A seedling moving tray comprises a tray and a bracket; the tray comprises a plurality of connecting plates and a plurality of U-shaped folding plates, and the folding plates are arranged at intervalsof the same distance. Adjacent two folding plates are connected by a connecting plate, and each folding plate is provided with a stepped opening. As that two trays are stacked together, the lower endsof each folding plate in the upper tray can be clamped into the stepped opening of each folding plate in the lower tray, and each connecting plate in the lower tray can be clamped into the gap between adjacent two folding plates in the upper tray; the bracket comprises two supporting rods and a plurality of inserting rods. After each inserting rod passes through each folding plate in sequence, two free ends of each inserting rod are respectively connected with two supporting rods outside the tray, and a limiting block is respectively fixedly connected with the inserting rods on both sides ofeach folding plate.
