Wasabi Rhizome Production and Cultivation System

The present invention relates to a system for producing horseradish rhizomes, and to a system for producing wasabi rhizomes, which solves problems related to the lack of dissolved oxygen in water and temperature management during cultivation of wasabi, and effectively controls and controls the cultivation environment.

Wasabi is a perennial, succulent plant that grows wild in Japan, Taiwan, and Ulleungdo in Korea, and grows wild in the semi-shade areas of mountain valleys where cool and clear water flows. It has a spicy, sweet and fragrant taste and is mainly used as a spice for sashimi, sushi, and noodles. Among the components of horseradish, allyl isothiocyanate, which is abundantly present in the root, promotes digestion, promotes the synthesis of vitamin B1, inhibits the oxidation of vitamin C, suppresses abnormal fermentation in the body after meals, as an anthelmintic, antibacterial, antifungal, anticancer, insecticide, etc. It is known that the action of Recently, due to the increasing health needs of consumers, interest in natural preservatives instead of artificial food preservatives, which have safety problems such as residual toxicity and mutagenesis, is increasing, and the active ingredient of horseradish is attracting attention. Although wasabi has a high utility, consumption is increasing, but domestic cultivation is difficult and demand cannot be met. Wasabi is an environmentally sensitive crop, and its growth range is quite narrow, making it difficult to cultivate. In addition, horseradish must be cultivated for at least one year in order to be commercialized, and cultivation is difficult due to the fact that it can only be cultivated in an area where the climate is cool all year round, there is little temperature difference, and there is always clear water. For example, in Shizuoka, Japan, it is cultivated taking advantage of the natural characteristics of the semi-shaded areas of mountainous valleys. Research on wasabi cultivation has been conducted at the Cheorwon-gun Agricultural Technology Center, Gangwon-do Agricultural Research and Extension Services, and Korea University of Agriculture and Fisheries. It has been found to have a significant effect on the cultivation of wasabi. On the other hand, the technology introduced in the patent documents related to the cultivation of wasabi is 'functional hydroponic cultivation apparatus of wasabi' in Korean Patent Publication No. 10-2016-0032319, and 'water' in Korean Patent Publication No. 10-2016-0029934 Although it has been proposed as a method for forming a wasabi plantation site and wasabi 'and a 'wasabi cultivation plant' of Japanese Patent Publication No. JP5492473, the existing technologies increase the amount of dissolved oxygen in the water in the production of wasabi rhizome while producing wasabi rhizome. It is difficult to cope with the production of high-quality wasabi rhizomes due to the problem of securing the amount of dissolved oxygen required for plant growth, the temperature control of water essential for the growth of wasabi, and the inadequate environmental management required for the cultivation of wasabi.

Hereinafter, with reference to the accompanying drawings, the 'water horseradish rootstock production system' according to an embodiment of the present invention will be described in detail as follows.

According to the existing wasabi cultivation method including hydroponics cultivation, the oxygen demand required for cultivation of wasabi is not satisfied. For example, for hydroponics cultivation of wasabi, a water temperature of 11~13℃ is recommended as an appropriate cultivation temperature, but since the oxygen demand of the wasabi rhizome (root) is higher than that of other crops, in places where the water temperature is 18℃ or higher, the roots It rots easily, making efficient cultivation difficult.

In addition, hydroponics cultivation of wasabi requires a relatively large amount of water equivalent to 18 liters per second per 10a due to its characteristics, so cultivation through artificial water supply through groundwater resources is uneconomical, and when using river or valley water, water Although relatively abundant, the amount of water fluctuates greatly in other seasons, such as a shortage of water, so there is a limit to the establishment of artificial cultivation due to domestic cultivation conditions.

In particular, if gravel and massato are mixed or massato is placed in a bed in which wasabi is grown hydroponically, massato becomes hard with time and the roots of wasabi cannot extend to the lower layer of clay. In the end, horseradish lodging and growing points are submerged in water, making it difficult to produce normal rhizomes.

The water wasabi rhizome production system according to the present invention increases the utility of groundwater and increases the amount of dissolved oxygen in the water in the production of wasabi rhizomes, while the problem of securing the amount of dissolved oxygen required for the production of wasabi rhizomes, the temperature of water essential for the growth of wasabi It is proposed to produce high-quality wasabi rhizomes through integrated management of management issues and the appropriate environment required for wasabi cultivation.

