Description

A kind of soil-repairing agent for eliminating noxious bacteria

Technical field

The invention belongs to technical field of soil remediation, be specifically a kind of soil remediation for eliminating noxious bacteria Agent.

Background technology

In recent years along with the deterioration of whole ecological environment, the biological pollution in soil is the most increasingly severe, but soil is The primary growth source of human foods, the increase of its pollution level also can affect the quality of food significantly, and therefore soil is raw It is one of emphasis of environment protection treating that thing pollutes, geobiont pollute refer to pathogen and in spite of illness etc. harmful organism population invade from the external world Enter soil, destroy the balance of soil ecosystem, cause the phenomenon that soil quality declines.Harmful organism population source be with without Sewage and the industrial wastewater that pathogen is contained in the human and animal excreta fertilising that processes, sanitary sewage, rubbish, hospital, and ill domestic animal corpse Deal with improperly.By above-mentioned main path containing a large amount of infective bacterials, virus, worm's ovum band people's soil, cause plant Various bacterial pathogen diseases, and then cause human body to suffer from various bacillary and viral disease, threaten human survival.

Infective bacterial and virus contaminated soil after even more serious to the harm of health.It is generally from feces and city The malignant bacteria of sanitary sewage belongs to: Salmonella, Shigella, bacillus, Bacteroides, fusobacterium, false list Born of the same parents' Bacillus, Bacterionema, Streptococcus, Mycobacterium etc..Additionally, with Excreta, secretions or its corpse of infected animal Body enters soil and infects the pathogen also having the diseases such as anthrax, tetanus, malignant edema, erysipelas to human body.In soil Have been found that kind more than 100 may cause the virus of human disease, such as poliovirus, people enterocyte pathological changes orphan sick Poison, Coxsackie virus etc..The most it is a risk that infectious hepatitis virus.The plant virus of soil infection has tobacco mosaic disease Poison, tobacco necrosis virus, wheat streak mosaic virus and Caulis et Folium Lactucae sativae large pluse virus etc..

Control currently for the physicochemical property repairing mainly change soil and the moisture condition of noxious bacteria in soil The propagation of pathogenic microorganism, reinforcement ground mulching, to suppress airborne dust, cuts off the airborne spread approach of pathogenic bacterium, it is also possible to the most right Soil pesticide sterilizing and virus killing, conventional sterilizing and virus killing, again can be multiple to bringing in soil while playing rehabilitating soil Harmful chemical substance, destroys the growth of later stage vegetation, it is therefore desirable to a kind of soil-repairing agent taken as the leading factor with natural component, The production of later stage vegetation can be promoted again while noxious bacteria in eliminating soil.

Summary of the invention

Present invention solves the technical problem that to be to provide a kind of bactericidal effect good, environment friendly and pollution-free with natural Chinese medicinal herb composition It it is main soil-repairing agent.

Technical scheme is as follows:
