Description

  The present invention relates to a hydroponic cultivation apparatus provided with a device for immersing a plant in a culture solution in order to control pests attached to the plant to be cultivated.

  In the hydroponic culture in which the root is immersed in the culture solution while supporting the fixed planting panel (hereinafter referred to as the plant planting panel) on which the plant is planted on the liquid level in the cultivation tank containing the culture solution, First, as a method of exterminating pests attached to a plant, a method of immersing a plant planting panel in a culture solution of a predetermined concentration for a predetermined period of time during hydroponics and suffocating the pest, and planting the plant Proposes a method of removing the pests from the plant by repeatedly immersing the panel in the culture solution for a short time, and then recovering and disposing of the pests that sink into the culture solution or float on the liquid surface, along with hydroponics We have proposed many hydroponic cultivation devices with pest control plant dipping devices that can immerse the plant planting panel in the culture solution as needed and return to the original hydroponic culture after treatment.

  As an example, a plant planting panel having a vacant space inside is floated on the surface of the culture solution, and a liquid is poured into the vacant chamber to sink the plant planting panel into the culture solution. There are some which float the plant planting panel to the liquid level by pouring.

  Moreover, as what is suitable for large-scale hydroponics using a large cultivation tank of width 1.5-2.0m and length 15-20m, for example, in the cultivation tank, the endless chain extended in a longitudinal direction is the upper part. A straight zone is placed on the surface of the culture solution and the lower straight zone is movably disposed in the culture solution, and a plurality of plant planting panels are connected to the endless chain. An endless chain running type that moves the plant to a state where the plant is exposed in a normal position on the culture solution and a state where the plant is immersed in a standing posture in the culture solution, or a plant planting panel floated on the culture solution surface. The plant is inverted downward while being pulled up, the plant planting panel is lowered to the liquid level in that state, the plant is immersed in the liquid in an upright posture, and then the plant is pulled up while the plant planting panel is pulled up on the liquid level. Flip it up and plant planting Those of the inverting back to normal hydroponics is lowered Le on the liquid surface has been proposed.

  However, the former has the disadvantage that it takes time and effort to produce a fixed-planting panel with vacancies, and the latter two are not only expensive but also expensive, and the cultivation tank is deep. Therefore, there is a difficulty in using a large amount of expensive culture solution.

Furthermore, when any of the above conventional devices uses a large cultivation tank, the culture solution is discharged from one end of the tank in the longitudinal direction and sent to the filter, and the filtrate is pumped from the other end in the longitudinal direction of the cultivation tank. Although it has a piping for filtration circulation that returns to the inside of the tank, there is a disadvantage that a long piping is required and the equipment cost is increased.
