  In the cultivation apparatus using the ultrasonic atomization of the present invention, a plurality of plant holding holes are provided in the first long cultivation tube, and a plant holding member is attached to each of these holding holes, and these plant holding members are attached. Hold each plant, connect an ultrasonic atomizer to a long cultivation pipe, atomize the fertilizer liquid from the fertilizer liquid tank in the atomization particle generation tank, and blow it from the air duct to the long cultivation pipe Thus, there is an advantage that a large number of plants held in the cultivation tube can be cultivated.

FIG. 1 is a configuration diagram of a cultivation apparatus using ultrasonic atomization according to an embodiment of the present invention. FIG. 2 is an enlarged perspective view of a part of the cultivation tube of FIG. FIG. 3 is a cross-sectional view of the ultrasonic atomizer shown in FIG. FIG. 4 is an enlarged sectional view of the cultivation tube of FIG. FIG. 5 is a cross-sectional view of a conventional hydroponic cultivation apparatus.

  In the present invention, the first long cultivation tube is held horizontally, and a large number of plant holding holes are provided, and a large number of plant holding members are attached to these plant holding holes, respectively. An ultrasonic atomizer equipped with an atomized particle generation tank is connected via a duct, and a fan is installed in the atomized particle generation tank so as to blow circulating air, and fertilizer is supplied from the fertilizer liquid tank to the atomized particle generation tank. The liquid is fed, and the circulation duct connected to the fertilizer liquid tank is connected to the other end of the first long cultivation pipe.

  FIG. 1 is a configuration diagram of a cultivation apparatus using ultrasonic atomization according to an embodiment of the present invention. As shown in FIG. 2, a large number of plant holding holes 2 are formed in a first long cultivation tube 1. The plant holding member 3 is mounted in the plant holding hole 2, the plant 4 is held in each of the plant holding members 3, and one end of the first cultivation tube 1 is connected to the ultrasonic atomizer 6 via the air duct 5. The other end of the first cultivation pipe 1 is connected to the second cultivation pipe 8 via the connection duct 7, and the second cultivation pipe 8 is connected to the fertilizer liquid tank 10 via the return duct 9. As shown in FIG. 3, the ultrasonic atomizer 6 has a fertilizer liquid 12 placed in an atomized particle generation tank 11, an ultrasonic vibrator 13 is attached to the bottom of the atomized particle generation tank 11, and ultrasonic vibrations. When an oscillation output is applied to the ultrasonic transducer 13 from an oscillator 14 attached to the lower portion of the child 13, the ultrasonic oscillation is performed. The water column 12 a is ejected from the fertilizer liquid 12 by the ultrasonic waves generated in the child 13, and the atomized particles 12 b are generated from the water column 12 a. 1 is sent to the cultivation pipe 1, blown to the second cultivation pipe 8 through the connection duct 7, and returns to the fertilizer liquid tank 10 through the return duct 9.

  Furthermore, as shown in FIG. 4, the first cultivation tube 1 has a flat top surface 1 a and a pentagonal cross section, and the atomized particles 12 b collide with the inner wall of the cultivation tube 1 and liquefy at the bottom 1 b.
