Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a hydroponic cultivation support and a hydroponic cultivation method using the same, and in particular, water of vegetables in which one strain germinates and grows from one species, such as “Tingen vegetables” and “salad vegetables”. The present invention relates to a hydroponic support and a hydroponic method suitable for plowing.
[0002]
[Prior art]
Hydroponics is a method of cultivating plant roots by directly immersing them in an aqueous solution. If water is available, it can be cultivated in areas unsuitable for agriculture and has the advantage of easy continuous cropping.
[0003]
Conventionally, this type of hydroponics has been performed by the following method.
That is, as shown in FIG. 15, the sponge plate 1 is formed in such a state that “+”-shaped cuts 3 are inserted at intervals of several centimeters like the vertical and horizontal grids and the block-shaped medium 5 is connected. A recess 7 is provided on the upper surface side of the culture medium 5 and a notch 9 is provided from the recess 7 to the lower side.
[0004]
Then, as shown in FIG. 16 (partially omitted in cross section), the sponge plate 1 is floated in a water storage tank 15 in which an aqueous solution (culture solution) 13 in which fertilizer is dissolved is stored and placed in the depression 7 of the medium 5. The roots 15 are germinated from the seeds 11 along the cuts 9 and spread into the aqueous solution 13.
[0005]
Thereafter, the individual culture media 5 are separated from the sponge plate 1 and, as shown in FIG. 17, the culture media 5 are fitted into the through holes 19 that are formed through the support plate 17 made of expanded polystyrene resin at predetermined intervals. The support plate 17 is floated on 15 or a suitable water tank for hydroponics, or the root 15 is appropriately supported in a state of being immersed in the aqueous solution 13, and cultivated in a greenhouse for a predetermined period, for example.
[0006]
Then, when the greening vegetables 21 grow in a edible state, the sponge medium 5 is extracted from the support plate 17 and the roots 15 entangled with the medium 5 are cut at the root and shipped.
[0007]
[Problems to be solved by the invention]
However, in the above-described hydroponics method, the seedlings 11 are placed on the medium 5 previously formed on the sponge plate 1 to germinate, and then the individual medium 5 is separated. Since each of the through holes 19 was fitted one by one, not only the operation of separating the culture medium 5 from the sponge plate 1 but also the individual culture media 5 with the germinated green beans 21 were fitted into the through holes 19 of the support plate 17 one by one. The work was extremely complicated and troublesome, the workability was not improved, and it was difficult to demonstrate the advantages of hydroponics productivity.
[0008]
Furthermore, when shipping the grown pongee vegetables 21, the medium 5 is removed from the support plate 17 one by one, and the root 15 entangled with the medium 5 is cut off from the pongee vegetables 21. Does not improve.
[0009]
Furthermore, it is necessary to discard the sponge medium 5 in which the roots 15 are entangled, and there is room for improvement from the viewpoint of environmental conservation.
[0010]
Therefore, the present inventor has recently completed the present invention, paying attention to the fact that a sheet material such as a nonwoven fabric has begun to be supplied in a state where seeds are held at predetermined intervals.
[0011]
The present invention has been made under such circumstances, and it is easy to place a germinated plant on a water storage tank for hydroponics, and it is easy to remove a grown plant, so that the cultivation efficiency is good. A support and a hydroponics method are provided.
[0012]

And a ramp that is formed toward the through hole to guide the water flow caused by the water spray.
[0013]
And in the hydroponic cultivation support tool of the present invention, a plurality of concave grooves formed at predetermined intervals on the upper surface side of the support plate body, on which tape-like seeded sheet members are placed. It is preferable to form the through hole and the oblique path in these concave grooves.
[0014]
Moreover, in the hydroponic cultivation support tool of the present invention, it is preferable to form a slope for guiding the water flow by watering to the concave groove on the top surface sandwiching the concave groove in the support plate body.
