Description

  The present invention relates to a hydroponics panel that is floated in a row on a culture solution in a culture solution tank.

Hydroponic cultivation is carried out in which a plant for hydroponics is floated on a culture solution in a culture solution tank to grow the plant.
Conventionally, a foamed polystyrene board in which a plurality of planting holes are formed is used as the hydroponics panel.

However, since a polystyrene foam board has the unevenness | corrugation produced at the time of shaping | molding on the surface, when it uses as a panel for hydroponics, dirt tends to adhere to the surface. Moreover, it takes time to clean the dirt adhering to the surface, and the dirt tends to remain on the surface, which causes problems in cleaning work and hygiene.
Furthermore, because the surface of the polystyrene foam deteriorates due to ultraviolet rays or the like to produce white powder, when used as a hydroponics panel, it is good at first, but after a while the foam polystyrene board is used for shipping and cleaning of plants. When it comes into contact with the surface, white powder adheres to workers and plants, and from the point of view of hygiene, it was difficult to use the expanded polystyrene plate for a long time.

  In addition, the conventional hydroponics panel made of a styrofoam plate is used in the culture solution tank when the hydroponics panel is taken out from the culture solution in the culture solution tank or when the hydroponics panel is arranged on the culture solution. The width | variety of the panel for hydroponics is made smaller than the distance between the side walls of the width direction both sides of a culture solution tank. Therefore, there is a problem that a gap is formed between the side walls on both sides in the width direction of the panel for hydroponics and the culture solution tank, and algae is easily generated in the culture solution due to light incident on the culture solution from the gap, which requires troublesome cleaning. . In addition, gaps were easily generated between the panels for hydroponics arranged in a line, and algae were easily generated in the culture solution by light incident on the culture solution from the gaps.

  Furthermore, when the hydroponics panel made of a conventional expanded polystyrene plate is moved in the culture solution tank in a state of being floated on the culture solution, it is necessary to move it by pulling in turn from the hydroponics panel at one end, It took time to move. Also, if you try to push a plurality of hydroponics panels together by applying force to one end of the hydroponics panel, the end of the hydroponics panel gets on the way or sinks down and stops moving. On the contrary, it may take time and effort.
