for achieving the above object comprises a box body in which a corrugated board is assembled, the upper surface is opened, and a hole is provided in the bottom, and these are placed on the upper sides of the four side plates of the box. The slope plates that are higher than the side plates of the side wall are extended upward, and the slope plates are bent inside the box so that the tip thereof is inclined to reach the bottom of the box. Thus, an inverted trapezoidal concave portion for putting soil into the box is formed, and a waterproof measure is taken for the entire circumference of the box.

  The plant cultivation tank which concerns on this invention prevents that a soil temperature changes rapidly with the heat retention effect of a corrugated board, and can be disposable cheaply.

It is sectional drawing along the BB line of FIG. It is a perspective view of the plant cultivation tank of the state covered with the synthetic resin sheet. It is sectional drawing of the hole of a bottom face. It is a block diagram of the mount which mounts a plant cultivation tank.

The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 shows a developed plan view of a corrugated board 2 before assembling a box 1 used as a plant cultivation tank. The material of the box 1 is a corrugated cardboard plate 2. The corrugated cardboard plate 2 is cut into a predetermined shape so as to be assembled into the box 1, and a valley fold line indicated by a dotted line is formed.

  The corrugated board 2 has four side plates 2a to 2d connected in the lateral direction, and bottom plates 2e to 2h are extended on the lower sides of the side plates 2a to 2d, respectively. In addition, slope plates 2i to 2l extend upward on the upper sides of the side plates 2a to 2d, respectively, and the height of the slope plates 2i to 2l is larger than the height of the side plates 2a to 2d. Further, for example, three holes 2m each having a diameter of about 3 cm are provided in the bottom plates 2e and 2g.

  The side plate 2a is provided with an adhesive piece 2n for bonding to an adjacent side plate 2d at the time of assembly, and the inclined plates 2i to 2l have locking pieces 2o to be locked to the adjacent inclined plates 2i to 2l at the time of assembly. 2v is attached.

  Since the corrugated board 2 has corrugated paper sandwiched between upper and lower separate papers, the corrugated board 2 has a corrugated cross section, and the direction of the corrugated parts is the side plates 2a to 2d. In order to increase the strength of the box 1, it is preferable that the slope plates 2 i to 2 l be in the height direction.

  When distributing the box 1 as a product, the manufacturer bonds the side plates 2a and 2d with an adhesive using an adhesive piece 2n, forms a loop in which the side plates 2a to 2d are connected, and is folded. Ship.

  The user folds the folded corrugated board along the valley fold line shown by the dotted line in FIG. 1 and assembles it into the shape of the box 1 as shown in FIGS.

  FIG. 2 is a perspective view of the box 1 in an assembled state. The outer shape of the box 1 is a rectangular parallelepiped shape whose upper surface is open. For example, the long side of the outer shape is about 60 cm, the short side is about 30 cm, and the depth is About 15 cm. 3 is a plan view, FIG. 4 is a cross-sectional view taken along line AA in FIG. 3, and FIG. 5 is a cross-sectional view taken along line BB. Of course, the box 1 may be a cube.

  When assembling into the box 1, the side plates 2a to 2d connected in a loop shape of the folded corrugated cardboard plates are expanded into a square, the bottom plates 2e to 2h are bent, and the bottom plates 2e to 2h are butted together. Alternatively, a bottom surface is formed by overlapping, and an adhesive tape is applied to the butted portion to retain the shape.

  Next, the slope plates 2i to 2l are folded inward from the upper sides of the side plates 2a to 2d until the tips thereof reach the bottom plates 2e to 2h, respectively, and are inclined obliquely. Thereby, the inner side of the box 1 is made into the inverted trapezoidal recessed part S1 by the slope plates 2i-2l and the bottom plates 2e-2h. In the process of this assembly, the locking pieces 2o to 2v are folded between the inclined plates 2i to 2l to lock the inclined plates 2i to 2l, and the shape of the box 1 is maintained. A total of six holes 2m are located on the bottom surface.

  Since the box 1 is formed by assembling the corrugated board 2 as described above, it is necessary to take a waterproof measure for the corrugated board 2 when the soil is actually put into the recess S1. For example, after inserting the box 1 into a resin sheet bag 3 having a waterproof bag shape such as polyethylene having an opening, the opening is sealed with a tape or the like after the resin sheet bag 3 is brought into close contact with the outer shape of the box 1 Seal with. Thereby, the plant cultivation tank 4 with which the whole periphery was covered with the resin sheet bag 3 as shown in FIG. 6 is obtained.

  Thereafter, the portion of the resin sheet bag 3 where the bottom plate 2e, 2g hole 2m is located is heated by a heat gun or the like, so that the resin sheet bags 3 on both sides of the hole 2m are melted as shown in FIG. Join. Thereby, the resin sheet bags 3 on both sides are connected to each other, and a drainage hole 3a having a diameter of about 1.5 cm, for example, sealed with respect to the bottom plates 2e and 2g is formed.

  In this way, by performing waterproofing by sealing with the resin sheet bag 3, water does not enter the box 1 from the outside.

