Moreover, the nutrient solution storage chamber 5 is formed in a shape in which the entire upper surface is opened upward.

  In a position higher than the upstream opening edge of the nutrient solution storage chamber 5 (upper right side in FIG. 1), nutrient solution water W containing a component (organic fertilizer) necessary for the growth of the large piece A1 is stored. A nutrient solution tank 6 is disposed. Further, inside the nutrient solution tank 6 is stored a quantity of nutrient water W necessary for year-round cultivation of the sprout Aa of the large piece A1.

  The nutrient water W contains a lot of components (organic fertilizer) necessary for the growth of the large cocoon pieces A1, but it is a fermented bacterium that is a mixture of lactic acid bacteria Da, yeast Db, and natto Dc. D is an additive obtained by culturing D in a culture solution F containing, as a main component, brown sugar Ea extracted from organically grown agricultural products and / or stevia sweetener Eb extracted from stevia grass. May be added to the nutrient water W as appropriate.

In other words, if cultivating large persimmon A or large persimmon piece A1 with nutrient water W to which the additive is added, fermenting bacteria D consisting of lactic acid bacteria Da, yeast Db, natto Dc, brown sugar Ea and / or stevia sweetener The natural sweetener E of Eb will be contained in the sprout Aa.
For this reason, if the sprout Aa grown to the desired length is harvested and administered caliber, the fermenting fungus D consisting of lactic acid bacteria Da, yeast Db and natto Dc contained in the sprout Aa, brown sugar Ea and / or stevia sweetness Eb natural sweetener E can be taken together.

  Thereby, the effect by the several component contained in lactic acid bacteria Da, yeast Db, natto bacteria Dc which are fermenting bacteria D, brown sugar Ea which is natural sweetener E, and stevia sweetener Eb is synergistically obtained.

In addition, brown sugar Ea and stevia sweetener Eb are effective in increasing the absorption efficiency of vitamins and minerals, recovering fatigue, mental stability, and promoting blood circulation. Moreover, you may use the nourishing water W which has an additive as a main component for cultivation of Oiso A or Oiso piece A1.
On the outer wall of the bottom of the nutrient solution tank 6, the nutrient solution water W is supplied to the nutrient solution storage chamber 5 via a valve 7 for adjusting the outflow amount of the nutrient solution water W flowing out of the nutrient solution tank 6. One end of a nutrient solution supply path 8 for supply is connected. Further, the supply port 8 a formed at the other end of the nutrient solution supply path 8 is provided close to the bottom portion in the nutrient solution storage chamber 5.

The downstream side wall portion of the nutrient solution storage chamber 5 that separates the portion of the cultivation box 2 where the gravel layer S is spread and the portion of the nutrient solution storage chamber 5 where the nutrient solution water W is stored is located in the cultivation box 2. A supply port 5 a for supplying the nutrient solution water W released into the nutrient solution storage chamber 5 is opened between the heat insulating materials 2 laid on the left and right bottoms.
Further, one end of the nutrient solution supply path 4 is inserted into the supply port 5a of the nutrient solution storage chamber 5 from the downstream side, and is introduced into the nutrient solution storage chamber 5 from the supply port 5a.

  That is, since the nutrient solution tank 6 is disposed at a position higher than the cultivation box 2, when the valve 7 is opened, the nutrient solution water W stored in the nutrient solution tank 6 is fed to the nutrient solution supply path 8 by its own weight. Leaked. Further, when the valve 7 is closed, the outflow from the nutrient solution tank 6 to the nutrient solution supply path 8 is stopped.

  The nutrient solution water W discharged from the supply port 8a of the nutrient solution supply path 8 is temporarily stored in the nutrient solution storage chamber 5, but from the supply port 5a of the nutrient solution storage chamber 5 to the left and right bottoms in the cultivation box 2 It is supplied toward the space between the heat insulating materials 2 laid on the wall. Moreover, it is supplied on the waterproof sheet 12 laid in the lower part of the nutrient solution supply path 4 between the heat insulating materials 2.

