栽培装置。[Scope of Claim for Utility Model Registration] (1) Pumping up nutrient solution from a water storage tank into a cultivation tank for plant cultivation through a water pump, and then discharging the nutrient solution from an overflow drain hole or drain provided in the cultivation tank. A hydroponic cultivation device in which a nutrient solution is circulated between a cultivation tank and a water storage tank by draining water to grow plants in the cultivation tank, and the bottom of the cultivation tank or a side surface near the bottom is is formed with a second drainage hole that is set so that the amount of cultivated water is less than the amount of water pumped by the pump, and the pump is controlled by an intermittent timer.
A hydroponic cultivation device characterized by being set to drain all of the nutrient solution in the cultivation tank from a second drainage hole when the water pump is turned off by repeating N/OFF. (2) The cultivation tank is provided with a drainage pipe that projects upward from the bottom surface and forms a drainage hole for the internal nutrient solution, and a second drainage hole is formed on the proximal side of the drainage pipe. The hydroponic cultivation apparatus according to claim 1, characterized in that: (3) The cultivation tank and water tank can be connected to each other by pumping up nutrient solution from the water storage tank to the cultivation tank for plant cultivation, and draining the nutrient solution through a siphon pipe set in the cultivation tank. A hydroponic cultivation device that grows plants in a cultivation tank by circulating a nutrient solution between the siphon pipes, and the diameter of the siphon pipe is such that the amount of drainage is larger than the amount of nutrient solution supplied from the pump. A hydroponic cultivation device characterized by being set as follows. (4) By pumping up the nutrient solution from the water storage tank into the cultivation tank using a water pump, and draining the nutrient solution from the overflow drainage hole or drainage ditch provided in the cultivation tank, the cultivation tank can be used as a cultivation tank. This is a hydroponic cultivation device that circulates nutrient solution between a water storage tank and grows plants in the cultivation tank, and the water pump is turned on and off by controlling an intermittent timer.
When FF is repeated and the water pump is OFF,
A hydroponic cultivation device characterized in that the nutrient solution in the cultivation tank is drained through piping of a pump.
