Description

  The present invention relates to a plant cultivation rack that can be easily grown using a container for plant cultivation.

  When plant cultivation is performed by three-dimensionally supporting a container for plant cultivation on a rack shelf, it is necessary to efficiently illuminate the plant planted in the container. That is, lighting fixtures must be incorporated in this type of plant cultivation rack. However, this type of conventionally known rack, for example, as described in Japanese Patent Application Laid-Open No. H10-228707, has a light beam on the upper side of the rack shelf. Arrange the lighting fixtures with the reflectors in an appropriate arrangement, or provide each of the lighting fixtures with a large light reflector common to a plurality of lighting fixtures without providing the light reflector, A lighting fixture was attached to the side.

JP 2008-245554 A

  In the conventional plant cultivation rack as described above, in order to enhance the lighting effect on the plant cultivation space on the upper side of the plant cultivation container placed on the shelf, only the light reflector is disposed on the upper side of the lighting fixture. In addition, it is necessary to provide an enclosure means that the light reflector surrounds the plant cultivation space, and to place the light source of the lighting fixture inside the enclosure means. However, even when a fluorescent lamp type with a small calorific value is used as the light source of the lighting fixture, a temperature rise inside the enclosure means is unavoidable, and a thermal adverse effect on the cultivated plant occurs. In addition, the static atmosphere surrounding the cultivated plant also has a negative effect on the growth of the plant.

  The present invention proposes a plant cultivation rack capable of solving the conventional problems as described above, and the plant cultivation rack according to the present invention according to claim 1 is an embodiment described later. When the reference symbol used in the description of FIG. 1 is attached, it is a rack including a shelf 11 on which a plurality of cultivation containers 1 are placed in the depth direction so as to be freely put in and out of the depth direction. Enclosed means 23 that surrounds at least the upper region of the long plant cultivation space and whose inner surface is a light reflecting surface is disposed, and this enclosure means 23 is a ceiling-side light reflector that covers the ceiling of the plant cultivation space. 18 and front and rear vertical light reflectors 19 and 20 covering both front and rear sides in the depth direction of the plant cultivation space, and the light source (fluorescent tube 17a) of the lighting fixture 17 is disposed inside the enclosure means 23. As well as At one end in the frontage direction of the plant cultivation space surrounded by the enclosure means 23, a blower fan 24 for blowing air toward the other end side in the frontage direction of the plant cultivation space is disposed, and both the front and rear vertical light reflections are performed. Of the plates 19 and 20, the vertical light reflecting plate 19 on the side where the cultivation container 1 is taken in and out is configured to be openable and closable.

  As a rack of the present invention, a rack in which the cultivation containers 1 are placed in a row in the depth direction along the frontage direction on the shelf 11, or a cultivation container 1 in the front and rear rows in the depth direction along the frontage direction on the shelf 11 is provided. The rack to be placed is included, but in any case, the cultivation container 1 is configured so as to be able to be put in and out only on one side of the shelf 11 in the depth direction, or on either side of the shelf 11 in the depth direction. The cultivation container 1 is also configured to be freely put in and out. Therefore, when the cultivation container 1 is configured to be freely put in and out only on one side of the shelf 11 in the depth direction, as described in claim 2, the front and rear vertical light reflectors 19 and 20, When the vertical light reflector 20 on the side opposite to the cultivation container loading / unloading side can be fixed, and the cultivation container 1 can be freely loaded and unloaded on either side of the shelf 11 in the depth direction. As described in claim 3, both the front and rear vertical light reflectors 19 and 20 may be configured to be openable and closable. Moreover, it is a rack in which the cultivation containers 1 are placed in two rows in the depth direction along the frontage direction on the shelf 11, and as described in claim 3, the front and rear vertical light reflecting plates 19, 20 are When both are configured to be openable and closable, it is also possible to add a fixed vertical light reflecting plate so as to partition the middle of the placement region of the two rows of cultivation containers 1 before and after the depth direction.

  When practicing the present invention according to any one of claims 1 to 3, as described in claim 4, the enclosure means 23 includes a lateral vertical light reflector that covers both ends of the plant cultivation space in the frontage direction. 21 and 22 can be provided. When the horizontal side vertical light reflection plates 21 and 22 are provided, the vertical light reflection plate on the blowing direction side of the blowing fan 24 among the horizontal side vertical light reflection plates 21 and 22 according to claim 5. 22 can be provided with an air circulation port 25. Furthermore, as described in claim 6, the air circulation port 25 is formed in a horizontally long slit shape, and a flap 25a extending obliquely downward inside the enclosure means 23 can be projected from the upper side thereof.