Figure 3 is an example for explaining the overall structure of the water horseradish rhizome production system according to an embodiment of the present invention.

As shown in FIGS. 1 to 3, the system for producing horseradish rhizomes according to an embodiment of the present invention consists of a bed unit 100, a temperature control unit 300, and an environment control unit 400. can be

The bed unit 100 includes at least one bed 110 having a clay layer 113 , and water W1 supplied to the bed 110 through a conduit 121 through the clay layer 113 of the bed 110 . It may be configured to include a water supply unit 120 that circulates and supplies to the bed 110 , and a drain port 130 for draining water on the bed 110 to the outside when the water temperature of the water supplied to the bed 110 increases.

And, the temperature control unit 300, the house 200 covering the outside of the bed unit 100 in part or the whole, the wall 210 of the house 200 induces water drained from the drain 130 and Through this, it can be configured to form a water film on the wall surface of the house.

In addition, the environment control unit 400 may be configured to select and adjust at least one environmental parameter among aeration, sterilization, cooling, and supply of oxygen and nutrient solution of the water W1 supplied to the bed 110 .

Here, undescribed reference numeral 125 may be a 'motor pump' that pumps and supplies water W1 or discharged water W2, or pumps water discharged through a drain to a predetermined flow path. And 126 may be a 'collection well' that collects water recovered by passing raw water flowing in from the outside or circulating the bed, and has the same meaning as the storage tank 410 for storing water as shown in FIG. can be mixed.

On the other hand, the bed unit 100 installs a nutrient solution supply device (not shown) using a venturi tube just before the raw water in the bed 110 is supplied to supply trace elements to effectively supply the nutrient solution (fertilizer) required for each crop growth stage. can be configured to supply.

In addition, in order to control the flow and quantity of water in the bed 110, an isolation section (not shown) having a height of 16 to 15 cm can be installed at intervals of 10 m, and it may be desirable to configure the interval between the isolation sections to be 30 to 40 cm. .

In addition, the installation of the facility in the isolation section is configured to control the flow of water and the amount of water by installing a pipe with 5 mm drainage holes at 10 cm intervals for the drain pipe that can control the amount of water in the bed 110. have.

In addition, it may be desirable to make a drain hole in the isolation section to install a drain pipe that can remove floating matter and the like when growing wasabi to maintain cleanliness on the bed 110 .

In addition, it may be preferable to drill a hole having a diameter of 50 to 80 mm in the bottom of the end portion of the bed 110 and to install a pipe capable of controlling the water level to adjust the water level.

In addition, by placing a plurality of diaphragms (not shown) separated from each other on the bed 110, the first diaphragm is 16 cm, the second diaphragm is 15 cm, and the third diaphragm is 14 cm to configure the flow of water to flow naturally. may be desirable.

In addition, it may be desirable to configure the water collected in the upper bed 110 to fall through the drain hole and flow to the lower bed 111 in the lower layer, and at this time, the air is sucked and dropped alone to increase the amount of oxygen in the water circulation process.

In addition, in the existing wasabi plantation, gravel is laid on the lower layer and the top is filled with 20 to 35% of the massato to form a clay layer. As the horseradish could not be unloaded, there was no place to support it, and the wasabi fell down, causing the growth point to be submerged in the water or growth was inhibited, making it impossible to grow.

Accordingly, it may be preferable to form the clay layer 113 by placing the clay layer 111 on the lower bed 111 with gravel of 22 mm and filling the gravel with a thickness of about 13 mm excluding the masa or fine sand. In this way, if the sand or fine sand is removed from the clay layer in the bed 110 and the bed 110 is made of 13 mm to 22 mm gravel, some trace elements or fertilizer components may be insufficient, but a venturi tube is installed at the beginning of the bed 110. Since it can be installed and used to melt and supply fertilizer, it is possible to effectively improve the problem of the soil layer including masa and sesa.

In this way, when the bed 110 is configured and the wasabi is planted, the water W1 rich in dissolved oxygen can be directly supplied to the wasabi.

