A lifting device 200, which is arranged on one side of the cultivation rack 100 and can move in the vertical direction. A transfer mechanism 300 is arranged in the lifting device 200. The transfer mechanism 300 is slidably connected to the lifting device 200. The transfer mechanism 300 can transfer the cultivation tray 500 from the conveyor unit 400 to the lifting device 200. The transfer mechanism 300 can move to the positions of different levels of the cultivation rack 100 along with the lifting device 200, so that the cultivation tray 500 can be pushed on different levels of the cultivation rack 100. The transfer mechanism 300 pushes the cultivation tray 500 from the lifting device 200 to the corresponding level of the cultivation rack 100, so that the cultivation tray 500 slides on the cultivation rack 100 for a distance of at least the width of one cultivation tray 500. The next cultivation tray 500 squeezes the previous cultivation tray 500 under the pushing action of the transfer mechanism 300, so that the previous cultivation tray 500 moves to the other side of the cultivation rack 100. The transfer mechanism 300 only needs to move a distance of the width of one cultivation tray 500 without moving the cultivation tray 500 to the other end of the cultivation rack 100, and the entire layer of the cultivation rack 100 can be filled, reducing the travel of the transfer mechanism 300 and improving the tray laying efficiency.
