Description

[Technical Field]

[0001] The present invention relates to a plant cultivation medium used for cultivating plants. [Background technology]

[0002] A known example of a plant cultivation medium used for plant cultivation is the plant cultivation soil disclosed in Patent Document 1. This plant cultivation soil is produced by mixing crushed food waste with wood vinegar, aging the mixture, mixing in powdered charcoal, further aging the mixture, and then mixing in powdered charcoal again.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-237083 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional cultivation soils have the following issues that need to be addressed. Specifically, fermented cultivation soils, such as those made primarily from food waste or livestock manure, require a fermentation process, which requires a long production time. Fermented cultivation soils also have issues such as odor generation and difficulty in handling. Fermented cultivation soils also have issues such as nutrients being absorbed by plants, resulting in a loss of nutrients, and the cultivation soil itself must be replaced to replenish nutrients. Some plants prefer slightly acidic soils, while others prefer slightly alkaline soils. Extremely acidic or alkaline cultivation soils are undesirable, and maintaining a near-neutral pH is preferable. However, organic cultivation soils, such as conventional cultivation soils, have issues such as difficulty in maintaining a near-neutral pH (acidity (alkalinity) within a specified range) because their acidity (alkalinity) changes after use depending on the degree of fermentation (decomposition).

[0005] The present invention has been made to solve these problems, and aims to provide a plant cultivation medium that can be produced in a short period of time, is easy to handle, and can maintain acidity within a specified range. [Means for solving the problem]

[0006] In order to solve the above problem, the plant cultivation medium described in claim 1 is a plant cultivation medium composed of peat moss, charcoal, and mountain sand, and the mixing ratio of the peat moss and the charcoal is specified so that the charcoal is in the range of 10 to 20 parts by weight per 100 parts by weight of the peat moss.

[0007] In addition, the plant cultivation medium described in claim 2 is a plant cultivation medium composed of peat moss, charcoal, and mountain sand, and the mixing ratio of the peat moss and the charcoal is specified so that the charcoal is in the range of 5 to 10 parts by weight per 100 parts by weight of the peat moss.

[0008] In addition, the plant cultivation medium described in claim 3 is a plant cultivation medium composed of peat moss, charcoal, and mountain sand, and the mixing ratio of the peat moss and the charcoal is specified so that the charcoal is in the range of 20 to 30 parts by weight per 100 parts by weight of the peat moss.

[0009] Furthermore, the plant cultivation medium described in claim 4 is a plant cultivation medium described in any one of claims 1 to 3, in which the mixing ratio of the mountain sand is specified so that the weight of the mountain sand relative to the total weight of the plant cultivation medium is within the range of 50 to 70 weight percent.

[0010] Furthermore, the plant cultivation medium described in claim 5 is a plant cultivation medium described in any one of claims 1 to 3, in which the mixing ratio of the mountain sand is specified so that the weight of the mountain sand relative to the total weight of the plant cultivation medium is within the range of 70 to 90 weight percent. [Effects of the Invention]

[0011] The plant cultivation medium of the present invention contains peat moss, charcoal, and mountain sand. Unlike conventional plant cultivation soils, this medium can be produced in a short time because it does not require a fermentation process. Furthermore, since this plant cultivation medium does not use food waste or livestock manure as raw materials, odor generation is prevented and handling is easy. Unlike conventional plant cultivation soils, this plant cultivation medium can be reused by simply disinfecting it with boiling water and then replenishing it with liquid fertilizer. Furthermore, by specifying the mixing ratio of peat moss and charcoal so that the charcoal is in the range of 10 to 20 parts by weight per 100 parts by weight of peat moss, the acidity (alkalinity) of this plant cultivation medium can be maintained within a neutral range, making it suitable for plants that prefer neutral soils.

[0012] Furthermore, according to the plant cultivation medium of the present invention, the mixing ratio of peat moss to charcoal is specified so that the ratio is within the range of 10 to 20 parts by weight of charcoal to 100 parts by weight of peat moss, thereby maintaining the acidity (alkalinity) within the acidic range, making it suitable for plants that prefer acidic soils.

[0013] Furthermore, according to the plant cultivation medium of the present invention, the mixing ratio of peat moss to charcoal is specified so that the ratio is within the range of 30 to 30 parts by weight of charcoal to 100 parts by weight of peat moss, thereby making it possible to maintain the acidity (alkalinity) within the alkaline range, making it suitable for plants that prefer alkaline environments.

