Referring to FIG. 1 , the apparatus for cultivating root plants according to the present embodiment may include a seedling cultivator 100 and a hydroponic cultivator 200 .

The seedling planter 100 is a device for growing seedlings (seedlings) of licorice (root plant) in culture soil, and the hydroponic planter 200 is the seedling planter 100 or other cultivation devices. It is a device for secondary growth of licorice above.

Here, although described later in detail, the seedling cultivation machine 100 has a structure suitable for growing the roots of licorice mainly in the longitudinal direction, and the hydroponic cultivation machine 200 has a structure suitable for growing the roots of licorice mainly in the diameter direction. Have. That is, the licorice cultivation apparatus according to the present invention includes two different cultivation machines 100 and 200, and by growing licorice in two stages of length growth and thickness growth, the commercial properties of licorice (root straightness and root thickness) ) and dramatically shorten the cultivation period.

However, the present invention is not necessarily limited to having to go through all two stages of length growth and thickness growth, including both the seedling cultivator 100 and the hydroponic cultivator 200 . That is, it may be carried out by selectively applying any one of the seedling cultivation machine 100 and the hydroponic cultivation machine 200 of the licorice cultivation apparatus according to the present embodiment.

Hereinafter, with reference to FIG. 2, which is an exploded perspective view of the seedling cultivation machine 100, and FIG. 3, which is a cross-sectional view showing a state of cultivating licorice using the seedling cultivation machine 100, the configuration of the seedling cultivation machine 100 and the seedling cultivation stage will be described in detail.

The seedling cultivation machine 100 is largely provided with seedling containers 110 and 120 and a water supply pipe 140 .

The seedling containers 110 and 120 are, as shown in FIGS. 2 and 3, licorice culture soil 30 is filled therein, and a bottomed tubular container with a drain hole 116 formed at the bottom. Specifically, the seedling containers 110 and 120 may include a lower container 110 and an upper container 120 that are a plurality of (two in this embodiment) sub-containers that can be stacked up and down. The upper container 120 has a cylindrical shape with open top and bottom, and the lower container 110 has a bottomed cylindrical shape with drain holes 116 and vent holes 118 formed at the bottom. The lower rim of the upper container 120 has an outer diameter slightly smaller than the outer diameter of the upper container 120 and a protrusion 121 protruding downward is formed, and the upper edge of the lower container 110 has a step 112 formed with a step. ) is formed, so that the protrusion 121 of the upper container 120 is seated on the step 112 of the lower container 110 , the lower container 110 and the upper container 120 can be combined.

In this way, by separating the seedling container into a plurality of sub-containers 110 and 120, the operation at the bottom of the seedling container, for example, before filling the seedling container with culture soil, the culture soil leaks into the drain hole 116 and the vent hole 118. It promotes work convenience when laying woven or non-woven fabrics (20, see Fig. 3) that prevent the coming out, or removing the culture soil after harvesting licorice, and The height can be adjusted appropriately.

On the other hand, the ribs 114 raised upwards are radially formed on the bottom of the lower container 110 to reinforce the rigidity of the bottom, so that the bottom is caused by the weight of the culture soil 30 filled in the seedling containers 110 and 120. Avoid sagging and sticking to the ground.

The water supply pipe 140 is a pipe with both upper and lower ends open, and the upper end is exposed above the culture soil 30 filled in the seedling containers 110 and 120, and the lower end is disposed to be embedded in the culture soil 30 to a predetermined depth (see FIG. 3). . The water supply pipe 140 is a member for directly supplying water or nutrient solution supplied through the water supply hose 145 (see FIG. 3 ) from the open upper end into the culture soil of the predetermined depth from the lower end. The function and effect of the water supply pipe 140 will be described later.

A plurality of water supply pipes 140 (five in this embodiment) may be provided in an appropriate number according to the capacity and size of the seedling grower 100. In this case, a constant interval between the water supply pipes 140 is maintained and water is supplied. A guide member 130 may be provided to guide an arrangement position of the pipe 140 .

As shown in FIG. 2 , the guide member 130 is on the upper end of the upper container 120 , similarly to the coupling method of the lower container 110 and the upper container 120 , the protrusion 131 of the guide member 130 . ) and the upper container 120 may be implemented in the form of a ring coupled by the step 122 .

