[0002] Generally, when growing seedlings for the purpose of cultivating trees, seeds and soil are placed in a container called a seedling pot for cultivation. After placing the soil and seeds described above into such a seedling pot, they are grown to produce a specific seedling. The grown seedling becomes a sapling and is planted in the ground.

[0003] The seedling pot for growing the above seedling includes a pot for accommodating the seedling. This pot has a specific diameter and height, and the seedling is placed inside the seedling pot.

[0004] However, in the case of such conventional technology, the height of the seedling varies depending on the type of seedling. Since the seedling pot is formed as a single unit and has a specific diameter and height, there was a problem of increased costs because multiple seedling pots of various heights had to be provided to accommodate seedlings of various heights.

[0005] In addition, the above-mentioned conventional technology had a problem of reduced work efficiency because the seedlings had to be separated from the seedling pots and then planted in the soil.

[0018] In the above, the second stopper (230) or the third stopper (330) is formed such that its radial length decreases as it goes downward.

[0019] In the above, the base port body (110) of the base port (100) is formed to be inclined in a direction in which the diameter decreases as it goes downward, and the inclination angle (θ1) of the base port body (110) is 0.5 to 1.5 degrees with respect to the vertical axis, and the connection port body (210) of the connection port (200) is formed to be inclined in a direction in which the diameter decreases as it goes downward, and the inclination angle (θ2) of the connection port body (210) is 0.5 to 1.5 degrees with respect to the vertical axis.

Specific details for implementing the invention

[0031] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In this process, the thickness of lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of explanation.

[0032] Furthermore, the terms described below are defined in consideration of their functions within the present invention, and these may vary depending on the intent or practice of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0033] In addition, the following embodiments are not intended to limit the scope of the present invention but are merely exemplary details of the components presented in the claims of the present invention, and embodiments including components that are included in the technical concept throughout the specification of the present invention and are substitutable as equivalents for the components of the claims may be included in the scope of the present invention.

[0035] A seedling pot (10) according to one embodiment of the present invention includes a seedling pot (300) on which a cultivated seedling is placed as shown in FIGS. 1 to 8, a connecting pot (200) into which the seedling pot (300) is inserted, and a base pot (100) in which the connecting pot (200) is placed. That is, the connecting pot (200) is placed inside the base pot (100), and the seedling pot (300) is placed inside the connecting pot (200). At this time, the connecting pot (200) is provided with one or more of the following, so that the length can be adjusted to fit the size of the seedling.

[0036] That is, if the height of the seedling is large, the above connection ports can be provided in multiple numbers to accommodate the height of the seedling, and conversely, if the height of the seedling is low, the number of connection ports can be reduced to accommodate the height of the seedling.

[0037] According to the present invention, since there is no need to provide multiple seedling pots of various heights, cost reduction is possible.

[0038] The above base port (100) includes a base port body (110) which has a hollow shape and has upper and lower side openings. A first inward flange (120) is formed by being inwardly bent at the bottom of the base port body (110).

[0039] The above connection port (200) includes a connection port body (210) that has a hollow shape and has upper and lower side openings. A second outward flange (220) is formed by being bent outward at the top of the connection port body (210). Additionally, a second inward flange (240) is formed by being bent inward at the bottom of the connection port body (210).

[0040] The above seedling pot (300) includes a seedling pot body (310) that is hollow and has an open top. A third outward flange (320) is formed by outwardly bending the top of the seedling pot body (310).

[0041] At this time, after the connection port (200) is inserted into the base port (100), the second outward flange (220) is caught on the upper surface of the first inward flange (140) of the base port (100). Accordingly, after the connection port (100) is inserted into the base port (200), the upper part of the connection port (100) is caught on the lower part of the base port (200).

[0042] Additionally, after the seedling port (300) is inserted into the connection port (200), the third outward flange (320) is caught on the upper surface of the second inward flange (240) of the connection port (200). Accordingly, after the seedling port (300) is inserted into the connection port (200), the upper end of the seedling port (300) is caught on the lower end of the connection port (200).

[0043] It has already been explained that the base port (100), the connection port (200), and the seedling port (300) are combined with each other by this configuration, and the height can be increased by increasing the number of the connection ports (200).

[0044] Meanwhile, a second stopper (230) protrudes from the outer surface of the connection port body (210), and a third stopper (330) protrudes from the outer surface of the seedling port body (310). With this configuration, the connection port (200) is inserted into the base port (100), and after the second outward flange (220) is caught on the upper surface of the first inward flange (140), the second stopper (230) contacts the lower surface of the first inward flange (140), thereby prohibiting the upward movement of the connection port (200).

