A method for restoring submerged plant community by utilizing submerged vegetation turf

Abstract

The invention provides a method for recovery of submerged plant communities through submerged vegetation turf. The composite submerged vegetation turf is made and is transferred and implanted into ecological systems such as a river and a lake to be recovered. Young seedlings of submerged plants are cultivated in a paddling pool through a plant fiber blanket, the young seedlings are fast cultivated through submerged plant seeds, winter buds, broken branches and other propagules, two submerged plants are planted on each piece of turf, three types of turf of elodea nuttallii and potamogeton crispus, vallisneria spirals and hydrilla varticillata, and potamogeton maackianus and hydrilla varticillata are cultivated, the cultivated young seedlings and the plant fiber blanket are taken out of the pool in pieces during transplantation, the turf is formed, rolled into cylinders and transported to a target water region, and then the turf is placed at the bottom of water piece by piece and fixed through T-shaped fixing stickers. The method has the following advantages that the illumination, water depth and the nutrient conditions of the paddling pool can be controlled easily, the submerged plant turf is conveniently transported and planted on site, and on-site plant planting time is saved.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment and ecological environment restoration, and relates to restoration of submerged plant communities in aquatic ecosystems, vegetation and turf planting technology and water quality improvement technology. Background technique [0002] Submerged plants have high diversity, large biomass, and strong water purification ability. The growth of submerged plants plays a key role in water purification: submerged plants can absorb nutrients and compete with algae for nutrients; they can form natural It can provide a medium environment for microorganisms, which is conducive to the production of microorganisms; it can provide shelters and spawning grounds for zooplankton, reducing the risk of zooplankton being predated by fish, thereby increasing the predation pressure on algae; The release of sulfides, polyacetylenes, polyphenols, and oxygenated fatty acid allelochemicals limit algae growt...

AI Technical Summary

Problems solved by technology

[0004] Submerged plants grow in the underwater environment. At present, artificial planting is generally used, but the efficiency of artificial cutting planting is low and the consumption of manpower and material resources is large; the restoration of soil using soil seed bank is a large amount of engineering and transportation is inconvenient.

Although single turf planting can improve planting efficiency, it cannot meet the requirements of community restoration, it is not easy to maintain biodiversity, and it is not conducive to community stability