A cantilever-shaped arm 132 protruding toward the center according to the number of water supply pipes 140 is provided on the inner circumferential surface of the ring-shaped guide member 130, and the arm 132 has elasticity at the tip of the water supply pipe 140. A finger 134 for gripping may be provided.

In addition, a hose hole 136 passing through the guide member 130 in a radial direction may be formed around the arm 132 of the guide member 130 . A water supply hose 145 for supplying water or a nutrient solution to the culture soil 30 may be inserted into the hose hole 136 .

By such a guide member 130 , the water supply pipe 140 may be detachably coupled to the seedling container 120 . Furthermore, the water supply pipe 140 may be coupled to a controllable depth of being embedded in the culture soil 30 in a state held by the fingers 134 . In addition, a scale 141 may be formed on the surface of the water supply pipe 140 so as to easily grasp the depth of being embedded in the culture soil 30 along the longitudinal direction thereof. On the other hand, the reason for controlling the depth of the water supply pipe embedded in the culture soil will be described later.

On the other hand, each member of the aforementioned seedling planter 100 may be made of metal such as plastic, fiber-reinforced plastic, or stainless steel, but the present invention is not limited by the material of these members.

In addition, the above-mentioned seedling cultivation machine 100 can be designed in various ways according to the size or number of plants to be grown, and also considering the efficiency and productivity of workers. As an example, in this embodiment, assuming that dozens of licorice seedlings are grown in one seedling cultivation machine 100, the total height of the seedling cultivation machine 100 is 50-100 cm, the horizontal length (diameter) is 50-100 cm, and watering The length of the pipe 140 may be 50 to 100 cm. However, the present invention is not limited by this size.

In addition, in the above description, the lower container 110, the upper container 120, and the guide member 130 were separately provided and described as configuring the seedling grower 110 in such a way that they are coupled to each other, but some or all of these members may be configured as a single unit.

Next, a process for cultivating licorice using the seedling cultivation machine 100 configured as described above will be described.

First, a woven or nonwoven fabric is laid on the bottom of the lower container 110 , or gravel is placed on the drain hole 116 and the vent hole 118 , and then the upper container 120 is coupled on the lower container 110 . Then, the licorice culture soil 30 is filled to an appropriate height in the seedling container formed by the combined upper container 120 and the lower container 110 .

Then, the licorice seedlings to be cultivated in the licorice culture soil 30 are planted at appropriate intervals. Here, licorice seedlings are produced by sowing licorice seeds.

Then, it enters the full-scale seedling cultivation stage, initially water or nutrient solution is supplied from the upper part of the culture soil 30 . Specifically, the tip of the water supply hose 145 inserted into the hose hole 136 formed in the guide member 130 is placed on the surface of the culture soil 30 , and a predetermined amount of water or nutrient solution is supplied.

Then, when the licorice root 10 grows to some extent, as shown in FIG. 3 , water or nutrient solution is supplied from the lower end of the water supply pipe 140 by supplying water or nutrient solution through the water supply pipe 140 .

Here, the depth at which the water supply pipe 140 is embedded in the culture soil 30 is deeper than the lower end of the root 10 of licorice. That is, the water supply pipe 140 functions to directly supply water or nutrient solution to a position deeper than the lower end of the root 10 of licorice.

At this time, the depth at which the water supply pipe 140 is embedded in the culture soil 30 is approximately 40 to 80 cm as shown in FIG. 3 from the beginning, so that the water or nutrient solution supplied through the water supply hose 145 and the water supply pipe 140 is Although it may always be supplied at a constant depth, it is preferable to drive the water supply pipe 140 deeper and deeper as the licorice root 10 grows so that water or nutrient solution is supplied from below the lower end of the licorice root 10 . Then, it is possible to properly promote the downward growth of the licorice root 10 and prevent laterally bending, thereby maximizing the length growth and straightness of the licorice root 10 .

On the other hand, in Patent Document 1, it is disclosed that licorice roots are cultivated using the property that licorice roots go down in search of moisture by supplying water by installing a hose having a number of holes at the bottom of a cultivation facility (container) filled with culture soil. have. However, in the cultivation facility of Patent Document 1, the installation depth of the water supply hose is fixed, so it is difficult to fully utilize the property of the licorice root to find moisture at the initial stage of licorice cultivation. There is a problem such as entering the hole formed in the hose and clogging the hole.

