Description

Application for application of Article 30, Paragraph 2 of the Patent Act filed Minato Yamaguchi Godo Shimbun Co., Ltd. (published in the daily Minato Shimbun) June 22, 2020

The present invention relates to a fertilizing body and a method for manufacturing the fertilizing body.

In recent years, algae (including seaweed) are decreasing in coastal areas and rivers, and rocky shores are becoming increasingly eroded. In the past, iron fulvic acid, which is produced in the humus soil of forests, flowed in from rivers as a nutrient, but the amount has decreased in recent years, and there is no longer enough nutrients for fish and seaweed. be. As a result, spawning sites for fish such as sea bream will decrease, leading to a decline in fish numbers. Patent Document 1 discloses an aquatic environment conservation material in which a divalent iron-containing substance and a humic-containing substance are present, and iron fulvic acid is eluted when the material is submerged in water.

Japanese Patent Application Publication No. 2006-81457

Algae live in a variety of environments, including coastal sandy mud and rocky areas. However, due to its structure, the aquatic environment conservation material as disclosed in Patent Document 1 is difficult to use for the growth of eelgrass, which grows naturally in coastal sandy mudlands at depths of 1 to several meters. It becomes. Moreover, since it is a large structure, it takes time and effort to arrange it.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fertilizing body and a method for manufacturing the fertilizing body, which have a small structure and can supply algae nutrients into the sea regardless of the location, such as coastal sandy mud areas or rocky areas. do.

The fertilizer application body of the present invention contains at least iron fulvic acid (divalent) produced by reacting ferrous sulfate with fulvic acid, and at least one of cement, sand, and gravel.

The fertilizer application body of the present invention contains iron fulvic acid (divalent), cement, sand, and gravel.

The fertilizer body of the present invention contains at least iron fulvic acid (divalent) produced by reacting ferrous sulfate with fulvic acid, has a maximum width of 1 to 10 cm, and weighs 20 to 20 cm. 1000g, and its specific gravity is 3 or more.

The method for producing a fertilization body of the present invention includes producing a mixture of at least one of cement, sand, and gravel combined with water, and reacting at least ferrous sulfate with fulvic acid to produce ferrous ferric acid (ferrous sulfate). divalent) with the mixture.

According to the present invention, nutrients for algae can be supplied into water with a small structure regardless of the location, such as coastal sandy mud areas or rocky areas.

An embodiment of the present invention will be described in detail below with reference to the drawings. The configuration, shape, components, etc. described below are examples for explanation, and can be changed as appropriate depending on the specifications of the fertilization body, artificial reef, etc. Hereinafter, corresponding elements in all drawings will be denoted by the same reference numerals, and redundant explanation will be omitted. Moreover, although the sea and the river are illustrated below to represent the water, the fertilizing body 1 may be used in water other than the sea and the river.

First, referring to FIG. 1, the fertilizing body 1 will be explained. FIG. 1 is a perspective view of a fertilizing body according to an embodiment of the present invention. The fertilizing body 1 includes at least one of granular (for example, 3 mm to 5 mm in diameter) stones such as cement, sand, silicon, diatomaceous earth, and gravel, and iron fulvic acid (in the divalent iron state). . In particular, it is preferable to contain at least cement, sand, gravel (granular stone), and iron fulvic acid (in the form of divalent iron). This makes it possible to slowly supply nutrients such as iron fulvic acid (in the divalent iron state) into the water over a long period of time, for example 3 to 10 years or more.

The reason why it is preferable to allow the fertilized body 1 to elute nutrients over a long period of time is because algae grow during a certain period of the year, for example from November to March. It is preferable that the fertilizing body 1 is capable of supplying nutrients for one year or more so that nutrients can be eluted stably over a long period of time during the algae growth period in any climate or region. In addition, if nutrients such as cement and iron fulvic acid are used alone, the nutrients may become too difficult to dissolve in water, and if nutrients such as sand or gravel and fulvic acid are used alone, the nutrients may quickly leak into the water. .

Cement refers to a powder that hardens by hydration or polymerization with water or liquid agents, and is a combination of at least two or more of these (including adhesives), such as asphalt, glue, resin, gypsum, and lime. including. Sand includes crushed debris with particles having a particle size of 2 millimeters to 1/16 mm (62.5 micrometers (μm)). It is composed of clastic materials (clastic deposits) such as rock fragments and mineral fragments produced during the process of weathering, erosion, and transportation of rocks, and may also contain calcareous fossil fragments such as corals and shells.

