The invention relates to the technical field of seedling raising devices, and discloses a tea cutting seedling raising device in summer, which comprises: a machine body, wherein the top of the machinebody is fixedly connected with a ceiling body; supporting blocks are fixedly arranged at the bottom of an inner cavity of the machine body, and the number of the supporting blocks is three; the topsof the three supporting blocks are movably connected with seedling beds; a first filter screen is fixedly connected between the supporting blocks and the inner wall of the machine body. According to the tea cutting seedling raising device in summer, the first filter screen, a second filter screen, a water leakage hole and a vertical pipe are arranged, wherein the first filter screen and the secondfilter screen are used for filtering redundant nutrient solution after spraying, thereby preventing soil from entering a water tank. Then by the coordination between the water leakage hole and the vertical pipe, the redundant nutrient solution can flow into the water tank in a centralized manner, so that the recovery and utilization of the nutrient solution are completed, and the practicability of the seedling raising device is increased.
