Germination method of river-lake wetland seed bank

The invention discloses a germination method of a river-lake wetland seed bank, and relates to the technical field of ecological system restoration. The method comprises the following steps: S1, sampling and experiment: sampling from plaque soil to be recovered and adjacent natural wetland soil respectively, performing wetland plant seed bank germination experiment on the collected soil samples respectively, and judging the degradation degree of the plaque soil to be recovered by calculating the species number proportion and the seed bank density proportion between the plaque soil to be recovered and the adjacent natural wetland soil. According to the method, the germination of the natural seed bank is promoted and the recovery process is accelerated by utilizing a structure and hydrological variable form, a new river and lake ecological system structure is constructed through shallow water bubbles, ecological ditches, polder field ridges and a fluctuating sheetflow wetland, and the germination of the seed ba