A system for producing horseradish rhizomes according to an embodiment of the present invention will be described in more detail with reference to FIGS. 1 to 3 as follows.

The bed 110 constituting the bed unit 100 may be divided into a lower bed 111 and an upper bed 112 as shown in FIG. 1 . In addition, the upper bed 112 may be configured in a layered structure on the lower bed 111 .

In addition, the lower bed 111 and the upper bed 112 may be composed of a circulation passage connected to a pipe line 121 , an overflow pipe 123 , and a recovery pipe 124 .

In addition, the bed 110 is provided with a conduit 121 for supplying water to the lower bed 110 and the upper bed 111, and a plurality of water supply ports 122 perforated at intervals in the conduit 121 are provided. It may be provided to supply oxygen-rich water to the clay layer 113 .

In addition, the water W1, which overflows from the water tank 114 of the upper bed 113, falls to the water tank 114 of the lower bed 111 while falling while forming an overflow pipe 123 at one end of the water tank 114. It may be desirable to install and configure.

In addition, the clay layer 113 of the bed 110 is configured to increase the amount of dissolved oxygen by laminating 13 to 22 mm gravel, to induce the roots of horseradish (PL) not to fall or to be submerged, and to increase the growth rate. can

The temperature control unit 300 is, as shown in FIGS. 1 and 2, a water temperature sensor 320 for detecting the current water temperature of the water W1 supplied to the bed 110, the water temperature sensor 320 that is detected from It is installed in the return pipe 124 on the side of the water supply unit 120 connected to the controller 330, the drain 130, or the drain 130 to compare and determine the detection signal with the reference value, and transmit an electrical control signal when the reference value is exceeded. It may be composed of an electromagnetic valve 310 that opens and closes the drain port 130 according to a control signal transmitted from the controller 330 .

Accordingly, when the temperature of the water W1 currently flowing on the bed 110 reaches the threshold set in the controller 330 , the solenoid valve 310 is automatically opened according to the control signal of the controller 330 and drained. The water W2 to be used is sprayed through a nozzle along the wall surface 210 of the house 200 by pumping such as a motor pump, and through this, the wall surface of the house 200 forms a water film to lower the indoor temperature of the house to reduce the indoor temperature. can be induced to keep in good condition.

For example, the optimal temperature for growing wasabi is 25℃ or lower in summer, but even if the outside temperature is high, the surrounding temperature of wasabi in the house should be maintained at around 25℃. To this end, when the temperature of the water circulating inside the bed reaches 16°C, the water is drained to the outside of the bed through the solenoid valve 310, and the drained water is sprayed on the double outer shell of the house to keep the temperature inside the facility about less than the outside air temperature. It can be adjusted to a temperature suitable for crop growth by keeping it low by 5~6℃.

The temperature control unit 300 guides the water W2 discharged through the drain 130 in this way to the wall surface 210 of the house 200, and forms a water film on the wall surface of the house so that the bed 110 is located indoors. It may be advantageous to suppress the temperature rise of

In addition, the temperature control unit 300 forms a water film on the wall of the house by spraying the water (W2) discharged through the drain port 130 to the multi-shell on the wall surface of the house (not shown), Through this, the indoor temperature in the facility can be maintained lower than the outdoor temperature, so that it can be configured to be advantageous in creating a cultivation environment suitable for the growth of wasabi.

The environment control unit 400, preferably, as shown in FIG. 2, aerates the water W1 in the storage tank 410 for recovering and storing the water W1, and sterilizes the aeration device and the water supplying oxygen. It may be desirable to have a sterilization device that is self-contained as a built-in type, or to arrange the nutrient solution 430 and oxygen generator 440 as an external type, and to be configured to include at least one of them. Accordingly, it is possible to easily manage the amount of dissolved oxygen in the water W1 essential for cultivating wasabi (PL) and various cultivation environmental parameters according to the cultivation conditions.

In addition, as shown in FIG. 2 , the environment control unit 400 may be configured to include a cooler 420 for cooling the water in the storage tank 410 that collects and stores the water W1 . Accordingly, it may be advantageous to manage the temperature of water essential for cultivating wasabi (PL) at an appropriate level.

