Technical Field [0001] The present invention relates to a ginseng cultivation system for ginseng cultivation including a cooling water tank for indirect rhizospheric temperature control and a fresh water cultivation vessel diluted with a nutrient solution, wherein the ginseng cultivation system comprises hydroponic sprout fresh expression systems, }

The present invention relates to a fresh water type hydroponic cultivation system, and more particularly, to a system for improving the water quality and the quality of the ginseng industry by indirectly controlling the root zone temperature, which is the root portion of ginseng, The present invention relates to a fresh water-based hydroponic cultivation system for cultivating ginseng, including a cooling water tank for indirect temperature control and an aqueous solution-diluting fresh water container,

Generally, hydroponic cultivation refers to a method of cultivating a plant by using a culture medium made of water and a water-soluble nutrient by using an artificial pond or a container capable of supporting the plant without using soil, soilless culture, water culture.

The advantage of hydroponics is the ability to directly observe the condition and growth of roots, produce uncontaminated clean vegetables and plants continuously, and mass-produce commercially.

Multipurpose indoor hydroponic cultivation equipment can be cultivated easily by anyone in the house, and it also plays a role of cultivating emotions and utilizing it as a living gardening.

Plants that can be hydroponically cultivated include hydroponics such as cucumber, tomato, pepper, paprika and strawberry, lettuce, lettuce, lettuce, kale, parsley It is possible to cultivate hydroponics such as leafy vegetables, chrysanthemums, roses, gerberas, lilies, begonia, anthurium, etc., flowers, ginsengs and some medicinal plants.

On the other hand, ginseng is cultivated in the traditional way such as the cultivation of the land mainly, and the cultivation of the soil is required to be cultivated over 4-6 years, so that the cultivation period is too long and the cost is excessive. Therefore, price competitiveness is very weak.

In addition, the ginseng has many difficulties in recovering the hardwoods because it is difficult to produce in a single place due to its characteristic characteristics (due to root rot disease), and if it is produced in one place, it causes a great loss due to a drop in yield and a drop in quality.

Therefore, it is necessary to spray a large amount of soil fungicide, which causes many problems such as adverse effects and increased cost burden of farmers.

Therefore, efforts have been made to improve the quality of ginseng by shortening the cultivation period by hydroponics.

However, although the control of root zone temperature is very important in ginseng hydroponics, there are many failures due to the lack of proper control system. That is, in spite of hydroponic cultivation, the growth of ginseng is uneven and the yield is lowered and the quality is lowered.

Also, ginseng roots are very sensitive and weak in bacteria. In the normal hydroponic culture structure, when any one of the ginseng roots becomes diseased, the ginseng is infected with the whole ginseng, so that it has a limitation that the ginseng farming is ruined.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, the most important characteristic of the present invention is that the fresh water type hydroponic cultivation system for ginseng cultivation has the concept of controlling the root zone temperature.

In other words, ginseng may grow stem or not come up depending on roots environment. In other words, the damage of the root part affects the entire ginseng, so controlling the environment around the root should be the most important point when cultivating ginseng in hydroponics.

In particular, ginseng roots respond very sensitively to temperature changes. When temperature changes are large, they are not only unable to grow due to severe stress, but also die and die when they are severe, which is an important part of the farmer's income. .

For this reason, the system according to the present invention employs a fresh water type hydroponic cultivation method to easily detect and control a difference from the atmospheric temperature, and also adopts an indirect type temperature control method, which is one of the main features can see.

To this end, the water-based hydroponic cultivation system for ginseng cultivation according to the present invention includes a cooling water tank 100.

The cooling water tank 100 contains fresh water, and the fresh water is circulated and the water temperature is regulated.

In order to circulate the fresh water, a supply pipe 110 is provided on one side of the cooling water tank 100, and a drain pipe 120 is provided on the other side.

A supply solenoid valve 112 is installed in the supply pipe 110 and a drain solenoid valve 122 is installed in the drain pipe 120.

The supply solenoid valve 112 and the drain solenoid valve 122 are connected to the control panel 500 to control opening and closing.