[0045] Additionally, after the seedling pot (300) is inserted into the connecting pot (200) and the third outward flange (320) is caught on the upper surface of the second inward flange (240), the third stopper (330) contacts the lower surface of the second inward flange (240), thereby prohibiting the upward movement of the seedling pot (300). With this configuration, the seedling pot of the present invention can have structural stability.

[0046] The second outward flange (220) is formed such that a plurality of them are arranged circumferentially on the upper part of the connection port body (210) and spaced apart at a certain angle. At this time, the second stopper (230) is arranged between the second outward flanges (220).

[0047] Similarly, the third outward flange (320) is formed such that a plurality of them are arranged circumferentially on the upper part of the seedling pot body (310) and spaced apart at a certain angle. At this time, the third stopper (330) is placed between the third outward flanges (320).

[0048] To this end, the relationship between the outer end diameter (D21) of the second outward flange (220), the inner end diameter (D12-2) of the first inward flange (140), and the diameter (D12-1) of the contact point between the first inward flange (140) and the base port body (110) is D12-1 < D21 <D12-2인 것이 바람직하다.

[0049] That is, the outer end diameter (D21) of the second outward flange (220) must be larger than the inner end diameter (D12-2) of the first inward flange (140) so that the second outward flange (220) is caught on the first inward flange (140). At this time, the outer end diameter (D21) of the second outward flange (220) must be smaller than the diameter (D12-1) of the contact point between the first inward flange (140) and the base port body (110) so that the connection port (200) can be inserted into the base port (100).

[0050] At this time, the outer diameter (D22) of the second stopper (230) is larger than the inner end diameter (D12-2) of the first inward flange (140). Therefore, even if the connection port (200) rises, the second stopper (230) contacts the first inward flange (140) to prevent it from rising further.

[0051] Meanwhile, the second stopper (230) is formed such that its radial length decreases as it moves downward. Due to this shape, when the second stopper (230) comes into contact with the first inward flange (140), the connection port body (210) or the base port body (110) is elastically deformed, causing the second stopper (230) to pass through the first inward flange (120). However, when moving in the opposite direction, that is, upward, the second stopper (230) comes into contact with the first inward flange (140), thereby prohibiting upward movement.

[0052] In addition, the relationship between the outer end diameter (D31) of the third outward flange (320), the inner end diameter (D22-2) of the second inward flange (240), and the diameter (D22-1) of the contact point between the second inward flange (240) and the connection port body (210) is D22-1 < D31 <D22-2이다.

[0053] That is, the outer end diameter (D31) of the third outward flange (320) must be larger than the inner end diameter (D22-2) of the second inward flange (240) so that the third outward flange (320) is engaged with the second inward flange (240).

[0054] In addition, the outer end diameter (D31) of the third outward flange (320) must be smaller than the diameter (D22-1) of the contact point between the second inward flange (240) and the connecting port body (210) so that the seedling port (300) can be inserted into the connecting port (200).

[0055] Meanwhile, the outer diameter (D32) of the third stopper (330) is larger than the inner end diameter (D22-2) of the second inward flange (240).

[0056] Due to this shape, when the third stopper (330) comes into contact with the second inward flange (240), the seedling pot body (310) or the connecting pot body (210) is elastically deformed, causing the third stopper (330) to pass through the second inward flange (240). However, when moving in the opposite direction, that is, upward, the third stopper (330) comes into contact with the second inward flange (240), thereby prohibiting upward movement.

[0057] As described above, the connection port (200) is inserted into the base port (100), and a seedling port (300) is placed inside the connection port (200). At this time, it is also possible to form the base port (100) and the connection port (200) at an angle so that they can slide more smoothly. That is, the base port body (110) of the base port (100) is formed at an angle such that the diameter decreases as it goes downward, and the angle of inclination (θ1) of the base port body (110) is formed to be 0.5 to 1.5 degrees with respect to the vertical axis.

[0058] In addition, the connection port body (210) of the connection port (200) is also formed to be inclined in a direction in which the diameter decreases as it goes downward, and the inclination angle (θ2) of the connection port body (210) is formed to be 0.5 to 1.5 degrees with respect to the vertical axis.

[0059] The base port (100) and the connection port (200) having such a shape can be more smoothly coupled to each other.

[0060] Meanwhile, the base port (100), connection port (200), or seedling mot (300) may also be made of a biodegradable material. For this purpose, it is also possible to use a mixture of PHA (polyhydroxyalkanoate) and PLA (poly lactic acid) materials in a specific ratio.