It may also include crushed rocks created by crushing rocks by artificial means. Gravel is larger than sand, and is a collection of debris up to about 5 cm in diameter, or a collection of stones mixed with sand. Similarly, it is composed of clastic materials (clastic deposits) such as rock fragments and mineral fragments produced during the process of weathering, erosion, and transportation of rocks, and may also contain calcareous fossil fragments such as corals and shells. , may also include crushed rocks created by crushing rocks by artificial means.

That is, the sand and gravel (granular stone) contained in the fertilizing body 1 may have the same components and only differ in the size of their grains. Of course, not only the size but also at least some of the components may be different. The stones, sand, and gravel contained in the fertilized body 1 preferably contain ores (nutrient sources) containing elements such as magnesium, barium, strontium, rubidium, nitrogen, phosphorus, and potassium. Alternatively, in addition to sand and gravel, nutrients such as magnesium, barium, strontium, rubidium, nitrogen, phosphorus, and potassium may be powdered and mixed into the fertilized body 1. It is better to include a plurality of types of such nutrient sources in the fertilizing body 1. In particular, it is better to include nitrogen, phosphorus, and potassium. In such a nutrient source, the presence of iron fulvic acid (in the divalent iron state) makes it easier for algae to absorb nutrients, which further affects the growth of algae.

As a result, nutrients such as iron fulvic acid (divalent iron state), ore, rock salt, etc. can be included in the fertilized body 1, and the nutrients can be dissolved in water (seawater and rivers). This can encourage the growth of algae. The hydrogen ion index (pH) of the fertilized body 1 is less than 8, and most preferably 7.7 to 7.9.

The size of the fertilizing body 1 in FIG. 1 is approximately a rectangular parallelepiped of approximately 2 cm x 2 cm x 2 cm. The shape of the fertilizing body 1 may be a substantially rectangular parallelepiped as shown in FIG. Of course, it may be an honest parallelepiped, or any shape such as a substantially polyhedron, a regular polyhedron, a substantially sphere, or a sphere. Choosing a rectangular parallelepiped or polyhedron with a large surface area allows nutrients to be leached into the sea efficiently, and by reducing the surface area like a sphere, nutrients can continue to be leached for a longer period of time.

As for size, whatever the shape, the maximum width should be 1 cm to 10 cm, preferably 1 cm to 5 cm. By making it this size (smaller than an artificial reef), it can be used in coastal sandy, muddy, rocky areas, etc., without taking up too much of the area where algae can take root (sandy, muddy, rocky areas). The fertilizing body 1 can be placed in water (spraying or the like may also be used).

In addition, since the fertilizer application body 1 is of such an easy-to-carry size, it can be easily spread over a wide area by people, so it can be used to treat algae over a wide range of areas, such as coastal sandy mud areas or rocky areas. can provide nutrients. Of course, the fertilizing body 1 may be placed in any water other than sandy mud or rocky areas, such as the sea or river. Note that sandy and muddy areas refer to areas where the ocean floor and riverbed are more sandy or muddy than other areas. A rocky area is an area where there are more rocks than other areas such as sand or mud.

Further, the fertilized body 1 in FIG. 1 weighs about 55 g and has a specific gravity of about 6. If the fertilizing body 1 is too light, it will be washed away by water and the nutrients will continue to be eluted in a place far away from the place where the nutrients are needed. On the other hand, if it is too heavy, it will be difficult to spread the fertilizer 1 over a wide area in the sea by manually spreading it. Therefore, the weight of the fertilized body 1 is in the range of 20g to 1000g, preferably 20g to 200g. In addition, since it is preferable that the fertilizing body 1 continues to elute nutrients near the growing algae, it is preferable that the specific gravity is 3 or more to avoid the fertilizing body 1 from being washed away or floating to the water surface. .

Next, fulvic acid iron (divalent iron state) contained in the fertilized body 1 will be explained. As mentioned earlier, algae are decreasing in coastal areas and rivers, and rock formations are progressing. In the past, iron fulvic acid, which is produced in forest humus planting soil, flowed in from rivers as a nutrient, but the amount has decreased in recent years. Therefore, although we would like to supply fulvic acid to seawater, ordinary divalent iron fulvic acid is easily oxidized by oxygen in the water, changes to trivalent iron fulvic acid (trivalent iron ion), and immediately turns into granular iron. This results in sedimentation, making it impossible for living organisms to ingest it.