The supply pipe 110 and the drain pipe 120 are connected to one side and the other side of the fresh water tank 200 and the fresh water stored in the fresh water tank 200 is supplied to the upper side of the fresh water tank 200 at a predetermined temperature And a cooler 210 for cooling the cooler 210. Since the cooler 210 is generally regarded as a well-known air conditioning system, a detailed description thereof will be omitted.

In addition, a supply pump 220 is installed on the pipe of the supply pipe 110 to supply fresh water, more precisely, cooled fresh water (cooling water) stored in the fresh water tank 200 to the cooling water tank 100 .

The water level sensor 130 is installed in the cooling water tank 100 and the level sensor 130 is connected to the control panel 500 to transmit and receive a detection signal. (220).

Of course, when fresh water, that is, cooling water is supplied, the drain solenoid valve 122 should be kept closed, and the supply solenoid valve 112 should be opened.

A number of cultivation tanks 300 are floated in the cooling water tank 100 and a certain number of ginsengs G are allowed to grow on the ginseng culture medium 140 in the cultivation water tank 300, G) are kept exposed to the both liquids filled in the cultivation water tank 300 through the ginseng culture medium 140.

Here, the reason why the cultivation water tank 300 is separated from the ginseng (G) only by containing a certain number of ginseng (G) is because the ginseng (G) root is composed of a polysaccharide different from other plants, When it is worn or damaged, ginseng roots contained in the same nutrient solution will become the same year, causing growth failure or destruction. If a large common tank is used, all of the ginseng roots must be discarded and the damage may become very large.

In addition, the ginseng culture medium 140 is made of a buoyant material such as a sponge made of a PE material having no problem of environmental hormones, and includes a plurality of fixing holes 141 for inserting ginseng one by one and maximizing the contact area between the nutrient solution and the air A plurality of air contact holes 142 are formed.

As shown in the enlarged view of FIG. 5, the fixing hole 141 has a propeller shape with three wings. When the ginseng having a large diameter is inserted, the fixing hole 141 is inserted into the middle portion 141a. In case of inserting, the ginseng is inserted into the edge portion 141b to stably fix the ginseng and prevent the growth of ginseng.

However, in the case of the present invention, only the cultivation water tank 300 suffering from the disease is taken out and replaced with a new one, so that the damage range can be minimized.

In particular, since the cultivation water tank 300 is floated on the cooling water tank 100, the nutrient solution is indirectly cooled by the cooling water contained in the cooling water tank 100, that is, The temperature change is not gentle but gentle.

Therefore, the root of ginseng (G) is less stressed, so it grows fast, and it has a strong and vigorous growth effect.

The temperature sensing sensor 150 is connected to the control panel 500 and provides temperature information sensed by the temperature sensing sensor 150 to the control panel 500 so that the control panel 500 can be cultivated The temperature change of the nutrient solution affecting the roots of the ginseng in the water tank 300 is checked in real time so that the temperature does not change greatly and the nutrient solution temperature is kept constantly within the range of 16 ° C to 20 ° C.

Herein, the above description has been mainly described in terms of cooling, which corresponds to the case of the summer season. In winter, it is necessary to switch to the concept of warming, and the coolant circulation direction is switched so that the cooler can naturally be heated. So that the temperature of the fresh water tank 200 is raised.

For this purpose, it is also important to control the temperature of the fresh water tank 200. The fresh water tank 200 is further provided with a fresh water temperature sensor (not shown) for checking the temperature and maintaining the temperature at a predetermined temperature, It is preferable to form a connection.

As described above, when the temperature control affecting the roots of ginseng (G) is indirectly performed using the cooling water tank 100, the ambient temperature close to 30-40 ° C in the summer (conversely, 13 ° C in winter Temperature of the ginseng roots, the temperature of the ginseng roots does not directly affect the roots of the ginseng since the atmospheric temperature change does not directly affect the ginseng roots by taking the dual indirect heat transfer structure such as the fresh water temperature slowly heated and relatively cooled, By minimizing stress, growth and growth can be improved.

That is, the present invention focuses on the effect of the temperature change on the root of ginseng rather than the concept of the nutrients contained in the nutrient solution. For example, the ginseng root receives severe stress even if the temperature change occurs at only 1 ° C Therefore, it is a very important concept to make the temperature change of indirect cooling and warming warm water gently based on a large number of temperature detection information, so that the temperature change of the nutrient solution is kept almost constant.