The operation of the system for producing horseradish rhizomes according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3 .

The water wasabi rhizome production system according to an embodiment of the present invention introduces groundwater through a collecting well 126 as shown in FIG. 1 or a storage tank 410 as shown in FIG. 2 when producing wasabi rhizomes. to increase the usability of water and increase the amount of dissolved oxygen in the water in the bed 110 to promote high-quality rhizome production can manage

The wasabi rhizome production system according to an embodiment of the present invention installs a wasabi cultivation bed 110 in a house or plant factory, which can be grown stably only in a special growth environment, so that high-quality wasabi rhizome production in various areas is possible. makes it possible

The system for producing horseradish rhizomes according to an embodiment of the present invention removes the clay layer divided into the gravel layer and the masato filled in the bed 110 and facilitates oxygen supply and water flow. When the length is 3 to 8 m, the lower bed 111 is filled with 22 mm gravel-laminated thickness of 10 cm, and the upper bed 112 is filled with 13 mm gravel-laminated thickness of 5 cm, so that horseradish (PL) can grow root and grow. and can effectively grow wasabi.

The supply of water (W1) may be selected as a preferred method of supplying water from the bottom to the top, unlike the conventional method through the conduit 121 , and the bed unit 100 is disposed from the upper bed 112 to the lower portion. By applying a method in which water flows from top to bottom through the overflow pipe 123 to the bed 111, the amount of dissolved oxygen can be maximized.

In the system for producing horseradish rhizomes according to an embodiment of the present invention, in order to save water resources, the water W1 that has passed through the bed unit 100 undergoes UV disinfection, and oxygen is supplied from the water collecting well 126 or the storage tank 410. Inducing circulation of water through an aeration process for It can be automatically managed at the appropriate water temperature required for the cultivation of horseradish.

The water drained to the outside is sprayed on the wall surface 210 of the house 200 to lower the temperature in summer to form a water film, thereby lowering the temperature in the house by approximately 5 to 6 ° C, thereby producing horseradish rhizomes It is possible to manage the indoor temperature, which is essential for

The water horseradish rhizome production system according to an embodiment of the present invention removes the existing massato and uses only 13 mm to 22 mm gravel to increase the survival rate through abundant oxygen supply at the initial stage of wasabi planting by configuring the bed 110. , without putting the initial growth point in the water, the clay layer 113 filled with gravel forms a valley through which water flows, and the wasabi (PL) is planted on the ridge, thereby providing an advantageous basis for the growth of wasabi. The present invention prepares for the lack of fertilizer or trace elements that can be absorbed in the soil by not using fine sand, including mass sand, and installs a venturi tube in the bed 110 and is required through the nutrient solution 430 or fertilizer supply device. Nutrient solution and fertilizer can be effectively supplied.

On the other hand, a preferred embodiment of the water wasabi rhizome production system according to an embodiment of the present invention will be described in more detail as follows.

The system for producing horseradish rhizomes according to an embodiment of the present invention performs waterproofing treatment so that water does not leak from the water tank 114 of the lower bed 111, and water is applied to the upper and lower surfaces of the lower bed 111 and the upper bed 112. After installing the supply pipe 121, make 3-5 mm holes in the pipe at intervals of 50 to 80 cm to form a water supply port 122 to supply oxygen-rich water (W1) at around 13 ° C. The water overflowing from the water surface of the upper bed 112 makes a drop and supplies water to the lower bed 111 so that the water of the upper bed 112 flows smoothly to the lower bed 111. In this process, it is possible to ensure that the oxygen supply is stable.

The bed 110 constituting the bed unit 100 can be adjusted to the intended quantity by installing a wooden board (not shown) at each step in order to induce the flow of water step by step and adjusting the height of the wood board. In addition, in the upper bed 112, in order to control the flow of water toward the lower bed 111, holes are drilled at intervals of 10 to 15 cm at an intermediate position of the upper bed 112 to configure a drain pipe (not shown). . This allows you to control the flow of water and easily adjust the water level when cleaning or draining is required.

