2. Description of the Related Art In coastal waters, there are seabeds such as bedrock in which useful seaweeds grow, and these seabeds are places for feeding and spawning grounds and important roles for marine life. Useful seaweeds are edible seaweeds such as kelp and wakame, seaweeds such as sea bream and sardine that feed on turban shells and abalone, and the zoospores (spores) of these seaweeds floating in the sea attach to the bedrock of the seabed. And grow. The roots of these seaweeds are called roots, which have the sole function of fixing the body, and they absorb nutrients from the roots and do so on the entire body surface. These seaweeds release spores from September to October, attach to rocks, germinate, and grow during the winter.

In recent years, useful seaweeds such as kelp, seaweed, sea bream, and swordfish that have been flourishing until now have died without growing.
There is a phenomenon commonly referred to as Isoyaki where the rock surface is exposed or covered with lime algae. It is known that shore burning affects not only the seaweed aquaculture industry but also the ecosystem of fish inhabited by seaweed, which is a serious problem for coastal fisheries. In order to improve shore burning, stones, concrete blocks, steel aggregates, etc. are put in the coastal waters where shore burning is observed, and the surface of rocks under the sea where lime alga adheres is cleaned.
However, although it has been confirmed that useful seaweeds grow at first on the surface of the input material and on the cleaned surface, after all, when the lime algae start to grow, the useful seaweeds will not take root in a few years. It has not been improved yet.

Humic acid not only serves as a nutrient for useful seaweeds such as kelp and seaweed and promotes their growth, but also contains a large amount of silicon and promotes the growth of diatoms. Useful seaweeds ingest iron from seawater, which is essential for chlorophyll synthesis. It is known that divalent and trivalent iron ions are very difficult to be absorbed, but as an iron chelate of humic acid, it has a very high absorption effect. Moreover, since humic acid itself contains nitrogen, it is suitable as a nutrient for useful seaweeds.

Diatoms are phytoplankton, play a part in the normal food chain, and have a function of suppressing the growth of lime algae that inhibit the rooting of useful seaweeds, together with the growth of useful seaweeds. Lime algae is also called coral algae,
It is a type of alga with a calcareous shell. In the sea area where the sea shore burned (iso ware sea area), useful seaweeds disappeared, and lime algae grew on the surface of the rocks on the seabed where they were originally rooted, and it became pure white. It is known that lime algae grow so as to cover the surface of rocks on the seabed closely, and that the substances secreted by lime algae inhibit the rooting of useful seaweeds on the rocks.

Humic acid is a substance that inhibits the crystallization of the calcium component necessary for the growth of lime algae, and the decrease of humic acid causes the growth of lime algae. Humic acid is
In the natural world, it is a black-brown organic substance that is mainly present in soil and is particularly abundant in soils such as deciduous humus and rot.
Soil containing humic acid flowed into the river and was supplied to the coastal sea area as useful nutrients for useful seaweeds. However, the number of broad-leaved trees has gradually decreased due to recent deforestation and coniferous tree planting, and the amount of humic acid flowing into coastal waters via rivers has decreased. In order to eliminate this, some fishing villages are actively planting broadleaf trees in the upstream areas of the rivers that flow into the fishing grounds, but it is not possible to supply sufficient humic acid to the seashore in the shore. However, there is no useful means yet. Therefore, the present inventors have found that by mixing and solidifying the humic acid-based substance and gypsum, it is possible to effectively supply the humic acid-based substance to the seashore of the sea burning.

The method for producing the humic acid-based material supplier is not particularly limited as long as the humic acid-based material and gypsum can be mixed and solidified and molded. For example, lignite and / or brown coal is decomposed with nitric acid or an acid such as nitric acid and sulfuric acid, and neutralized with a calcium compound or a magnesium compound to obtain a humic acid-based substance. The obtained humic acid-based substance and gypsum are sufficiently mixed, for example, in a weight ratio of 1: 1 to form a mixture (solidified material). This mixture is filled in a predetermined mold and solidified to obtain a molded body. The solidification means is not particularly limited, and if left as it is, it solidifies to obtain a humic acid supplier of any shape.

The shape of the humic acid supply body is not particularly limited, and examples thereof include a columnar body, a prismatic body, a rectangular parallelepiped, a cone, a sphere, and a tetrapot body as shown in FIG.
The size and shape are determined according to the conditions such as the sea area where it is installed. That is, when the humic acid supplier 1 is installed (buried) in seawater or the like, gypsum gradually dissolves in seawater from the surface of the humic acid supplier 1. This is because the calcium sulfate concentration in seawater is a little over 60% of the saturated amount. With the dissolution of gypsum, humic acid-based substances gradually elute into seawater,
Humic acid-based materials are supplied. Therefore, since the humic acid-based substance is substantially proportional to the elution rate of gypsum, the humic acid-based substance is formed into a desired size and shape according to the conditions such as the sea area where it is installed, and the number (input amount) is determined. For example, if the size of the humic acid supplier 1 is reduced to increase the specific surface area, the elution amount naturally increases, but it is not suitable for long-term installation. Of course, the elution rate (dissolution rate) varies greatly depending on the sea conditions such as seawater temperature, tidal current, and salt concentration in seawater. Therefore, it is important to determine the size and installation amount of the humic acid supplier 1 to determine the sea conditions such as the seashore of the sea. Is.

As described above, the dissolution rate of the humic acid-based substance can be adjusted by changing the specific surface area by changing the size of the feeder alone. However, when the humic acid feeder is manufactured, casein (milk) is used as a binder. It can also be adjusted by adding a protein such as casein contained in the above. In other words, in the production stage of the humic acid supplier, casein was used as a binder and the weight ratio to the solidified material before solidification was 2%.
By adding less than or equal to wt% (0 to 2 wt%), casein can enter between the calcium sulfate crystals after solidification, the specific surface area at the micro level can be reduced, and the dissolution of the humic acid supplier can be suppressed. . Therefore, if it is desired to suppress the dissolution rate of the humic acid-based substance, it is possible to add a predetermined amount of casein.
