BACKGROUND OF THE INVENTION
The present invention relates to a plant cultivation bed.
[0002]
[Prior art]
Conventionally, as a bed for plant cultivation, for example, a bed 100 for plant cultivation as shown in FIG. 4 is used. In the plant cultivation bed 100, fixed pipes 310 and 320 are disposed substantially horizontally and substantially opposed to each other on upper portions of support pipes 210 and 220 that are erected on both sides. In between, the culture medium receiving sheet 500 which has the drainage hole 510 is arrange | positioned. The upper surface of the culture medium receiving sheet 500 is filled with the culture medium 110, and the drainage liquid 120 discharged from the culture medium 110 is dropped from the drainage hole 510 and collected by the basket 700 disposed below the culture medium receiving sheet 500. ing.
[0003]
By the way, culture media such as soil and rock wool used here usually become unsuitable for good cultivation due to the accumulation of waste materials after a period of use of 1 to 2 years. Therefore, in order to make the medium last longer than the above-mentioned period of use, at the appropriate time, after all the medium is once immersed in water, the liquid is drained and disinfection for killing germs of the medium is performed.
[0004]
[Problems to be solved by the invention]
However, the plant cultivation bed 100 shown in FIG. 4 is disposed away from the top of the jar 700 where the culture medium 110 receives the drainage, and quickly flows out of the drainage hole 510 even if water is allowed to flow. For this reason, it has been substantially impossible to perform the above-described sapling operation in this plant cultivation bed 100. For this reason, the culture medium 110 used was normally disposable in a cycle of 1 to 2 years.
[0005]
The present invention has been made in view of the above points, and in a plant cultivation bed of a type in which a culture medium is provided at a predetermined height away from the ground, which is easy to maintain a good rhizosphere environment, a sapling operation It is an object of the present invention to provide a bed for plant cultivation that makes it possible.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the plant cultivation bed of the present invention is a plant cultivation bed provided with a medium receiving sheet for medium filling installed at a predetermined height, below the medium receiving sheet, It has a drainage receiving sheet in which at least one side edge is provided to be movable up and down.
[0007]
In this case, at least one of the first and second fixed pipes disposed substantially horizontally at a predetermined height and substantially opposite to each other via the support pipes installed substantially vertically. A movable pipe that is disposed in a positional relationship that is substantially parallel to the pipe and is supported so as to be movable in the vertical direction via a support pipe that supports the one fixed pipe. Each side edge of the receiving sheet is fixed to the first fixed pipe and the second fixed pipe, respectively, and one side edge of the drainage receiving sheet is fixed to the first fixed pipe. The other side end edge may be fixed to the movable pipe.
[0008]
In addition, it is preferable that a discharge port is formed at an appropriate location of the drainage receiving sheet, and a discharge pipe is connected to the discharge port.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. In the figure, reference numeral 1 denotes a plant cultivation bed according to the present embodiment, and includes a support pipe 2, a first fixed pipe 31, a second fixed pipe 32, a movable pipe 4, a medium receiving sheet 5, and a drainage receiving sheet 6. It is comprised.
[0010]
The support pipe 2 is installed substantially vertically. Specifically, the strut pipe 21 on one side and the strut pipe 22 on the other side are erected substantially at a predetermined distance from each other, and each has a predetermined distance on a straight line. There are multiple installations.
[0011]
A plurality of first fixed pipes 31 are arranged on the upper side of the support pipe 21 on one side so as to extend substantially horizontally to the support pipe 21 on the one side, and the support pipe on the other side. A plurality of second fixed pipes 32 are arranged on the other side of the support pipes 22 on the other side. Therefore, the first fixed pipe 31 and the second fixed pipe 32 are disposed substantially horizontally at a predetermined height and substantially opposite to each other.
[0012]
The second fixed pipe 32 is supported via a substantially L-shaped joint member 8 that extends inward from the upper end of the support pipe 22 on the other side. As a result, a gap is formed between the vicinity of the tip of the joint member 8 and the support pipe 22 on the other side, so that the movable pipe 4 described below can be moved until it is located in this gap.