  A discharge port 2 a for discharging the surplus nutrient solution water W flowing down to the downstream bottom portion in the cultivation box 2 to the outside is opened in the downstream bottom outer wall of the cultivation box 2. The other end of the nutrient solution supply path 4 is inserted from the upstream side into the discharge port 2a and protrudes outside the cultivation box 2 from the discharge port 2a. That is, the excess nutrient water W discharged from the discharge port 2a is discharged toward the inside of the liquid storage tank 10 to be described later.

  On the projecting side of the nutrient solution supply path 4, a valve 9 is provided for adjusting the amount of nutrient solution water W discharged from the discharge port 4 b formed at the other end of the nutrient solution supply path 4. ing. Moreover, the discharge port 4b of the nutrient solution supply path 4 is opened toward the inside of the liquid storage tank 10 to be described later.

  That is, when the valve 9 is opened, the nutrient solution water W discharged from the discharge port 4 b of the nutrient solution supply path 4 is supplied to the storage tank 10. Further, when the valve 9 is closed, the discharge port 4b of the nutrient solution supply path 4 is closed, and the release of the nutrient solution W is stopped.

  A storage tank 10 for storing the nutrient solution water W discharged from the discharge port 4b of the nutrient solution supply path 4 is disposed at a position lower than the bottom on the downstream side of the cultivation box 2 (lower left side in FIG. 1). ing. Further, the liquid storage tank 10 is formed in a shape in which the entire upper surface is opened upward.

  At the upstream end of the nutrient solution supply path 4 introduced into the nutrient solution storage chamber 5, the nutrient solution W stored in the reservoir 10 is supplied to the nutrient solution supply path 4. One end of the nutrient solution circulation path 11 for returning to the upstream side is connected. Further, a suction port 11 a formed at the other end of the nutrient solution circulation path 11 is provided in the nutrient solution water W stored in the reservoir tank 10.

The nutrient water W discharged from the outlet 4 b of the nutrient solution supply path 4 to the storage tank 10 is sucked up from the suction port 11 a of the nutrient solution circulation path 11 and returned to the upstream side of the nutrient solution supply path 4. Therefore, the nutrient solution water W can be circulated in one cultivation box 2.
In addition, since a liquid feeding device such as a pump is unnecessary, the configuration of the entire device can be simplified and the manufacturing cost can be reduced.

  Since the nutrient solution water W is circulated in one cultivation box 2, for example, the nutrient solution water W in the cultivation box 2 is contaminated with a substance that inhibits the growth of the large piece A1 or the large piece A1 grows. Even if infected with a disease that hinders the cultivation, the nutrient water W of the adjacent cultivation box 2 is not contaminated, and the large piece A1 is also prevented from being infected with a disease that hinders the growth. be able to.

  The illustrated embodiment is configured as described above, and hereinafter, a method for cultivating large potato pieces A1 taken out from the bulbous ridge A with the ridge cultivation apparatus 1 will be described.

  First, as shown in FIG. 1, the skin of a large ridge A having a bulbous shape is peeled, and a plurality of large ridge pieces A1 are taken out from one large ridge A. The taken out large cocoon pieces A1 are embedded one by one in the gravel layer S spread in the cultivation box 2, and aligned and arranged in two rows at equal intervals in the front-rear direction in parallel with the longitudinal direction of the cultivation box 2. (See a in FIG. 3).

Next, the nutrient water W supplied to the inside of the nutrient solution supply path 4 is fed from the hole 4a of the nutrient solution supply path 4 by the capillary phenomenon of the gravel layer S spread inside the cultivation box 2. Since the liquid water W is gradually sucked up, the internal pressure of the nutrient solution supply path 4 is lowered.
When the internal pressure of the nutrient solution supply path 4 decreases, the nutrient solution W stored in the reservoir tank 10 is drawn from the suction port 11a of the nutrient solution circulation path 11 and supplied to the inside of the nutrient solution supply path 4 Is done. Thereby, the nutrient water W is circulated and supplied.

