Embodiment 1

[0021] S1: Identify invasive alien species characteristics.

[0022] S2: Use manual or mechanical control to control the water peanuts on the ground.

[0023] S3: prepare chemical agent, the composition of described chemical agent is 10 parts of ammonium sulfate, 2 parts of glyphosate, 5 parts of ketalon, stir ammonium sulfate, glyphosate, ketalon at 100° for 10 min, Mix thoroughly with water when using.

[0024] S4: Use chemical agents to control water peanuts, and the chemical agent used for one hectare of water peanuts is 10%.

[0025] S5: According to the different growth states of water peanuts, use chemical control and mechanical control to organically integrate each other, coordinate with each other, and comprehensively control. Use mechanical control when it is not fully grown, and use chemical control when it is fully grown. Using this method has the following advantages: quick effect, In the early stage of implementation, in some places that urgently need to get ri...

Abstract

The invention relates to the technical field of environmental protection, and further discloses a comprehensive treatment method for dealing with exotic species invasionin in reservoir areas. The comprehensive treatment method for dealing with exotic species invasionin in reservoir areas comprises the following steps: S1, determining characteristics of exotic invasive species, S2, manually or mechanically preventing and removing alternanthera philoxeroides on the ground surface, S3, preparing a chemical agent, S4, chemically preventing and removing alternanthera philoxeroides by using the chemical agent, and S5, organically integrating, coordinating and comprehensively treating alternanthera philoxeroides by using chemical prevention and treatment and mechanical prevention and treatment according to different growth states of alternanthera philoxeroides. According to the method, chemical prevention and treatment, biological prevention and treatment and mechanical prevention and treatment are organically integrated, coordinated and comprehensively controlled, and meanwhile, the respective advantages are utilized to make up for the defects of each other, so that the spreading of alternanthera philoxeroides can be effectively eradicated, and further, a mixture of fluroxypyr, glyphosate, and Nimbyaalternantherae has a synergistic effect on preventing and eliminating alternanthera philoxeroides.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a comprehensive treatment method for dealing with the invasion of alien species in reservoir areas. Background technique [0002] Invasive alien species refer to species that are introduced from natural distribution areas through intentional or unintentional human activities, form self-regeneration capabilities in local ecosystems, and cause obvious damage or impact to local ecosystems or agricultural production. Because of their great threats to human health, ecological functions of natural ecosystems, biodiversity, and agricultural and animal husbandry benefits, invasive alien organisms have become a hot issue in global biosecurity, environment, and economy, and have attracted great attention from all countries in the world. Invasive plants are now an economic problem and a threat to natural ecosystems because the destruction of plant communities can lead to the disinteg...