[0014] Furthermore, according to the plant cultivation medium of the present invention, the mixing ratio of the mountain sand is specified so that the weight of the mountain sand is within the range of 50 to 70 weight percent of the total weight of the plant cultivation medium. Therefore, when a plant is cultivated using this plant cultivation medium, the roots of the plant can extend between the particles of the plant cultivation medium and grow sufficiently.

[0015] Furthermore, according to the plant cultivation medium of the present invention, the mixing ratio of mountain sand is specified so that the weight of mountain sand is within the range of 70 to 90 weight percent of the total weight of the plant cultivation medium. Therefore, when this plant cultivation medium is filled into a pot and a seedling is grown and then transplanted, the pot can be removed with the filled plant cultivation medium entangled around the roots of the plant (without the plant cultivation medium falling off the roots), thereby significantly improving the work efficiency of seedling raising and transplanting using this plant cultivation medium.

[Figure 2] 1 is a flowchart showing a manufacturing process 50 for manufacturing a plant cultivation medium 1. [Figure 3] 1 is a diagram showing the composition ratio of peat moss 11, charcoal 12, and mountain sand 13 that make up a plant cultivation medium 2. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the plant cultivation medium according to the present invention will be described with reference to the drawings.

[0018] Plant cultivation medium 1 is a first embodiment of the plant cultivation medium according to the present invention and is composed of peat moss 11, charcoal 12, and mountain sand 13. In this case, the mixing ratio of peat moss 11 to charcoal 12 is specified so that the weight of charcoal 12 is within the range of 10 to 20 parts by weight per 100 parts by weight of peat moss 11. Furthermore, in this plant cultivation medium 1, the mixing ratio of mountain sand 13 is specified so that the weight of mountain sand 13 relative to the total weight of plant cultivation medium 1 is within the range of 50 to 70 weight percent.

[0019] As an example, in this embodiment, as shown in Figure 1, the weight of the charcoal 12 is specified to be 15 parts by weight (15 kg) when the peat moss 11 is 100 parts by weight (100 kg), and the weight of the mountain sand 13 relative to the total weight of the plant cultivation medium 1 is specified to be 65 weight percent.

[0020] Next, a method for producing the plant cultivation medium 1 will be described with reference to a production process 50 shown in FIG.

[0021] First, 100 kg of peat moss 11 is weighed out and placed in the mixer (step 51). Next, 15 kg of smoked charcoal 12 is weighed out and placed in the mixer (step 52). Next, 210 kg of mountain sand 13 is weighed out and placed in the mixer (step 53). By weighing the mountain sand 13 in this manner, the weight of the mountain sand 13 relative to the total weight of the plant cultivation medium 1 is 65 weight percent, as shown in Figure 1. The moisture content of the mountain sand 13 is preferably within the range of 4% to 8% (prescribed range); the moisture content is measured before weighing, and adjusted to fall within the prescribed range by drying or watering as necessary.

[0022] Next, the mixer is operated to mix the added materials (step 54). This completes the plant cultivation medium 1. Next, the plant cultivation medium 1 is removed from the mixer, a predetermined amount is measured, and the mixture is filled into a storage container, flexible container, bag, or the like (step 55). Unlike conventional plant cultivation soil, this plant cultivation medium 1 does not require a fermentation process and can be produced in a short period of time. Furthermore, because this plant cultivation medium 1 does not use food waste or livestock manure as raw materials, it is possible to prevent the generation of odors and make handling easier.

[0023] Next, we will explain the method of cultivating plants using plant cultivation medium 1. This plant cultivation medium 1 is composed of peat moss 11, charcoal 12, and mountain sand 13, and contains almost no nutrients. Taking advantage of this property, when cultivating using plant cultivation medium 1, plants can be maintained in good growth condition by applying a liquid fertilizer appropriate for the type of plant. As an example, a liquid fertilizer containing ammoniacal nitrogen, nitrate nitrogen, water-soluble phosphate, water-soluble potassium, water-soluble magnesium, water-soluble manganese, and water-soluble boron is sprayed on plant cultivation medium 1 after sowing seeds or planting seedlings.

