In the method described in Patent Document 1, a seedling grown with a sponge as a support is placed in a hole provided in a pipe. However, since the root of the seedling is insufficient immediately after planting, the nutrient solution in the pipe There is a running cost problem such as the need to raise the water level and the need for a powerful pump. On the other hand, if it is intended to sufficiently grow seedlings in another place, a separate growth house is required, which is troublesome. Furthermore, there is a risk that the plant will die if the water level of the nutrient solution falls due to a malfunction of the pump and the nutrient solution does not reach the roots.
On the other hand, as described in Non-Patent Document 1, in the method of installing a seedling grown using a pot in a hole provided in a pipe, it costs a cost to prepare the pot and soil to be packed in the pot, and the disposal after the growth In addition, since it is necessary to make a relatively large hole in the pipe, a gap is likely to be formed between the pot and the pipe hole, and rainwater is mixed from the gap to dilute the solution. there's a possibility that.
This invention solves the said problem in a pipe hydroponic cultivation apparatus.

As a result of examining the above problems, the present inventors have used a hydroponic cultivation tool in which a support member for supporting and growing a plant and a liquid supply means for supplying nutrient solution to the support member are fixed. The present inventors have found that the above problems can be solved.
The present invention includes a support member that supports and grows a plant, and a liquid supply unit that is disposed in contact with the support member and supplies a nutrient solution to the support member. The support member and the liquid supply unit This is a hydroponics tool that is fixed.

Moreover, in this invention, it is preferable that the said liquid supply means is a nonwoven fabric, and it is preferable that the said supporting member is a synthetic sponge.
Moreover, it is preferable that one end of the liquid supply means is fixed to the support member, and the liquid supply means holds the fertilizer, and this is installed in an opening of a container such as a plastic bottle to form a hydroponics kit. Is also another embodiment of the present invention.

  Furthermore, in another embodiment of the present invention, a pipe hydroponic cultivation system for growing a plant installed in the opening by feeding a nutrient solution to a pipe having a plurality of openings, the opening It is a pipe hydroponic cultivation system which installed the above-mentioned hydroponic cultivation tool.

  In the hydroponic cultivation tool of the present invention, since the liquid supply means is fixed to the supporting member that supports and grows the plant, the flowing level of the nutrient solution in the pipe is low by applying it to the pipe hydroponic cultivation system. It is possible to supply liquid to the support member even at the water level. Therefore, there is no risk that the roots will die without being supplied with water. Moreover, since the water level can be kept low, the running cost can be suppressed. Moreover, since the hydroponics tool of this invention can be installed in the hole provided in the pipe directly, without using a pot, it is not necessary to prepare a pot and soil and disposal after use is also easy. In addition, since the size of the hole provided in the pipe can be reduced and the support member and the hole can be installed in close contact with each other, nourishment due to the mixing of rainwater from the gap between the hole provided in the pipe. The dilution of the liquid can also be prevented.

Hereinafter, the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to the contents described below, and can be arbitrarily changed and implemented without changing the gist thereof. is there.
In addition, the drawings used for the description all schematically show the hydroponic cultivation tool according to the present invention, and are partially emphasized, enlarged, reduced, or omitted to deepen the understanding. In some cases, it does not accurately represent the scale or shape of the member. Furthermore, the various numerical values used in the description with reference to the drawings are only examples, and can be variously changed as necessary.

The hydroponic cultivation tool of the present invention includes a support member that supports and grows a plant, and a liquid supply means that is disposed in contact with the support member and supplies nutrient solution to the support member.
Drawing 1 is a mimetic diagram showing another embodiment of (a) hydroponics equipment concerning the present invention, and (b) hydroponics equipment. The hydroponic cultivation tool 10 includes a plant 11, a sponge 12 that supports and grows the plant, and a liquid supply means 13 that is arranged in contact with the sponge. Moreover, the hydroponic cultivation tool 20 includes a plant 21, a sponge 22 that supports and grows the plant, and a liquid supply unit 23 that is disposed in contact with the sponge.
The plants 11 and 21 may be plants that can be grown by hydroponics, and may be flowers such as various ornamental flowers and edible flowers, foliage plants, and vegetables such as lettuce and tomato.

The supporting member can be used without any particular limitation as long as it is used for hydroponics, but usually a porous material is used for plant roots to be stretched, specifically rock wool, foaming Phenol, foamed polyurethane, granule medium, etc. are used. In addition, when applied to a pipe hydroponics system to be described later and a hydroponic kit that installs hydroponic tools at the opening of the container, it is preferable that the material is deformable. A synthetic sponge made of resin is preferably used.
What is necessary is just to set the magnitude | size of a supporting member suitably according to the kind etc. of the plant to grow, and the shape is not specifically limited. Usually, it is 1 cm or more in the width direction and the height direction, preferably 5 cm or more, and usually 100 cm or less, preferably 30 cm or less. In this embodiment, since the support member and the liquid supply means are in contact with each other, the support member does not need to contact the liquid surface of the nutrient solution, and the length in the height direction may be relatively short. The shape of the support member is preferably a rectangular shape such as a cube or a rectangular parallelepiped in consideration of industrial mass production.