[0061] According to the present invention, by utilizing a mixture of polyhydroxyalkanoates and polylactic acid, biodegradability is possible through soil moisture and microbial activity, and the pot size can be utilized in various sizes ranging from a minimum of 70 mm to a maximum of 1,000 mm so as to be applicable to various soil environments ranging from arid to tropical climates.

[0062] In other words, according to the present invention, a process of finding an appropriate mixing ratio that allows the shape to be maintained even during a nursery period of more than 9 months underwater in a bottom-watering nursery facility and fragmented after maintaining the shape in the soil for more than 6 months after planting, and a problem of uniformly moving moisture from the bottom to the top of pots of various lengths using capillary action to suit a bottom-watering environment so that plants can utilize it, and a planting depth of various shapes suitable for various soil environments can be provided.

[0063] To this end, as described above, it becomes possible to combine the high degradation rate of PHA with the structural stability of PLA through a suitable mixing ratio. Furthermore, by developing a multi-stage structure according to the present invention, shapes capable of providing various port depths can be developed by adding or removing each stage.

[0064] With this invention, the rooting rate and survival rate of seedlings can be increased by planting the pot in the soil compared to conventional PP seedling pots.

[0065] In addition, by combining it with a bottom watering system, it can shorten the existing nursery process for pine trees by at least one year, thereby increasing the space efficiency of the nursery and enabling a system for mass nursery production and mass supply in a short period.

[0066] In addition, by enhancing the convenience of transporting and utilizing seedlings, it is possible to transition the existing nursery system centered on mountain-based nurseries to a hub nursery system, thereby improving effective nursery management and the efficiency of utilizing specialized personnel.

[0067] Furthermore, it can be utilized as a universal technology applicable not only to the Korean Peninsula but also to various countries requiring nursery care and forestation, such as Mongolia, Central Asian countries, Southeast Asia, and Latin America.

[0068] Meanwhile, it is also possible to form a first outward flange (120) on the upper part of the base port body (110). That is, an outward flange is formed on the connection port body (210) and the seedling port body (310), respectively, and such an outward flange can also be formed on the base port body (110).

[0069] Additionally, it is possible to form a plurality of development slots that are open to a specific width on the outer surface of the base port body (110) or the connection port body (210). That is, an open slot (350) is formed in the seedling port body (310), and such an open slot can be formed on the outer surface of the base port body (110) or the connection port body (210).

[0070] As described above, the above connection port (200) may be provided in one or more multiple quantities. In FIG. 1, two connection ports (200) are shown, but this is merely an example to explain the present invention, and as previously explained, the connection port (200) can be provided in one or multiple quantities depending on the height of the seedling and adjusted according to the height of the seedling.

[0071] The following describes a method for growing seedlings using the seedling pot of the present invention described above. First, a connecting pot (200) is inserted into a base pot (100), and a seedling pot (300) is inserted into the connecting pot (200). At this time, the connecting pot (200) is inserted into the base pot (100), and the second outward flange (220) is caught on the upper surface of the first inward flange (140). Subsequently, the second stopper (230) contacts the lower surface of the first inward flange (140), thereby prohibiting the upward movement of the connecting pot (200).

[0072] Additionally, after the seedling pot (300) is inserted into the connecting pot (200) and the third outward flange (320) is caught on the upper surface of the second inward flange (240), the third stopper (330) contacts the lower surface of the second inward flange (240), thereby prohibiting the upward movement of the seedling pot (300). Subsequently, the height of the seedling pot is adjusted by selecting the number of connecting pots (200) to match the height of the seedling to be planted.

[0073] Meanwhile, when the connection port (200) is inserted into the base port (100), the second stopper (230) passes through the first inward flange (140) while the connection port body (210) or the base port body (110) is elastically deformed while the second stopper (230) is engaged with the first inward flange (140). Subsequently, the second outward flange (220) is engaged with the first inward flange (140).

[0074] Additionally, when the seedling pot (300) is inserted into the connecting pot (200), the third stopper (330) passes through the second inward flange (240) while the connecting pot body (210) or the seedling pot body (310) is elastically deformed while the third stopper (330) is engaged with the second inward flange (240). Subsequently, the third outward flange (320) engages with the second inward flange (240). After going through these steps, the seedling is placed in the seedling pot (300) and cultivated.

[0075] At this time, the cultivated seedlings are planted in the soil while remaining in the seedling pots, without being separated from the seedling pots of the present invention. This is because the seedling pots of the present invention are biodegradable and decompose naturally.

[0077] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically explaining the invention, and the invention is not limited thereto. It is evident that modifications or improvements can be made by those skilled in the art within the technical scope of the invention.

[0079] All simple variations or modifications of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the appended claims. Explanation of the symbols
