Description

Technical Field

[0001] The utility model relates to a handheld aquatic plant community harvesting device, belonging to the technical field of aquatic plant harvesting. Background Art

[0002] Aquatic plants are important primary producers and key food chains in aquatic ecosystems, and play an important role in regulating the energy cycle, structure and functional stability of aquatic ecosystems. Especially in lakes with severe eutrophication or water pollution, aquatic plant communities have extremely important water quality improvement functions such as reducing nitrogen and phosphorus nutrients in eutrophic water bodies, increasing dissolved oxygen, improving transparency, promoting the sedimentation of suspended particles, and inhibiting sediment resuspension and algae growth. However, in autumn and winter, aquatic plants begin to rot and degrade, and the nutrients contained in the easily degradable parts of the plants are released into the water, causing secondary pollution; the difficult-to-degrade residues settle to the surface of the sediment, accelerating the swamping of shallow lakes and the siltation of rivers. Therefore, the biomass (density) and community structure of aquatic plants need to be properly harvested and regulated using harvesting devices, which plays an important role in building a benign aquatic ecosystem.