[0024] Furthermore, by mixing the peat moss 11 and charcoal 12 in the above ratio (see Figure 1), the plant cultivation medium 1 exhibits a neutral acidity (alkalinity), and the neutral state is maintained by preventing changes in acidity due to fermentation of the plant cultivation medium 1 itself. As a result, this plant cultivation medium 1 can support many types of plants in good growth condition. Furthermore, in this plant cultivation medium 1, the mixing ratio of mountain sand 13 to the total weight of the plant cultivation medium 1 is the above ratio (see Figure 1). With this ratio, an appropriate amount of space is created between the particles of the plant cultivation medium 1, allowing plant roots to extend into these spaces and achieve sufficient root growth.

[0025] Furthermore, unlike conventional plant cultivation soil, this plant cultivation medium 1 can be easily treated with methods such as disinfection with boiling water and then sprayed with liquid fertilizer, allowing the plant cultivation medium 1 to be used repeatedly to cultivate new plants.

[0026] Thus, this plant cultivation medium 1, which contains peat moss 11, charcoal 12, and mountain sand 13, can be produced in a short time because it does not require a fermentation process, unlike conventional plant cultivation soil. Furthermore, this plant cultivation medium 1 does not use food waste or livestock manure as raw materials, preventing odor generation and making it easy to handle. Furthermore, unlike conventional plant cultivation soil, this plant cultivation medium 1 can be reused by simply disinfecting it with hot water and replenishing it with liquid fertilizer. Furthermore, this plant cultivation medium 1 maintains its acidity (alkalinity) within a neutral range by specifying the mixing ratio of peat moss 11 to charcoal 12 so that the weight of charcoal 12 per 100 parts by weight of peat moss 11 is within the range of 10 to 20 parts by weight, thereby making it suitable for plants that prefer neutral soils.

[0027] Furthermore, according to this plant cultivation medium 1, the mixing ratio is specified so that the weight of the mountain sand 13 relative to the total weight of the plant cultivation medium 1 is within the range of 50 to 70 weight percent, which allows the roots of the plant to extend between the particles of the plant cultivation medium 1 and grow sufficiently.

[0028] In the plant cultivation medium 1, the mixing ratio of the peat moss 11 and the charcoal 12 can be arbitrarily set within a range of 10 to 20 parts by weight of the charcoal 12 to 100 parts by weight of the peat moss 11. The mixing ratio of the mountain sand 13 can also be arbitrarily set within a range of 50 to 70 weight percent of the total weight of the plant cultivation medium 1. The plant cultivation medium 1 may also contain additives other than the peat moss 11, the charcoal 12, and the mountain sand 13.

[0029] Next, a plant cultivation medium 2 as a second embodiment of the plant cultivation medium will be described. The plant cultivation medium 2 is composed of peat moss 11, charcoal 12, and mountain sand 13. As shown in FIG. 3, the mixing ratio of peat moss 11 to charcoal 12 in this plant cultivation medium 2 is also specified so that the weight of charcoal 12 relative to 100 parts by weight of peat moss 11 is within the range of 10 to 20 parts by weight. Meanwhile, in this plant cultivation medium 2, the mixing ratio of mountain sand 13 relative to the total weight of the plant cultivation medium 2 is specified so that the weight of mountain sand 13 relative to the total weight of the plant cultivation medium 2 is within the range of 70 to 90 weight percent. In this embodiment, as shown in FIG. 3, the weight of charcoal 12 is specified to be 15 parts by weight relative to 100 parts by weight (100 kg) of peat moss 11, and the mixing ratio of mountain sand 13 relative to the total weight of the plant cultivation medium 2 is specified so that the weight of mountain sand 13 relative to the total weight of the plant cultivation medium 2 is 80 weight percent (450 kg).

[0030] According to this plant cultivation medium 2, by specifying the mixing ratio of mountain sand 13 in this way, when this plant cultivation medium 2 is filled into a seedling pot and the seedling is grown and then transplanted, the seedling pot can be removed while the plant cultivation medium 2 filled in the seedling pot is entangled with the roots of the plant (without the plant cultivation medium 2 falling off the roots), thereby significantly improving the work efficiency of seedling raising and transplanting using this plant cultivation medium 2.

[0031] In the plant cultivation medium 2, the mixing ratio of the peat moss 11 and the charcoal 12 can be arbitrarily set within a range of 10 to 20 parts by weight of the charcoal 12 to 100 parts by weight of the peat moss 11. The mixing ratio of the mountain sand 13 can also be arbitrarily set within a range of 70 to 90 weight percent of the total weight of the plant cultivation medium 2. The plant cultivation medium 2 may also contain additives other than the peat moss 11, the charcoal 12, and the mountain sand 13.

