2. Description of the Related Art In order to purify seawater or freshwater so that fish can inhabit it, it is considered desirable to grow plants in the water. When greening underwater, a method is generally used in which a person dives underwater and plant plants by hand.

[0003]

However, there is a problem that the plants planted underwater in this manner are easily peeled off the underwater ground by a current such as a tide.

The present invention has been made to solve such a problem and to provide a method for surely fixing plants in water.

[0005]

In order to solve the above-mentioned problems, the present invention provides the following underwater greening method.

(1) An underwater revegetation method characterized in that a plant seedling is held on a holder, and the holder is submerged in water with the holder fixed to a weight.

(2) An underwater greening method characterized in that plant seedlings are held in a holding body made of plant fiber, and the holding body is submerged in water while being housed in a net together with concrete pieces or stones. (Claim 2).

(3) The plant fiber is a loofah or palm fiber (claim 3).

(4) A plurality of tubular bodies having upper and lower ends opened are disposed in a concrete frame having upper and lower ends opened. Plant seeds and seedlings are stored in each cylindrical body together with soil. Underwater is characterized by covering with a paper cover to prevent the outflow of soil in each cylindrical body for the time being, and submerging the cylindrical body in the water while being tied to the concrete frame from above the paper cover. Greening method (Claim 4).

(5) A piece of charcoal is stored in the tubular body.

Seedlings in the present specification, including the claims, refer to all or a part of a plant and used for propagation, and include seeds, spores, stems, seedlings, seedlings, scions, Rootstock and inoculum shall be included. The underwater greening method according to the present invention also includes the case where seeds and seedlings grow in water and the plants grow on the water surface.

[0012]

According to the first aspect of the present invention, since the holding body for holding the seedlings of the plant is submerged in the water while being fixed to the weight, the holding body does not flow away or float later. The seeds and seedlings held by the holder grow in water and purify the water. In the vicinity of the grown plants, small animals and fish will eventually inhabit.

The underwater greening method according to the second aspect of the present invention is such that the holding body is immersed in water in a state of being stored in a net together with a concrete piece or stone as a weight, so that the holding body does not flow away or float up later. Since the support is made of plant fiber, it is eventually decomposed in water. However, by the time the plant fibers forming the holding body are decomposed in water, the seedlings of the plant grow in the water and take root on the underwater ground. Survive on the ground. In other respects, the underwater greening method of claim 2 has the same operation as the underwater greening method of claim 1.

The underwater revegetation method according to the third aspect of the present invention is that the support made of luffa or coconut fiber preferably retains seedlings of plants and is preferably decomposed without contaminating water.
In other respects, the underwater greening method of claim 3 has the same effect as the underwater greening method of claim 1.

The underwater greening method according to claim 4 The concrete frame becomes a weight. The paper cover over the concrete frame prevents the outflow of soil in each tubular body for the time being, but will soon dissolve in water. The seedlings of the plants stored together with the soil in the cylindrical body eventually grow and extend upward. In addition, the roots of the plants eventually extend below the tubular body and reach the underwater ground.
In other respects, the underwater greening method of claim 4 performs the same operation as the underwater greening method of claim 1.

The underwater greening method according to claim 5 The charcoal pieces stored in the cylindrical body contain bubbles inside. These bubbles help the plants grow. In other respects, the underwater greening method of claim 5 performs the same operation as the underwater greening method of claim 1.

[0017]

Next, embodiments of the present invention will be described with reference to the accompanying drawings. The underwater greening method according to the present invention comprises:
Plant and seedlings of a plant are held on a holder, and the holder is submerged in water with the holder fixed to a weight. One example is shown in FIG. 1 and FIG.

That is, in the cases shown in FIGS. 1 and 2,
The seedling 1 of the plant is held on a holding body 3 made of plant fiber,
The holder 3 is immersed in water while being stored in a net 7 together with the concrete pieces or stones 5.

The plant fibers constituting the support 3 are preferably loofah or coconut fibers. The net 7 is a wire net as an example. The one shown at 9 is a growing plant,
Reference numeral 11 is the root.

Next, the cases shown in FIGS. 3 and 4 will be described. Reference numeral 13 denotes a concrete frame having upper and lower ends opened. A plurality of tubular bodies 15 having upper and lower ends opened in the concrete frame 13 are arranged. The cylindrical body 15 is, for example, a cylindrical body. The seeds 1 of the plant are stored together with the soil 17 in each cylindrical body 15. A paper cover 19 is placed on the concrete frame 13 to prevent the outflow of the soil 17 in each tubular body 15 for the time being. The tubular body 15 is immersed in the water while being bound to the concrete frame 13 by binding means 21 such as a rope or a string from above the paper cover 19. In this case, plants having direct roots are preferably used.

[0022]

According to the first aspect of the present invention, the holding body for holding the seeds of the plant is submerged in the water while being fixed to the weight, so that it will not be washed away or lifted up later. The seeds and seedlings held by the holder grow in water and purify the water. Sludge-like water bottoms are also preferably purified. In the vicinity of the grown plants, small animals and fish will eventually inhabit. Also, when the plants take root on the underwater ground, sand erosion is prevented.

[Invention of Claim 2] Since the holding body is immersed in water while being stored in a net together with a concrete piece or a stone serving as a weight, the holding body will not be washed away or lifted up later. Since the support is made of plant fiber, it is eventually decomposed in water. However, by the time the plant fibers forming the holding body are decomposed in water, the seedlings of the plant grow in the water and take root on the underwater ground. Survive on the ground. In other respects, the underwater greening method of claim 2 exhibits the same effect as the underwater greening method of claim 1.

[Invention of claim 3] The support made of loofah or coconut fiber preferably retains plant seeds and seeds, and is preferably decomposed without polluting water. In other respects, the underwater greening method of claim 3 has the same effect as the underwater greening method of claim 1.