[0015]

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1, 2 and 3 are a plan view, a cross-sectional view, a bottom view and a side view showing an embodiment of a hydroponic cultivation support according to the present invention. In addition, about the hydroponic cultivation method which concerns on this invention, it shows in the process explaining the usage example of the support tool for hydroponic cultivation.
[0018]
1 to 3, a rectangular support plate main body 23 which is a main body of a hydroponics support tool is made of, for example, a foamed polystyrene resin plate having good water resistance and easy to float on water. , The upper surface side) has a plurality of concave grooves 25 having a width T formed in parallel at predetermined intervals.
[0019]
The support plate body 23 is formed with through holes 27 penetrating from the upper surface side to the lower surface side at regular intervals along the longitudinal direction in each concave groove 25, and in the middle between the through holes 27. A sloping road 29 having a downward slope toward both the through holes 27 is formed.
[0020]
That is, as shown in FIG. 3, the bottom surface of each concave groove 25 has a corrugated or sawtooth-shaped ramp 29 in which each through-hole 27 portion is a low portion and the middle between each through-hole 27 is a high portion. .
[0021]
As shown in the longitudinal sectional view of FIG. 4A and the perspective view of FIG. 4B, the through-hole 27 formed in the support plate body 23 overlaps and fastens known coarse nonwoven fabric tapes 31 and 33 to each other, The seed tape member 37 is formed by sandwiching the seed 35 of the green vegetables between the nonwoven fabric tapes 31 and 33 at a constant interval.
[0022]
The width T of each concave groove 25 of the support plate main body 23 is formed to be slightly wider than the width t of the seeded tape member 37, and the seeded tape member 37 is placed in the concave groove 25 along the longitudinal direction of each concave groove 25. It fits comfortably and the non-woven tape 31 or 33 overlaps.
[0023]
On the upper surface of the support plate main body 23, the adjacent grooves 25 are in a protruding state protruding between the adjacent grooves 25, and as shown in FIG. 1B, the top surface 39 has a groove between the adjacent grooves 25. A slope 41 that protrudes in a mountain shape along 25 and goes down to both adjacent grooves 25 is formed. FIG. 5 is a perspective view showing the support plate main body 23.
[0024]
Next, a usage example of the support for hydroponics according to the present invention configured as described above will be described.
[0025]
First, as shown in FIG. 4, a seeded tape member 37 is prepared, which holds the seedlings seed 35, for example, at regular intervals between the non-woven tapes 31 and 33. Cut into lengths and place them in parallel.
[0026]
In order to arrange the cut seeded tape members 37 in parallel, although not shown, there are, for example, a technique in which the seeded tape members 37 are arranged so as to be passed between opposing sides of a rectangular frame body and fastened with pins or the like.
[0027]
Then, water is sprayed on a plurality of seeded tape members 37 arranged on a frame or the like, and it is floated on a water storage tank (not shown), and seeds 35 are germinated as shown in FIG. Reference numeral 43 in FIG. 7 is a germinated tangy green and reference numeral 45 is a root.
[0028]
After that, as shown in FIG. 8, the seeded tape members 37 having been sprouted are placed on the support plate main body 23 shown in FIG.
[0029]
In this case, the germinated green beans 43 and roots 45 are placed so as to overlap each through-hole 27, but it is not necessary to put the root 45 into each through-hole 27. As shown in FIG. What is necessary is just to position together with the hole 27.
[0030]
The placed seeded tape member 37 floats in the vicinity of each through hole 27, and a gap S is easily formed between the through hole 27 and the opening.
[0031]
Note that the seeded tape member 37 housed in each concave groove 25 may be stopped with pins or the like (not shown) at both ends of each concave groove 25 in a taut state.
[0032]
Thereafter, as shown in FIG. 10 (partially shown in a side view), the aqueous solution so that the lower surface of the support plate body 23 is immersed in a water storage tank 49 in which an aqueous solution 47 in which a known hydroponics fertilizer is dissolved is stored. 47 or is supported by a step portion (not shown) of the water storage tank 49.