Furthermore, divalent iron fulvic acid (bivalent iron ions) also reacts with calcium hydroxide contained in concrete, resulting in trivalent iron fulvic acid (trivalent iron ions). Therefore, it is preferable that the fertilized body 1 contains fulvic acid, which can maintain a bivalent state even in water for a longer period of time.

In order to maintain the divalent state even in water for a long period of time, iron fulvic acid (in the divalent iron state) is produced by dissolving ferrous sulfate and fulvic acid, each having a pH of 4 or less, in fresh water and mixing them together. That's good. In other words, it is best to always convert it to iron fulvic acid under acidic conditions. By using ferrous sulfate with a pH of 4 or less, iron fulvic acid is difficult to change into trivalent iron for a long period of time even if it comes into contact with water such as seawater. It is preferable to blend fulvic acid in an amount of at least 0.001 to 0.1% by weight based on ferrous sulfate. In addition, the fertilized body 1 does not need to contain the above-mentioned nutrient source, and in that case, the growth of algae can be promoted by the nutrient source in the water and the iron fulvic acid (divalent iron state) in the fertilized body 1.

Fertilizer 1 is made by mixing an appropriate amount of cement, sand, gravel, micro silica, natural ore, rock salt, and other nutrient sources with water (a substance containing moisture) such as seawater, and adding the above-mentioned iron fulvic acid to the mixture. It can be produced by mixing (in the divalent iron state). Alternatively, the fertilization body 1 can be made by mixing an appropriate amount of cement, sand, gravel, micro silica, natural ore, rock salt, other nutrient sources, etc. with water (a substance containing water) such as seawater, and applying the above-mentioned materials on the surface of the mixture. It can be produced by spraying a mixture of iron fulvic acid (in divalent iron state) and fresh water or seawater. As described above, fulvic acid iron (in the divalent iron state) can be produced by dissolving ferrous sulfate and fulvic acid, each having a pH of preferably 4 or less, in fresh water and reacting them together. By using this manufacturing method, nutrients such as iron fulvic acid (divalent iron state), ore, rock salt, etc. dissolve into water (seawater and rivers) and promote the growth of algae. can.

Next, the usage pattern of the fertilizing body 1 will be explained using FIGS. 2 and 3. FIGS. 2 and 3 are explanatory diagrams of a fertilizing body according to an embodiment of the invention, respectively. The fertilizers 1 are spread (spread) from the sea, and are scattered on the seabed or riverbed in pieces. Of course, a plurality of fertilizers 1 may be placed in a net or the like and placed in the sea or river. Spreading refers to the provision of at least one fertilizing body 1 in the sea or river, and the fertilizing bodies 1 may be arranged almost evenly on the seabed or riverbed within a certain sea area, It may be arranged to be biased toward a certain area.

There are two major types of algae that live in the sea, ranging from eelgrass-like algae 11 that grows with roots in shallow coastal sand and mud, as shown in area 10 in Figure 2(a), to area 20 in Figure 2(b). There are up to 12 types of algae (including algae other than eelgrass) that spread their roots around rocky reefs as if gripping the reefs. In the area 20, an artificial reef 100 shown in FIG. 4, which will be described later, may be installed as a reef.

Fertilizer 1 is capable of supplying nutrients such as iron fulvic acid (divalent iron state) even to algae such as eelgrass that grows with roots in coastal sandy mud in areas such as area 10. can. This is because the fertilizing body 1 is not a large structure like the artificial reef 100 but a smaller structure. Of course, nutrients can be similarly supplied to algae living around a rocky reef (including the artificial reef 100) by providing the fertilizing body 1 around the rocky reef. That is, the fertilizer 1 can supply nutrients for algae to water regardless of the location, such as the coastal sandy mud area 10 or the rocky area (artificial reef 100) area 20.

Figure 3 shows an oyster farming site. In addition to the configuration shown in FIG. 2, as shown in FIG. 3(a), one or more fertilizing bodies 1 may be placed in a net 30, and the net 30 may be suspended from a raft 13 on the sea. . In this case, the fertilizing body 1 is not provided on the seabed or riverbed as shown in FIG. 2, but is located between the water surface and the seabed or riverbed. Note that the net 40 contains cultivated oysters 14. Also, in the case of cultivating oysters 14 that cannot be placed in a net as shown in Figure 3(b), the oysters 14 are not placed in the net, but the fertilized body 1 is placed in something like a net 30, and the oysters 14 are placed in the sea. You can also hang the net from raft 13 or something like that. This makes it possible to supply nutrients such as iron fulvic acid (divalent iron), which is a nutrient for oysters as well as algae.

