Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a panel for nutrient solution culture, a nutrient solution system and a nutrient solution method which are floated on a culture solution.

Conventionally, a nutrient solution cultivation is performed in which a plant is cultivated by floating a nutrient solution culture panel on which a plant is planted in a culture solution.
As a panel for hydroponic cultivation, the expanded polystyrene board in which the planting hole was formed in multiple numbers is common.

In addition, in the cultivation of leafy vegetables such as Komatsuna, spinach, and sea urchin, the air of the stock origin may stagnate and become a hotbed of diseases and pests.
In open-field cultivation, as a measure against moisture of the plant origin of leafy vegetables, a duct of vinyl hose with small holes is placed along the weirs and air is blown out from the holes, but from the soil surface The dehumidifying effect is low due to the supply of moisture.
In nutrient solution cultivation using a panel for nutrient solution cultivation, the dehumidifying effect can be expected even by the duct, but its equalization is difficult.

  In addition, in order to improve the growth of plants, it is preferable to set the atmosphere temperature suitable for plant cultivation, but it is expensive to heat-control the entire building in which the hydroponic cultivation apparatus is installed. There's a problem.
