Abstract

PROBLEM TO BE SOLVED: To solve a problem that a shore denudation symptom for annihilating the seaweed bed of a shore sea bottom due to the emergence of calcareous algae reaches the beaches of the whole country and further a problem that when the calcareous algae once emerges, the surfaces of rocky shores, shore reefs and the like are covered with hard limestone layers and thereby make it impossible to root and vegetate the spores of sea weeds such as sea tangles or Sargasso, while the decrease in the catches of inshore fishery is caused by the decrease of fish-spawning seaweed beds, in recent years. SOLUTION: Nutritive fertilizers, such as fulvic acid iron salt, required for the growth of sea tangles, seaweeds, and the like, are absorbed and held in the seaweeds- vegetating blocks, and then left in a culture pond or in a culture tank to root and vegetate the seaweeds. Or, the seaweeds-vegetating blocks absorbing and holding the nutritive fertilizers are put in a basket, a net, or the like and then left on a shore denudation-free shore to naturally root and vegetate the seaweeds. After the growth of the seaweeds is confirmed, the blocks are thrown in and set to a denuded fishing bank, a denuded seaweed bed, or the like. The object of the seaweeds-vegetating blocks is the prevention of the denudation symptoms caused by the calcareous algae to restore the seaweeds and the like of the seaweed beds.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for recovering and planting seaweed beds where useful seaweeds such as kelp have disappeared due to the shore-burning phenomenon of rocky reefs nationwide.

[0002]

2. Description of the Related Art An erosion phenomenon caused by lime algae that occurs in rocky reefs facing the open ocean and rocky shores of seashore has occurred, and useful seaweeds have been killed and seafood has become a white, dead shallow sea.

[0003] In recent years, it is said that one part of the decrease in catches of coastal fisheries is that fish and the like lose their spawning sites due to the decrease in seaweeds and seaweed beds due to the shore burning phenomenon.

It is said that iron fulvic acid is deficient in what is considered to be one of the causes of rock burning. Fulvic acid is a material that combines the fulvic acid created when bacteria living in forest soil decompose leaves and the iron content originally contained in the soil, nitrogen and phosphorus when reaching the sea, It is indispensable for seaweeds that are absorbed by seaweed along with nutrients called inorganic substances such as potassium. Since the devastation of the mountains has been pointed out, hardwoods have been planted on the devastated mountains.

[0005] Since rocks on a rocky beach are covered with a hard film of calcium lime, calcium spores, spores of seaweeds cannot be settled, and stones are newly thrown to try and settle vegetation of seaweeds. (Example JP-A 2001-178303 JP-A 2000-
262180 JP-A-11-262180)

[0003]

Since the surface of a conventional rocky reef such as lime algae is covered with a hard lime layer, spores of seaweed could not be attached.

[0004] It has been found that iron fulvicate, which is an iron component necessary for the growth of seaweeds, is extremely small in reefs covered with lime algae. Iron fulvicate inhibits the reproduction of lime algae. I have also come to understand that there is work.

[0005]

Means for Solving the Problems The vegetation block for seagrass of the present invention is a microporous mineral that adsorbs nutrients including iron,
Blocks made of zeolite, unglazed pottery, bricks, sludge, etc., which have been hardened,
Soak iron in a bath containing nutrients and iron to absorb fulvic acid, nitrogen, phosphorus, potassium, etc. In order to achieve the above object, the vegetation block of the seaweed of the present invention has a large number of fine pores, and the fulvic acid iron, nitrogen, phosphorus, potassium, etc. necessary for seagrass to grow are adsorbed in these fine pores. , Seagrass is alive and vegetation is easy.

For the vegetation block of seagrass which requires the above-mentioned fine pores, sepiolite, which is a mineral zeolite capable of adsorbing iron fulvicate, nitrogen, phosphorus and potassium, may be used.

As the vegetation block of seagrass which requires the above-mentioned fine pores, a block having fine pores obtained by baking sludge or the like may be used.

The vegetation block of seagrass requiring fine pores described above may be a brick having fine pores for adsorbing iron fulvicate and nutrients.

As the vegetation block of seaweeds requiring the fine pores described above, unglazed pottery having fine pores for adsorbing iron fulvicate, nutrients and the like may be used.

[0010]

[Means for Solving the Problems] In order to achieve the above object,
Since the seaweed vegetation block of the present invention adsorbs the iron fulvic acid and nutrients necessary for the seaweed to grow, spores of seaweed are alive and vegetation can be facilitated.

The seaweed vegetation block described above is immersed in a bath of an aqueous solution in which iron fulvicate, nutrients and the like are dissolved, and the block adsorbing iron fulvicate, nutrients and the like is pulled out from the bath, and a water tank containing spores of seaweed Dip in and vegetate seaweed on the block.

After confirming the growth of seagrass on the vegetation block of seagrass, the seagrass is dumped on a rocky reef and the like.

The vegetation block of seaweeds is put in a cage, a net or the like in an shore that has not been shore-burned, and the seaweeds are naturally grown on the blocks. After confirming the growth status of the seaweeds vegetated on the block, the seaweeds are transported to the shore, where shore burning is occurring, and the vegetation blocks are discarded to plant the seaweeds.

It is also possible that only the fulvic acid iron is adsorbed on the vegetation block of seaweeds, and the vegetation blocks are dumped on rocky reefs and the like for natural survival and vegetation of seaweeds.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. The vegetation block of seaweeds is soaked in a solution in which iron fulvicate and nutrients are dissolved, and the fulvic acid and nutrients are adsorbed and then taken out of the bath, and the block is soaked in a solution in which spores and the like of seaweeds are dissolved.

FIG. 1, a vegetation block (2) of seaweeds is immersed in a bath (1) of an aqueous solution in which nutrients necessary for the growth of seaweeds are dissolved, and after adsorbing the nutrients to the blocks, the block (2) is placed in a bath (1). ), And soak the block (2) in the water tank (3) in which the spores of seaweed and the like are dissolved, and let the seaweed grow.

[0017]

EXAMPLE The vegetation block of seaweeds of the present invention has a size that can be carried by a person and a weight that can be dumped by a person when the adsorbent mineral is a zeolite block. Moreover, this does not apply when used for a reef in a rough sea facing the open ocean.

[0018]

INDUSTRIAL APPLICABILITY As described above, according to the present invention, seagrass is vegetated in a block immersed in an aquarium, and the survival, vegetation and growth of seaweed can be visually confirmed. Can be dumped and planted on burnt reefs.

[0019]

[Application example brought about by the effects of the present invention] Fig. 2 The vegetation block of seaweeds having fine pores according to the present invention is used as a vessel in which unglazed pottery, bricks, powdered zeolite, sepiolite, sludge and the like are baked and solidified. The concentrated aqueous solution of iron fulvic acid is put into the container, the lid is cemented, and it is dumped on rocky reefs that are burned by the sea, and the fulvic acid iron leaching from the block for a long period of time inhibits the growth of lime algae. Seagrass can naturally grow on the pottery blocks.
