Description

Technology Field

[0001] The present invention relates to a tray support, and more specifically, to a tray support capable of supporting a net pot provided in a hydroponic tray spaced apart from the bottom of the tray to form a growth-active space capable of flowing and exchanging the culture solution, and stabilizing the dissolved oxygen maintenance environment of the root zone. Background Technology

[0003] Generally, hydroponics is a cultivation method that supplies water and nutrients to plant roots by circulating or storing a nutrient solution without using soil, and it establishes a plant growth environment using cultivation trays, pots, water bowls, nutrient solution supply units, and drainage units. In such hydroponics, the nutrient solution around the roots must be exchanged consistently and dissolved oxygen must be maintained; however, if the bottom of a tray or pot comes close to or contacts the bottom of a water bowl, the flow of the nutrient solution is restricted, and a stagnant area may form around the bottom of the net pot, leading to problems where the oxygen supply environment in the root zone becomes unstable. In particular, in structures where the bottom of the net pot remains submerged in the nutrient solution, it is difficult to expect direct oxygen supply from the air layer; therefore, a structure that stably ensures the flow and exchange of the nutrient solution between the bottom of the net pot and the bottom of the water bowl is important.

[0004] Accordingly, the previously disclosed Registered Patent No. 10-1210848 discloses a shelf unit for hydroponic cultivation. The said registered patent describes a structure that allows nutrient solution to be supplied and drained inside the cultivation shelf, provides a mesh installed at a predetermined height from the bottom of the cultivation shelf, and configures a tray to be placed on the mesh to secure a certain space between the tray and the bottom of the cultivation shelf. As a result, there is an advantage in that nutrient solution can flow from the bottom of the tray and a space for root growth can be secured.

[0005] However, the aforementioned prior art is close to a method of simply placing the tray on a mesh, and does not disclose a structure that individually inserts and supports the lower part of the net port provided in the tray while precisely forming a gap between the bottom surface of the net port and the bottom of the tray. Furthermore, a method of supporting the entire tray by a mesh makes it difficult to actively induce the flow and exchange of the nutrient solution in each lower area of ​​the net port, and a structure for the nutrient solution movement path that controls the flow velocity or reduces stagnation areas in response to the direction of nutrient solution flow is not specifically presented. As a result, if the nutrient solution becomes locally stagnant around the bottom surface of the net port, the environment for maintaining dissolved oxygen in the root zone may become unstable, and there is a possibility that root rot or growth deterioration may occur during long-term cultivation.

[0006] In addition, another prior art, Registered Patent No. 10-2235075, discloses a hydroponic pot. The aforementioned registered patent describes a technology configured to stably support plants by including a main body having a plurality of through holes and a structure in which a pot passes through or is fixed to the through holes. Accordingly, there is an advantage in that the plant cultivation pot can be fixed in a specific position, preventing the pot from detaching and stabilizing the arrangement of plants in a hydroponic environment.

[0007] However, the aforementioned prior art focuses on supporting and fixing the pot itself, and does not disclose a structure that forms a growth-active space capable of the flow and exchange of nutrient solution between the bottom of the pot and the bottom of the container. Furthermore, it does not present a configuration for exchanging stagnant nutrient solution around the bottom of the pot while the pot is submerged in the nutrient solution, or for stabilizing the dissolved oxygen maintenance environment of the root zone through a nutrient solution flow channel. Therefore, even if the pot is stably fixed, if the gap between the bottom of the container and the bottom of the pot and the nutrient solution flow conditions are not properly secured, a stagnant area may form at the bottom of the pot, which may lead to a deterioration of the oxygen supply environment around the roots during long-term cultivation.

[0008] As such, conventional hydroponic technologies provide structures for supporting or fixing trays or pots, but they do not sufficiently consider a structure that forms a growth-active space between the bottom of the net pot and the bottom of the water basin, allowing for the flow and exchange of nutrient solution while the bottom of the net pot is inserted and supported in the pot support hole of the support frame, and stabilizes the dissolved oxygen maintenance environment of the root zone by forming a nutrient solution flow path through the shape and arrangement of the spacing support. Therefore, there is an urgent need to develop technology that can simultaneously address stable insertion support of the net pot, precise spacing from the bottom of the water basin, smooth flow and exchange of nutrient solution, and the formation of a dissolved oxygen maintenance environment in the root zone.