In contrast, the water supply pipe 140 of the present invention can control the depth of being embedded in the culture soil 30, without the same problem as in Patent Document 1, depending on the growth degree of the licorice root 10 from the beginning to the end of the seedling cultivation stage. Appropriately, length growth can be promoted.

In this way, when licorice is grown in length for about 9 months using the seedling cultivation machine 100, licorice root 10 having a length of about 40 to 80 cm and a thickness (diameter) of 0.5 to 1 cm, depending on the cultivation environment and irrigation cycle, etc. can be cultivated

It is preferable that the licorice grown in this way further go through the following hydroponic cultivation step of mainly growing in thickness rather than length in order to further increase marketability.

Hereinafter, with reference to FIG. 4, which is an exploded perspective view of the hydroponic cultivation machine 200, and FIG. 5, which is a partial cross-sectional view showing a state of cultivating licorice using the hydroponic cultivation machine 200, the configuration of the hydroponic cultivation machine 200 and the hydroponic cultivation steps will be described in detail.

The hydroponic grower 200 is a device for hydroponic cultivation by immersing the lower end with the growth point of the licorice root 10' in the nutrient solution, and as shown in FIGS. 4 and 5, the hydroponic container 220 and the support part 230. to provide

Hydroponic container 220 is made of a bottomed tubular shape into which the nutrient solution 40 can be filled. The hydroponic container 220 is connected to a nutrient solution supply system for supplying and draining the nutrient solution at a predetermined cycle through a flow path and a pump (not shown). Such a nutrient solution supply system may be configured as a circulation type in which the drained nutrient solution is filtered and the insufficient nutrients and water are added and supplied again.

The support 230 is disposed on the upper part of the hydroponic container 220, and supports the licorice root 10' by fixing the upper end of the licorice root 10' so that it hangs down. The support unit 230 may support and fix the plurality of licorice roots 10 ′ at the same time. That is, for example, as shown in FIG. 4, the support 230 may be formed in a plate shape, and a plurality of support holes 233 are formed in a lattice shape at a predetermined interval in the plate-shaped support 230, It can be supported by fixing the upper end of the licorice root 10', one for each support hole 233.

On the other hand, the support 230 may be configured so that the separation distance from the hydraulic container 220 is adjustable. This is, as will be described later, during hydroponic cultivation, the licorice root 10 ′ mainly grows in thickness rather than in length, but the depth at which the licorice root 10 ′, which slightly increases in length as the cultivation period elapses, is immersed in the nutrient solution is within a predetermined range. , for example, so that the lower end with a growth point is about 5 to 20 cm.

To this end, the hydroponic planter 200 may further include a frame 210 as shown in FIG. 4 . Frame 210 is made of a substantially rectangular parallelepiped, the frame 210, the inner bottom of the hydroponic container 220 may be disposed. In addition, since a plurality of jaws 212 are formed at a predetermined height on the vertical column of the frame 210, the spacing between the support unit 230 and the hydraulic container 220 by attaching the support unit 230 to the jaw 212 of an appropriate height. You can adjust the distance.

In addition, as shown in FIG. 4 , grooves 231 are formed near the front end at both sides of the support 230 . This is a configuration for easily adjusting the separation distance between the support 230 and the hydraulic container 220. That is, at the initial stage of cultivation, the support 230 is pushed from the front to the rear of the frame 210 in a drawer-type manner, and hydroponics is carried out in a state hung on the lower jaw 212, and the length of the licorice root 10 ' becomes longer and the support part When the 230 is moved to the upper jaw 212, the support 230 is slightly drawn out to the front of the frame 210 as much as the groove 231 and the jaw 212 coincide, and lifted up to the upper and lower jaws ( When the 212 passes through the groove 231 , and the support 230 is slightly pushed toward the rear of the frame 210 , the support 230 can be hung on the upper jaw 212 .

On the other hand, the hydroponic planter 200 according to the present embodiment, although not shown in the drawing, further includes a light-shielding film surrounding the four sides of the frame 210 . This light-shielding film prevents the licorice root 10' from being exposed to light such as sunlight, and maintains the humidity inside the hydroponic grower 200 so that the surface of the licorice root 10' does not dry. Although described later in detail, hydroponics cultivation of licorice using the present hydroponic grower 200 is to grow the licorice root 10 ′ in thickness rather than length, and when the surface of the licorice root 10 ′ is dry and hardened, the thickness grows. This may not be smooth.