  Further, if the inside diameter of the nutrient solution supply path 4 is made as small as the hair, or if the inside of the nutrient solution supply path 4 is filled with, for example, a fiber body or a sponge, the inside of the nutrient solution supply path 4 Due to the capillary action that occurs, the nutrient solution water W stored in the storage tank 10 can be circulated and supplied to the lower layer side of the gravel layer S spread within the cultivation box 2.

  The nutrient solution water W flowing out from the hole 4a of the nutrient solution supply path 4 is permeated into the nutrient solution diffusion sheet 13 laid between the nutrient solution supply path 4 and the gravel layer S and diffuses the nutrient solution. The sheet 13 is uniformly diffused.

  The nutrient solution water W that has penetrated into the nutrient solution diffusion sheet 13 is immersed in the gap between the gravel layers S due to the capillary phenomenon of the gravel layers S spread inside the cultivation box 2, and from the lower layer side of the gravel layers S to the upper layer Slowly sucked toward the side. Thereby, it supplies equally with respect to the large piece A1 embedded in the gravel layer S.

  The nutrient water W sucked up near the surface of the gravel layer S is transpired from the surface of the gravel layer S into the atmosphere, and also near the surface of the gravel layer S due to heat exchange that occurs when the nutrient water W evaporates. Is cooled or maintained at a temperature (for example, a low temperature included in the range of 4 ° C. to 9 ° C.) suitable for the growth of the large piece A1. As a result, the growth (rooting / germination) of the large cocoon piece A1 having psychrophilicity is promoted (see b in FIG. 3).

  The sprout Aa of the large piece A1 embedded in the gravel layer S grows to a length of, for example, about 20 cm to 25 cm in about two weeks, so the root part of the sprout Aa protruding above the surface of the gravel layer S is cut. If it cuts and cuts with a tool, the sprout Aa photosynthesis | combined with green can be harvested (refer c of FIG. 3).

  Even after the sprout Aa is cut off, new sprout Aa grows from the large piece A1 embedded in the gravel layer S. Thereby, the sprout Aa of the large piece A1 grown to the length can be harvested in about two weeks.

  In addition, when the vitality of the large piece A1 embedded in the gravel layer S is reduced or the nutrient is depleted and the harvest of the sprout Aa cannot be obtained, the large piece A1 for seed is taken out from the gravel layer S, and the large piece for new seed If the piece A1 is embedded in the gravel layer S again and cultivated, the sprout Aa of the large potato piece A1 grown to the length can be harvested in about two weeks. If this is repeated, the sprout Aa can be harvested any number of times.

  Compared with the gravel Sa used in the present invention, the general cultivated soil is softer, so that the roots of the large piece A1 tend to extend vertically and the number of roots is very small. Therefore, since the amount of the nutrient water W absorbed from the roots of the large piece A1 is small and it takes days to extend to the desired length, short-term harvesting cannot be expected.

Therefore, when cultivated using the gravel Sa according to the present invention, the roots of the large pods A1 are prevented from coming into contact with the gravel Sa and trying to extend vertically during the growth, but the roots of the large pods A1 are gravel. Since the gap of Sa is found and stretched, the growth of roots is trained and the number of roots increases.
For this reason, since the fertilizer contained in the nutrient solution water W is easy to be absorbed from the root of the large cocoon piece A1, and the growth of the large cocoon piece A1 is promoted, the number of days required for the sprout Aa of the large cocoon piece A1 to extend to the desired length. Becomes shorter.

  Moreover, the sprout Aa of the large chopped piece A1 to be harvested becomes dense, has a good aroma, and provides a mellow taste. Moreover, it is delicious and has high nutritional value. Furthermore, it is possible to harvest healthy sprout Aa that is less susceptible to diseases that hinder growth.

