Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention 1: Production of Moriculture] The present invention relates to an apparatus for hydroponic cultivation on the surface of water such as a lake or marsh.

Blood sand cultivation, gravel cultivation, and hydroponic cultivation are cultivation methods that do not use soil.

This is a cultivation method in which a mat or the like is filled and used as a bed for growing plants. This cultivation method uses a variety of systematized manufacturing techniques, such as creating a greenhouse above the equipment, circulating an aqueous solution, bubbling, and devising fillings and beds. However, this method has the disadvantage that it can only be used on the ground, which limits the amount of land available for agricultural production.

The present invention has been made in order to eliminate the drawbacks mentioned above.
The purpose of the present invention is to provide a hydroponic cultivation device capable of creating new farmland by combining a vast area of various water surfaces, which have not been used at all as agricultural production land, with hydroponic methods.

[Structure 1 of the Invention: 11. The present invention departs from the conventional idea of a cultivation method fixed on the ground, and instead uses water 1f in reservoirs, creeks, gums, lakes, etc.
By floating a bed for plant cultivation on the ii and connecting the water in the lower layer and the vent with capillary water, parasitic plants,
This is the cultivation of wet plants etc. using industrial methods.

The industrial method is the production of agricultural products of constant quality on water using simplified operations using cheap and standardized beds.

That is, the present invention provides a cylindrical or cubic object having a void inside, by providing holes in the two sides or the bottom part of the object, and connecting and fixing a plurality of the objects with the surface with the hole facing downward. Remove the upper cover of at least one or more cylindrical or cubic objects constituting the water surface floating object, and place a hydroponic cultivation bed on a part of the water surface floating object. By filling the cylindrical or cuboidal object with the lid covered and the top cover removed with gravel, bed, etc., which have a weight of 1g that can cause capillary rise, moisture can be added to the hydroponic cultivation vent.
An apparatus for hydroponic cultivation on the water surface, which is configured to supply nutrients.

Next, embodiments of the present invention will be described with reference to the drawings.

In the embodiment, a hollow wire is used as a cylindrical or cubic object having a void inside.3 Since the hollow wire already has a hole, there is no need for any processing, and the height is also uniform. In addition, capillaries within the skyline - capillaries with the ability to rise (e.g. scoria from Mt. Fuji), peat lumps,
When a synthetic resin molded article having communicating voids is inserted to cultivate plants, the height of the empty wire corresponds to a height appropriate for 1-2 rises of capillary water. Taking these points into consideration, empty lines were used. Figure 1 is a plan view of the case where empty lines of the same shape and height are connected, and Figure 2 is a plan view of the case where empty lines of the same shape and height are connected. It is an A sectional view. 1 is an empty wire, and it is connected and fixed with wire 2 so that the hole 1' is at the bottom to form a floating object on the water surface.The connecting buttons are two-tiered, but they can be changed as needed depending on the strength required. In addition, if the empty wire 1 is configured to connect and fix without using wire, rope or tape may be sufficient. Sora Nii 4 no 1
- When the lid is removed, a part of the empty wire 1 and the hole in the bottom of the empty wire 61S are configured so as to communicate with each other.

Empty A4 corresponds to the planting needle of irrigation cultivation, and several other empty lines 1
3. The buoyant force of the water surface floating object 3 is 25 (l), which doubles as a float f-3.
If it is a liter container, there will be about 5 pieces (10 pieces per set).

When the object 3 floating on the water surface is floated on the water surface, it becomes as shown in Fig. 2. 5 is the water surface, and the empty line 1 is caused by the weight of the object 3 floating on the water surface.
Water infiltrates into the prison and forms a water surface 6 inside the prison. Water surface゛)71
Object: The empty line 4 in the center of (-h) causes water to infiltrate to the same height as the water surface 5 due to the force of the spring being removed.

FIG. 3 is a sectional view of plants grown in the apparatus of the present invention. The water surface 5 is the water surface of a pond, a creek reservoir, a gum, or a lake. A layer 7 is laid at the bottom of the empty wire 4 in the center of the floating object 3, and a part of it is filled with capillary gravel.
Cultivate 0. IJ is placed on one side of the object 2 3 floating on the water surface, and the synthetic resin vent 5 is covered so as to come into contact with the capillary gravel. The shade 7 is for preventing gravel 8 from falling outside the air line. Alternatively, the Japanese pine gravel 8 may be omitted, and a synthetic resin vent that allows the capillary water to rise by 1 m may be configured to be brought into direct contact with the water surface. Depending on the plants to be cultivated, a mat may be placed in place of the bed made of synthetic wood 1j11.3 Also, the number of empty winds may be 7 or 30, and the arrangement may be made with holes as appropriate. Furthermore, instead of a bed, 1
- When using soil, build an enclosure wall around the top of the water surface floating object 1 object 3.

- When growing plants in a synthetic resin bed [- in the configuration described in I-, water and nutrients necessary for the plants are guided from the water surface 5 to the bed 9 by capillary hydrophilicity 4, and if nutrients are insufficient, the bed 9 You can add granular fertilizer to it. Furthermore, since the present invention utilizes empty wires as waste, it is possible to effectively utilize waste and reduce costs.

FIG. 4 is a plan view of a case in which a large number of devices of the present invention are arranged in a pier-like manner near the inflow of polluted lakes and marshes. 11

Reference numeral 14 denotes a work passage built over 13. Depending on the plants to be cultivated, a tunnel-shaped greenhouse may be provided in the hydroponic cultivation facility-1. In addition, aquatic plants such as water hyacinth are
Harvesting, processing, etc. would be easy if the cultivation was carried out in a water area divided by 71 passages. Vast areas of various types of water, which had previously been completely unused for agricultural production, can now be created as new farmland.

In addition, the tourism value of shallow lakes and marshes is decreasing due to eutrophication, which is having a negative impact on their use as bathing areas and on fishing. However, by directly removing nitrogen and phosphoric acid from lakes and marshes through hydroponics, It has the effect of purifying.

Application examples of the device 6 of the present invention will be listed.