In addition, the hydroponic planter 200 according to the present embodiment may further include a moisturizing pipe 250 . The moisturizing pipe 250 is a member that individually wraps the licorice root 10' to more reliably prevent drying of the licorice root 10' in addition to the light-shielding film. In this case, the upper end of the licorice root 10 ′ is fixedly supported by interposing a rubber or sponge 252 (see FIG. 5 ) at the upper end of the moisturizing pipe 250 . In addition, the moisturizing pipe 250 has a flange portion 251 extending in the radial direction at the upper end thereof, and when the moisturizing pipe 250 is inserted into the support hole 233 of the above-described support portion 230, the flange portion 251 is formed. The moisturizing pipe 250 can be easily fixed to the support part 230 by being caught in the support hole 233 .

Furthermore, the hydroponic planter 200 according to the present embodiment may further include a water supply unit 240 . The moisture supply 240 may be implemented in the form of a water supply pipe or hose in which a nozzle 241 is formed to correspond to each support hole 233 of the support part 230 . That is, by periodically or intermittently using the moisture supply 240, and supplying moisture into the moisture pipe 250 through the upper end of the moisture pipe 250 (see FIG. 5), the drying of the licorice root 10 ′ is prevented. more reliably preventable.

On the other hand, each member of the aforementioned hydroponic planter 200 may be made of metal such as plastic, fiber-reinforced plastic, or stainless steel, but the present invention is not limited by the material of these members.

In addition, the above-mentioned hydroponic cultivation machine 200 can be designed in various ways according to the size or number of plants to be grown, and also considering the efficiency and productivity of workers. As an example, this embodiment assumes that several dozen licorice roots 10' are grown in one hydroponic planter 200, and the total height of the hydroponic planter 200 is 60-120cm, and the horizontal and vertical length is 50- 100 cm can be done. In addition, the moisturizing pipe 250 may have an inner diameter of 5 to 10 cm and a length of 50 to 80 cm. However, the present invention is not limited by this size.

On the other hand, in the above-described hydroponic grower 200, the height of the support 230 by holding the support 230 on the plurality of jaws 212 formed at different heights, that is, the separation distance between the support 230 and the hydroponic container 220. control, but the present invention is not limited to this structure.

For example, as shown in FIG. 6 , teeth 214 are formed on the inner surface of the vertical column of the frame 210 ′ opposite to the support 230 , and both sides of the support 230 have teeth 214 on both sides. By providing the stopper 235 to be hung, it is possible to implement the function of adjusting the height of the support 230 . In this case, the stopper 235 is rotatably coupled to the hinge shaft 236 and is elastically biased in a direction protruding from both sides of the support part 230, so that the support part 230 can be moved in only one direction, that is, upward. has a structure with

In addition, without providing the jaws 212 or the teeth 214 on the frames 210 and 210', an upper frame (not shown) is provided on the upper portion of the hydraulic container 220, and the support portion 230 on the upper frame. The structure may be fixed by hanging with a wire (not shown). In this case, the height adjustment function of the support part 230 may be implemented by adjusting the length of the wire on which the support part 230 is suspended.

Furthermore, the aforementioned hydroponic grower 200 is configured to maintain the depth at which the licorice root 10 ' is immersed in the nutrient solution within a predetermined range by adjusting the separation distance between the support part 230 and the hydroponic container 220, but the support part ( By adjusting the separation distance between the 230) and the hydroponic container 220, it is not necessary to maintain the depth at which the licorice root 10' is submerged in the nutrient solution within a predetermined range. That is, by adjusting the water level of the nutrient solution 40 filled in the hydroponic container 220 to match the length of the licorice root 10 ′, the depth at which the licorice root 10 ′ is submerged in the nutrient solution may be maintained within a predetermined range. In this case, the configuration of the hydroponic cultivation machine 200 can be simplified.

On the other hand, although the hydroponic container 220 is filled with the nutrient solution in the hydroponic cultivation machine 200 described above, the culture soil may be further filled in addition to the nutrient solution. That is, as shown in FIG. 5 , the culture soil 30 is below the hydroponic container 220 , and the nutrient solution 40 is filled above the culture soil. In this case, the licorice root 10 ′ is initially immersed in the nutrient solution 30 and then digs into the culture soil 30 when the length is further increased downward. Then, the licorice root 10' is supported more stably and a more reliable moisturizing effect can be obtained.