[0032] Next, a plant cultivation medium 3 will be described as a third embodiment of the plant cultivation medium. The plant cultivation medium 3 is composed of peat moss 11, charcoal 12, and mountain sand 13. As shown in FIG. 4, the mixing ratio of peat moss 11 to charcoal 12 is specified so that the weight of charcoal 12 is within the range of 5 to 10 parts by weight per 100 parts by weight of peat moss 11. Furthermore, in this plant cultivation medium 3, the mixing ratio of mountain sand 13 is specified so that the weight of mountain sand 13 is within the range of 50 to 70 weight percent of the total weight of the plant cultivation medium 3. In this embodiment, as shown in FIG. 4, the weight of charcoal 12 is specified so that the weight of mountain sand 13 is 6 parts by weight per 100 parts by weight (100 kg) of peat moss 11, and the mixing ratio of mountain sand 13 is specified so that the weight of mountain sand 13 is 65 weight percent (370 kg) of the total weight of the plant cultivation medium 3.

[0033] According to this plant cultivation medium 3, the mixing ratio of peat moss 11 and charcoal 12 is specified so that the weight of charcoal 12 per 100 parts by weight of peat moss 11 is within the range of 5 to 10 parts by weight. As a result, the acidity (alkalinity) of the plant cultivation medium 3 can be maintained within the acidic range since the proportion of acidic peat moss 11 is high (the proportion of charcoal 12 is low), making it suitable for plants that prefer acidity.

[0034] In the plant cultivation medium 3, the mixing ratio of peat moss 11 to charcoal 12 can be arbitrarily specified within a range of 5 to 10 parts by weight of charcoal 12 per 100 parts by weight of peat moss 11. The mixing ratio of mountain sand 13 can also be arbitrarily specified within a range of 50 to 70 weight percent of the total weight of the plant cultivation medium 3. The mixing ratio of mountain sand 13 can also be arbitrarily specified within a range of 70 to 90 weight percent of the total weight of the plant cultivation medium 3. The plant cultivation medium 3 may also contain additives other than peat moss 11, charcoal 12, and mountain sand 13.

[0035] Next, a fourth embodiment of the plant cultivation medium, a plant cultivation medium 4, will be described. The plant cultivation medium 4 contains peat moss 11, charcoal 12, and mountain sand 13. As shown in FIG. 5, the mixing ratio of the peat moss 11 and the charcoal 12 is specified so that the weight of the charcoal 12 is within the range of 20 to 30 parts by weight per 100 parts by weight of peat moss 11. Furthermore, in this plant cultivation medium 4, the mixing ratio of the mountain sand 13 is specified so that the weight of the mountain sand 13 is within the range of 50 to 70 weight percent of the total weight of the plant cultivation medium 4. In this embodiment, as shown in FIG. 5, the weight of the charcoal 12 is specified to be 15 parts by weight per 100 parts by weight (100 kg) of peat moss 11, and the mixing ratio of the mountain sand 13 is specified so that the weight of the mountain sand 13 is 65 weight percent (370 kg) of the total weight of the plant cultivation medium 4.

[0036] In this plant cultivation medium 4, the mixing ratio of peat moss 11 to charcoal 12 is specified so that the weight of charcoal 12 per 100 parts by weight of peat moss 11 is within the range of 20 to 30 parts by weight. As a result, the acidity (alkalinity) of the plant cultivation medium 4 can be maintained within the alkaline range because the proportion of acidic peat moss 11 is low (the proportion of charcoal 12 is high), making it suitable for plants that prefer alkaline environments.

[0037] In the plant cultivation medium 4, the mixing ratio of peat moss 11 to charcoal 12 can be arbitrarily specified within a range of 20 to 30 parts by weight of charcoal 12 per 100 parts by weight of peat moss 11. The mixing ratio of mountain sand 13 can also be arbitrarily specified within a range of 50 to 70 weight percent of the total weight of the plant cultivation medium 4. Furthermore, the mixing ratio of mountain sand 13 can also be arbitrarily specified within a range of 70 to 90 weight percent of the total weight of the plant cultivation medium 4. The plant cultivation medium 4 may also contain additives other than peat moss 11, charcoal 12, and mountain sand 13. [Explanation of symbols]
