The invention provides a full-biodegradable foaming seedling tray suitable for mechanical transplanting and a preparation method thereof. The biodegradable foaming seedling raising tray comprises the following components in parts by weight: 50-80 parts of full-bio-based degradable resin, 10-30 parts of bio-based filler and 0.5-5 parts of auxiliary agent; the foaming multiplying power of the biodegradable foaming seedling raising tray is 1-15, and the biodegradable foaming seedling raising tray is used for raising seedlings and is used for mechanical seedling separating, transplanting and planting after being raised. The preparation method of the biodegradable foaming seedling raising tray comprises the following steps: mixing raw materials, extruding and granulating, preparing a foaming sheet, and forming a foaming seedling tray. The foaming seedling raising tray has safe degradation performance, can realize full-automatic mechanical transplanting of seedlings, and has low cost. |