Next, a hydroponic cultivation step of cultivating licorice using the hydroponic cultivation machine 200 configured as described above will be described.

First, the hydraulic container 220 is placed on the inner bottom of the frame 210 , and the support 230 is hung on the lower jaw 230 of the frame 210 .

Next, the upper end of the licorice root to be grown hydroponically is fixed to each support hole 233 of the support 230 . On the other hand, when using the moisturizing pipe 250, the upper end of the licorice root is fixed to the upper end of the moisturizing pipe 250, and the moisturizing pipe 250 is fixed by inserting it into each support hole 233 of the support unit 230. . At this time, it is preferable that about 5 to 20 cm of the lower end of the licorice root 10 ′ fixed to the support 230 is immersed in the nutrient solution 40 . Licorice, which is the subject of hydroponic cultivation in this embodiment, is preferably licorice grown to a length of 40 to 80 cm and a thickness (diameter) of several mm to 2 cm by the seedling cultivation machine 100 described above, but the present invention is not limited thereto.

Then, the side of the frame 210 is wrapped with a light-shielding film to block the licorice root 10' from light.

On the other hand, when using the moisturizing pipe 250 and the moisture supply 240, each nozzle 241 of the moisture supply 240 is inserted into the upper end of each moisture supply pipe (250).

Then, the nutrient solution 40 is supplied to the hydroponic container 220 and hydroponic cultivation is performed in earnest. At this time, when using the moisturizing pipe 250 and the moisture supply 240, periodically or intermittently through the moisture supply 240, the moisture is supplied into the moisture pipe 250 through the upper end of the moisture supply pipe 250. .

Then, since the lower end of the licorice root 10 ′ with the growth point is already immersed in the nutrient solution 40 , the licorice root 10 ′ seeks moisture and grows downward with nutrients supplied by the nutrient solution 40 , rather than Thickness, i.e. volumetric growth, prevails. However, there may be some length growth even if the thickness growth of the licorice root 10' is dominant by the hydroponic cultivation step. In this case, by slightly increasing the separation distance between the support 230 and the hydroponic container 220 by the above-described means, or by slightly lowering the water level of the nutrient solution 40 in the hydroponic container 220, licorice root 10 ') It is enough to submerge the lower part of the nutrient solution 40 by about 5 to 20 cm.

At this time, if the process of periodically or non-periodically emptying and filling the nutrient solution in the hydroponic container 220 is repeated, the thickness of the licorice root 10 ′ grows than when the hydroponic container 220 is constantly filled with the nutrient solution 40 . can be promoted more effectively. This is because, when the nutrient solution is supplied intermittently, licorice tends to absorb the nutrient solution intensively while the nutrient solution is supplied, rather than when the nutrient solution is supplied regularly. As a result, when the nutrient solution is supplied intermittently, the amount of nutrient absorption increases and intensive growth in thickness can be achieved compared to the case where the nutrient solution is supplied regularly.

Meanwhile, as described above, the hydroponic container 220 may be further filled with culture soil in addition to the nutrient solution 40 . That is, as shown in FIG. 5 , the culture soil 30 is below the hydroponic container 220 , and the nutrient solution 40 is filled above the culture soil. In this case, the licorice root 10 ′ is initially immersed in the nutrient solution 40 and then digs into the culture soil 30 when the length is further increased downward. Then, the licorice root 10' is supported more stably and a more reliable moisturizing effect can be obtained.

In this way, when licorice is grown thickly for about 4 months to 1 year using the hydroponic cultivation machine 200, licorice root 10' having a length of about 50 to 100 cm and a thickness (diameter) of 3 to 6 cm can be obtained. .

As described above, if the length is mainly grown through the seedling cultivation step according to the present invention and then mainly grown in thickness through the hydroponic cultivation step, the length of about 50 to 100 cm and 3 to 6 cm in a short period of one to one and a half years. Licorice can be harvested with excellent marketability (root straightness and thickness) of the thickness (diameter) of On the other hand, in the case of conventional open-field cultivation, licorice with excellent marketability could not be harvested even after a normal cultivation period (2 and a half to 3 years).

Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto and will be described below with the technical idea of the present invention by those of ordinary skill in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims.
