Cuttage device for hydroponics of finger lemons

The utility model relates to the technical field of finger lemon hydroponics, and discloses a finger lemon hydroponics cuttage device which comprises supporting frames, one sides of the four supporting frames are fixedly connected with the same cultivation barrel, a plurality of limiting grooves are formed in the periphery of the inner side of the cultivation barrel at equal intervals, and limiting blocks are slidably connected into the limiting grooves. And one sides of the multiple limiting blocks are fixedly connected with the same circular ring, a foam plate is arranged on the inner side of the circular ring, and a rack is fixedly connected to the left side of the bottom of the circular ring. According to the cultivation device, the sealing cover is opened firstly, at the moment, a water source and nutrient solution in the cultivation barrel flow out through the liquid outlet pipe, when the water source and the nutrient solution flow out, the foam plate descends due to the buoyancy of the foam plate, the
