A cultivation tube 4011 is inserted into the central through hole of the placement seat 3 to form a seedling box, wherein the cultivation tube 4011 is used to place the cultivation solution, that is, soilless seedling cultivation is carried out, and the soil tank 5 on the cultivation tube 4011 is used to hold the soil for normal cultivation. After a group of seedlings is cultivated, it is only necessary to turn on the motor 1 402 to drive the screw 403 to rotate, so that the lifting seat 405 moves downward, and then drive the connecting shaft 406 to move downward. After the worm wheel 407 is engaged with the worm 408, the worm 408 is driven to rotate by the motor 2 4010, so that the worm wheel 407 rotates, and then drives the connecting shaft 406 to rotate, and the cultivation tube 4011 is turned over to dump the culture solution in the cultivation tube 4011 or the soil in the soil tank 5, and then the next round of seedling cultivation is carried out; There are 33 placement seats 3 and cultivation tubes 4011, which are evenly spaced on the placement frame 2.
