Method for recovering submerged plants with hard substrates

Abstract

The invention discloses a method for recovering submerged plants with hard substrates. The method comprises the following steps: A, selection of submerged plants: determining according to the ratio ofthe illumination intensity at 1 / 2 plant height of the submerged plants to the illumination intensity of the surface layer of the submerged plants; B, selection of planting materials, wherein ecological environment-friendly grass bags are adopted as turf external structures, and viscous bottom mud with low nutrient salt content fills in the turf external structures to serve as a planting substrate; C, turf manufacturing: when turf manufacturing is carried out, the viscous bottom mud is uniformly laid in a grass bag, the grass bag and the filling bottom mud are pushed aside the planting bag, and the root system of the submerged plant is buried in the grass bag; D, turf transplanting: hooking four corners of the grass bag with iron hooks, slowly putting the grass bag into a water body, and removing the iron hooks after the turf sinks to the bottom to finish transplanting; and E, recovery area management: strengthening management of the submerged plant recovery area. By means of the technical scheme, submerged plant planting can be carried out in an area where the water depth exceeds 2 m and underwater operation is difficult to carry out manually, and the planting problem of submergedplants under the hard substrate condition can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of water bodies, and more specifically relates to a method for restoring submerged plants with hard substrates, which is suitable for ecological restoration of artificial and natural water bodies such as reservoirs, landscape lakes and natural lakes, and is also suitable for plants with submerged water For the substrate of plant planting conditions, it is more advantageous to plant submerged plants in water bodies with hard substrate, dredging-fill floating mud substrate or sandy substrate. Background technique [0002] As one of the important primary producers of aquatic ecosystems, submerged plants are not only the basis for the stability of aquatic ecosystems and the maintenance of aquatic biodiversity, but also provide shelter for other biological groups, reduce sediment resuspension, and interact with planktonic species. Plant competition for nutrients and release of algal subs...