  In addition, as described in claim 7, the surrounding means 23 can be configured such that only the upper region of the plant cultivation space is open and the lower periphery is open.

  According to the structure of this invention of Claims 1-3, the cultivated plant in the container for cultivation mounted in the shelf is not only illuminated by the direct light from the light source of the lighting fixture above it, but also the surrounding means Since it is illuminated also by the reflected light beam reflected from the ceiling side light reflecting plate and the vertical light reflecting plate, the illuminance on the cultivation container can be greatly increased and plants can be efficiently cultivated. Moreover, even if the enclosure space by the enclosure means is deepened to increase the illumination efficiency, the other end of the space surrounded by the enclosure means in the direction of the shelf front is blown by the blower fan on one end side. Since the airflow that flows toward the side can be generated, it is possible to prevent the ambient temperature in the enclosure space from being increased by the enclosure means incorporating the light source and to prevent the atmosphere having the increased temperature from being stationary. And can grow well. Of course, when the container for cultivation is taken in and out of the shelf, the vertical light reflecting plate on the side for taking in and out can be opened, so that the container for cultivation can be taken in and out without any trouble.

  In addition, according to the structure of Claim 4, the whole circumference | surroundings of at least the upper area | region of the plant cultivation space long in the frontage direction above a shelf are completely enclosed, and the cultivation effect by illumination is further improved and illumination efficiency is improved. It can be further enhanced. At this time, according to the configuration of claim 5, the air flow generated by the blower fan in the space long in the direction of the shelf front completely surrounded by the surrounding means is completely flowed to the end, and the end portion In this way, it is possible to prevent an adverse effect caused by the retention of air. Furthermore, according to the structure of Claim 6, it can prevent that the reflective efficiency of the horizontal side vertical light reflection board provided with the air circulation port falls by presence of an air circulation port.

  In addition, when installing the rack by this invention in the air-conditioned room and performing plant cultivation, according to the structure of Claim 7, the air current by the fan for ventilation in the space enclosed by the said enclosure means With the occurrence of, it is possible to flow the air-conditioned room atmosphere around the rack into the plant cultivation space on the upper side of the container for cultivation, rather than the case where the plant cultivation space is a completely sealed space, The growth of cultivated plants can be improved. In addition, regardless of the presence or absence of the vertical light reflector, the state of the cultivated plant can be observed to some extent from the entire periphery of the shelf, which is convenient for management.

It is a disassembled perspective view of the principal part which shows the outline of another Example of this invention.

  First, the container for soil cultivation used in the rack of the present invention will be described with reference to FIGS. 1 to 3. The container for soil cultivation 1 includes a container body 2 having a rectangular planar shape, Planted in the irrigation pipe 3 placed on the inner bottom surface 2a, the plant cultivation soil layer 4 made of soil filled in a required amount in the container body 2 from above the irrigation pipe 3, and the plant cultivation soil layer 4 It is composed of a plurality of light reflecting sheets 5 covering the surface of the plant cultivation soil layer 4 around the cultivated plant seedling 5.

  As the container body 2, a synthetic resin container for storing goods or transporting can be used as it is, and the size is not particularly limited, but a plant cultivation environment using a rack as will be described later. In consideration of the case where the interior is configured indoors, a long side length: about 700 mm, a short side direction length: about 460 mm, a height: about 120 mm (height from the inner bottom surface 2a: about 112 mm) was adopted. As the irrigation pipe 3, for example, a water-permeable flexible pipe made of porous rubber and in which water oozes out from the entire surface can be used. The irrigation pipe 3 is disposed on the inner bottom surface 2 a of the container body 2. Next, it is bent and placed in an annular shape so as to be separated from the peripheral wall of the container body 2 by a substantially constant distance, and one end of the irrigation pipe 3 is guided to one corner of the container body 2 and bent upward. A water receiving end 3a projecting vertically upward from the container body 2 is formed, and the other end opening located on the inner bottom surface 2a of the container body 2 is closed by fitting and fixing the cap 3b. As the soil constituting the soil layer 4 for plant cultivation, for example, a soil known as a non-chemical environmental material for soil, such as “bentonite” coated on “peat moss”, which is a general soil improvement material, can be used. Such a soil was filled so that the set-up height from the inner bottom surface 2a of the container body 2 to the surface of the soil layer 4 for plant cultivation (a flat surface before forming a ridge as shown in the figure) was about 80 mm. . As the light reflecting sheet 5, for example, a light reflecting sheet made of ultrafine foamed polyethylene terephthalate can be used.

