Description

[Technical field]

[0001] The present invention relates to a cold / hot water hose spacing maintaining device for stably maintaining a state in which a cold / hot water hose for strawberry cultivation is installed as close as possible to the crown of the root of a strawberry seedling, which is important for the rooting and growth of the seedling when transplanting the seedling from a mother plant during strawberry cultivation, according to the seedling's growth, in order to obtain strong seedlings that are resistant to pests and diseases. [Background technology]

[0002] Generally, strawberries are cultivated in greenhouses. Because strawberries are sensitive to temperature, it is necessary to maintain a constant temperature of 20 to 23 degrees, which is suitable for growth, regardless of the outside temperature. The temperature suitable for the growth of strawberries described above must be based on the temperature at the position corresponding to the crown and root (hereinafter referred to as the "crown"), which are the growing points of the strawberry mother plant or seedlings. If an attempt is made to maintain the entire greenhouse at this temperature in order to maintain a constant temperature, not only will there be a problem of considerable energy costs, but even if the temperature of the cultivation space in the greenhouse is set to a set temperature, it will be transmitted to the crown of the strawberry through the soil in the individual pots, and will not be transmitted as an appropriate temperature. Conversely, if a temperature suitable for the crown of the strawberry is set, the temperature of the entire space in the greenhouse will become higher or lower than necessary, causing other problems such as evaporation of water from the plants or cold damage.

[0003] Recently, to solve this problem, as disclosed in Patent Document 1 or Patent Document 2, a so-called "crown heating and cooling system" has been used in which a long hot or cold water hose or pad is placed above the cultivation pot, thereby making it possible to maintain a constant temperature at the crown of the roots of seedlings grown in individual pots.

[0004] Meanwhile, strawberries can grow healthily only when the above-mentioned hot and cold water hoses and pads are kept as close as possible to the crowns of the seedlings. However, since the hot and cold water hoses made of flexible materials are long and do not have a separate alignment means, they cannot be kept parallel to the adjacent individual pots and are installed in a meandering manner. As a result, in some individual pots, the hot and cold water hoses are close to the crowns of the seedlings, while in other individual pots, the hot and cold water hoses are far away from the crowns of the seedlings. This makes it difficult to efficiently maintain a constant temperature for each of the seedlings growing in all the individual pots.

[0005] Furthermore, since strawberry cultivation or raising pots are manufactured to different sizes and intervals between individual pots due to different specifications depending on the manufacturer, a means is required to keep the hot and cold water hose for the crown of the root as close as possible to the crown of the strawberry seedlings being grown in each individual pot, regardless of the different specifications of the cultivation or raising pots.

[0006] Patent Document 3 also discloses a strawberry crown temperature control device that can accurately provide the temperature conditions necessary for plant growth and seedling raising without adversely affecting the plants. However, this is done by connecting coil-shaped piping to the bottom of each individual pot, and the manufacturing and installation costs are considerable, making it unrealizable.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are not intended to limit the present invention.

[0015] 1 to 3 show a cold / hot water hose distance maintaining device according to a first embodiment of the present invention, and FIG. 4 shows the distance maintaining device according to this embodiment in use.

[0016] As shown in Figures 1 to 4, this embodiment relates to a cold / hot water hose spacing maintainer 1 for maintaining a constant spacing between cold / hot water hoses H1, H2 installed along each of the individual pots P1, P2, P3, P4 on a strawberry cultivation pot P in which a plurality of individual pots P1, P2, P3, P4 are formed vertically and horizontally. The spacing maintainer 1 is characterized by including a spacing adjuster 30 for adjusting the spacing between a plurality of holders 10, 20 into which the cold / hot water hoses H1, H2 are inserted so that the spacing between the cold / hot water hoses H1, H2 can be adjusted according to the size of the individual pots P1, P2, P3, P4, the distance between the individual pots P1, P2, P3, P4, or the size of the strawberry mother plants or seedlings.

[0017] In this embodiment, the holders 10, 20 are formed in an open ring shape for inserting the hot and cold water hoses H1, H2, and the interval adjustment part 30 has extension pieces 32, 34 extending integrally from each holder 10, 20, which are fitted together, and male coupling protrusions 33 and female coupling holes 35 are formed at predetermined intervals, so that the interval between the holders 10, 20 on both sides can be adjusted by changing the coupling positions of the coupling protrusions 33 and the coupling holes 35.

[0018] The hot and cold water hoses H1, H2 inserted into the holders 10, 20 are folded flat when hot and cold water is not being supplied, so that they can be inserted into the inside through the narrow opening of the holders 10, 20 during the initial installation process. When hot and cold water is supplied while inserted into the holders 10, 20, the hoses H1, H2 expand into a circular cross section and maintain a stably inserted state.

