Abstract

PURPOSE:To improve planting and growin efficiency and promote cleaning of water by curling up synthetic fiber to orient it voluminously, fixing a mat which has a large porosity and is prepared by fixing the crossing points and the peripheral parts with a binding agent, and planting water plants by inserting the stalks of the plants in the mat. CONSTITUTION:A mat 3 is fixed by stakes 4 in underwater ground 1 of a lake front or a river bank in which plants are about to be planted and grown and stalks of a water plant 2 such as a ditch reed, etc., are inserted in the mat 3 in a prescribed distance L and planted in the ground 1. At that time, since the mat 3 is so prepared as to have the porosity of 90% or more, the stalks can be inserted easily and the root parts of the stalks of the water plant 2 are held and fixed by plastic fiber of which crossing points are fixed by a binding agent, so that even if wave moves, the bottom sludge is prevented from being dug and the water plant 2 is surely rooted. Since the mat 3 is made of synthetic resin, it does not go rotten and the planted plant 2 is also prevented from dying.

Description

Detailed Description of the Invention

[0001]

The present invention relates to nitrogen (N ₂ ) in water,
The present invention relates to a method of planting an aqueous plant such as reed or watercress, which removes phosphorus (P) and the like to purify water, at a location where waves move, such as a lakeshore or a riverside.

[0002]

2. Description of the Related Art Conventionally, there is a method of planting in a place where the movement of waves is as small as possible and increasing the number of planting areas one by one, or a method of driving piles into the ground to reduce the movement of waves and planting. It was done.

[0003]

However, in the above-mentioned conventional methods, the inserted aqueous plants often do not root out because the bottom mud is excavated by the waves due to the excavation of the bottom mud, and it is difficult to purify water. Had a point.

An object of the present invention is to solve the above problems, to improve rooting of an aqueous plant to improve planting efficiency, and to promote purification of water.

[0005]

In order to achieve the above object, the present invention is a method for planting an aqueous plant on an underwater ground where waves such as a lakeshore and a river are moving, in which a synthetic fiber is crimped to make it bulky. It is characterized in that the mat having a large porosity is firmly fixed to the underwater ground by firmly orienting and firmly fixing the intersections and the periphery thereof with a binder, and the stem of an aqueous plant is inserted and planted in the mat.

[0006]

Since the stems of the aqueous plants are inserted into the mat fixed to the aquatic ground, the inserted aqueous plants are fixed and root without being exposed to the waves, so that the planting efficiency can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes an underwater ground such as a lakeshore or a riverside, and the ground 1 has a gentle slope.

Reference numeral 2 denotes an aqueous plant to be planted. The aqueous plant 2 is composed of a plant such as reed or watercress that removes nitrogen (N ₂ ) or phosphorus (P) from the water and is exposed to the surface of the water. It has a proper stem length.

Reference numeral 3 indicates a mat, and the mat 3 is a synthetic fiber, particularly a plastic fiber such as vinylidene chloride, having a fiber diameter of 0.2 mm to 1.0 mm, which is crimped to be oriented in a bulky manner and its intersection point and It is a flat plate whose periphery is firmly fixed with a binder such as rubber or synthetic resin, and is formed in various lengths, widths and thicknesses. The mat 3 has a bulk specific gravity of 0.04.
~ 0.08 g / cm ³ , fiber surface area 160-300 m ² / m ³ ,
It has a porosity of 90% or more and necessary and sufficient hardness and strength.

Reference numerals 4 to 4 denote piles for fixing the mat 3.

Next, a planting method using the mat 3 will be described.

Mats 3 are sequentially fixed by piles 4 to the underwater ground 1 to be planted on the lakeshore or riverside.

Next, the stems of the aqueous reeds 2 such as reeds are placed at predetermined intervals L
And then insert it into the mat 3 and plant it on the ground 1.

At this time, since the porosity of the mat 3 is 90% or more, the stem of the aqueous plant 2 can be easily inserted vertically, and the stem is made of plastic fiber whose intersections are fixed by a binder. Since the root part of the plant is held and fixed, even if the wave moves, the bottom mud is not excavated, and the rooting of the aqueous plant 2 is reliably performed.

Since the mat 3 is made of synthetic resin, it does not decay and the planted plant is prevented from dying.

[0017]

As described above, according to the present invention, a synthetic fiber is crimped and oriented in a bulky manner, and the intersection and the periphery thereof are firmly fixed with a binder to provide a mat having a large porosity on the underwater ground. Since the stems of the aqueous plants were fixed and fixed to the mat, the movement of the bottom mud was prevented, the aqueous plants were not excavated by the waves and discharged, and further acted as a support for the plants. By doing so, rooting is improved, planting efficiency can be improved, and water purification can be promoted.