[0010] (Patent Document 0001) KR 10-1210848 B1(Patent Document 0002) KR 10-2235075 B1 The problem to be solved

[0011] Accordingly, the present invention was conceived to solve the above-mentioned problems, and the purpose of the present invention is to provide a tray support that supports the lower part of the net port spaced apart from the bottom of the container, forms a growth active space capable of the flow and exchange of culture medium, and stabilizes the dissolved oxygen maintenance environment of the root zone through the culture medium movement path. means of solving the problem

[0013] To achieve this purpose, the present invention features include: a support frame (10) having a plurality of port support holes (11) formed through it so that the lower end of a net port (2) provided in a tray (1) is inserted and supported; a spacing support part (20) spaced apart from the bottom surface of the support frame (10) and provided to space the support frame (10) apart from the bottom of the container (W); and a growth active space part (30) provided to be formed as a spaced space between the bottom surface of the net port (2) and the bottom of the container (W) while the lower end of the net port (2) is inserted into the port support holes (11), thereby enabling the flow and exchange of culture solution; wherein the net port (2) is spaced apart from the bottom of the container (W) by the spacing support part (20), and the growth active space part (30) is provided to form an environment for maintaining dissolved oxygen in the root zone.

[0014] At this time, the growth active space (30) is characterized by being formed such that the bottom surface of the net pot (2) is spaced 2 to 3 cm apart from the water basin (W).

[0015] In addition, the above-mentioned spacing support member (20) is formed to protrude downward from the bottom surface of the support frame (10), and the above-mentioned spacing support member (20) is formed in a straight line and is arranged so that its length direction is parallel to the flow direction of the culture medium.

[0016] Additionally, the above-mentioned spacing support member (20) is formed to protrude downward from the bottom surface of the support frame (10), and the spacing support member (20) is formed in a droplet shape extending along the flow direction of the culture medium on a flat surface, and is formed such that the width-direction size gradually increases towards the rear end relative to the flow direction of the culture medium, and the spacing support member (20) is arranged in a first row and a second row spaced apart from each other on the bottom surface of the support frame (10), and the spacing support member (20) of the second row is arranged staggered to correspond between adjacent spacing support members (20) of the first row relative to the flow direction of the culture medium, and a culture medium movement channel (40) through which the culture medium passes is formed between the spacing support members (20) of the first row and the second row, wherein the spacing distance between adjacent spacing support members (20) of the culture medium gradually decreases as it follows the flow direction of the culture medium, so that the width-direction cross-sectional area of ​​the channel is reduced, and the culture medium is the above It is characterized by being configured so that as it passes through the culture medium movement channel (40), the flow direction is repeatedly changed as the flow velocity increases, so that it flows along a sinusoidal movement path.

[0017] Additionally, a hollow compartment (21) is formed inside the above-mentioned spacing support member (20), and an opening (22) is formed open at the bottom of the compartment (21) so that a growth-activating block (100) can be inserted therein. A plurality of perforated holes (23) are formed penetrating the side wall of the above-mentioned spacing support member (20) to connect the compartment (21) with the culture medium movement channel (40). The growth-activating block (100) is configured to be inserted and installed inside the compartment (21) through the opening (22) so as to be able to come into contact with the culture medium. The growth-activating block (100) comprises 20 to 45 parts by weight of high-temperature pre-treated shell powder, 10 to 30 parts by weight of zeolite powder, 5 to 20 parts by weight of activated carbon powder, 5 to 20 parts by weight of maifan stone powder, 5 to 15 parts by weight of loess powder, 3 to 15 parts by weight of diatomite powder, and biochar. The composition is formed by including 2 to 10 parts by weight of powder and 5 to 20 parts by weight of bentonite, wherein the bentonite acts as an inorganic binder that combines high-temperature pretreated waste shell powder, zeolite powder, activated carbon powder, maifan stone powder, red clay powder, diatomaceous earth powder, and biochar powder to maintain a block shape, and the growth-activating block (100) is characterized by being formed into a porous block structure in which fine pores are formed inside by drying or firing the composition mixture after molding. Effects of the invention

[0019] According to the above configuration and operation, the tray support according to the present invention forms a growth-active space between the bottom surface of the net port and the bottom of the water basin while the bottom of the net port is inserted and supported in the port support hole of the support frame, thereby enabling the flow and exchange of the culture medium in the lower area of ​​the net port. Accordingly, it has the effect of preventing the bottom surface of the net port from coming into close contact with the bottom of the water basin, while reducing the phenomenon of the culture medium stagnating around the root zone.

