The utility model discloses a multifunctional circulating modern three-dimensional seedling growing device, relating to the technical field of seedling growing. The device is used for solving the problems that the conventional float breeding mode is large in occupied area, low in space utilization rate and low in degree of automation. A square tube adopted by the device is a main body material, the outer surface of the material is subjected to electrostatic spraying, and thus the corrosion resistance is high. A worm and gear reducer is driven by adopting a temperature-resistant moisture-proof motor, the motion is simultaneously transmitted to each part through a chain, and a transmission spindle is arranged at the upper part of each main body, so that the motion speed of a bracket chain wheel on each main body is consistent, and the state of motion is synchronous. The operating time of the motor and an electric diaphragm pump is controllable, the degree of automation is high, and unattended operation can be realized. Water is delivered into an injection spray pipe at a higher part by adopting the electric diaphragm pump, mist is generated through a nozzle, the atomization effect is good, and waste of water resources is avoided. Multiple baskets on each main body form a ring and cyclically move to alternatively realize lighting, so that the space is fully utilized, and the occupied area is small.
