Description
Technical Field
The utility model relates to the technical field of aquatic plant harvesting, in particular to a handheld aquatic plant community harvesting device.
Background
The aquatic plants are important primary producers and key food chains of the aquatic ecosystem and play an important role in regulating and controlling energy circulation, structure and functional stability of the aquatic ecosystem; particularly in lakes with serious eutrophication or water pollution, the aquatic plant community has extremely important water quality improvement functions of reducing nitrogen and phosphorus nutrient salts in eutrophic water, increasing dissolved oxygen, improving transparency, promoting the sedimentation of suspended particles, inhibiting the resuspension of sediment, inhibiting the growth of algae and the like.
Under the water environment conditions of proper illumination, water depth, nutritive salt and the like, the canopy of some submerged plants, such as malayan eyeweed, watermifoil and the like, is exposed to the water surface due to overgrowth. The rapid growth of aquatic plants can have a series of influences: firstly, the water surface integrity is damaged and the overall landscape of a water area is influenced when the aquatic plant canopies are exposed; secondly, a light shielding layer is formed on the canopy of the aquatic plant floating on the water surface, so that the submerged plant with a low canopy dies due to light starvation, the diversity of the aquatic plant is reduced, and the ecological function of the water body is damaged; moreover, the density or biomass of the aquatic plants, particularly submerged plants, is too high, and the night respiration of the aquatic plants causes oxygen deficiency in local water areas, thus threatening the survival of aquatic animals (fishes); in addition, the aquatic plants start to decay and degrade in autumn and winter, and nutrient salts contained in the easily degradable parts of the plant bodies are released into the water body to generate secondary pollution; the refractory residues are settled on the surface of the bottom mud, so that the swampiness of shallow lakes and the sedimentation process of river channels are accelerated. Therefore, proper harvesting control of the biomass (density) and community structure of the aquatic plants plays an important role in constructing a benign aquatic ecosystem.
At present, methods such as physical (large-scale mechanical harvesting control), chemical (herbicide control), biological (fish-eating grass control) and the like play an important role in controlling the biomass of aquatic plants and community structures, but have certain defects in the aspect of controlling the biomass or density of the aquatic plants near a water source area. For example, when the shipborne harvesting machine is applied to harvest large-water aquatic vegetation such as shallow lakes and the like, because the ships and shipborne mechanical equipment need fossil fuel for driving, the fossil fuel still has the risk of fuel oil leakage in the using process, and is not suitable for being used in water source areas, particularly primary protection areas of water areas or areas near the shore of riverways with shallow water levels; the chemical method is a method for controlling biomass or density of aquatic plants by applying herbicide, a certain amount of herbicide (chemically synthesized organic substances) is required to be put into a water body, and the chemical method is also not suitable for being used in a water source place or a sensitive water body in consideration of the threat of herbicide residue and organism enrichment risk to the water quality of the water source place; the grass carp eating regulation and control method is a method for controlling the biomass of aquatic weeds by utilizing grass carps, and the grass carps can excrete a large amount of excrement with high nitrogen and phosphorus contents in the grass eating process, so that serious harm is caused to the water quality of a water source area.
Therefore, how to provide a device which has a simple structure, is convenient to use, is efficient to operate, and is suitable for harvesting and controlling the aquatic plant canopy in the water source area and the riverway near shore is one of the technical problems to be solved in the field. The device can be used for quickly removing target aquatic plants, eliminating secondary pollution caused by decay and degradation of the aquatic plants in water source areas and important water areas, and simultaneously providing a proper ecological niche for growth of low-canopy aquatic plants.