[0020] In addition, since the net port is supported from the bottom of the container by the spacing support, a space for the movement of the culture medium is secured between the bottom of the net port and the bottom of the container. Accordingly, the culture medium can move continuously along the growth active space, and new culture medium can be repeatedly supplied around the bottom of the net port.

[0021] In addition, since the growth active space is formed at a height of 2 to 3 cm between the bottom of the net pot and the bottom of the water tray, it has the effect of simultaneously securing the movable space height of the culture medium and the culture medium exchange density. Accordingly, while maintaining a fluid environment of the culture medium in the lower region of the net pot, it has the effect of forming an environment that maintains dissolved oxygen around the root zone.

[0022] In addition, since the spacing support is formed in a straight line and positioned so that its longitudinal direction is parallel to the flow direction of the culture medium, it has the effect of enabling the culture medium to move in a straight direction along the spacing support. Accordingly, flow blockage or abrupt changes in direction during the movement of the culture medium are reduced, and it has the effect of forming a continuous movement path for the culture medium along the growth active space.

[0023] In addition, due to the spacing support formed in a teardrop shape and the staggered arrangement structure of the first and second rows, the culture medium flow path forms a sinusoidal movement path, so the culture medium moves while repeatedly changing direction within the growth active space. Accordingly, it is possible to reduce the local stagnation area around the bottom of the net pot and create an environment for the movement and exchange of culture medium within the growth active space.

[0024] In addition, the nutrient solution channel is formed so that its width narrows as it follows the direction of flow, which has the effect of increasing the flow velocity during the movement of the nutrient solution. Consequently, as the nutrient solution repeatedly moves and is exchanged along the growth-active space, it is possible to maintain a nutrient solution exchange environment around the root zone.

[0025] In addition, since the growth-activating block is arranged in a state connected to the culture medium flow path through the compartments, openings, and perforations formed inside the spaced-out support member, the culture medium flows into and out of the compartments through the perforations, creating an effect of repeated contact with the growth-activating block.

[0028] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Furthermore, in describing the present invention, detailed descriptions of related known functions are omitted if they are deemed obvious to those skilled in the art and could unnecessarily obscure the essence of the invention.

[0029] FIG. 1 is a diagram showing the tray support according to an embodiment of the present invention in its entirety, FIG. 2 is a diagram showing the tray support according to an embodiment of the present invention separated, FIG. 3 is a diagram showing the tray support according to an embodiment of the present invention from the bottom view, FIG. 4 is a diagram showing the state of use of the tray support according to an embodiment of the present invention, FIG. 5 to 6 are diagrams showing the spaced support portion of the tray support according to an embodiment of the present invention, and FIG. 7 is a diagram showing the growth active block of the tray support according to an embodiment of the present invention.

[0030] The present invention relates to a tray support, which includes a support frame (10) having a plurality of port support holes (11) formed through it so that the lower part of a net port (2) provided in a tray (1) is inserted and supported to form a growth active space that allows for the flow and exchange of culture solution while supporting the lower part of the net port from the bottom of the tray (W), and so as to stabilize the dissolved oxygen maintenance environment of the root zone through the culture solution flow path; a spacing support part (20) spaced apart from the bottom surface of the support frame (10) and provided to support the support frame (10) spaced apart from the bottom of the tray (W); and a growth active space part (30) formed as a spaced space between the bottom surface of the net port (2) and the bottom of the tray (W) while the lower part of the net port (2) is inserted into the port support holes (11), thereby enabling the flow and exchange of culture solution.

[0031] The support frame (10) according to the present invention may be formed in a plate shape or a grid shape, and a plurality of port support holes (11) are formed on the upper part at regular intervals.

[0032] The above-mentioned port support hole (11) is formed with a size and shape corresponding to the outer circumference of the lower portion of the net port (2) provided in the tray (1), so that the lower portion of the net port (2) can be inserted downward through it.

[0033] Accordingly, the net port (2) is supported in a position restricted by the inner circumference of the port support hole (11), and the upper part of the net port (2) is maintained in a state of being coupled to the tray (1), while the lower part is supported by the support frame (10), thereby forming a structure. In addition, a part of the outer circumference of the net port (2) may be supported in a state of contact with the inner circumference of the port support hole (11) so as to limit shaking or positional deviation of the net port (2).

[0034] In addition, the spaced support members (20) according to the present invention are spaced apart in multiple numbers on the bottom surface of the support frame (10) and are formed to protrude downward to support the support frame (10) at a predetermined height from the bottom (W).