[0019] In this embodiment, male coupling protrusions 33 are formed on one extension piece 32, and female coupling holes 35 are formed on the other extension piece 34. The male coupling protrusions 33 and female coupling holes 35 are formed in two rows of three at intervals of about 1 cm. The one extension piece 32 is formed in a flat plate shape, and the other extension piece 34 has bending portions 34a, 34b at the top and bottom for guiding the upper and lower parts of the one extension piece 32. Auxiliary coupling grooves 35a are formed at regular intervals in the bending portions 34a, 34b, and the one extension piece 32 has auxiliary coupling protrusions 33a formed thereon to engage with the auxiliary coupling grooves 35a.

[0020] Therefore, the spacing maintainer 1 according to this embodiment can adjust the spacing between the left and right holders 10, 20 in multiple steps in 1 cm increments according to the spacing between individual pots or the size of individual pots or the size of strawberry mother plants or seedlings, and can maintain a stable spacing adjustment state due to the three-dimensional female-male connection between the connecting protrusions 33 and auxiliary connecting protrusions 33a and the connecting holes 35 and auxiliary connecting grooves 35a.

[0021] As shown in Fig. 4, a strawberry cultivation pot P is formed with a plurality of individual pots P1, P2, P3, P4 spaced apart at a predetermined interval in the vertical and horizontal directions, and strawberry seedlings are rooted and growing in each of the individual pots P1, P2, P3, P4. The above-mentioned cold and hot water hoses H1, H2 must be kept as close as possible to the crowns of the strawberry seedlings. According to this embodiment, the cold and hot water hoses H1, H2 installed in parallel on the left and right can be kept at a constant interval by the interval maintaining device 1, so that the cold and hot water hoses H1, H2 can be stably kept as close as possible to the crowns of the strawberry seedlings in the longitudinal direction of each of the individual pots P1, P2, P3, P4.

[0022] In Fig. 4, the two individual pots P1 and P2 on the left side are each provided with one cold / hot water hose H1 and H2, and the spacing device 1 is disposed between the individual pots P1 and P2, so that the cold / hot water hoses H1 and H2 are kept parallel to each other and are brought as close as possible to the crowns of the strawberry seedlings grown in the individual pots P1 and P2, so that the temperature is optimal for the growth of the seedlings. In Fig. 4, the two individual pots P3 and P4 on the right side are each provided with two cold / hot water hoses H1 and H2, so that the temperature is kept as close as possible to the left and right sides of the crowns of the strawberry seedlings grown in the individual pots P3 and P4. Here, the spacing between the left and right holders 10 and 20 of the spacing device 1 can be adjusted as appropriate according to the size of the individual pots, the spacing between the individual pots, the size of the crowns of the strawberry seedlings, etc.

[0023] 5 and 6 show a cold / hot water hose interval maintainer 1 according to a second embodiment of the present invention. In this embodiment, the holders 10 and 20 are in an open ring shape for inserting the cold / hot water hoses H1 and H2, as in the first embodiment, and the interval adjuster 30 has extension pieces 32 and 34 extending integrally from the holders 10 and 20, which are fitted together. One extension piece 32 is flat, and the other extension piece 34 is flat and rectangular, into which the flat extension piece 32 is inserted. Elastic hook-shaped coupling protrusions 33 are formed at the top and bottom ends of one extension piece 32, and female coupling holes 35 into which the elastic hook-shaped coupling protrusions 33 are inserted are formed at the top and bottom of the other extension piece 34 at a predetermined interval in the longitudinal direction. Thus, the interval between the holders 10 and 20 can be adjusted by changing the coupling positions of the coupling protrusions 33 and the coupling holes 35.

[0024] The elastic hook-shaped coupling protrusion 33 is inserted into or removed from the coupling hole 35 by holding it with both hands and pushing or pulling it with an external force during the insertion and removal process, and the coupling protrusion 33 maintains a state of being elastically inserted into the coupling hole 35 when no external force is applied.

[0025] In the drawings, only three coupling holes 35 are formed at intervals of about 1 cm, but the present invention is not limited to this, and it goes without saying that the number of coupling holes and the intervals therebetween can be variously modified.

[0026] In addition, in the above-mentioned embodiment, the spacing maintainer has a flat shape and occupies a minimum amount of space above the cultivation pot, thereby minimizing interference with the stems and leaves of the strawberry plants. However, the present invention is not limited to this, and it goes without saying that the spacing maintainer can also be made relatively thick so as to have sufficient durability.

[0027] In the above-mentioned embodiment, the cold / hot water hose spacing maintainer of the present invention is described as being used in individual pots for growing strawberry seedlings, but the present invention is not limited to this, and it goes without saying that it can also be used for installing two rows of cold / hot water hoses H1, H2 in parallel on the left and right sides of a strawberry mother plant in a cultivation pot P' in which a mother plant for strawberry harvesting is planted, as shown in FIG. 7.
