Definition of Terms

As used herein, the term 'micro bubble' (hereinafter also referred to as 'MN bubble') means that the diameter of the bubble falls within a range of 1 nanometer to 999 micrometers.

As used herein, the term "seedling plant" means "a young plant having roots used for cultivating crops or propagating trees", for example, rice (nursery), babe leaf (sprouts) Medicinal plants and the like.

FIG. 1 is a view for explaining a plant growth control control system (hereinafter referred to as 'the present planting system') using microbubbles according to an embodiment of the present invention.

The culture unit 10 is a structure for cultivating a seedling plant, for example, a port where seedling plants are placed, or a structure composed of a plurality of trays.

Nursery plants can be placed and cultured on each of these plurality of trays. On the other hand, each of the trays has a structure in which the space is limited. When the nursery plants are cultivated in the culture unit 10 having such a limited space, roots are caused according to the prior art, but roots can be prevented according to the present invention.

The pump 21 pumps the microbubble content water produced by the microbubble generator 80 and supplies it to the culture unit 10. [

The water flowing out from the culture unit 10 is supplied to the microbubble generator 80. A person skilled in the art can provide the water supply source separately provided to the micro-bubble generator instead of the culture unit 10 as necessary.

On the other hand, a person skilled in the art can, if necessary, provide a pump between the culture unit 10 and the micro-bubble generator 80 to supply water present in the culture unit 10 to the micro-bubble generator . For example, when a vortex nozzle as described later in FIGS. 10 to 13 is to be used in a plant growth controlling seedlings control apparatus using microbubbles, in order to improve the rotational force of water flowing into the nozzle, 10) and the micro-bubble generator.

The minute bubble generator 80 generates minute bubble containing water (meaning water (water) including at least a part of minute bubbles) containing minute bubbles. Here, the micro-bubble generating device includes a compressor 23, an MNB nozzle 25, a dissolution tank 33 for storing dissolved water-water dissolved therein, and a micro-bubble-containing water reservoir 27 A pump 35 for pumping the stored water and providing it to the dissolution tank 33, and a controller 60. 1, the minute bubble generator 80 is represented by a dotted line except for the MNB nozzle 25, but this is for convenience of illustration, and the MNB nozzle 25 is also a micro bubble generator, It should be understood by those skilled in the art that it is a component of < / RTI >

The compressor 23 compresses the air and injects the water into the path through which the water is moved to the dissolving tank 33 by the pump 35. For this purpose, an injector (not shown) may be located on the path of the water movement between the pump 35 and the dissolving tank 33, and the compressor 23 may inject air through the injector.

The cooler 30 allows the temperature of the water containing microbubbles to maintain a reference range (a value predetermined according to the type of nursery plant).

The temperature of the minute bubble-containing water is higher than that of the general water not containing minute bubbles (hereinafter referred to as 'general water'). To solve this problem, the cooler 30 is used.

The atomizing nozzle 40 receives the microbubble-containing water and is sprayed on the upper part of the seedlings plant cultivated in the culture unit 10.

The compressor 23 supplies air to the MNB nozzle 25.

The valve 50 may be disposed between the compressor 23 and the MNB nozzle 25 and the valve 50 may be controlled to be off when the operation of the compressor 23 is stopped.

The MNB nozzle 25 can generate minute bubbles and can generate fine bubbles by receiving the dissolved water in which the air is dissolved. This will be described later with reference to other drawings.

The controller 60 is for controlling the amount of minute bubbles included in the minute bubble containing water and can adjust the amount of air flowing into the MNB nozzle 25 by controlling the operation of the compressor 23, for example . This makes it possible to control the texture of nursery plants.

For example, the controller 60 can periodically turn the compressor 23 on or off, and in this case, the valve 50 can also be turned on or off in synchronization with the compressor 23.

The controller 60 may have information on whether microbubbles are always generated, periodically generated or periodically generated depending on the type of seedlings to be cultivated.

For example, the controller 60 may be configured to detect a mode (first operation mode) for always generating minute bubbles, an operation mode (second operation mode) for periodically generating minute bubbles, a PH of the culture unit 10, And an operation mode (third operation mode) for automatically generating or stopping minute bubbles based on the result.

In the first mode of operation, the controller 60 controls the associated components so that the microbubble content is generated.

In a second mode of operation, the controller 60 controls the associated components so that the microbubble content number is periodically generated. For example, one hour produces microbubble-containing water, the next one hour produces normal water, the next one hour microbubble-containing water, ... in this way, . For this purpose, the controller 60 can, for example, stop the operation of the compressor 23 periodically.

The seedling growing system may additionally include a sensing unit capable of sensing the pH of the culture unit 10 in real time.

In the third operation mode, the controller 60 can control the operation of the minute bubble containing water generating unit (the operation of generating minute bubbles) by referring to the sensing result of the sensing unit.

Components not illustrated in the components of FIG. 4 behave in the same manner as components in FIG. 1 that are designated by the same reference numerals.

FIG. 5 is a view for explaining a method for controlling plant growth control using microbubbles according to another embodiment of the present invention.

5, the seedling growing method includes the steps of generating microbubble-containing water (S201), supplying the produced microbubble-containing water to the cultivation unit 10 where the seedlings are planted (S203) (S205) of measuring the pH and the like of the seedlings planted in the step (10), and controlling the amount of microbubbles contained in the microbubble-containing water (S207).