[0035] Accordingly, the support frame (10) is maintained in a state where it does not come into direct contact with the bottom of the basin (W), and the bottom surface of the net port (2) inserted and supported in the support frame (10) is also maintained in a state where it is spaced apart from the bottom of the basin (W). Due to this spaced structure, a growth active space (30) is formed between the bottom surface of the net port (2) and the bottom of the basin (W).

[0036] In addition, the growth active space (30) according to the present invention is a spaced space formed between the bottom of the net port (2) and the bottom of the basin (W), and is configured so that the culture solution stored in the basin (W) can move along the space.

[0037] Accordingly, the culture medium does not stagnate in the lower region of the net port (2) but flows and is exchanged along the growth active space (30), and a state is formed in which new culture medium is continuously supplied around the bottom surface of the net port (2). In addition, while the lower region of the net port (2) remains submerged in the culture medium, a path for the movement of the culture medium is secured through the growth active space (30), thereby forming a culture medium exchange environment around the root zone. Accordingly, the culture medium moving along the growth active space (30) is replaced with the existing culture medium around the bottom surface of the net port (2), thereby forming a state of repeated exchange.

[0038] In this way, the above-mentioned separation support member (20) separates and supports the net pot (2) from the bottom of the container (W), and the growth active space member (30) forms an environment in which the flow and exchange of the culture medium takes place around the bottom surface of the net pot (2). Accordingly, stagnation of the culture medium is reduced around the root zone (e.g., a root growth environment area in contact with the culture medium), and an environment for maintaining dissolved oxygen in the culture medium is formed in the lower region of the net pot (2).

[0039] And the growth active space (30) is formed with the bottom of the net pot (2) spaced 2 to 3 cm high from the water basin (W).

[0040] Accordingly, a space height is secured between the bottom surface of the net port (2) and the bottom of the basin (W) where the culture medium can move, and the bottom surface of the net port (2) is prevented from coming into close contact with the bottom of the basin (W).

[0041] In addition, the culture medium can be continuously moved along the growth active space (30) by means of a spacing structure of 2 to 3 cm in height, and the state in which the flow and exchange of the culture medium takes place around the bottom surface of the net port (2) is maintained.

[0042] Meanwhile, if the height of the growth active space (30) is formed to be less than 2 cm, the space between the bottom of the net pot (2) and the bottom of the basin (W) becomes narrow, and the cross-sectional area for the movement of the culture medium decreases. Consequently, the flow and exchange amount of the culture medium decreases, and a stagnation of the culture medium may occur around the bottom of the net pot (2). In addition, since the movement path of the culture medium is restricted, it may become difficult to form a culture medium circulation environment through the growth active space (30).

[0043] On the other hand, if the height of the growth active space (30) exceeds 3 cm, the distance between the bottom of the net pot (2) and the bottom of the basin (W) increases excessively, and the amount of culture medium retained around the lower area of ​​the net pot (2) increases, and the flow rate maintenance effect formed along the culture medium movement path may decrease. In addition, as the spatial volume of the growth active space (30) increases, the culture medium movement path is dispersed, and the culture medium exchange density around the bottom of the net pot (2) may decrease.

[0044] Accordingly, the growth active space (30) is formed such that the height between the bottom of the net pot (2) and the bottom of the basin (W) is in the range of 2 to 3 cm, thereby securing a cross-sectional area of ​​the flow path where the culture solution can continuously move along the lower area of ​​the bottom of the net pot (2), while maintaining the culture solution exchange density. Accordingly, within the growth active space (30), the environment for the flow and exchange of the culture solution is maintained, and the environment for maintaining dissolved oxygen around the root zone can be stably formed.

[0045] In FIG. 3, the above The spacing support member (20) is formed to protrude downward from the bottom surface of the support frame (10), and a plurality of spacing support members (20) are arranged spaced apart from each other along the bottom surface of the support frame (10).

[0046] The above-mentioned spacing support member (20) is formed as a straight structure along the length direction and is arranged so that the flow direction of the culture solution and the length direction are parallel to each other. Accordingly, when the culture solution stored in the container (W) moves along the growth active space (30), the culture solution can move in a straight line along the length direction of the spacing support member (20).

[0047] In addition, the spaced support member (20), formed in a straight line, is positioned so as not to intersect with the flow direction of the culture medium, thereby preventing the culture medium from colliding directly with the spaced support member (20) and blocking the flow or abruptly changing direction. Accordingly, the culture medium can move continuously along the space between the multiple spaced support members (20), and the flow path of the culture medium is maintained within the growth active space member (30).