[0013]
The movable pipe 4 spans the other side strut pipe 22 and the other side strut pipe 22 which is arranged in plural so as to be substantially parallel to at least the second fixed pipe 32. It is arranged so as to be movable in the vertical direction along the support pipe 22. Specifically, a ring-shaped engaging member 41 is externally mounted around each support pipe 22 on the other side, and the movable pipe 4 is held by a pipe holding portion formed on the engaging member 41. ing. A positioning ring 42 having a set screw 43 is disposed around each support pipe 22 on the other side, below the engaging member 41. By tightening the set screw 43, the positioning ring 42 is arranged. Is fixed at an arbitrary position, and the position of the engaging member 41 whose lower end surface is in contact with the upper end surface of the positioning ring 42 and the position of the movable pipe 4 held by the engaging member 41 are also fixed. become.
[0014]
The culture medium receiving sheet 5 has a substantially concave cross section between the first fixed pipe 31 and the second fixed pipe 32, that is, the vicinity of the center is low, and both side edges are high. As described above, both side edges are respectively fixed to the first fixed pipe 31 and the second fixed pipe 32 by the sheet stopper 9 (see FIG. 3).
[0015]
The upper surface of the culture medium receiving sheet 5 arranged as described above is filled with a culture medium 11 such as soil or rock wool. Further, a drainage hole 51 is formed in the vicinity of the center of the medium receiving sheet 5, and an excess culture solution that has passed through the medium 11 during cultivation, that is, the drainage 12, passes through the drainage hole 51. It is discharged onto the drainage receiving sheet 6 described below. The drainage hole 51 may be a hole or a slit, but depending on the type of the culture medium 11, the diameter is usually about 1 mm or more if it is a hole and if it is a slit. The slit width is preferably about 1 mm or more in diameter. In addition, although an upper limit changes with the kind of culture medium 11, it is preferable to set it as the grade which a part of culture medium 11 does not fall. As the culture medium receiving sheet 5, a conventionally known waterproof plastic film or the like can be used. In addition, a non-permeable porous sheet (for example, manufactured by Seiwa Co., Ltd .: trade name “Luton”) that allows liquid to pass through but inhibits passage of plant roots may be used. In this case, it is advantageous in that it is not necessary to provide a drainage hole separately. However, since this porous sheet has a very small diameter of about 30 to about 50 μm, and when soil is used as a culture medium, it is easily clogged. It is preferable to use one in which the drainage hole 51 is formed.
[0016]
The drainage receiving sheet 6 is made of a waterproof plastic film or the like, and is below the culture medium receiving sheet 5, and fixes one side edge 61 to the first fixed pipe 31 and the other side edge 62. The movable pipe 4 is fixedly disposed. When the drainage receiving sheet 6 is normally cultivated, the movable pipe 4 is slid downward along the support pipe 22 on the other side so that the other side edge 62 is more than the one side edge 61. It arrange | positions so that it may be located in a low place (refer FIG. 2). As a result, a space 13 is formed between the culture medium receiving sheet 5 and the drainage receiving sheet 6. Since air constantly circulates in this space 13, a preferable rhizosphere environment can be maintained. For example, since oxygen is supplied to the rhizosphere through the drainage holes 51 formed in the culture medium receiving sheet 5, oxygen shortage in the rhizosphere can be prevented. In addition, since the space 13 is formed, the amount of the drainage liquid 12 that passes through the medium 11 can be visually checked, so that the supply amount of the culture solution to the medium 11 can be easily adjusted. Furthermore, since the culture medium receiving sheet 5 and the drainage receiving sheet 6 are isolated as described above, the drained liquid 12 discharged from the culture medium 11 does not come into contact with the culture medium 11 again, and there is excess in the culture medium 11. It is possible to prevent root rot of the cultivated plant due to accumulation of the culture solution.
[0017]
In addition, the drainage receiving sheet 6 slides the movable pipe 4 upward along the column pipe 22 on the other side when the liquid is liquid so that the other side edge 62 becomes one side edge 61. Are arranged so as to be located at substantially the same height as that of the second fixed pipe 32 (see FIG. 1). As a result, since the drainage receiving sheet 6 is arranged so as to wrap the medium receiving sheet 5 from the lower surface of the medium receiving sheet 5, the medium 11 is washed up to the upper surface of the medium 11 disposed on the medium receiving sheet 5. Therefore, it becomes possible to quickly collect the water 14 for the purpose.
