Description
Technical field
The process that the present invention is a kind of soil disease is repaired granule and processes restorative procedure, belongs to agricultural soil Treatment process field。
Background technology
When harmful substance is too much in soil, exceedes the self-purification capacity of soil, cause composition of the soil, 26S Proteasome Structure and Function to change；Microbial activities is suppressed, and harmful substance or its catabolite accumulate gradually in soil, by " soil → plant → human body ", or is indirectly absorbed by the body by " soil → water → human body ", reaches the degree being detrimental to health, it is simply that soil pollution。It is exactly one of them that soil disease pollutes！
Soil disease pollutes and is mainly manifested in soil-borne disease and continuous cropping disease；Soil-borne disease includes: gray mold, epidemic disease, powdery mildew, root rot, verticillium wilt, droop, bacterial wilt, sclerotiniose, blight dis-ease, marrow necrosis disease, seedling sudden fall ill, pythium rot, cotton disease, Phomopisis vexans, damping-off and various bacterial disease etc.；Continuous cropping disease is owing in soil, pernicious bacteria increases, as: the multiple fungus in Fusarium spp., phytophthora, pythium spp, Fungi Imperfecti and underground, antibacterial；Toxin accumulation around crop root (from poison harm) eelworm harm；Nutrient deficiency or unbalance etc.。
Crops soil-borne disease and continuous cropping disease are global contagious diseases, morbidity suddenly, very refractory, cause crops total crop failure, total crop failure time serious。The pathogen major survival of soil-borne disease and continuous cropping disease in soil, the rhizome portion of make inroads on crop。At present the preventing and treating of soil-borne disease and continuous cropping disease is lacked effective measures。The pesticide volume that China uses at present every year reaches 50-60 ten thousand tons, wherein there are about the pesticide of 80% and be directly entered environment, the land area of annual use pesticide is more than 2.8 hundred million hectares (2,800,000 square kilometres), chemical prevention is still main method, but traditional chemopreventive effects is undesirable, also can cause pesticide residues, ecological environment is caused serious pollution and destruction, and the crops commodity of high pesticide residues to the healthy of consumer and safe cause serious threat。
For controlling the generation of soil-borne disease, the general measure taked both at home and abroad is to adopt methyl bromide, dazomet, chloropicrin, lime nitrogen etc., even also has the high poison of employing, highly toxic pesticide that soil is carried out fumigation。Since the forties in 20th century, methyl bromide is always up one of most popular fumigant in the world, also because soil is had high-penetrability by it, can be penetrated in the organism not rotting to decompose, it is thus possible to efficiently, kill the various biologies in soil wide spectrum and favored, amount for soil disinfection accounts for the 70% of methyl bromide total quantity consumed in the world, and domestic also large-scale methyl bromide is to soil disinfection。And along with " Montreal Agreement " requiring, developed country was in 2005, developing country disabled methyl bromide in 2015 comprehensively, including dazomet, chloropicrin, lime nitrogen etc., chemical agent is sterilized, and the methyl bromide substitute technology including the physical disinfection such as solar energy, steam starts the application that puts it over；But physical disinfection technical costs height weak effect。Obtaining the chemical disinfection technology recommended, a common problem is: the harm such as people and animals is relatively big, poisoning and phytotoxicity accident very easily occurs, and environment and soil microenvironment are also had serious impact。Therefore, the chemical in situ that can effectively prevent and treat soil-borne disease and continuous cropping disease developing high-efficiency environment friendly fixes oxidation and the method and technology of microbial association process reparation, efficiently utilizes for environmental resource and promotes that agricultural sustainable development has great importance。
The soil microenvironment that has its source in of soil-borne disease and continuous cropping disease is destroyed, and will effectively prevent and treat soil-borne disease and continuous cropping disease, is necessary for rebuilding soil microenvironment。Soil in-situ solidifies while oxidation is the harmful microorganism group in killing soil also can injure beneficial microbe。So beneficial microbe colony and organic matter must be supplemented in time after harmful microorganism group in killing soil in soil。
Soil treatment is repaired: refer to adopt physics, chemical or biological method to fix, shift, absorb, degrade or convert the pollutant in the soil of place so that it is content is reduced to acceptable level, or poisonous and hazardous pollutant are converted into the process of innocuous substance。Restorative procedure is divided into again in-situ immobilization and showering two kinds。Showering relates to cutting the earth and muck haulage, not only can destroy original Soil structure, the problem that also can there is secondary pollution。
At present, the technology of repairing polluted soil mainly includes several as follows:
Phytoremediation。The ideal original position soil Treatment process being well recognized as, but there is obvious shortcoming: plant is short and small, Biomass is relatively low, the speed of growth is slow, growth cycle is long；Phytoremediation is additionally subjected to the environmental condition restrictions such as soil types, temperature, humidity and nutrition。The time of phytoremediation needs 3～5 years, it is meant that the time of falling into disuse of soil is exactly 3～5 years, affects economic benefit。It addition, phytoremediation is relatively costly, every cube of soil reaches about 200 yuan, the rehabilitation expense of every mu of soil up to 8～100,000 yuan。High cost be local government and peasant at all unaffordable。
Chemical leaching method。Chemical agent such as surfactant, mordant etc. is adopted to carry out wastewater treatment again after the heavy metal in soil being leached out。This method not only cost is very high, far above phytoremediation, and brings into soil such as new pollutant such as surfactant, mordant etc., and the physical arrangement of soil can be greatly affected。Become new polluter。
Soil moved in improve the original method。By buried for contaminated soil original place more than one meter or dig out and transport, then the backfilling new soil by cleaning；Reparation for pollution in wide area soil not only needs substantial amounts of human and material resources, financial resources；Repair one mu of contaminated land in this way and to spend unit up to a million, and the source of clean soil is also difficult to ensure。It addition, soil moved in improve the original method is easily destroyed Soil structure, causes that soil fertility and microecological environment decline, and the contaminated soil transferring to lower floor easilys lead to the release of Organic substance and heavy metal, transitions into subsoil water, causes new underground water pollution。
Microorganism elution method。By adding the microorganism species that Organic substance and heavy metal have enrichment in soil, wash out by Organic substance and heavy metal。This mode not only cost is high, and microbial inoculum consumption is big, owing to microorganism leacheate is difficult to collect for large-area soil pollution, is actually difficult to operation。
Electrochemical process。Soil make water solublity heavy metal ion enrichment to cathode surface by the function of current。This technology is simply groped at laboratory at present。Owing to function of current distance is too little, and actual contaminated land area is too big, and this technology is difficult to carry out in engineering, and no matter its high running cost is difficult to bear。
In sum, how to develop practicable, apply to integrated treatment restorative procedure and technology that soil disease pollutes, have become as following soil pollution and process reparation and control encountered new problem。
