Bed for hydroponic cultivation {BED FOR HYDROPONICS}

The present invention relates to a bed for hydroponic cultivation, and more specifically, the height of the side wall can be easily and freely changed according to the plant cultivation method, and the spray angle of the spray nozzle can be arbitrarily adjusted. This is about hydroponic cultivation beds.

Hydroponics is a method of cultivating terrestrial plants using culture media or clean water without soil in a facility that meets certain standards.

These types of hydroponics can be broadly divided into culture media, spray culture, deep flow technique, thin film technique, and Ebb and Flow system.

Among these, the atomization method is a method of cultivating plants by spraying culture medium onto the roots at regular intervals while the plant's roots are suspended in the air above the bed, while the liquid hydroponics (DFT) method fills the bed with culture medium and places a pot on top of it. ) is covered and the roots of the plant are immersed in a culture solution (nutrient solution) and the above-ground part is grown on a bed. The thin film hydroponic (NFT) method is a method of growing by continuously flowing the culture solution (nutrient solution) into the bed to the roots of the plant little by little using a pipe.

However, the height of the side walls of the beds used in hydroponic cultivation vary depending on the plant cultivation method, so there are limitations in their use as they cannot be used universally.

In particular, in the case of beds used in the spray method, it is difficult to control the spray direction and range of the spray nozzle that sprays the culture solution, so the culture solution is not sprayed properly in certain areas such as the edges of the bed, preventing plants from growing normally and uniformly. There is a problem that I cannot do.

The background or prior art described above is information possessed by the present inventor or acquired in the process of deriving the present invention, and is only intended to help understand the technical significance of the present invention, and is information to which this invention belongs before filing the application for the present invention. It should be noted that this does not mean that it is a widely known technology in the field.