In addition, since the ginseng G is required to absorb light, that is, a light amount for growth, the supporting frame 400 having a size substantially such that the cooling water tank 100 can be completely contained therein is formed. Respectively.

Blowers 162 and 164 are installed on both sides of the support frame 400 to face each other so as to circulate air through the cultivation space. Respectively.

In this case, a cover (not shown) is placed on the outside of the support frame 400 to allow the ginseng G to grow in a certain space. Generally, hydroponic cultivation is performed in a room such as a glasshouse or a vinyl house In the case of such an indoor structure, the blowers 162 and 164 should be installed at appropriate positions of a glasshouse or a plastic house, not the supporting frame 400, so that they can be ventilated. If it is required to keep the room temperature constant A temperature sensor is further installed and controlled by the control panel, so that the room temperature can be kept constant by controlling the air flow rate and speed of the blower.

Further, it is most preferable that the control panel 500 is fixed on the support frame 400.

In the present invention, as shown in FIG. 2, the illumination unit 160 is preferably a bar-type LED lamp, and is arranged to emit light downward.

The reason why the light amount is irradiated using the illumination means 160 is to smooth the growth of ginseng G by photosynthesis.

In other words, 'photosynthesis' means 'synthesis using light', meaning that photosynthetic organisms use light as energy when synthesizing organic materials.

In other words, photosynthesis refers to the synthesis of glucose with carbon dioxide and water using light energy. The photosynthesis is classified into two types of photosynthesis: light reaction (photo-oxidation) and dark reaction, By converting light energy into ATP and NADPH ₂ , it supplies energy, inorganic phosphoric acid, reducing power and hydrogen to the dark circulation circuit, and the dark reaction synthesizes glucose by using ATP and NADPH ₂ in the chloroplast stroma, .

In addition, plant cells produce a large amount of ATP, which is chemical energy, by decomposing glucose through cytoplasm and mitochondria through a corresponding process, TCA circuit, and chemical osmotic phosphorylation. The free energy of ATP is 7.3 kcal / mole, The energy required for growth can be efficiently obtained.

Among these photosynthetic processes, length of day and photosynthetic photon flux density (PPFD) are the most influential factors for nutritional growth and reproductive growth of plants. Growth is different.

In addition, the plants are photosynthetic in the 380 ~ 760nm region including the visible light region, and the radiation energy in the wavelength range where photosynthesis occurs is called photosynthetically active radion (PAR) And the photosynthetic effective photon quantities are different.

Therefore, since greenhouses and plant factories often do not utilize sunlight directly, it is very important to secure the light necessary for crop growth, and artificial lighting is utilized in this case.

The present invention is characterized in that illumination means 160 which is an artificial illumination is provided so as to provide PPFD required for growth of ginseng G. The illumination means 160 controls the amount of light in accordance with the growth rate of ginseng G Thereby maintaining the optimum growth rate and achieving high quality.

The PPFD value required for the growth of ginseng is 60 ㏖ moles at the beginning of growth, 100 ㏖ mol at the middle stage of growth, and 120 ㏖ mol at the end. On the other hand, the lighting time required for growth is much needed at the beginning of growth and gradually decreases at the end of growth.

A light emitting unit PH1 and a light receiving unit PH2 are provided on opposite inner sides of the cooling water tank 100. The light emitting unit PH1 and the light receiving unit PH2 are mounted on a plate A plurality of photosensors may be installed, and the plate may have various shapes such as a small width or a large width. The design may be different according to the size of the cultivation bath 300, 300 should be formed transparently.

The light emitting unit PH1 and the light receiving unit PH2 are arranged in a direction perpendicular to the direction in which the light emitting unit PH1 and the light receiving unit PH2 are opposed to each other in the width direction that does not interfere with the cultivation water tank 300 A pair of guide bars GB are installed vertically and an illuminance sensor S is installed on the guide bar GB so that the illuminance sensor S can be moved up and down by a combination of a motor and a ball screw Respectively.