  In the illustrated example, a plurality of ridges 4a parallel to the container body short side direction are formed on the surface of the plant cultivation soil layer 4 at appropriate intervals in the container body long side direction, and each ridge 4a is appropriately arranged in the cocoon length direction. The seedlings 6 of cultivated plants (small leafy vegetables) are planted at intervals, and the width between the ridges 4a and the outside of the ridges 4a at both ends is a band that is long in the direction of the short side of the container body and is suitably narrower than the interval between the minimum ridges. A plurality of light reflecting sheets 5 cut into a band having a prescribed size are laid with the light reflecting surface facing up so as to cover the surface of the soil layer 4 for plant cultivation. Depending on the type of cultivated plant, the number of juts 4a formed in parallel decreases and the spacing between the coffins 4a widens. Therefore, when only the light reflecting sheet 5 having the specified size is used, 2 between the coffins 4a. The light reflecting sheets 5 can be laid so as to partially overlap each other. Of course, in actual planting, it is also possible to use the light reflecting sheet 5 cut according to the interval between the ridges 4a at that time. In addition, what is necessary is just to form the basket 4a according to a cultivation plant, and when the basket 4a is unnecessary, what is necessary is just to finish the surface of the soil layer 4 for plant cultivation flat.

  Next, the cultivation rack of the present invention that supports the above-described soil cultivation container 1 will be described with reference to FIGS. 4 to 8. The figure shows only the intermediate two-stage shelf 11 of the rack 10. Even in the case of a rack having more than one shelf, the configuration of each shelf is the same as that shown in the figure. The rack 10 includes support members 12 whose lower ends and upper ends are connected to each other by connecting frames at four corners thereof, and the shelves 11 of each step are installed between a pair of support members 12 in the rack depth direction. The shelf 11 shown in the figure is supported by a pair of left and right shelf holders 13 in which a plurality (four in the illustrated example) of beam members 14 parallel to the rack opening direction are arranged in parallel at appropriate intervals in the rack depth direction. Thus, each beam member 14 is supported by a beam member fitting support portion formed on the shelf support 13 at both ends thereof. Of course, the shelf 11 is not limited to the one having the above-described configuration, and the entire surface is constituted by a single plate material, the one constituted by a plurality of strip-like plates before and after the rack depth direction, and parallel to the rack frontage direction. Various conventionally well-known shelves, such as a structure in which a sub beam material parallel to the rack depth direction is installed between the pair of front and rear beam materials at appropriate intervals in the rack front-end direction, can be used.

  On each shelf 11, a plurality of (three in the illustrated example) parallel arrangements of the containers 1 for soil cultivation in the above-described configuration are arranged in the rack front direction with the container body long side direction being parallel to the rack depth direction. Supported. At this time, the rack 10 is configured in such a size that both the front and rear ends in the long side direction of each container main body 2 can be accommodated between the pair of column members 12 before and after the rack depth direction when the rack 10 is viewed from the side. Of the plurality of beam members 14 to be configured, the beam members 14 at the front and rear ends in the depth direction are configured to enter slightly inside the front and rear ends in the long side direction of the container 1 to be supported. Thus, the shelf 11 of each stage is provided with a guide roller 15 on the front side (side where the container 1 is put in and out) and a stopper 16 for preventing container drop on the back side. The guide roller 15 is a roller disposed between the pair of left and right support members 12 on the front side of the rack 10 and oriented in parallel to the rack front direction, and the bearing members at both ends thereof are attached to the pair of left and right shelf supports 13. Yes. Thus, the guide roller 15 protrudes slightly forward from the front end of the container 1 supported by the shelf 11 and slightly above the container support height of the shelf 11 (the upper surface height of the beam member 14). It projects so as to prevent the container body 2 from sliding out to the front side. The container drop prevention stopper 16 is composed of a rod-shaped member disposed between the pair of left and right support columns 12 on the rear side of the rack 10 and oriented parallel to the rack front direction, and is positioned at a position higher than the container support height of the shelf 11. Both ends are attached to a pair of left and right shelf supports 13.

