Detailed Description
The submerged plants such as the goldfish algae, the leaf-plant black algae, the flower-plant foxtail algae, the small-leaf algae, the large-leaf algae, the cola algae, the gynura segetum, the bitter grass and the like can be subjected to population expansion through branch breaking or whole plant propagation, wherein the bitter grass can be conveniently constructed by cutting short leaves to form small plant clusters, and the submerged plant materials can be used for recovering the submerged vegetation in lakes. The broken branches or whole plant of the plant can grow and propagate after the adsorbed suspended matters naturally subside in the natural world. Therefore, the process can be simulated to carry out vegetation restoration in lake ecological restoration, the key of the process is the selection of an adhesion matrix, and the material can simultaneously satisfy the functions of assisting balance weight sedimentation and promoting the growth of the early stage of branch breaking.

The bottom material has the functions of balancing weight of plant material and nutrition source for initial growth; the gum component has the functions of improving the viscosity of the matrix and preventing the plant from breaking branches and suspending caused by wind wave disturbance; the outer wrapping particulate matter acts to further increase the integrity of the counterweight and attachment matrix of the plant material; the additive has the functions of promoting the rapid rooting of plant scission materials and improving the initial growth rate, and can be divided into rooting promoting additives (rooting powder and the like) and growth promoting additives (biomass charcoal, seaweed extract and the like) according to different action types. By utilizing the method provided by the invention, large-scale submerged plant planting construction can be rapidly and conveniently carried out, and the submerged plant recovery cost is greatly reduced.