  In addition, if the sprout Aa grown to a length of about 20 cm to 25 cm is harvested, the odor peculiar to the potato is hardly released, so even those who dislike the odor specific to the potato can be eaten. It can be used for various purposes and purposes such as confectionery.

  In addition, the sprout Aa of the large slice A1 is rich in various components such as allicin, carotene, vitamins, minerals, etc., and has an antioxidant action to suppress active oxygen and a function to prevent illness by enhancing immunity. Is obtained.

As described above, since the environment in which the growth of the large cocoon piece A1 is promoted is maintained, the sprout Aa of the large cocoon piece A1 can be cultivated throughout the year, and the yield of the sprout Aa can be increased.
Note that the large piece A1 may be embedded in the number of columns such as one column, three columns, and four columns, for example, and is not limited to the number of columns in the embodiment.

  FIG. 5 is a longitudinal side view showing another method for cultivating potatoes by the cultivating apparatus 1, FIG. 6 is a central longitudinal end view showing the cultivating method for cultivating the cultivating apparatus 1 of FIG. 5, and FIG. It is explanatory drawing which shows a growth condition.

  In the large persimmon cultivation apparatus 1 of this example, the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  First, the skin of the large ridge A having a bulbous shape is not peeled off, and the large ridge A is held in a posture in which the root side faces downward, and is embedded in the gravel layer S spread in the cultivation box 2 (see d in FIG. 7). .

  Since it is cultivated in the same manner as in the above example, the growth (rooting / germination) of Otsuchi A having a chilling property is promoted (see e of FIG. 7), and has substantially the same operations and effects as in the above example. Can do. Further, since a plurality (5 to 6) or a plurality of sprout Aa grows upward from the bulbous large ridge A, the number of sprout Aa harvested from one large ridge A increases. (See f in FIG. 7).

  Only one or two sprout Aa grows from the large ridge piece A1, but a plurality or more than one sprout Aa grows from the bulbous ridge Aa. For this reason, if the root part of the sprout Aa projecting upward from the surface of the gravel layer S is cut and cut with a cutting tool, the number of sprout Aa of the large spider A that is harvested in one harvesting operation increases. The amount can be increased.

FIG. 8 is a central longitudinal end view of the present apparatus showing a method for cultivating a large vine that is covered with a sheet-like cover 14 having light shielding properties and cultivated.
When cultivating large potato pieces A1 with the cultivating apparatus 1 of this example, the entire upper surface of the cultivation box 2 is covered with a cover 14 having a light-shielding property, and is indicated by an arrow in the figure irradiated on the sprout Aa of the large potato pieces A1 The sunlight F is shielded. A ventilation passage 15 for ventilation is provided between the upper edge portions on both sides of the cultivation box 2 and the lower edge portions on both sides of the cover 14.

  That is, since the sunlight F irradiated to the sprout Aa of the large bowl A1 is shielded by the cover 14, photosynthesis of the sprout Aa is suppressed. For this reason, the sprout Aa does not change to green, and the yellowish white sprout Aa can be harvested.

  In addition, when eating the photo-synthesized green sprout Aa, it is necessary to heat and cook to a hardness that is easy to eat, but a large amount of components contained in the sprout Aa flows out during the cooking. However, the yellowish white sprout Aa is softer than the green sprout Aa and requires less time for cooking. Therefore, the amount of loss of components contained in the sprout Aa is small, and various kinds of sprout Aa are included. It is possible to ingest many ingredients.

  FIG. 9 is a central longitudinal sectional end view of the present apparatus showing a method for cultivating large pods housed in a container 16 having light shielding properties.

  When cultivating the large cocoon piece A1 by the large cocoon cultivation apparatus 1 of this example, the container 16 shields sunlight F indicated by an arrow in the figure irradiated on the sprout Aa of the large cocoon piece A1. An opening / closing door 17 for taking in and out the cultivation box 2 is attached to the front side wall portion of the container 16 so as to be freely opened and closed. A plurality of ventilation holes 18 are formed in the rear side wall of the container 16.