Step S207 may be performed by adjusting the amount of air flowing into the microbubble generator that generates microbubble-containing water in order to control the texture of the seedlings planted in the culture unit 10.

The planting method may further include the step of maintaining the temperature of the microbubble-containing water at the reference temperature range.

In this method, steps S205 and S207 are optional, and the practitioner of the present invention can use it as needed.

In this method, the culture section is composed of a plurality of trays, the plurality of trays have a limited space, and the seedlings plant is cultured in this limited space. According to this method, roots are prevented even when seedlings are cultivated in a limited space.

Referring to FIG. 6, there is shown a photograph of a seedling plant (bean sprouts) cultivated according to the seedling growing system according to an embodiment of the present invention, which is represented by M / N, and T / W is a seedlings It is a plant (bean sprout).

As can be seen from FIG. 6, the comparison between the seedling plants (bean sprouts) cultivated according to the seedling growing system or the seedling growing method according to the embodiment of the present invention and the seedling plants (bean sprouts) cultivated using the common water, It can be seen that the seedling plants (bean sprouts) cultivated according to the seedling growing system according to the embodiment have relatively few roots and long roots. In this way, fewer long roots and less roots can prevent root rotations that may occur in cultivated areas such as trays.

FIG. 7 is a photograph for explaining another effect of a seedling plant cultivated by a seedling growing system or a seedling growing method according to an embodiment of the present invention.

Referring to FIG. 7, data indicated as bubble number soybean sprouts are data on seedlings planted in accordance with the seedling growing system according to an embodiment of the present invention, and data indicated as general water bean sprouts do not use microbubble- will be.

As can be seen from the data in FIG. 7, the crude protein content of the bean sprout was higher than that of the normal bean sprouts (ca. 34.38%). In addition, Ca, Fe, Mg, Zn, K, vitamin C, The content of functional components such as fibers is also higher. On the other hand, it can be seen that Na is higher in general water bean sprouts.

As described above, the seedling plants cultivated according to the seedling growing system according to the embodiment of the present invention and the seedling plants cultivated by the common water differ in the content of the functional ingredient.

By using this point, in the present invention, it becomes possible to control the content of the functional component. 1, the controller 60 can control the operation of the compressors 23 and 23 to control the amount of the minute bubbles contained in the water containing the minute bubbles. Therefore, the content of the functional components The texture can be controlled.

FIGS. 8 and 9 are views for explaining the role of microbubbles in the seedling growing system or the seedling growing method according to an embodiment of the present invention.

Referring to FIG. 8, the principle of acid growth theory is explained in the absence of micro-bubbles. First, oxine softens the cell walls and regulates acidic substances that act to change. The auxin increases the activity of the ATP synthase, which is distributed in the cell membrane, and transports the hydrogen ion to the cell wall, thereby lowering the pH to acidify it. In this case, the hydrogen ion weakens the hydrogen bond of the cell wall constituent, and the cell wall is loosened and the plasticity is increased. In other words, when the pH of the cell wall decreases, the cell wall weakens by the acid, and then water is absorbed into the cell, and when the pressure increases, the cell wall grows and the cell grows. Thus, the kidneys of the cells occur mostly at night, where absorption of water is great.

Referring to FIG. 9, in the case of normal water, hydrogen ions released from the cell wall side lower the pH around the cell wall to acidify. Eventually, the cell wall is weakened by the acid, so that the water is absorbed smoothly, so that the pressure inside the cell (pressure) increases the cell wall, which leads to the cell growth.

However, in the case of microbubbles containing water, the hydrogen ions are transported to the cell wall, but the OH radicals generated in the microbubbles are relatively larger than the hydrogen ions released from the cell walls, so that the pH of the attention is increased and the water is less absorbed into the cells Therefore, as shown in Fig. 7, the nursery plants cultivated using the actual microbubbles have a higher crude protein content than the nursery plants cultivated in the general water, resulting in good texture.

Therefore, according to the present invention, it is possible to control the growth by regulating the pressure of OH radicals, thereby increasing the content of the functional substance by the growth stress and controlling the texture.

Thus, according to the present invention, it is possible to control the growth of the roots of seedlings and / or crops, and the roots of nursery plants can be eliminated.

Furthermore, the functional material can be increased or decreased by artificially imparting stress to seedling plants and / or crops. For example, the content of functional ingredients such as vitamins and minerals can be increased or decreased.

These components may be integrally formed as shown, or at least some of them may be separately manufactured and assembled.

The wired part 111 is located at the center of the base part 119 and an air movement path 113 is formed in the wired part 111 to provide a path through which air can flow. In this embodiment, the air movement path 113 is formed in a straight line, but it may be formed in a spiral shape in order to cause air swirling.

An air movement path 115 for providing a path through which air can flow is also formed inside the base portion 119, and air is introduced from the outside through the air movement path 115.

The air movement path 113 formed in the wired portion 111 and the air movement path 115 formed in the base portion 119 are in communication with each other so that the air introduced into the air movement path 115 flows through the air movement path 113).

The diameter of the air movement path 115 formed in the base portion 119 is formed larger than the diameter of the air movement path 113 formed in the wired portion 111 in this embodiment. As a result, when the air flowing in the air movement path 115 moves to the air movement path 115, the pressure is increased to increase the flow velocity, and consequently contribute to the swirling of the air.
