Abstract

PURPOSE: To obtain a raft for plant culture, effective for improving the fixing and root-taking of a plant and having excellent durability and handleability by covering an expanded polystyrene board with a nonwoven cloth, etc., boring plural holes on the expanded polystyrene board and detachably inserting planting pots into the holes. CONSTITUTION: An expanded polystyrene board 2 having plural holes 5 extending through the board from the top to the bottom is covered with a nonwoven cloth 3 and a sheet 4 of coconut fiber and a planting pot 6 having mesh bag form is detachably inserted into each hole 5 to obtain the objective plant culture raft 1. Preferably, plural plant culture rafts 1 are connected with each other by sandwiching the rafts with plural polyvinyl chloride pipes 9 from the top and bottom and floating on a water surface.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a raft for cultivating plants,
Specifically, it relates to a raft that cultivates plants using the water surface and contributes to improving water quality and beautifying the environment.

[0002]

2. Description of the Related Art In recent years, eutrophication of lakes and rivers and water pollution have been taken up as environmental problems. For this reason, various water quality improvement methods have been attempted. Among them, the hydroponics method involves floating a raft for plant cultivation on the water to absorb inorganic nutrients (chisso, phosphorus, potash, etc.) in water by plant roots. ,
It is a method of purifying water quality.

As such a raft, conventionally, a styrofoam plate which is buoyant and inexpensive is provided with a plurality of holes penetrating from the upper surface to the lower surface, and the root portion of the plant is wrapped with a sponge in the holes to directly I pushed it in and planted it, and left it floating on the surface of the water.

[0004]

However, since the Styrofoam plate has a strong image of pollution, it is not suitable for beautification of the environment when it is exposed. May become fragile quickly and may splash on water.
In addition, it takes time and effort to plant and remove plants,
Planted plants sometimes fell into the water.

Therefore, an object of the present invention is to provide a raft for plant cultivation, which is durable and suitable for beautification of the environment, is easy to plant and remove, and has good plant fixation and survival. .

[0006]

In order to achieve the above-mentioned object, the present invention provides a raft for plant cultivation using a Styrofoam plate having a plurality of holes penetrating from the upper surface to the lower surface,
The styrofoam plate is covered with a sheet of non-woven fabric and coconut fiber, and a net-bag-shaped pot for planting plants can be attached to and detached from the hole.

[0007]

[Operation] According to the above configuration, since the Styrofoam plate is covered with the nonwoven fabric and the sheet of coconut fiber, the durability is high,
In addition, it is also aesthetically pleasing. Furthermore, since the plant is put in a net bag-shaped pot and is attached / detached to / from the holes of the styrofoam plate, the plant can be easily planted and removed, and the plant can be fixed and lived well.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below based on the embodiments shown in the drawings.

The raft 1 for plant cultivation has a length of 1,000 mm,
Styrofoam plate 2 with a width of 500 mm and a thickness of 60 mm
Is covered with a light-resistant non-woven fabric 3 and a sheet 4 of coconut fiber, and a plurality of circular holes 5 (6 to 25 pieces / square meter) penetrating from the upper surface to the lower surface are evenly formed in the styrofoam plate 2. There is.

A mesh bag-shaped pot 6 for planting a plant is detachably provided in the hole 5. This pot 6 has a conical shape in this embodiment, and the root portion of the plant 7 is wrapped in a sponge 8 and inserted into the pot 6, and the pot 6 is attached to the hole 5 of the styrofoam plate 2. The pot 6 may be cylindrical.

The raft 1 for plant cultivation constructed in this way,
Plural vinyl chloride pipes 9 and 9 are sandwiched from above and below to be connected and floated on the water surface. As a result, the plant 7 grows by absorbing nutrients from the water, and particularly absorbs inorganic nutrients (chisso, phosphorus, potash, etc.) in the water, which contributes to purification of water quality and beautification of the environment.

Further, the raft 1 for plant cultivation has high durability because it protects the Styrofoam plate 2 with the light-resistant non-woven fabric 3 and the sheet 4 of coconut fiber, and prevents deterioration due to ultraviolet rays and runoff due to damage, and also the Styrofoam plate. Since 2 is not directly visible, it is also aesthetically pleasing.

Furthermore, since the plant 7 is placed in the net bag-shaped pot 6 and attached to the hole 5 of the styrofoam plate 2, it is easy to plant and remove the plant 7, and the root portion of the plant 7 is wrapped with the sponge 8. Therefore, even plants 7 of different sizes can be freely fixed in the pot 6 without damaging them, and appropriate water and humidity can be maintained, so that the plants 7 can be fixed and lived well. By setting a slow-release fertilizer between the root portion of the plant 7 and the sponge 8, the initial growth of the plant 7 can be promoted.

[0014]

As described above, the raft for plant cultivation of the present invention covers the Styrofoam plate with a sheet of non-woven fabric and coconut fiber, and pierces the Styrofoam plate with a plurality of holes penetrating from the upper surface to the lower surface, Since a net bag-shaped pot for planting plants can be attached to and detached from this hole, it has high durability and prevents spillage due to deterioration and damage due to ultraviolet rays, and since the Styrofoam plate is not directly visible, it is also aesthetically pleasing. Will be things.

Further, since the plant is put in a net bag-shaped pot and attached to the holes of the styrofoam plate, the plant can be easily planted and removed, and the plant can be fixed and lived well.
