Abstract

The invention discloses a double-layer net bed for repairing water by planting submerged plants. The double-layer net bed comprises an upper net sheet and a lower net sheet, wherein the upper net sheet is a quadrilateral net sheet with square meshes, and the side length of the square is 1 -5cm; the lower net sheet is a quadrilateral fishing net with square meshes, and the side length of the square is 2-10mm; four corners of the upper net sheet and the lower net sheet are fixed on four piles in quadrilateral arrangement respectively; and the upper net sheet is 3-5cm away from the lower net sheet. According to the size of the upper mesh, a bundle of vallisneria can be exactly inserted into the mesh, and the roots of the vallisneria can be ensured to contact the lower net sheet; and according to changes of the water level and the transparency of water to be repaired, ecological niche is continuously changed so as to overcome the limitation on submerged vegetation restoration by the transparency and improve the repairing effect.

Description

technical field

[0001] The invention relates to the technical field of ecological restoration, in particular to a double-layer mesh bed for planting submerged plants to repair water bodies and a method for repairing water bodies. Background technique

[0002] In recent years, China's water environment is not optimistic, and eutrophication of rivers and lakes is not uncommon. Water pollution not only seriously affects people's life and production, but also beautifies the visual landscape. After the continuous improvement of living standards, people began to gradually increase their awareness of beautification and protection of the ecological environment. In this context, water ecological restoration has quietly emerged. The ultimate goal of water ecological restoration is to build a benign ecosystem. To build a benign ecosystem, first of all, the submerged plant community must be able to recover quickly.

[0003] However, how to quickly restore the submerged plant communi...