[0048] By the linear arrangement structure as described above As in Figure 5, the ship The nutrient solution can move in one direction along the lower area of ​​the bottom of the net port (2), and a state is formed in which the culture solution stagnant around the bottom of the net port (2) is exchanged with the outer culture solution along the growth active space (30). Accordingly, a continuous culture solution exchange environment is maintained in the lower area of ​​the net port (2), and an environment for maintaining dissolved oxygen around the root zone is formed.

[0049] In FIG. 6, the above The spacing support (20) is formed to protrude downward from the bottom surface of the support frame (10) and is formed in a droplet shape that extends along the flow direction of the culture medium on a plane.

[0050] The above-mentioned spacing support (20) is formed such that, based on the flow direction of the culture medium, the front end is relatively narrow and the width gradually increases toward the rear end.

[0051] Accordingly, when the culture medium moves along the outer side of the separation support (20), the culture medium flows in while passing through the narrow front section, and forms a movement state in which the flow direction is dispersed outward around the rear section.

[0052] Additionally, the above-mentioned spacing support members (20) are arranged in a first row and a second row spaced apart from each other on the bottom surface of the support frame (10), and the spacing support members (20) of the second row are arranged staggered to correspond to the adjacent spacing support members (20) of the first row based on the flow direction of the culture medium.

[0053] Accordingly, the culture medium passing through the first row of spacing support members (20) does not move continuously in a straight line, but is guided to change its direction of movement by the second row of spacing support members (20). Additionally, since the movement path of the culture medium passing through the second row of spacing support members (20) is switched back to the direction of the first row, the culture medium moves while repeatedly changing direction along the space between the multiple spacing support members (20). Accordingly, the central movement path of the culture medium forms a curved flow shape that is repeatedly deflected in the left and right directions on a plane.

[0054] And, a culture medium passage (40) through which the culture medium passes is formed between the first and second rows of the spacing support members (20).

[0055] The above-mentioned culture medium movement channel (40) is formed such that the distance between adjacent spacing support members (20) gradually decreases as it follows the direction of culture medium flow, thereby forming a structure in which the cross-sectional area in the width direction of the channel gradually decreases. Accordingly, as the culture medium moves along the culture medium movement channel (40), the flow velocity increases due to the decrease in the cross-sectional area of ​​the channel. Consequently, a circulating flow is formed within the growth active space (30) according to the difference in the movement speed of the culture medium.

[0056] In addition, the above culture medium movement path (40) forms a curved movement path rather than a straight shape by means of a structure in which the first row and the second row of spaced support members (20) are arranged in an alternating manner.

[0057] Accordingly, the direction of flow of the culture medium is repeatedly changed during the movement process, and a state is formed in which it flows along a sinusoidal path overall. Due to this structure, the culture medium moves and is exchanged in multiple directions within the growth active space (30), and the amount of culture medium stagnating around the bottom of the net port (2) is reduced.

[0058] In this way, the culture medium moves continuously along the lower region of the net port (2) and is repeatedly exchanged within the growth active space (30), and a state is formed in which new culture medium is continuously supplied around the bottom of the net port (2). Accordingly, a culture medium flow environment is maintained around the root zone, and a dissolved oxygen maintenance environment is formed.

[0059] In FIG. 7, the above A hollow compartment (21) is formed inside the spaced support member (20). The compartment (21) may be formed to extend longitudinally along the internal space of the spaced support member (20), and an opening (22) is formed at the bottom of the compartment (21) so that a growth-activating block (100) can be inserted. Accordingly, the growth-activating block (100) can be inserted and installed into the interior of the compartment (21) through the opening (22), and if necessary, the growth-activating block (100) can be replaced or removed through the opening (22).

[0060] Additionally, a plurality of perforated holes (23) are formed through the side wall of the above-mentioned separation support member (20) to connect the compartment (21) and the culture medium movement path (40). The perforated holes (23) are formed so that the culture medium moving along the culture medium movement path (40) can flow into and out of the interior of the compartment (21), and accordingly, the culture medium can come into contact with the outer surface and internal micropores of the growth active block (100) through the perforated holes (23). Furthermore, since the culture medium moving along the culture medium movement path (40) is repeatedly exchanged with the interior of the compartment (21) through the perforated holes (23), a continuous culture medium contact environment is formed around the growth active block (100).