The liquid supply means 13 sucks up the nutrient solution by immersing one end in the nutrient solution in the lower part of the figure. Any material that can supply nutrient solution to the support member can be used without particular limitation, and examples thereof include non-woven fabric, urethane-based sponge, paper, and cotton. From the viewpoint of sucking up the nutrient solution smoothly, it is preferable to use a nonwoven fabric.
The length in the longitudinal direction of the liquid supply means 13, that is, the length in the height direction as shown in FIG. 1, must be longer than at least the length in the height direction of the support member, and is usually twice the height direction length of the support member. Above, preferably 3 times or more. What is necessary is just to set suitably the longitudinal direction length of the liquid supply means 13 so that it may be immersed in a nutrient solution by the scene where the hydroponic cultivation tool 10 is applied.

On the other hand, both ends of the liquid supply means 23 are in contact with the sponge 22, and the liquid supply means 23 is installed in a loop so as to include the sponge 22 and the root of the plant 21. By soaking the loop portion in the nutrient solution, the nutrient solution can be supplied to the sponge 22 from both ends of the fluid supply means 23.
Although the width direction length of the liquid supply means 13 and 23 is not particularly limited, it is preferably longer than ½ of the width direction of the support member from the viewpoint of smoothly supplying the nutrient solution to the support member. The width is preferably substantially the same as the width direction of the support member.

In the hydroponic cultivation tool 10 according to this embodiment, the sponge 12 and the liquid supply means 13 are fixed by a fixing member 14. The fixing method is not limited to a form using a fixing member, and may be fixed by a method such as winding around a supporting member without using a fixing member. What is necessary is just to select an appropriate fixing method according to the use, for example, when applying to a pipe hydroponic cultivation system, the sponge 12 and the liquid supply means 13 are not fixed by the flow of the nutrient solution flowing in the pipe. Need to be fixed. When a fixing member is used, a stapler, a tag gun, a fixing string, or the like is used as the fixing member. Examples of not using the fixing member include fixing by unevenness and fitting.
The sponge 12 and the liquid supply means 13 may be fixed at any location as long as the liquid supply means can secure the liquid supply capability, but is preferably fixed at the end of the liquid supply means. .
Similarly, the hydroponics tool 20 has the sponge 22 and the liquid supply means 23 fixed by the fixing member 24.

The hydroponic cultivation tool concerning this invention is used suitably for a pipe hydroponic cultivation system. FIG. 2 is a schematic diagram showing a general vertical multistage pipe hydroponic cultivation system.
The pipe hydroponic cultivation system 100 includes a plurality of plants 101, a multistage connected vinyl chloride pipe 102, a nutrient solution 103 stored in a water tank 106, a feed nozzle 104 that pumps the nutrient solution 103 and supplies the nutrient solution 103 to the connected vinyl chloride pipe 102, A drainage port 105 for discharging the nutrient solution from the vinyl pipe is provided. A pipe is not restricted to a vinyl chloride pipe, A ceramic pipe, an aluminum pipe, etc. can be used. The shape of the pipe is not limited to a cylindrical shape, and may be a prismatic pipe.
And in FIG. 3, the expansion schematic diagram of the location which installs a pot in a vinyl chloride pipe of the pipe hydroponic cultivation system using the pot filled with soil is shown.

In FIG. 3, the vinyl chloride pipe 102 has a plurality of openings indicated by alternate long and short dash lines in the drawing. In each opening, a pot 107 filled with soil 108 is installed, and the lower part of the pot is immersed in the nutrient solution 103, so that the nutrient solution is supplied to the plant root through the soil 108 filled in the pot 107. Is done.
In consideration of ease of replacement, the bowl 107 is generally arranged with a gap 109 between the opening of the pipe 102 and the bowl 107. Because of such a structure, the bowl 107 is installed outdoors. Has a problem that rainwater flows from the gap 109 and the nutrient solution is diluted.
In addition, in order to supply the nutrient solution 103 to the root of the plant 101 indicated by the dotted line in the figure, it is necessary to immerse the bottom of the pot in the nutrient solution, so that the size of the pot is increased to be larger than the inner diameter of the pipe. It is necessary to increase the flow rate of the nutrient solution and raise the level of the nutrient solution.

