Comprehensive maintenance method of submerged plants

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...

AI Technical Summary

Problems solved by technology

Attachment on the surface of the stems and leaves of submerged plants restricts the use of light and nutrients by submerged plants, inhibits the normal growth of submerged plants, and even leads to the decline of submerged plants, thus making the restoration project of submerged plants fail