[0061] The above growth-activating block (100) is formed by including 20 to 45 parts by weight of high-temperature pretreated waste shell powder, 10 to 30 parts by weight of zeolite powder, 5 to 20 parts by weight of activated carbon powder, 5 to 20 parts by weight of maifan stone powder, 5 to 15 parts by weight of loess powder, 3 to 15 parts by weight of diatomite powder, 2 to 10 parts by weight of biochar powder, and 5 to 20 parts by weight of bentonite.

[0062] The above high-temperature pretreated shell powder is a porous calcium-based powder formed by washing shellfish to remove salt and then heat-treating them at a high temperature. It acts to increase the contact area with the culture medium while forming a fine pore structure inside the growth-activating block (100). Additionally, if the high-temperature pretreated shell powder is included in an amount of less than 20 parts by weight, the amount of porous structure formation is insufficient, which may reduce the effect of increasing the contact area with the culture medium. If it exceeds 45 parts by weight, the mechanical strength of the growth-activating block (100) decreases, and the possibility of wear or damage to the block surface may increase when in contact with the culture medium for a long period.

[0063] The above zeolite powder acts to increase the contact area with the culture medium while forming an ion exchange environment within the culture medium. If it is included in an amount of less than 10 parts by weight, the effect of forming a contact environment during the culture medium circulation process may be insufficient, and if it exceeds 30 parts by weight, the internal porosity of the block may increase excessively, which may lower the structural density.

[0064] The above activated carbon powder acts to increase the contact area with the culture medium through a microporous structure, and if included in an amount of less than 5 parts by weight, the formation of a porous contact structure may be insufficient, and if included in an amount exceeding 20 parts by weight, the internal bonding strength of the block may be reduced, thereby reducing molding stability.

[0065] The above maifan stone powder acts to form a structure that increases the surface area in contact with the culture medium, and the loess powder acts to increase the contact area during culture medium circulation by forming a micropore structure inside the block. In addition, the diatomite powder assists in the formation of microchannels through a porous silica-based structure, and the biochar powder acts to increase the contact pathways with the culture medium through a carbon-based porous structure.

[0066] If the above-mentioned maifan stone powder is included in an amount of less than 5 parts by weight, the formation of a surface contact structure may be insufficient, and if it exceeds 20 parts by weight, the internal density of the block may increase, leading to a decrease in the amount of pores formed. Additionally, if the loess powder is included in an amount of less than 5 parts by weight, the ability to maintain a fine pore structure may decrease, and if it exceeds 15 parts by weight, the amount of moisture absorbed by the block may increase, potentially reducing structural stability during long-term use. If the diatomite powder is included in an amount of less than 3 parts by weight, the effect of forming a fine channel may be insufficient, and if it exceeds 15 parts by weight, brittleness may increase during block molding. Furthermore, if the biochar powder is included in an amount of less than 2 parts by weight, the effect of forming a carbon-based porous structure may be insufficient, and if it exceeds 10 parts by weight, the internal bonding density of the block may decrease.

[0067] The above bentonite acts as an inorganic binder that binds together high-temperature pretreated waste shell powder, zeolite powder, activated carbon powder, maifan stone powder, red clay powder, diatomaceous earth powder, and biochar powder, thereby maintaining the external shape of the growth-activated block (100). If the above bentonite is included in an amount of less than 5 parts by weight, the binding force between each composition may be insufficient, which may reduce the block shape retention force, and if it exceeds 20 parts by weight, the internal porosity may decrease, which may reduce the effect of culture medium penetration and contact structure formation.

[0068] Additionally, the growth-activating block (100) is formed into a porous block structure in which micropores are formed inside by molding the composition mixture and then drying or firing it. In this process, a plurality of micropores may be formed inside due to the evaporation of moisture inside the composition and the formation of gaps between particles.

[0069] Accordingly, a plurality of micropores and microchannels capable of penetrating the culture medium are formed inside the growth-activating block (100), and the culture medium moving along the culture medium movement channel (40) flows into the compartment (21) through the perforated hole (23) and then repeatedly comes into contact with the internal micropores of the growth-activating block (100).

[0070] Due to the structure described above, the culture medium is repeatedly moved and exchanged along the inner and outer surfaces of the growth-activating block (100), and a circulating contact environment of the culture medium is formed within the growth-activating space (30). Accordingly, stagnation of the culture medium around the bottom surface of the net port (2) is reduced, a culture medium exchange environment around the root zone is maintained, and a dissolved oxygen maintenance environment is formed.

[0071] As described above, the detailed description of the present invention has explained the most preferred embodiment of the present invention, but various modifications are possible within the scope of the technical scope of the present invention.
