Abstract: A method for planting submerged plants is disclosed. The method includes the steps of selecting a combination of two submerged plants; planting the combination of submerged plants; measuring a biomass and evaluating the biomass. By discussing the influence of planting proportion on the biomass of submerged plant community, the structure of submerged plant community can be optimized, and the success rate of submerged vegetation restoration and reconstruction can be improved by using the positive interaction between plant species.
