Abstract
The invention relates to a humic acid preparation for reducing residue quantity of organic pesticides in soil and an application thereof. The humic acid preparation contains humic acid, microbial inhibitor and a micronutrient element chelating agent, wherein in the humic acid preparation, the volume percent of the humic acid is 5%. After the humic acid preparation is applied into the soil polluted by the organic pesticide, inactivation is generated on organic pollutant in the soil through modes of adsorption, complexation (chelation), oxidation reduction and the like, the quantity of the organic pesticides in the soil, which migrate towards aboveground parts of crops and plants through root systems of the crops and the plants, is significantly decreased, and then the residue quantity of the organic pesticides in the soil and the crops can be finally reduced effectively.
Description
Technical field
The present invention relates to environmental protection and agricultural technology field, more particularly to a kind of corruption for reducing Organic pesticide residues in soil
Phytic acid preparation and application.
Background technology
China is planting industry big producer, while be also that pesticide producing uses the big country, China to have 1000 Multiple Pesticides, every year
Pesticide use area is up to 1.8 hundred million hectares times.State Statistics Bureau's data display, 2008,2010 and 2014, national agricultural chemicals was produced
Amount is respectively 190.2 ten thousand tons, 234.2 ten thousand tons and 374.4 ten thousand tons, wherein, be account for absolutely for the agricultural chemicals on the crops such as vegetables, fruit tree
It is most of.Agricultural chemicals prevents pest and disease damage in the agricultural production, keep agricultural output in terms of, serve the effect that can not be ignored, but
It is that, due to China's Pesticidal products unreasonable structure for a long time, Pesticide use is lack of standardization and supervision and management is ineffective, is applied every year
Agricultural chemicals except a very small part（＜ 10%）Play outside the effect of desinsection, major part enters ecological environment.So that native
Earth Pesticide Residues are constantly in level higher, and exceeded phenomenon is long-term and generally existing, and soil environment quality problem is made us
Worry.
" residues of pesticides " are referred in process of production to crop, plant using after agricultural chemicals, residual by one period
The general name of each toxoid in crop, plant and soil is stayed in, it is former which includes degradation of pesticide thing, toxic metabolite, agricultural chemicals
Body etc..Residues of pesticides are polluted the environment, destroy the ecological balance, while can also be detrimental to health.When people, animal are edible containing a large amount of
During the agricultural product that high poison, highly toxic pesticide satholith are planted on the ground, people, animal acute poisoning accident can be caused, long-term consumption agricultural chemicals is residual
Exceeded agricultural byproducts are stayed, the slow poisoning of humans and animals may be caused, cause the generation of disease, or even have influence on the next generation.
Nicotinic insecticide is the new and effective organic agricultural chemicals of the class for continuing to bring out at present, is widely used in vegetable, fruit, rice
The crops such as paddy.Imidacloprid（Imidcaloprid）It is the representative of nicotinoids broad spectrum pesticide, is also wherein to apply more one kind,
Its sales volume occupies the second of the first and all agricultural chemicals of all insecticides（It is only below glyphosate）, the residual of such agricultural chemicals asks
Topic is increasingly taken seriously.
In recent years under the supervision of governments at all levels, pesticide reduction has been carried out in all parts of the country, including from anti-（It is resistance to）Sick crop
Kind, efficent rotation, promote trapping lamp or fly net, using biological pesticide, promote high-efficiency low-toxicity low-residual chemical pesticide new product
Kind etc. a series of integrated control technique measures reduce Organic pesticide residues in agricultural product, plant, soil.However, by reducing
The residual quantity of the Pesticide Residue in Soil of Planting Crops, and then the method for reduction pesticide residual contamination environment but rarely has research.
The content of the invention
The purpose of the present invention is to propose to a kind of humic acid preparation for reducing Organic pesticide residues in soil and its application,
By specific method of application, Organic pesticide residues, prevention Organic pesticide residues enter the angle of food chain from soil is reduced
Solve the problems, such as Organic pesticide residues contaminated soil environment at all.
To achieve the above object, the present invention is adopted the following technical scheme that：One kind is for reducing Organic pesticide residues in soil
Humic acid preparation, the humic acid preparation include humic acid, microbial inhibitor and micronutrient element chelating agent, wherein
In terms of humic acid preparation, the percent by volume of humic acid is 5%.
Preferably, the micronutrient element chelating agent includes the chelating agent of zinc, copper, manganese, boron, molybdenum, nickel, magnesium, cobalt and iron.
The present invention will also protect the application in humic acid preparation Organic pesticide residues field in soil is reduced, including such as
Lower step：
A, by the described humic acid preparation and water for reducing Organic pesticide residues in soil according to（3~5）：300 volume ratio is carried out
Dilution, is obtained humic acid inhibitor dilutions, and the humic acid inhibitor dilutions per hectare farmland usage amount for 200 ~
400L；
B, spray the humic acid inhibitor dilutions in crops breeding time points for 3 times, for the first time for sowing before, be for second growth
Mid-term, for the third time for harvest it is first 10 ~ 12 days.
Preferably, Organic pesticide residues field includes being opened for residues of pesticides soil, lean soil in the reduction soil
Cultivate and be contaminated the integrated disposal processing after soil cleaning.
Preferably, the step of being sprayed using the aqueous solution of humic acid preparation is additionally included in before crop seeding.
Preferably, using standard irrigation solution sprayer unit, the consumption rate used by single treatment per hectare is the dense of 2-3 liters
The sprinkling of contracting liquid/200 liter.
After the humic acid preparation of Organic pesticide residues is applied in organic agricultural chemicals contaminated soil in reduction soil of the invention, lead to
Cross absorption, complexing（Chelating）, the mode such as redox passivation is generated to the organic pollution in soil so that in soil
Organic agricultural chemicals substantially reduced to the migration amount of its aerial part, and then may finally effectively reduced by crop, root system of plant
Organic pesticide residues amount in soil and in crops.The present invention is former based on contaminated soil based on environmental protection and agriculture angle
The principle and humic acid substance of position solidification and stabilization reparation, in the great potential and advantage in soil remediation field, are to solve at present
Certainly Organic pesticide residues problem provides solution in soil.
