Multi-layer seedling bed for greenhouse seedling culture

The invention relates to the technical field of greenhouse seedling raising, and discloses a greenhouse seedling raising multi-layer seedbed which comprises a seedling raising frame and seedling raising trays. The two first mounting rods are arranged at the lower end of the mounting frame and are close to the two ends, the two second mounting rods are arranged at the upper end of the mounting frame and are close to the two ends, the bottom rod is arranged below the mounting frame and is parallel to the mounting frame, the lower ends of the first mounting rods are fixed to the bottom rod, and the second mounting rods are connected with the seedling raising frame. A plurality of mounting plates are arranged in the length direction of the bottom rod at intervals, the seedling raising plates penetrate through the mounting frame and are inserted into the mounting plates, water storage chambers are arranged at the bottoms of the seedling raising plates, cotton cores extending into the seedling raising plates are ar
