Description
Technical field
The invention belongs to technical field of soil remediation, the soil-repairing agent of specially a kind of absorption degradation organic agricultural chemicals and its
Preparation method.
Background technology
The advantages that chemical pesticide is stablized with its quick, property, is readily transported, be cheap, in preventing and treating crop diseases and pest
Crop smothering and eliminate sanitary insect pest, disease etc. conveniently plays huge effect, but the agricultural chemicals in being manured into soil, except adsorbed
Outside, it can also cause atmosphere pollution by volatilizing, diffusing into air or migrate into water body with water, cause water pollution.Have
Chemical property is stable, RT length, largely persistently uses agricultural chemicals, it is constantly accumulated in soil, and people are in edible product
, can serious threat health after the agricultural product for tiring out a large amount of agricultural chemicals.
BHC, DDT, more cyclophanes are shown according to the investigation result of national Soil Pollution Investigation publication in 2014
The main organic contamination object point position exceeding standard rate of the class of hydrocarbon three is respectively 0.5%, 1.9%, 1.4%, it can be seen that organo-chlorine pesticide is mesh
One of preceding important organic pollution.But because its exceeding standard rate is less than inorganic pollution, not because it is fully paid attention to.Organo-chlorine pesticide is
Typical persistence organic pollutant (POPs), the organo-chlorine pesticide of low dosage remain to bring excessive risk to biology, human body, and it is endangered
Evil is just increasingly causing the concern of people.Although China prohibits the use of in nineteen eighty-three, recent studies indicate that, HCHs and
DDTSThere is detection in the surrounding medium of each department at home, and its content is higher in the environment of some areas.In addition, in soil
Organochlorine Pesticide Residues have direct harm to terrestrial life, and influence on water body aquatile can be also discharged into by rainwash, and
Indirect hazard is caused to human body by the biological concentration and expansion effect of food chain.
Pesticide contaminated soil processing method mainly has Thermal desorption method and advanced oxidation processes at present, and Thermal desorption method cost is high, and
Easily generation atmosphere pollution.Advanced oxidation processes add substantial amounts of chemical agent, easy contaminated soil.Have many studies have shown that,
Microorganism remediation technology often shows as that efficiency is low, and the external Black Liquor with Efficient Bacteria of introducing can not effectively be bred, because to be repaired
Scene often need the conditions such as nutrition, moisture without microbial reproduction, cause its function effectively to play.It is but micro-
It is biological prosthetic that there is the advantages that cost is low, non-secondary pollution, if can rationally utilize will play unique advantage in soil remediation.
The content of the invention
To solve the defects of soil-repairing agent is not environmentally existing for prior art or efficiency is low, the present invention provides a kind of
Soil-repairing agent of absorption degradation organic agricultural chemicals and preparation method thereof.
A kind of soil-repairing agent of absorption degradation organic agricultural chemicals, include each component of following parts by weight：Attapulgite powder 35-
55 parts, expanded perlite 2-10 parts, complex microbial inoculum 0.1-0.5 parts, corn flour 1-10 parts and powder of straw 40-60.
Further, described expanded perlite is crushed by pearl protolith warp, sieved, then preheated, more than 1400 DEG C
High-temperature delayed is sintered and is made, particle diameter 1-3mm.
Further, described complex microbial inoculum is by one in bacillus, saccharomycete, pseudomonad and actinomyces
Kind or a variety of compositions.
Further, described complex microbial inoculum is made up of bacillus and pseudomonad.
Further, described bacillus is bacillus subtilis, bacillus megaterium, clostridium or short and small
Any one in bacillus.
Further, crush and obtain through machine after described powder of straw is dried for common crops straw refuse；It is described
Stalk can be maize straw, wheat stalk or rice straw.
Further, described attapulgite powder crushed obtained by 100 mesh by attapulgite mineral.
A kind of preparation method of the soil-repairing agent of absorption degradation organic agricultural chemicals, comprises the following steps：
1), microculture activates
LB (Luria Bertani) liquid after bacillus and pseudomonad are inoculated into containing high pressure steam sterilization respectively
In body culture medium, aerobic culture is carried out at 28~32 DEG C, obtains shaking flask strain；
2), the strain in above-mentioned shaking flask is seeded to the fermentation of the fluid nutrient medium containing LB by 2%~5% inoculum concentration respectively
In tank, the daily air agitation of fermentation tank 8 hours, throughput 50m3/ h, speed of agitator 100r/min, 28~32 DEG C of fermentation temperature,
Microbial inoculum is obtained after fermentation 48h；
3), solid culture
It is 0.1-0.5 in mass ratio by microbial inoculum, corn flour, water and stalk：1-10：40-80：40-60 parts are sent into
Mixer mixing, stir, fermented 2-3 days under aerobic condition；
4) 35-55 parts attapulgite powder and 2-10 parts expanded perlite, are added into the further uniform stirring of mixer to mix
Produce.
Soil-repairing agent can use the amount of application of 50-75kg/ mus according to pollution level.Can be organic with applying during use
Fertilizer or chemical fertilizer mix as base manure after turning over earth's surface topsoil.To improve the degradation rate of soil organic pollutant, turn over
After can dry 1-2 days after planting plants.
Microorganism, organic materials, natural minerals are combined by the soil-repairing agent of the present invention, organic with absorption degradation soil
Based on agricultural chemicals while nutrient loss and heavy metal-passivated can be reduced, is used in formula in the adsorbable soil of natural minerals
The organic agricultural chemicals of enrichment, excessive available nutrient and heavy metal.
Complex microbial inoculum can not only promote degradation of pesticide, can also prevent and treat plant soil borne disease.
On the one hand powder of straw provides carbon source and the energy as microorganism Co metabolism substrate for the biodegradation of soil；Separately
Outside, the addition of powder of straw can increase loosing soil degree, gas permeability, so as to promote the enzymatic degradation performance of microorganism.Perlite
As insecticide and the diluent and carrier of herbicide, the surface-active of itself, adsorptivity, ion exchange, complexing are utilized
Effect and electrostatic interaction can adsorb, organic agricultural chemicals and heavy metal in fixing soil, reduce agricultural chemicals and migrated in soil；In addition
Soil porosity can also be increased, improved soil structure, soil hardening is adjusted, prevent crops from lodging, control fertilizer efficiency.
Beneficial effect：
The soil-repairing agent of the present invention may finally reach control loss of soil nutrient, passivation heavy metal in soil, degraded
The effect of Organic pesticide residues；Can also improve simultaneously soil environment, improve soil nutrient utilization rate, improve crop yield and
Quality.Degraded to organic agricultural chemicals in soil is largely effective, is used especially for the agricultural chemicals such as long-term planting vegetable, fruit and chemical fertilizer
Larger facility agricultural soil is measured, repairing effect is more significant, can effectively improved soil production capacity and the security of food.