  A lighting fixture 17 is attached above the soil cultivation container 1 supported by the shelf 11 of each stage using the ceiling frame of the shelf 11 or the rack 10 positioned directly above the container 1 for soil cultivation. It has been. The lighting fixture 17 may be a rod-like or annular fluorescent lamp, a bulb-type fluorescent lamp, or any other one, but a fluorescent lighting fixture specialized for plant cultivation is particularly desirable. In this illustrated example, a rod-like fluorescent lamp for plant cultivation is used as the lighting fixture 17, and a plurality of lighting fixtures 17 arranged in parallel in the rack depth direction are arranged such that the fluorescent tubes 17 a are parallel to the rack frontage direction and the lower side. It is attached to the lower side of the shelf 11 (or the ceiling frame) so as to illuminate the cultivated plant planted in the soil cultivation container 1. Specifically, the lighting fixture 17 attached to the lower side of the shelf 11 having the above-described configuration has the main body 17b of the lighting fixture 17 attached to the lower side of the beam member 14 constituting the shelf 11.

  The ceiling side light reflecting plate 18 is horizontally stretched so as to pass between the main body 17b of each lighting fixture 17 and the fluorescent tube 17a attached as described above. The ceiling-side light reflection plate 18 has a width in the rack depth direction that is substantially the same as a width in the depth direction of the rack 10 (interval between the outer surfaces of the pair of front and rear support column members 12). The distance between the inner side surfaces of the pair of left and right support members 12 in the front-end direction of the rack 10 is substantially the same, and is attached to the main body 17b of each lighting fixture 17 with the light reflecting surface facing down. Furthermore, the front side vertical light reflection plate 19, the rear side vertical light reflection plate 20, and the side light reflection plates 21, 22 that hang vertically are respectively provided on both the front and rear sides and the left and right sides of the ceiling side light reflection plate 18. The upper region (substantially above the plant cultivation space higher than the height of the cultivated plant at the time of harvesting), that is, the plant cultivation space on the upper side of the container 1 supported by the shelves 11 and connected in a direction in which the light reflecting surfaces face each other. The half portion is covered with the surrounding means 23 formed by the light reflecting plates 18 to 22 and the entire inner surface is a light reflecting surface. Therefore, the fluorescent tubes 17a of all the lighting fixtures 17 are arranged directly below the ceiling side light reflection plate 18 inside the enclosure means 23.

  Among the light reflecting plates constituting the enclosure means 23, at least the front vertical light reflecting plate 19 for putting in and out the soil cultivation container 1 is hinged or cloth-like instead of the front side of the ceiling side light reflecting plate 18. It is attached via a connecting material (such as gummed tape) so that it can swing up and down. In addition, a fan 24 is disposed on one end of the space surrounded by the enclosure 23 in the rack front direction, for example, on the inner side of the lateral light reflecting plate 21, and the opposite lateral light reflecting plate 22 includes As shown in FIG. 1A and FIG. 8, a required number of horizontally elongated slit-like air circulation ports 25 each having a flap 25 a extending obliquely downward inward from the upper side are provided. The flap 25a may be extended obliquely downward to the outside, or the flap 25a may be omitted, contrary to the illustration. Further, when the flap 25a is extended obliquely downward inward as shown in the drawing, the amount of light reflected to the inner side of the light reflecting plate 22 due to the presence of the air circulation port 25 is larger than in the case of extending obliquely downward outward. Decrease can be suppressed.

  Further, as shown in FIGS. 6 and 7, the rack 10 is provided with an independent water supply means 26 for each shelf 11. Each of the water supply means 26 includes a water supply pipe 27 installed horizontally below the ceiling-side light reflecting plate 18 of the surrounding means 23 provided above the shelf 11 of each stage and in the vicinity of the front side, and the water supply pipe 27. A branch pipe 28 that branches downward at a right angle from a position corresponding to each soil cultivation container 1, a stop cock 29 connected to the branch pipe 28, one end of which is detachably connected to each stop cock 29 and A flow rate is supplied to one end of the water supply pipe 27 and the flexible pipe 30 detachably connected to the water receiving end 3 a of the irrigation pipe 3 in each soil cultivation container 1 whose other end is located below the stop cock 29. It consists of a water supply tank 32 connected via a regulating valve 31. The other end of the water supply pipe 27 is closed by a cap 33.