[0018]
The drainage receiving sheet 6 is provided with a discharge port 15 at an appropriate location in order to discharge the drained liquid 12 accumulated in the drainage receiving sheet 6 or the water 14 washed with the culture medium 11 to the outside. Further, a discharge pipe 16 is connected to the discharge port 15 as a passage for discharging the drainage liquid 12 and the like to the outside. In the present embodiment, as shown in FIG. 3, a discharge port 15 is formed at one end of the drainage receiving sheet 6, and a first discharge extending downward from the discharge port 15 is formed in the discharge port 15. A discharge pipe 16 comprising a pipe 16a and a second discharge pipe 16b in which an end 16c of the first discharge pipe 16a is inserted from one end side and the other end is buried in the ground 17 Is connected. Of course, if the discharge pipe 16 is connected and extended, the drainage can be easily collected in a drainage storage tank (not shown).
[0019]
Here, the reason why the discharge pipe 16 is constituted by the two pipe members as described above is that the length of the discharge pipe 16 can be freely expanded and contracted according to the height at which the drainage receiving sheet 6 is arranged. That is, at the time of normal cultivation, since the drainage receiving sheet 6 (the discharge port 15 formed in the drainage receiving sheet 6) is positioned at a low place, the end 16c of the first discharge pipe 16a is the second discharge pipe. By being inserted deeply into 16b, the length of the discharge pipe 16 becomes shorter as a whole (see FIG. 2). On the other hand, since the drainage receiving sheet 6 (the discharge port 15 formed in the drainage receiving sheet 6) is located at a high position at the time of dripping, the end 16c of the first discharge pipe 16a is connected to the second discharge pipe. By being inserted shallowly into 16b, the length of the discharge pipe 16 becomes longer as a whole (see FIG. 1).
[0020]
The plant cultivation bed 1 configured as described above is used as follows. That is, at the time of normal cultivation, the movable pipe 4 is slid downward along the other side support pipe 22, and the drainage receiving sheet 6 has the other side edge 62 than the one side edge 61. Are also used so as to be located in a low place (see FIG. 2). On the other hand, at the time of dripping, first, the movable pipe 4 is slid upward along the support pipe 22 on the other side, and the drainage receiving sheet 6 is moved to the other side edge 62. It arrange | positions so that it may become substantially the same height as 61, ie, the substantially same height as the arrangement position of the 2nd stationary pipe 32. And the water 14 is inject | poured to the upper surface of the culture medium 11 so that the upper surface of the drainage receptacle sheet | seat 6 may be filled with the water 14, and a dripping is performed (refer FIG. 1).
[0021]
Of course, the bed 1 for plant cultivation of the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, only the other side edge 62 of the drainage receiving sheet 6 is connected to the movable pipe 4 so as to be movable up and down, and can be moved close to the culture medium receiving sheet 5. Can also be provided on one column pipe 21 so that one side edge 61 side can be moved up and down together with the other side edge 62 side.
[0022]
Further, the drainage receiving sheet 6 can be directly connected to the engaging member 41 that moves up and down without the movable pipe 4 interposed therebetween. Furthermore, the means for supporting the culture medium receiving sheet 5 at a predetermined height is not limited to the configuration using the support pipes 21 and 22 and the fixed pipes 31 and 32. For example, the medium receiving sheet 5 can be supported by being suspended from above the greenhouse.
[0023]
【The invention's effect】
According to the plant cultivation bed of the present invention, the drainage receiving sheet is disposed below the medium receiving sheet installed at a predetermined height, and at least one side edge is provided so as to be movable up and down. ing. Therefore, at the time of normal cultivation, a good rhizosphere environment can be given to the cultivated plant by arranging the drainage receiving sheet so as to be located in a low place. Moreover, at the time of the pouring, it is also possible to carry out the pouring work by adjusting the drainage receiving sheet to approach the culture medium receiving sheet.