In the system for producing horseradish rhizomes according to an embodiment of the present invention, in the conventional cultivation method in which a clay layer is formed by mixing gravel and masa or arranging masa, oxygen supply is not smooth by masa or fine sand, but the present invention does not provide By placing 22 mm gravel with a height of 10 cm on the lower bed 111 and 13 mm gravel and 5 cm on the upper bed 112 as a clay layer, the dissolved oxygen amount on the bed 110 can be maintained at 10 ppm or more.

In addition, because the growth point of horseradish is at the base close to the ground, the growth deteriorates rapidly and rots in water occur. It is possible to increase the productivity of wasabi by providing a water level control system that adjusts the water level in response to the increase in the growth of the rhizomes of wasabi after the initial stage of growth.

The system for producing wasabi rhizomes according to an embodiment of the present invention may be designed to effectively produce wasabi rhizomes through integrated environmental management. Accordingly, an environment control unit 400 that considers wasabi growth characteristics is required. For example, by allowing water to circulate in the bed 110 and installing an aeration device and a microbubble generator or an oxygen generator in the collecting well or storage tank, water rich in dissolved oxygen is supplied to the bed 110 using groundwater to provide high quality of horseradish can be grown.

Water directly extracted from the well has dissolved oxygen (DO) of about 1 to 2 ppm, so the dissolved oxygen level is not suitable for growing wasabi, but the dissolved oxygen is supplied from the aeration device and the microbubble generator and supplied to the bed 110 . The amount of dissolved oxygen in the water (W1) used to be used can be adjusted to about 10 ppm or more so that it is suitable for cultivation of wasabi.

In addition, when the supplied water (W1) passes through the bed 110 and the temperature rises to 16°C or higher, it is automatically linked with the water film system installed on the wall surface 210 of the house 200 to reduce the temperature in the house to 5-7°C. When the water circulates, microorganisms harmful to wasabi cultivation can increase. have.

On the other hand, wasabi requires careful management in the early stages of growth. In particular, it can be said that planting methods and water management at the time of formalization determine the success or failure of cultivation. During planting of wasabi, the growing point should not go into the water. Wasabi likes water, but its growth point should always be outside of water. Based on this, when planting wasabi, it is desirable to make troughs and ridges in the clay layer 113 on the bed 110 so that the ridges rise 4-5 cm out of the water, and plant wasabi seedlings at intervals of 30 cm on it. In this case, it may be desirable to set the daytime and intertidal intervals to 30cm each as a standard.

According to the present invention, oxygen-rich water is smoothly supplied between the gravel and it is possible to keep the temperature of the water on the bed 110 constant at about 13 to 14 ° C. growth can be induced.

In addition, it may be desirable to maintain the height of the water in the bed at about half of the ridge for the initial 3 to 6 months after planting to induce the roots of wasabi to fall down stably.

In addition, select a cloudy day 2-3 months after wasabi planting (at night temperature of 20℃ or less) and drain all the water in the bed to remove impurities and debris that have accumulated so far, and the drainage time is approximately from evening to morning It was evaluated to be able to help the development of wasabi root when carried out within 12 hours and this method was carried out 5 to 10 times at intervals of 5 to 7 days.

According to the literature, wasabi is known to produce a lot at a luminous intensity of about 8,000Lux. However, if light management is performed at the initial stage of growth as before, leaves may wither and eventually a large number of crops may die, so light management is required at each stage of growth.

In the case of customized light management for each growth stage, the stability of cultivation can be ensured. Cultivation is carried out within the illuminance of 3,000 Lux for about 5 to 6 months after planting, and after 6 months when root development is stable and the growth stage enters the growth stage, about 5,000 Lux. It may be desirable to maintain the illuminance for each growth cycle.

The water wasabi rhizome production system according to the present invention increases the utility of groundwater during the production of wasabi rhizome, increases the amount of dissolved oxygen in the water in the bed, and the problem of securing the amount of dissolved oxygen required for the production of wasabi rhizome, and the amount of water essential for the growth of wasabi There is an advantage in that it is possible to produce high-quality wasabi rhizomes by integrated management of the temperature management problem and the appropriate environment required for wasabi cultivation.

As described above, the present invention has been described with reference to the embodiment shown in the drawings, but it is not limited to the embodiment and can be modified and modified within the scope without departing from the gist of the present invention. included in thought.