  That is, as in the previous embodiment, since the sunlight F irradiating the sprout Aa of the large piece A1 is shielded by the container 16, the yellow-white sprout Aa that has a soft texture and is rich in various components is harvested. can do.

  In place of the container 16, for example, it may be cultivated in a building such as a cultivation room or a cultivation facility.

FIG. 10 is an enlarged cross-sectional view showing a porous body G used in place of the gravel Sa.
The porous body G of this example is formed in a spherical or granular shape with a plastic having a diameter of about 2 mm to 10 mm, like the gravel Sa.

  On the outer peripheral surface of the porous body G, a hole Ga having a round cross section is formed in the radial direction from the center of the porous body G to the outer peripheral portion. In addition, a large number of pores Ga are formed radially around the center of the porous body G.

  When the porous body layer (not shown) made of the porous body G of this example is spread inside the cultivation box 2 and used in the cultivation method for cultivating the sprout Aa of the large ridge A or the large ridge piece A1, The nourishing water W supplied to the bottom of the cultivating box 2 easily penetrates into the gaps between the porous body layers made of the porous body G spread inside the cultivation box 2 and the pores Ga of the porous body G. It is possible to stably supply the nutrient water W in an amount necessary for the growth of the large piece A1.

In addition, the porous body G having a large number of pores Ga has a larger surface area than the gravel Sa and the efficiency of transpiration of the nutrient water W, so that the porous body G near the surface of the porous body layer in which the porous body G is spread. The air temperature can be maintained at a temperature suitable for the growth of the large ridge A or the large ridge piece A1.
As a result, the growth of the chilling large ridge A or large ridge piece A1 is promoted, and therefore, substantially the same operations and effects as the above-described embodiment can be achieved. Instead of the porous body G, natural porous stone such as pumice may be used.

In the correspondence between the configuration of the present invention and the embodiment,
The sand layer of the present invention corresponds to the gravel layer S composed of the gravel Sa of Examples and the porous layer composed of the porous body G,
Similarly,
The nutrient solution supply means corresponds to the nutrient solution supply path 4,
The nutrient solution diffusing means corresponds to the nutrient solution diffusion sheet 13,
The present invention is not limited to the configuration of the above-described embodiment, but can be applied based on the technical idea shown in the claims, and many embodiments can be obtained.

  When harvesting the sprout Aa, the sprout Aa may be harvested with the large spider A or the large spider A1 attached. Thereby, since the nutrient contained in the large ridge A and the large ridge piece A1 is replenished to the sprout Aa, the fresh state at the time of a harvest can be kept long.

Instead of the gravel Sa, natural porous stone such as washing sand, pebbles, or pumice may be used.
Further, the gravel layer S is laminated in order from the lower layer side, for example, a large sand layer made of gravel with a diameter of about 10 mm, a medium sand layer made of gravel with a diameter of about 6 mm, and a small sand layer made of gravel with a diameter of about 2 mm. It may be configured.
Furthermore, either a medium diameter sand layer or a small diameter sand layer may be laminated on the large diameter sand layer, or a small diameter sand layer may be laminated on the medium diameter sand layer. Or you may laminate | stack a medium diameter sand layer and a large diameter sand layer on a small diameter sand layer.

In addition, the additive added to the nutrient water W is optimally cultivating the fermentative bacteria D composed of lactic acid bacteria Da, yeast Db, and natto Dc in the culture solution F. A plurality of species may be changed to fermentative bacteria selected from other edible bacteria or the like, or all species of lactic acid bacteria, yeasts, and natto may be changed to bacteria other than the examples.
In addition, the culture solution F can be comprised by what melt | dissolved the natural sweetener with predetermined concentration with respect to water, such as natural water and distilled water, for example.

  The oak cultivation method and the oak cultivation apparatus 1 of the present invention can also be applied when cultivating agricultural products other than the oak A or the oak piece A1 of the examples.
