Embodiment 1
[0041] The solution to the pollution of submerged plants caused by the turbidity of water (suspended particles) as the main contradiction:
[0042] Various suspended particles in the water body directly affect the vertical distribution of light in the water body, and after attaching to the stems and leaves of submerged plants, they increase the thickness of the extracellular diffusion layer and reduce the supply of dissolved inorganic carbon, thereby affecting the Growth, reproduction and distribution of submerged plants.
[0043] Suspended solids in water mainly include bio-organisms such as algae and bacteria and organic residues (mostly appear in algae-type eutrophic water bodies and water bodies with a lot of organic suspended matter), and inorganic particles such as sediment (mostly appear in rivers and lakes).
[0044] Measures: flocculation air flotation (or sedimentation) + water disinfectant.
[0045] The relevant drugs in this treatment measure are preferably as follo...
Embodiment 2
[0054] The solution to the pollution of submerged plants caused by the type of attached algae (periplex algae) as the main contradiction:
[0055] Measures: algicide + water detoxifier + biological agent.
[0056] Algicides include: copper preparations, triazine algicides, etc. Preferably, algicides are the first choice: chelated copper, copper sulfate, sulfur-iron mixture, promethazin.
[0057] Preferred water detoxifiers: EDTA-2Na, sodium thiosulfate, sodium humate.
[0058] Preferred biological agents: Bacillus subtilis, Lactobacillus, EM bacteria.
Embodiment 3
[0060] The solution to the pollution of submerged plants caused by the attachment of calcium salts:
[0061] Remedy: Acid conditioner.
[0062] Preferred acid regulators: organic acids such as lactic acid, citric acid, humic acid, acetic acid and their sodium salts.

Abstract
The invention discloses a comprehensive maintaining method for submerged plants. The comprehensive maintaining method comprises the following steps that firstly, a flocculating agent is added into a water body with the quantity of 1-20 mg / l to reduce the turbidity of the water body; secondly, according to the specific circumstance of dirt attached to the submerged plants, a disinfecting agent or organic acid or pesticide or algicide or surfactant or a substrate modifying agent or a microbial agent or microorganism growth promoting liquid is added into the water body with the amount of 0.1-1 mg / l, and flow disturbance is artificially made; thirdly, a nutrition regulator or a heavy metal complex is applied in the growing stage of the submerged plants with the quantity of 0.2-1 mg / l; fourthly, plagiognathops microlepis or barbels are introduced into the water body with the quantity of 50-100 pieces per 666.7 m<2> to eat fixation algae, and chub or bighead carp are introduced with the quantity of 10-30 g / m<3> to eat planktonic single-spore algae. By means of the comprehensive treatment method, the ecology of the water body is balanced, the transparency of the water body is quickly increased so as to promote the growth of aquatic plants in the water body, dirt attached to the stems and leaves of the aquatic plants is quickly removed, and finally the purpose of long-acting cleaning of the stems and leaves of the aquatic plants and the effect of enhancing water ecological restoration are achieved.
Description
technical field [0001] The invention belongs to the field of water environment ecological restoration and management, and in particular relates to a method for comprehensive maintenance of submerged plants, and is particularly suitable for the treatment of contamination on the body surface (stems and leaves) of submerged plants. Background technique [0002] Aquatic plants refer to the plant groups attached to the water environment, at least part of the reproductive cycle occurs in the water or on the water surface; it refers to all aquatic plant groups except small aquatic plants, mainly including two categories: aquatic vascular plants and higher algae ("Advanced algae") Aquatic Biology" Liu Jiankang, 1999). [0003] Aquatic vascular plants Plants are divided into four life types: emergent plants, floating plants, floating plants and submerged plants (Wetxel, 1983). [0004] Submerged macrophyte refers to aquatic plants in which the vegetative body is completely submerged...
