A kind of medicament for controlling water hyacinth and its control method

Abstract

The invention provides a medicament for controlling water hyacinth and a control method thereof. The medicament includes nonanoic acid with a mass ratio of: (660-700): (15-25): (95-105): (9100-9250) Blending agent with paraffin oil: Sodium dimethyltetrachloride: fly control additive and water. The medicament for controlling water hyacinth and the control method thereof proposed by the present invention not only achieve a more efficient control effect of water hyacinth, but also better ensure the safety of water ecology and surrounding environment, and reduce the usage of medicament to the greatest extent , reduce cost and low control, effectively realize the ecological and efficient control of water hyacinth, an alien invasive organism, use less liquid medicine, high control efficiency and low cost, suitable for promotion in rivers, reservoirs, lakes and other areas where water hyacinth occurs more concentrated Wide range of applications, high efficiency, low toxicity and low residue.

Description

technical field [0001] The invention relates to the technical field of prevention and control of aquatic plants, in particular to an agent for preventing and 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 herb, is listed as one of the top 100 invasive alien species in the world. Its reproductive ability and adaptability are strong, and it is easy to cause hazards such as encroaching on the lake surface, blocking river channels, and covering fish ponds. Death reduces the amount of dissolved oxygen in the water, affects the growth of underwater organisms, and destroys the ecological environment of the river. At the same time, it has the ability to enrich heavy metals. After death, the decayed body sinks into the bottom of the water to form a layer with high content of heavy metals, which directly kills benthic organisms and causes...

AI Technical Summary

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.
