Submerged plant planting bag and ecological restoration system

The utility model relates to the technical field of plant cultivation, in particular to a submerged plant cultivation bag and ecological restoration system which comprises at least two sets of containing pieces and connecting pieces, each containing piece comprises a base layer and a non-woven fabric layer, each non-woven fabric layer is connected with the corresponding base layer, and a cavity used for containing a matrix is formed by each non-woven fabric layer and the corresponding base layer. Wherein the substrate comprises submerged plant seeds, and the non-woven fabric layer is made of degradable non-woven fabric; and the connecting pieces are connected with two adjacent groups of accommodating pieces. The submerged plant planting bag is large in loading capacity and short in submerged time, and due to the fact that the containing parts are arranged in a spaced mode, the submerged plant planting bag cannot be accumulated into blocks after being thrown into water, the actual pollutant absorbing range of