  The water supply tank 32 is attached to the outside of the front end of the rack 10 at a position higher than the water supply pipe 27, and is configured so that it can be detached from the rack 10 by disconnecting from the water supply pipe 27 when replenishing water. However, the upper side is opened for water supply (a lid may be provided if necessary), and when the water level in the water supply tank 32 falls below a certain level, it is possible to use a hose connected to the water supply. It can comprise so that water can be replenished by work. Of course, in the case of a large-scale facility in which a large number of racks 10 having the above-described configuration are installed, a water level detection sensor is attached to each water supply tank 32 and a water supply pipe connected to the water supply for each water supply tank 32. Is connected via an automatic opening / closing valve, and when the water level detection sensor detects that the water level in the water supply tank 32 has fallen below the lower limit level, the water supply pipe connected to the water supply tank 32 is automatically opened and closed. All the water tanks are configured to close the automatic opening / closing valve when the valve is opened and the water level detection sensor detects that the water level in the water tank 32 has reached the upper limit level as a result of water supply. It is also possible to configure so that water supply to 32 is performed fully automatically.

  Next, a method of using the soil cultivation apparatus configured as described above will be described. The soil cultivation container 1 that has been completed by planting the seedlings 6 of the cultivation plant in the manner described above is used for each stage of the rack 10. A predetermined number is placed in parallel on the shelf 11 so that the long side direction of the container body is parallel to the rack depth direction. At this time, the front-side vertical light reflection plate 19 of the enclosure means 23 is opened to the upper front side. A means for holding the front vertical light reflecting plate 19 in an open state, for example, a tip hook portion of a hanging tool such as a chain or a string is provided in a locked hole provided near the lower side of the front vertical light reflecting plate 19. It is desirable to use simple holding means that can be engaged together.

  On the other hand, the stop cocks 29 of the water supply means 26 provided on each shelf 11 of the rack 10 are closed, and the water supply tank 32 is replenished with a required amount of water. In this state, the flexible pipe that hangs down from the water supply pipe 27 of the water supply means 26 provided in the shelf 11 on which the soil cultivation container 1 is placed at the water receiving end 3a of the irrigation pipe 3 in each soil cultivation container 1 Connect the tip of 30 and open the stop cock 29. As a result, water is automatically supplied from the water supply tank 32 to the irrigation pipe 3 in the soil cultivation container 1, and the irrigation pipe is generated by the position head energy of the amount of water in the water supply path from the water supply tank 32 to the irrigation pipe 3. As described above, water spreads from the periphery of the irrigation pipe 3 to the whole plant cultivation soil layer 4 by capillary action or the like. The whole can be maintained in a moist state with the required humidity.

  At this time, the surface of the plant cultivation soil layer 4 is covered with the light reflecting sheet 5 except for the periphery of the roots of the seedlings 6, so that the moisture transpiration from the surface of the plant cultivation soil layer 4 is extremely small. Therefore, the irrigation pipe 3 is used so that the humidity of the plant cultivation soil layer 4 gradually increases with time, moisture does not stay at the bottom of the plant cultivation soil layer 4, and the retention amount of the moisture does not gradually increase. The amount of water exudation per unit time from the water supply tank 32 can be set by the flow rate adjustment valve 31 on the side of the water supply tank 32. Basically, the amount of water in the water supply channel from the irrigation pipe 3 depends on the position head energy. Since the amount of moisture exudation per unit time is determined, by setting the position head energy in advance according to the capacity of the water supply tank 32 and the height relative to the water supply pipe 27, the plant cultivation soil layer 4 becomes excessively humid as described above. Can be prevented.

  While operating the water supply means 26 as mentioned above, it supplies with electricity to the lighting fixture 17 with which each shelf 11 is equipped, and the fluorescent tube 17a is lighted. As a result, the cultivated plant space on the lower side of the enclosing means 23 is not only from the direct light from the fluorescent tube 17a but also from the light reflecting surface (the light reflecting surfaces of the light reflecting plates 18 to 22) on the entire inner surface of the enclosing means 23. Illuminated by the reflected light and the reflected light from the light reflecting sheet 5 covering the plant cultivation soil layer 4. That is, the entire periphery of the cultivated plant seedling 6 including the leaf back side of the cultivated plant seedling 6 can be illuminated with a necessary illuminance.