In addition, the control panel 500 includes a memory and is connected to the light emitting unit PH1 and the light receiving unit PH2 as well as the light intensity sensor S, Voltage or current to change the amount of light.

At this time, the PPFD value according to the development state of the ginseng (G) is stored as a table value in the memory, and the control panel 500 displays the height value (G) detected by the light emitting unit PH1 and the light receiving unit PH2 And whether the light amount is irradiated with the PPFD value corresponding to the height (the height of the ginseng) can be confirmed and controlled by the feedback of the light intensity sensor S.

That is, the key height information of the ginseng G is compared with the PPFD detected through the illumination sensor S and compared with the PPFD table value (stored in the memory as the reference value) corresponding to the crop growth, and if the PPFD is small Control the voltage or current to increase the amount of light or to increase the light irradiation time, and if necessary, control to decrease the amount of light.

In other words, it can be adjusted until it coincides with the reference value.

Thus, it is possible to receive the PPFD in an optimal state for growing ginseng (G), and to grow the high quality ginseng (G) in the shortest time.

Here, it is preferable to detect the PPFD by matching the illuminance sensor S to the uppermost one of the tallest ginsengs, because if the light amount is more than necessary, the light sensor will die, At least the smaller ginseng (G) do not die even if the amount of light is insufficient.

As another example, as in FIG. 3, the illumination means 160 itself may be modified to raise and lower for PPFD adjustment.

To this end, the lighting means 160 is constrained to the horizontal fixing table HF, and the horizontal fixing table HF is configured to be raised or lowered by a vertical guide VG fixed to the inner surface of the cooling water tank 100 At this time, various means such as a motor-gear-LM guide or a motor-pulley-belt or a motor-ball screw type may be applied.

On the other hand, the system according to the present invention can be modified into the form as shown in FIG. 4, thereby enabling more stable and efficient ginseng (G) hydroponics.

Referring to FIG. 4, a buffer tank 600 is further provided between the cooling water tank 100 and the cultivation water tank 300.

The reason why the buffer tank 600 is further provided is that the cultivation tank 300 near the point where the supply pipe 110 of the cooling water tank 100 is connected is more affected by temperature change than the cultivation tank 300 on the opposite side The phosphoric acid (G) roots on the cultivation water tank 300 near the supply pipe 110 may be subjected to a greater stress. This is to solve such a problem as well.

For example, when the cooling water is supplied in the summer season, the cultivation water tank near the discharge port of the supply pipe 110 from which the cooling water is sprayed is brought into contact with the cooling water having a relatively low temperature, and the cooling water is heat- The effect of temperature can be changed because it is lifted up.

The water pump 610 is provided on the bottom surface of the cooling water tank 100 and the pumping pipe 620 is installed in the cooling water tank 100 So that the entire cultivation water tank 300 can be cooled or warmed to a uniform temperature by pumping up the cooling water having been completely mixed and heat exchanged in the buffer tank 600. [

However, it is preferable to install the underwater pump 610 at a distance from the supply pipe 110 as much as possible, although it is illustrated as an arrangement of the underwater pump 610 near the supply pipe 110 in the city. Thus, the cooling water having a uniform temperature inside the cooling water tank 100 sufficiently heat-exchanged can be pumped up.

An oxygen supply hose 710 may be disposed on the bottom surface of the cultivation water tank 300. An oxygen injection hole may be formed in the oxygen supply hose 710 and an end of the oxygen supply hose 710 may be formed of oxygen And a piping extending from an oxygen tank (not shown) may be connected to an inlet end of the oxygen supply pump 700.

At this time, the reason why the oxygen supply pump 700 is further provided is that the dissolved oxygen amount drops sharply when the summer air temperature rises.

When the atmospheric temperature exceeds 25 ° C, the dissolved oxygen amount rapidly decreases. Therefore, when the atmospheric temperature exceeds 25 ° C, the control panel 500 detects the atmospheric temperature, and the oxygen supply pump 700 It is preferable to maintain the growth of ginseng (G) stably by supplying the amount of 0.3-0.7 L / min.

The height of the opposite side of the buffer tank 600 may be lowered or a plurality of holes may be formed at a predetermined height to be overflowed to the cooling water tank 100 while being drained.
