Reagent for preventing and controlling water hyacinth and prevention and treatment method thereof

Abstract

The invention provides a reagent for preventing and controlling water hyacinth and a prevention and treatment method thereof. The reagent comprises a blending agent of nonanoic acid and paraffin oil, 2-methyl-4-chlorophenoxyacetic acid sodium salt, a flight prevention auxiliary agent and water according to a mass ratio of (660-700): (15-25): (95-105): (9100-9250). According to the reagent for preventing and controlling water hyacinth and the prevention and treatment method thereof, higher-efficiency water hyacinth prevention and treatment effect is achieved, water ecology and surrounding environment safety are better guaranteed, the usage amount of the reagent is reduced to the maximum extent, cost is reduced, prevention and treatment cost is low, ecological and efficient prevention and control effects of the alien invasive organism water hyacinth are effectively achieved, the dosage of the reagent liquid is small, prevention and control efficiency is high, cost is low, and the reagent is suitable for being applied and popularized in rivers, reservoirs, lakes and other areas where water hyacinth is concentrated and is wide in application range, efficient to use, low in toxicity and low in residues.

Description

technical field [0001] The invention relates to the technical field of aquatic plant control, in particular to a medicament for controlling water hyacinth and a control method thereof. Background technique [0002] Water hyacinth, also known as water hyacinth, scientific name: Eichhornia crassipes (Mart.) Solms) floating water herb, is listed as one of the world's top 100 invasive alien species. Its reproductive ability and adaptability are strong, and it is easy to cause hazards such as encroaching on the lake surface, blocking river courses, and covering fish ponds. The dense water hyacinth will restrict the flow of water bodies, destroy the food chain of underwater animals, and cause underwater plants to fail due to insufficient light. Death will reduce the dissolved oxygen in the water body, affect the growth of underwater organisms, and destroy the ecological environment of rivers. At the same time, it has the ability to enrich heavy metals. After death, the decayed bo...

Problems solved by technology

Its reproductive ability and adaptability are strong, and it is easy to cause hazards such as encroaching on the lake surface, blocking river courses, and covering fish ponds. The dense water hyacinth will restrict the flow of water bodies, destroy the food chain of underwater animals, and cause underwater plants to fail due to insufficient light. Death will reduce the dissolved oxygen in the water body, affect the growth of underwater organisms, and destroy the ecological environment of rivers

At the same time, it has the ability to enrich heavy metals. After death, the decayed body sinks to the bottom of the water to form a layer with high content of heavy metals, which directly kills benthic organisms and greatly damages the underwater ecology.

[0003] Existing water hyacinth control mainly includes four methods: artificial removal method, mechanical agitation method, chemical control method and biological control method. Manual removal often requires excessive manpower and material resources, and the efficiency is low, so it is not suitable for the governance of large waters. It is difficult to fully kill the water hyacinth by the mechanical stirring method, and the control effect is not complete; the chemical control method has a serious impact on the water quality due to the use of chemical pesticide preparations, and the existing biological control by introducing natural enemies has the disadvantages of slow effect and so on.