In addition, the method of putting the fertilized body 1 in a net 30 and suspending the net 30 containing the fertilized body 1 from the water surface direction as shown in FIG. It can also be used as a source of nutrients for seafood and algae.

FIG. 4 is a perspective view of an artificial reef according to an embodiment of the present invention. The artificial reef 100 includes a substantially spherical main body portion 101 having an internal cavity formed therein. At least one upper opening 102 penetrating to the internal cavity is formed in the upper part 101a of the main body part 101. Further, a plurality of side openings 103 are formed in the side portion 101b of the main body portion 101, which penetrate to the internal cavity.

The artificial reef 100 is installed so that the bottom portion 101c of the main body portion 101 is in contact with the seabed. The shape of the main body portion 101 may be any shape as long as it can be stably installed on the seabed, and may be an irregular shape imitating a rock.

The size of the artificial reef 100 is approximately 20 cm to 2 m in height, and may be changed as appropriate depending on the location where it is installed and the type of seaweed or fish to be grown. For example, in the artificial reef 100 with a height of 70 cm, the thickness of the main body portion 101 is 15 cm and the weight is 170 kg. Further, the upper opening 102 has a diameter of 30 cm, and the side opening 103 has a diameter of 15 cm to 25 cm.

The upper opening 102 and the side openings 103 are preferably large enough to allow fish living in the position where the artificial reef 100 is installed to freely move between the outside and the internal cavity. Further, the weight (thickness of the main body portion 101) is preferably such that the artificial reef 100 does not move due to large waves such as a typhoon.

When nutrients are sufficiently supplied, seaweed and the like grow on the outer surface (upper part 101a, side part 101b) of the artificial reef 100. At this time, the algae that grows is not the algae that grows in sandy and muddy areas like eelgrass in FIG. 2(a), but the algae 12 that grows in rocky areas as shown in FIG. 2(b). By distributing or scattering the fertilizer 1 in the area where the artificial reef 100 is installed, nutrients are supplied to the algae and the growth of the algae can be promoted. Note that the fertilizing body 1 may be filled into a holding part formed in the main body part 101.

On the other hand, since eelgrass grows not on rocky areas or artificial reefs 100 but on sandy muddy ground, it is preferable to provide only the small fertilizer 1 instead of the artificial reef 100 by spraying it on the sandy muddy ground. Moreover, the nutrients in the fertilized body 1 are also effective for the growth of coral, and it is preferable to provide the fertilized body 1 around the coral that is desired to grow.

From the above, the fertilizer application body 1 contains at least iron fulvic acid (divalent) produced by reacting ferrous sulfate and fulvic acid, and at least one of cement, sand, and gravel, so that it can remove algae, etc. It is possible to supply effective and necessary nutrients to the water for the growth of plants.

In addition, the fertilizing body 1 contains iron fulvic acid (divalent), cement, sand, and gravel, so that it can supply effective and necessary nutrients for the growth of algae and the like to the water over a long period of time.

Further, the fertilized body 1 contains at least iron fulvic acid (divalent) produced by reacting ferrous sulfate and fulvic acid, has a maximum width of 1 to 10 cm, and weighs 20 to 20 cm. It is preferable that the weight is 1000 g and the specific gravity is 3 or more. As a result, it is possible to easily supply effective and necessary nutrients for the growth of algae etc. in a compact form.

The fertilizing body 1 can be provided not only in rocky reef areas but also on the bottom of sandy and muddy areas. This makes it possible to supply nutrients to both algae that grow on rocky reefs and algae that grow on sandy and muddy soil. Further, the fertilized body 1 may further contain nitrogen, phosphorus, and potassium. This allows more nutrients to be supplied to the algae. In addition, nitrogen, phosphorus, and potassium become nutritional sources for algae more efficiently when the fertilized body 1 contains iron fulvic acid (divalent).

This fertilizer application body 1 produces a mixture of at least one of cement, sand, and gravel mixed with water, and contains ferrous fulvic acid (divalent) produced by reacting at least ferrous sulfate with fulvic acid. may be produced by mixing with a mixture. As a result, it is possible to produce a fertilized body 1 containing iron fulvic acid that can maintain a bivalent state even in water for a longer period of time.

To provide a fertilizing body which has a small structure and can supply algae nutrients to the sea regardless of the location such as coastal sandy mud land or rocky areas, and a method for producing the fertilizing body.
