Submerged macrophytes restoring process guided by water conservation fishery

Abstract

The invention discloses a submerged macrophytes restoring process guided by water conservation fishery. By stocking silver carp and bighead carp and reducing COD (chemical oxygen demand), TP (total phosphor), chlorophyll and other chemical indexes of the water body, the process effectively reduces the algae biomass in the water body, improves the water body transparency, and achieves the aim of preventing algal bloom and improving the water quality, so an excellent growing condition is provided for aquatic macrophytes (in particular, the submerged macrophytes); and by adding fish and other key organisms eating attaching organisms, which is a key link in a food chain, the attaching organisms growing vigorously on the surface of the submerged macrophytes can be removed in time, and the aim of restoring the submerged macrophytes can be achieved.

Description

Technical field: [0001] The invention relates to a technique for repairing submerged vegetation. Background technique: [0002] At present, due to the increase in population, urbanization, and vigorous development of industrial and agricultural production, a large amount of untreated or effectively treated domestic sewage and industrial and agricultural wastewater are discharged into lakes, resulting in the widespread eutrophication of lakes in our country. The aquatic plants in the lakes are seriously degraded, and the reverse succession of grass-type lakes into algae-type lakes is common. The disappearance of aquatic plants makes algae, especially cyanobacteria, become the main producers of lakes, which frequently break out into algal blooms under the condition of eutrophic water quality, which in turn has a serious negative impact on the use of water resources and the health of the aquatic ecosystem. . In view of the important functions and roles of higher aquatic plant...

AI Technical Summary

Problems solved by technology

[0006] The present invention overcomes the "low transparency of the water body caused by the excessive reproduction of algae, which makes the light in the depth of the water body lower than the compensation intensity necessary for the growth of submerged plants" and "the newly repaired submerged plants" appear in the restoration process of the above-mentioned submerged plants. Due to the disadvantage of being unable to grow well due to the vigorous growth of attached organisms in eutrophic water bodies, it provides a water conservation fishery-guided submerged water that ensures the better growth of submerged plants and promotes the restoration of submerged vegetation.
