[0002] Forestry planting and seedling raising requires the use of a seedling raising device to plant seedlings, such as the utility model patent with application number 202221982120.2, which is named a forestry planting and seedling raising device. The patented device is connected at the bottom of a rectangular support plate by a plurality of strip reinforcement plates, and the strip reinforcement plates secure the rectangular support plate structure to prevent the rectangular support plate from having a poor force effect and being easily deformed and damaged due to a plurality of strip slots opened on the rectangular support plate. A plurality of main legs support the rectangular support plate at the bottom of the rectangular support plate, and the strip placement plate is inserted into the strip slot. The strip placement plate and the rectangular support plate are arranged in a plug-in structure for easy connection.