  In the inner space of the enclosure means 23, the inner space is open only on the lower side, and a large number of fluorescent tubes 17a in the vicinity of the ceiling of the inner space are turned on. Temperature rise is considered. However, by energizing the blower fan 24 and blowing it with a very weak wind force from the end of the rack opening direction (longitudinal direction) inside the enclosure means 23 slightly obliquely upward, it is opposite to the blower fan 24. In connection with the presence of the air circulation port 25, a very weak air flow in the longitudinal direction can be generated in the inner space of the enclosure means 23, and this air flow causes air to flow between the inner space and the outside of the enclosure means 23. Can be generated. As a result, it is possible to prevent high temperature air from staying in the inner space of the enclosure means 23 and adversely affect the seedling 6 of the lower cultivated plant, and the atmosphere around the cultivated plant seedling 6 is maintained. It is possible to prevent the stationary. Of course, since the periphery of the seedling 6 of the cultivated plant between the enclosure means 23 and the soil cultivation container 1 is open, the atmosphere adjusted by the air conditioner in the plant cultivation room where the rack 10 is installed is Since air flows into the plant cultivation space on the upper side of the soil cultivation container 1 along with the air flow generated in the inner space of the enclosure means 23, the air around the seedlings 6 of the cultivation plant also stays stationary in this respect. There is no.

  As described above, the interior of the plant cultivation soil layer 4 is always kept in a moist state at an appropriate humidity according to the properties of the soil constituting the plant cultivation soil layer 4 and the type and degree of growth of the cultivated plant. Set the lighting time and illuminance per day, and also set the energizing time and wind power per day of the blower fan 24, and planted in the soil layer 4 for plant cultivation of each soil cultivation container 1 By growing the plant seedling 6, it is possible to grow the seedling 6 of the cultivated plant well during the required period and reach the harvest season.

  When harvesting a cultivated plant, the stop cock 29 of the water supply means 26 connected to the irrigation pipe 3 of the container 1 for soil cultivation is targeted, and the flexible pipe 30 is received by the irrigation pipe 3. The soil-cultivating container 1 to be harvested is pulled out from the top of the shelf 11 with the front vertical light reflecting plate 19 of the enclosure means 23 being lifted up and opened, and at this time, Since the guide roller 15 is slightly high, it is transferred onto the guide roller 15 so as to lift the front side of the soil cultivation container 1 to be pulled out. By pulling out the soil cultivation container 1 in this state, the soil cultivation container 1 to be harvested can be taken out from the shelf 11 lightly and smoothly using the rolling of the guide roller 15. Further, among the beam members 14 constituting the shelf 11, the beam member 14 on the front side recedes from the front side of the ceiling side light reflection plate 18 of the enclosure means 23 provided in the shelf 11 directly below, but this enclosure The guide roller 15 is disposed immediately above the front side of the ceiling side light reflector 18 of the means 23, and the soil cultivation container 1 to be taken in and out of the shelf 11 is provided with the enclosure 11 provided immediately below the shelf 11. It is possible to prevent the guide roller 15 from colliding with the front side of the ceiling side light reflector 18.

  In the above embodiment, since the water stop cock 29 is provided in the branch pipe 28 branched from the water supply pipe 27, the flexible pipe 30 is used for irrigation even when the water stop cock 29 is switched to the water stop state. When the pipe 3 is removed from the water receiving end 3a, the water in the flexible pipe 30 flows out. The same is true even if the flexible pipe 30 is removed from the stop cock 29 side. Therefore, on the premise that the flexible pipe 30 is removed from the water receiving end 3 a of the irrigation pipe 3, a stop cock 29 is provided at the tip of the flexible pipe 30 connected to the water receiving end 3 a of the irrigation pipe 3. It is desirable to have it. The stop cock 29 may be of a type that is manually operated to stop water. However, when the stop cock 29 is provided at the tip of the branch pipe 28 and when the stop cock 29 is provided at the tip of the flexible pipe 30. In either case, as a means for detachably connecting the water stop cock 29 and the flexible pipe 30 or the flexible pipe 30 and the water receiving end 3a of the irrigation pipe 3, one of the one-touch couplers for connecting the watering hose (plug) Or a socket), which uses a one-touch coupler with a built-in water stop valve that has a built-in water shut-off valve that automatically shuts off when the one-touch coupler is removed. It is most desirable to connect the branch pipe 28 and the flexible pipe 30 or connect the flexible pipe 30 and the water receiving end 3a of the irrigation pipe 3 with the built-in water stop valve on the flexible pipe 30 side. It is an embodiment.

