TECHNICAL FIELD

[0001] The present invention relates to a solid medium containing coconut shell, and more particularly, to a solid medium containing coconut shell capable of effectively adjusting and solving problems of moisturizing power and dehydration, etc. BACKGROUND

[0002] Nutrient solution cultivation is a method of cultivating crops in a soilless state without using soil, supporting and fixing crops by various methods, and cultivating crops using a culture solution dissolved at an appropriate concentration according to the necessary elements required for the growth of crops, which is called water cultivation, solution cultivation, soilless cultivation, hydroponic cultivation, etc.

[0003] According to the type of medium, the above-mentioned nutrient solution cultivation is classified into air cultivation, water cultivation, and solid medium cultivation, and the most widely used solid medium cultivation is a cultivation method of supporting crops and supplying nutrient solution using a solid medium (hereinafter, referred to as "cultivation soil") manufactured from sand, perlite, rock wool, gravel, coarse bark, and charred carbon instead of natural soil.

[0004] As the above-mentioned solid medium, there are rock wool medium, coconut shell medium, perlite medium, etc. It is a medium manufactured using double-layered waste coconut shell fibers. It has excellent moisturizing power, and air is freely circulated. The old medium after use has the advantages of natural decomposition as an organic matter, and has recently been spotlighted as a solid medium.

[0005] However, since it has excellent moisturizing power, it can have problems in dehydration, etc., and it can be difficult to maintain the concentration of nutrient solution. SUMMARY

[0006] TECHNICAL PROBLEM Therefore, the present invention is to solve the problem of providing a solid medium capable of effectively adjusting and solving problems of moisturizing power and dehydration, etc.

[0018] Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. However, these are merely examples, and the present invention is not limited thereto.

[0019] In describing this invention, detailed descriptions of well-known techniques related to this invention are omitted where such detailed descriptions would obscure the essence of the invention. Furthermore, the terminology described below is defined in consideration of the functionality within this invention and may vary depending on the intent or practice of the user or operator. Therefore, its definitions should be based on the entirety of this specification.

[0020] The technical concept of this invention is defined by the claims. The following embodiments are merely a way to effectively illustrate the technical concept of this invention to those skilled in the art.

[0021] Figure 1 This is a cross-sectional view of a solid culture medium according to an embodiment of the present invention.

[0022] refer to Figure 1 This is a cross-sectional view of a solid culture medium according to an embodiment of the present invention.

[0023] like Figure 1 As shown, the solid culture medium according to the present invention is in the form of a regular hexahedron and consists of two layers 100 and 200. The first layer 100 comprises coconut husk chips and coconut shell fibers with a size of 7 to 15 mm, located below the solid culture medium. The second layer 200 is coconut shell powder, composed of fine powder filtered through a sieve with a mesh size of 30 SQR per inch (30 SQR for 1 Inch standard mesh). Here, "30 SQR (30 SQR for 1 Inch standard mesh)" refers to filtering very small particles through a mesh (sieve) with 30 quadrilateral holes per inch when filtering fine particles using a one-inch standard mesh.

[0024] At this point, the weight ratio of the first layer to the second layer is 7:3.

[0025] In particular, the present invention maintains the moisture content by forming a dense powdery second layer on the upper side, and forms a fragmented coconut coir with larger particles than the powder in the second layer below it, thereby facilitating dehydration.

[0026] Furthermore, in this invention, as shown in Table 1 below, the coconut shell fragments of the first layer 100 are configured in three sizes.

[0027] [Table 1]

[0028] This invention, through its structure, simultaneously possesses dehydration and moisture retention capabilities, which is highly advantageous for moisture content and EC management. In particular, the invention utilizes both shavings and coconut fiber at the lower end, thus enabling rapid water absorption and drainage, improving visibility. Furthermore, it also functions to stably maintain the lower layer structure during compression.

[0029] In embodiments of the present invention, the aforementioned fibrous material has a length of 5 mm to 50 mm and a thickness of 0.1 mm to 0.3 mm, and the moisture content is maintained at 10% to 15% of the fibrous material weight. If the moisture content is lower than the aforementioned level, it will absorb water excessively; conversely, if the moisture content is higher than the aforementioned level, there will be a problem of reduced mechanical stability.

[0030] Figure 2 and Figure 3 These are cross-sectional views of the culture medium of the present invention and a coconut coir-based solid culture medium according to the prior art, respectively. Additionally, Figure 4 and Figure 5 The images show photographs of actual use of the culture medium according to the present invention and a coconut coir-based solid culture medium according to the prior art.

[0031] Reference Figures 2 to 5 It is understood that the solid culture medium according to the present invention has a multilayer structure.

[0032] In particular, refer to Figure 4 and Figure 5 According to the present invention, when the upper part contains a solid culture medium containing coconut shell powder, it can be confirmed that the fine hairy roots and coarse roots in the upper part grow well together.

[0033] Figure 6 and Figure 7 A graph showing the experimental results for moisture content.

[0034] Reference Figure 6 and Figure 7 In the case of the solid culture medium according to the present invention, it takes 4 minutes and 40 seconds from the time water is supplied to the solid culture medium until the first waste liquid is discharged, while the existing solid culture medium only takes 55 seconds.

[0035] Furthermore, when the supply is 600ml, the waste liquid volume after 9 minutes is 150ml in this invention, while it is a full 400ml in existing culture media.

[0036] The above results indicate that the multilayer culture medium according to the present invention is highly efficient in nutrient solution absorption after nutrient supply.

[0037] Figure 8 It is a graph summarizing the time it takes to reach maximum moisture content.

[0038] exist Figure 8 The upper figure shows the water content analysis results for a culture medium according to the prior art, and the lower figure shows the water content analysis results for a multilayer culture medium according to the present invention.

[0039] Reference Figure 8 It can be seen that, compared with existing culture media, the culture media of the present invention preferentially achieves the maximum water content at 45 minutes.

[0040] As described above, the present invention comprises multiple layers of coconut coir, wherein the layer with larger coconut coir size (fragment layer) forms the lower layer and the layer with smaller coconut coir size (dust layer) forms the upper layer. This provides the advantage of effectively managing excellent moisture content, dehydration, and EC (excessive moisture content).