[0033]
Then, as shown in FIG. 11, water is sprayed from the upper surface side of the support plate body 23 by the watering device 51.
[0034]
Then, the water that has poured into the concave grooves 25 out of the water hung on the upper surface of the support plate main body 23 by this watering, the bottom surface of each concave groove 25 becomes a corrugated or sawtooth-shaped ramp 29, Since the slope 27 is low in the hole 27 portion and high in the middle between the through holes 27, the slope 29 flows into each through hole 27 as a water flow toward each through hole 27.
[0035]
The water that has poured onto the top surface 39 between the adjacent grooves 25 has a slope 41 that descends to both the adjacent grooves 25, so that the water flows toward the adjacent grooves 25. It flows into each concave groove 25 and flows into each through-hole 27 directly or via a ramp 29.
[0036]
Then, in the process of water flowing into each through hole 27, as shown by the broken line in FIG. 9, the root 45 is automatically guided to each through hole 27 so as to flow to each through hole 27 by the water flow, and thereafter Is extended by water nutrients from the aqueous solution 47 of the water tank 49, and the tangy vegetables 43 are grown.
[0037]
It should be noted that water spraying to the support plate main body 23 may be performed for a short time, for example, about 20 to 30 minutes, depending on the amount of water, as long as the root 45 enters each through hole 27.
[0038]
Thereafter, when the green vegetables 43 are grown in a state suitable for commercialization, the individual tape members 37 are removed from the support plate body 23 as shown in FIG.
[0039]
Since each through-hole 27 of the support plate main body 23 has a much larger diameter than the root 45 and has play, simply lifting the tape member 37 can easily remove the green vegetables 43 and the root 45 attached thereto.
[0040]
Then, the green vegetables 43 are cut from the tape members 37 with the green vegetables 43 and the roots 45 and shipped as products.
[0041]
If the tape member 37 is formed of natural paper fiber or easily corroded fiber, the tape member 37 having the root 45 attached by cutting the greening vegetables 43 can be disposed of as garbage.
[0042]
By the way, in the structure mentioned above, each concave groove 25 has a slant path 29 with each through-hole 27 portion as a low portion and a middle portion between each through-hole 27 as a high portion, and a seeded tape in the vicinity of each through-hole 27. A gap S is formed between the member 37 and the opening of the through hole 27, and the root 45 is easily flowed to the through hole 27 by the water flow in the gap S portion. The support is not limited to this.
[0043]
For example, as shown in FIG. 13, when the protrusion 53 is partially formed in the concave groove 25, that is, around the through hole 27 on the upper surface side of the support plate main body 23, the seeded tape member 37 and the through hole 27 are opened. Formation of the space S between the mouth becomes more reliable, and the root 45 can be reliably inserted into each through hole 27. In addition, the shape of the protrusion part 53 is arbitrary.
[0044]
Further, the inclined surface 41 formed on the top surface 39 between the adjacent concave grooves 25 is not limited to the above-described example. For example, as shown in FIG. It may also be a divided slope 55 that forms a water flow to the higher part.
[0045]
When such a divided slope 55 is provided, the water flow from the direction between the adjacent through holes 27 increases and becomes strong, and the root 45 can be reliably inserted into each through hole 27.
[0046]
By the way, the support for hydroponics according to the present invention is not necessarily limited to the configuration in which the concave groove 25 is provided and the through hole 27 is formed.
[0047]
Although not shown, for example, a simple plate-like support plate body in which the concave groove 25 is omitted is formed with through holes at a predetermined interval, and an oblique path is formed around the through hole to form a water flow by sprinkling toward the through hole. Even if it exists, the objective of this invention can be achieved.
[0048]
In the configuration using a simple plate-like support plate main body plate in which the concave groove 25 is omitted, not only the seeded tape member 37 but also a seeded sheet member in which seeds are arranged at a predetermined interval on a wide sheet material. The shape may be selected according to the support plate body plate. In the present invention, the band shape of the sheet material is considered as the tape material.
[0049]