On the other hand, FIG. 4 is a schematic diagram showing a pipe hydroponic cultivation system using the hydroponic cultivation tool according to the embodiment of the present invention.
The pipe 202 has a plurality of openings indicated by alternate long and short dash lines in the drawing. A hydroponic cultivation tool 210 according to an embodiment of the present invention is installed in each opening.
The liquid supply means 213 included in the hydroponic cultivation tool 210 supplies the nutrient solution 203 to the sponge 212 by being immersed in the nutrient solution 203.
Unlike the pipe hydroponic system shown in FIG. 3, the hydroponic cultivation tool 210 according to the embodiment of the present invention has the liquid supply means 213, so that the liquid supply means 213 is provided even when the water level of the nutrient solution 203 is low. Since the nutrient solution 203 can be supplied to the sponge 212 if the end of the plant is immersed in the nutrient solution 203, even if the water level is low, the nutrient solution is not supplied to the plant root and the plant will die. There is no. The end of the liquid supply means may be immersed in the nutrient solution. However, when at least a part of the liquid supply means is in contact with the bottom surface of the pipe as in the case of the liquid supply means 213 ′, It is possible to reliably supply a large amount of nutrient solution.
Further, since the sponge 212 is made of urethane sponge or the like and has deformability, the sponge 212 can be installed without a gap between the opening of the pipe 202. Therefore, rainwater does not flow into the pipe and the nutrient solution is not greatly diluted.

On the other hand, FIG. 5 is an enlarged schematic view of a pipe connection portion with the lower stage at the end of each stage in the pipe hydroponic cultivation system.
In FIG. 5A, in which the upper pipe and the lower pipe are simply connected by a pipe extending in the vertical direction, the oxygen is deficient as the lateral length of the pipe is increased, and as the lower stage is reached. Therefore, the growth of the plant is worsened and in some cases it may wither.
Therefore, in a preferred embodiment of the present invention, as shown in FIG. 5 (b), the end of each stage pipe is opened, and air is passed through the opening, thereby deteriorating plant growth due to lack of oxygen. Can be prevented. Furthermore, it is preferable to install an insect repelling means such as a mesh 110 in the opening.

In addition, although not shown, by preparing three connection pipes at the connection part of the pipe, each serving as a port for receiving nutrient solution from the upstream direction, a port for feeding nutrient solution in the lower direction, and a vent port, Oxygen deficiency can be prevented. At that time, the venting opening is preferably opened upward from the pipe so as to prevent the nutrient solution from spilling, and is preferably inclined by 90 ° ± 45 ° with respect to the vertical direction of the pipe. . Similarly, it is preferable to install an insect repellent means such as a mesh in the opening.
It is also preferable to provide ventilation holes in the pipe at regular intervals against oxygen deficiency. The ventilation hole may be provided on the upper hemispherical surface of the pipe. By providing the ventilation hole above the water level of the nutrient solution, the ventilation can be reliably ensured without leakage of the nutrient solution.

The hydroponic cultivation tool according to the present invention can be used as a hydroponic cultivation kit by installing it at an opening of a container, for example, a drinking mouth of a plastic bottle, and FIG. 6 shows an embodiment of the present invention. The schematic diagram of the hydroponic cultivation kit 300 which installed the hydroponic cultivation tool which concerns on this in the container is shown.
The hydroponic cultivation kit 300 is configured such that the hydroponic cultivation tool 310 according to the embodiment of the present invention is installed in the opening of the container 320.
The container 320 can be used without particular limitation as long as it is a container having an opening. Examples thereof include a plastic bottle, an empty juice bottle, an empty milk bottle, a vase, and a cup. Not limited.
Since the support member of the hydroponic cultivation tool 310 according to the embodiment of the present invention is made of a deformable sponge or the like, it can be easily installed in the opening of the container.

When using as a hydroponics kit, a form in which one end of the liquid supply means 313 is fixed to the sponge 312 and the fertilizer 315 is held in a portion not fixed to the medium is preferable. By such a form, in the hydroponics kit using a container, the effort which replaces a nutrient solution for the supplement of nutrients can be saved. The place where the fertilizer is held in the liquid supply means 313 is preferably a position where the fertilizer is disposed at a position lower than the water level of the nutrient solution 303 in the container 320.
The fertilizer may be held in the liquid supply means in a solid state, or may be held in the liquid supply means in a state of being put in a bag.

FIG. 7 is a schematic top view showing another embodiment of the pipe hydroponic cultivation system of the present invention. 2 shows a vertical multistage pipe hydroponic cultivation system 100, the horizontal pipe hydroponic cultivation system 400 shown in FIG. 7 is low in installation cost, and compared with the vertical multistage type. Because there is no height, it is resistant to wind from the side.
The horizontal pipe hydroponics system 400 includes a plurality of vinyl chloride pipes 402 in which a plurality of plants 401 are arranged in parallel in the vertical direction of the figure. The number of plants arranged in one vinyl chloride pipe is not particularly limited, and a desired number may be arranged. Moreover, the space | interval between plants is not specifically limited. The number of the vinyl chloride pipes 402 is not particularly limited, and may be determined as appropriate according to the usable space.
In addition, the multi-stage pipe hydroponic cultivation system is not limited to one that forms steps in the vertical direction, and may be one that forms steps in the vertical oblique direction like a pyramid shape. When steps are set in the vertical oblique direction, steps may be set in two oblique directions from the apex to form a multi-stage type, or steps may be set only in one direction to form a multi-stage pipe hydroponic system.
