Biological herbicide for extinguishing ageratina adenophora

Abstract

The invention discloses a biological herbicide for extinguishing ageratina adenophora. The herbicide is prepared from the following components in parts by weight through a fermentation process: 50-100parts of a plant organism extract, 1-5 parts of an organic acid, 3-5 parts of a fermentation agent and 3-5 parts of an aldehyde resin, wherein the plant organism comprises green walnut peel, cyperusrotundus, stellera chamaejasme, artemisia argyi, datura stramonium, fructus cnidii, aconite, crocus sativus, nepenthes attenboroughii, sweet wormwood herb, chinaberry barks, coriaria nepalensis fruits, coriaria nepalensis barks and herba patriniae. By adopting the herbicide, ageratina adenophora can die rapidly, roots can be rotten, and toxic plant herbs such as ageratina adenophora and various weeds can be thoroughly killed; furthermore, the herbs and weeds can be converted into an organic fertilizer which is returned into soil to provide nutrients and trace elements to the soil; the herbicide has a soil improvement function; free oxygen in an environment can be rapidly consumed, organic matter type nutrients can be generated, soil can be loosened, and growth and propagation of harmful bacteria of a shallow soil layer can be effectively inhibited; and the herbicide is free of pollution to environments and water sources, and is safe to human bodies.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a biological herbicide for killing Eupatorium adenophorum. Background technique [0002] China has a vast territory, and its natural and geographical conditions vary greatly. Most exotic plants from all over the world may find their own habitat here, and some even become invasive plants. Since the reform and opening up, with the increase of foreign trade and exchanges, the types and hazards of alien invasive plants have also increased dramatically. Alien invasive plants have posed a very serious threat to China's economy, ecology, biodiversity, social environment and human life safety. [0003] At present, there are 291 species of invasive alien plants confirmed in my country, and the annual economic loss caused by the invasion of alien plants is as high as 100 billion yuan. Eupatorium adenophorum (Eupatorium adenophorum Spreng), also known as destroying grass, liberating gr...

AI Technical Summary

Problems solved by technology

[0005] The technology and products of eradicating the malignant weed plants headed by Eupatorium adenophorum in the prior art have the following two major shortcomings: 1. It can only destroy its leaves or stems, but cannot fundamentally destroy them. 2. In this aspect, herbicides need to be powerful and used in large quantities, which will basically cause serious residues and damage to the soil