  In the above-described embodiment, the surrounding means 23 disposed on the upper side of the shelf 11 is a vertical line that extends downward from the entire peripheral side of the ceiling-side light reflector 18 above the light source (fluorescent tube 17a) of the lighting fixture 17. Although the vertical width (height) of the light reflection plates 19 to 22 is set to a size that surrounds only the upper region of the plant cultivation space on the upper side of the shelf 11 (upper side of the placed soil cultivation container 1), Since the blower fan 24 is provided at one end in the lengthwise direction of the space surrounded by the surrounding means 23, as shown in FIG. 9, the vertical width (height) of each of the vertical light reflecting plates 19 to 22 is set. The space above the shelf 11 (the space between the upper shelf 11 or the upper end frame of the rack 10) can also be sized to enclose the entire height. In this case, the vertical light reflection plates 20 to 22 except for the openable front-side vertical light reflection plate 19 may be long so as to continuously block the space between the upper and lower shelves. Of course, the essential light reflecting plates in the present invention are the ceiling side light reflecting plate 18 and the front and rear vertical light reflecting plates 19 and 20, so that the side vertical light reflecting plates 21 and 22 can be eliminated.

  Furthermore, in the said Example, although the rack 10 by which the container 1 for cultivation was mounted in the depth direction along the frontage direction on the shelf 11 was shown, the two racks 10 of the said Example were piled up back to back and integrated. 10, that is, a rack 35 having a wide shelf 34 configured by arranging the shelves 11 in two rows in the depth direction, as shown in FIG. The soil cultivation container 1 is configured to be placed in two rows before and after the depth direction along the frontage direction of the shelf 34, and the soil cultivation container 1 can be taken in and out from either side of the shelf 34 in the depth direction. In the case of the rack 35 configured as described above, the enclosure means 36 disposed on the upper side of the wide shelf 34 has a wide ceiling that covers the ceiling of the plant cultivation space on the upper side of the wide shelf 34. Side light reflector 37 and the plant Front and rear vertical light reflectors 38 and 39 covering both front and rear sides in the depth direction of the cultivation space, and lateral vertical light reflectors 40 and 41 covering both ends of the plant cultivation space provided as needed. Although the soil cultivation container 1 is put in and out from either the front or back side of the shelf 34 in the depth direction, both the front and rear vertical light reflectors 38 and 39 are used as the front vertical light shown in the previous embodiment. It is necessary to be configured to be openable and closable like the reflector 19. Furthermore, in this case, an intermediate vertical light reflector 42 can be added along the frontage direction so as to partition the middle positions of the two rows of soil cultivation cultivation containers 1 along the frontage direction along the frontage direction of the shelf 34.

  Of course, even if the rack 35 is configured so that the soil cultivation container 1 can be placed in two rows before and after the depth direction along the frontage direction of the shelf 34 as described above, the rack 35 is placed in two rows before and after the depth direction. When all the placed soil cultivation containers 1 are taken in and out only from the front side of the shelf 34, only the front vertical light reflection plate 38 is configured to be openable and closable, and the rear vertical light reflection plate 39 is fixed. be able to. Also in the embodiment shown in FIG. 10, the vertical width (height) of each of the vertical light reflectors 38 to 42 is set to the space above the shelf 34 (the upper shelf 34 or the upper frame of the rack 35). It is also possible to have a size that can enclose the entire height of the space.

  Further, the rack 35 having the wide shelf 34 shown in FIG. 10 is formed by integrating two racks 10 each having the narrow shelf 11 back to back, so that the ceiling side light reflection plate 37 and The horizontal vertical light reflection plates 40 and 41 are each constituted by two light reflection plates 37a, 37b, 40a, 40b, 41a, and 41b in the depth direction of the shelf 34. The vertical light reflecting plates 40 and 41 can also be configured by a single wide light reflecting plate corresponding to the width of the shelf 34. Of course, the present invention can also be applied to a rack having a wide shelf 34 that is configured by expanding the width in the depth direction of the shelf 11 of the previous embodiment twice.

  The plant cultivation rack of the present invention uses a plant cultivation container such as a soil cultivation container filled with soil for plant cultivation, and is used as a relatively large plant in a room, not in the open ground, especially in a relatively large plant. It can be effectively used as a means to grow small leafy vegetables in a short cycle.
