Preparation for inhibiting growth of plants in water body

Abstract

The invention discloses a preparation for controlling and inhibiting growth of plants in a water body, and belongs to the technical field of environment-friendly water treatment. The preparation is mainly applied to growth inhibition and control of plants of lakes, rivers, ponds, landscape water and other surface water bodies. The preparation comprises pigment, an anti-settling agent, a dispersing agent and a sustained-release agent, has low cost, can be easily implemented, has a good plant inhibiting effect in practice, and has a large development space in the aspects of lake eutrophication governance and water body and aquatic plant governance.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment and is mainly applied to the plant growth control of surface water such as lakes, rivers, reservoirs, ponds and landscape water bodies. Background technique [0002] In addition to algae eutrophication, the flooding of aquatic plants has become another important problem in my country's aquatic environment. Artificial lakes are flooded with aquatic plants and grow. Although they are salvaged every day, the growth rate of aquatic plants exceeds the speed of salvage. As a result, more and more aquatic plants are fished, which seriously affects the water surface landscape and becomes a public nuisance. Excessive aquatic plants limit the navigation of ships, limit people's leisure and entertainment, and destroy habitats, resulting in excess nutrients and organic matter in the water body. [0003] The eutrophication of surface water bodies in my country is very serious....

Problems solved by technology

Chemical methods such as copper sulfate are easy to deposit copper ions on the bottom of the water, causing secondary pollution, and have certain toxicity to other organisms in the water body; while the cost of algae removal boats is high, it cannot collect filamentous algae or other algae attached to growth, and It cannot be used in small water bodies; the air flotation machine occupies a large area and consumes a lot of energy, and the collected algae need to be treated twice harmlessly, so it cannot be used in large areas of water bodies

[0008] Most of the weeding methods currently on the market are mechanical weeding methods or chemical weeding methods. For example, Chinese utility model patents CN203462451U and CN203684189U use grass cutters or reamers to weed weeds, while chemical weeding mostly uses paraquat and glyphosate etc. as the main components, such as the Chinese invention patent CN1891047A, the disadvantages of using mechanical weeding are: mechanical weeding has a greater impact on aquatic organisms, mechanical weeding removes all aquatic plants non-selectively, and cannot remove the roots of aquatic plants. Continue to grow wildly, while mechanical weeding devices such as weeding boats are only suitable in shallower waters, but cannot cut aquatic plants in deeper waters, and the operation is expensive; and chemical agents may be toxic to non-target plants or animals. There is a time limit. For example, people and animals should not be close to the water body for a period of time when the chemical agent is applied. The corruption of aquatic plants killed by the chemical agent in the water body may reduce the dissolved oxygen in the water body and may also damage the nutrient cycle of the ecosystem.