  In addition, the color of the resin sheet bag 3 may be a white system that hardly absorbs heat in the case of plants that prefer a relatively cool soil temperature, and a black system that easily absorbs heat in the case of plants that prefer a warm soil temperature. Is preferred.

  For such a plant cultivation tank 4, soil is filled into the inverted trapezoidal concave portion S <b> 1 surrounded by the four slope plates 2 i to 21, and vegetables and fruits are cultivated. In order to prevent the soil from flowing out from the holes 3a before filling the soil, it is preferable to lay a net made of synthetic resin, for example, on the bottom surface.

  Of the water irrigated to the soil, excess water is drained out of the plant cultivation tank 4 through the slope plates 2i to 2l and the holes 3a, so that drainage is good.

  The plant cultivation tank 4 includes four substantially sealed space portions S2 surrounded by the side plates 2a to 2d, the bottom plates 2e to 2h, and the slope plates 2i to 2l, and further covered with the resin sheet bag 3. If the ambient temperature rises or the side plates 2a to 2d are irradiated with direct sunlight, the air in the space S2 is warmed. At this time, the air from the outside does not directly enter the space S2, and for example, when the ambient temperature rises, the heat applied to the side plates 2a to 2d is transferred to the air existing in the space S2 by heat conduction. As a result, the space S2 is gradually warmed.

  However, since the thermal conductivity of air is low, the air in the space portion S2 is less than the conventional simple plastic resin planter that does not have a space corresponding to the space portion S2 and the planter made of corrugated board of Patent Document 1. Since it acts as a heat insulator, there is little rapid heat conduction to the soil. Although it is inevitable that the heat of the outside air is directly transferred from the upper part of the plant cultivation tank 4 to the soil, the air in the space S2 warmed by the side plates 2a to 2d gradually passes through the slope plates 2i to 2l. Will be transmitted to the soil.

  On the other hand, when the ambient air temperature falls at night, the air in the space S2 plays a role of a heat insulating material, so that the heat of the soil causes the slope plates 2i to 2l and the side plates 2a to 2d. This makes it difficult to conduct heat to the outside. As described above, since the rapid temperature change of the soil is controlled by the heat insulation and the heat retaining action by the space S2, the adverse effect on the root of the plant can be further reduced, and the good growth of the plant can be promoted.

  In addition, since the plant cultivation tank 4 in the present embodiment is composed of the corrugated board 2 and the resin sheet bag 3, it is inexpensive and lightweight. It can be brought into and out of a cultivation room such as a glass house. In some cases, it can be transported as it is to the kitchen.

  As a result, the plant cultivation tank 4 can be brought into and out of the cultivation room at the optimal time and state for the plant to be cultivated, and at the same time, it is possible to easily cultivate multiple types of plants, thereby improving profits. Can do. Furthermore, when the plant cultivation tank 4 is lifted, there is a touch that has flexibility compared to a plant cultivation tank made of synthetic resin, and operations such as transportation can be easily performed.

  The use of the plant cultivation tank 4 can be applied not only to farmers but also to cultivation of vegetables and flowers in verandas and gardening in ordinary households.

  In this embodiment, the plant cultivation tank 4 is waterproofed by covering it with the resin sheet bag 3, but instead of the resin sheet bag 3, a waterproof sheet is attached to the outer surface of the box 1, or a waterproofing agent or the like. It is also possible to take a waterproof measure by applying.

  Further, when the use of the plant cultivation tank 4 is finished, the resin sheet bag 3 is broken and the box 1 is taken out and disposed of as it is.

  FIG. 8 is a block diagram of a pedestal that can be suitably used when cultivating a plant using this plant cultivation tank 4 in a cultivation room. A plurality of casings 11 made of corrugated board and having a large internal space are arranged in the cultivation room, and lightweight columnar bodies 12 made of two synthetic resin foams are placed on these casings 11 in parallel. Is covered with a vinyl sheet 13.

  On such a gantry, the plant cultivation tank 4 is arranged so that the bottom hole 3 a is located between the two columnar bodies 12. Thereby, since the water which flowed out from the plant cultivation tank 4 through the hole 3a falls between the columnar bodies 12 and flows out on the vinyl sheet 13, the water from the plurality of plant cultivation tanks 4 is collected in one place and drained. Can do.

  Further, the casing 11 has a large internal space. When a large number of casings 11 are used when heating the cultivation room, the thermal load in the cultivation room is reduced by the volume of these casings 11, so Even if the temperature in the body 11 rises, heating expenses and the like can be saved. Further, the space between the columnar bodies 12 also functions as a space having a heat insulating and heat retaining effect.

  In addition, by placing the plant cultivation tank 4 being cultivated on a frame, the equipment cost is reduced and moisture from the ground can be prevented. The plant cultivation tank 4 is slid on the columnar body 12 so that the plant cultivation tank 4 can be easily transported to the inside and outside of the cultivation room, and the work in the cultivation room is not carried out in a middle waist posture. There are few.
