Abstract
The present invention provides a kind of degradating agent for residual agricultural chemicals, raw material components include potassium permanganate, potassium dihydrogen phosphate, bodied ferric sulfate, nano silica and water.The present invention also provides application of the degradating agent for residual agricultural chemicals in degradation crop remains of pesticide.The degradating agent for residual agricultural chemicals is 63.8~100% to the degradation rate of remains of pesticide, degradation efficiency with higher.Tobacco degradation of pesticide agent provided by the invention is to methyl phenyl ethers anisole, imidacloprid, Acetamiprid, dinotefuran, the Diacloden applied on the crops such as tobacco, oxime grass ester, Tebuconazole, Nitenpyram and olefin conversion have preferable degradation effect, especially significant to Nitenpyram and imidacloprid degradation.
Description
Technical field
The invention belongs to disinfectant fields, and in particular to a kind of degradating agent for residual agricultural chemicals and its preparation method and application.
Background technique
The pesticide being often used in China's cured tobacco production mainly has insecticide, fungicide, nematicide, herbicide and growth to adjust
Agent etc. is saved, a large amount of and long-time service chemical pesticide causes the remaining increase of pesticide in tobacco leaf, while the drug resistance enhancing of disease pest
The factors such as wildness once again have seriously affected the safety of cigarette product and the sustainable development of tobacco agriculture, therefore, exploitation or
Selecting efficient degradation of pesticide product seems particularly significant, and has weight to the sustainable development of modern tobacco agriculture and industry
Want meaning.
Currently, the degradation agent for eliminating pesticide residue is usually to be used to eliminate pesticide residue in soil, specifically it is to provide one kind
Effective degradation agent improves soil texture with being effective, and makes beneficial microbe in crop root mass propagation, and a large amount of numerous
Secondary metabolite is generated during growing, soil granular is promoted to be formed, and so that soil is become loose ventilation, water conservation, fertilizer conservation, such as public
The number of opening is that the Chinese patent of CN104342161 discloses the side of the degradation of pesticide agent using preparations such as enedioic acid and alkyl benzene sulphonates
Case has the function that promote plant growth by improving soil texture, but whether the degradation agent can degrade there is no open
Remaining pesticide on crop.In addition, the prior art also disclose it is residual using the pesticide of the mixtures such as Chinese medicine composition and inorganic salts
Degradation agent, such as the Chinese patent of Publication No. CN104312770 is stayed to disclose using wild chrysanthemum, the same hydrogen-oxygen of great burdock achene Chinese medicine
The technical solution for changing the degradating agent for residual agricultural chemicals of the inorganic salts such as calcium preparation, decomposes the pesticide on crop, dissolves.Although above-mentioned system
Standby degradating agent for residual agricultural chemicals achievees the effect that pesticide decomposes, but at high cost, and does not have and promote plant growth and raising agriculture
The effect of product quality.
Summary of the invention
In view of this, keeping the degradation agent residual to pesticide the purpose of the present invention is to provide a kind of degradating agent for residual agricultural chemicals
There are degradations more thoroughly, while purification sprays water quality, increase the tobacco leaf absorbability of the nutrients such as potassium, phosphorus, iron, and then promote
Into plant growth and quality-improving.
In order to achieve the above-mentioned object of the invention, the present invention the following technical schemes are provided:
The present invention provides a kind of degradating agent for residual agricultural chemicals, raw material components include potassium permanganate, potassium dihydrogen phosphate, polymerised sulphur
Sour iron, nano silica and water.
Preferably, the mass ratio of the potassium permanganate, potassium dihydrogen phosphate, bodied ferric sulfate and nano silica is 1:(2
~5): (0.8~1.3): (0.1~0.5).
Preferably, the degradation agent includes the component of following mass concentration: 0.1~0.5% potassium permanganate, 0.5~
1.0% potassium dihydrogen phosphate, 0.1~0.5% bodied ferric sulfate, 0.05~0.25% nano silica, are supplemented to water
100%.
Preferably, the component including following mass concentration: 0.3% potassium permanganate, 0.8% potassium dihydrogen phosphate, 0.2% polymerization
Ferric sulfate and 0.1% nano silica, are supplemented to 100% with water.
The present invention also provides application of the degradating agent for residual agricultural chemicals in degradation crop remains of pesticide.
Preferably, the crop includes tobacco, leaf vegetables crop and fruit tree.
Preferably, the pesticide includes organic phosphorus, organo-chlorine pesticide.
Preferably, the organic agricultural chemicals is methyl phenyl ethers anisole, imidacloprid, Acetamiprid, dinotefuran, match worm piperazine, oxime grass ester, penta azoles
One or more of alcohol, Nitenpyram and olefin conversion.
Preferably, the application specifically: to crop applying degradating agent for residual agricultural chemicals 2~3 times, every 5~7d of minor tick.
Preferably, when the degradating agent for residual agricultural chemicals is aqua, the dosage sprayed is 30~70L/ mus.
The present invention provides a kind of degradating agent for residual agricultural chemicals, raw material components include potassium permanganate, potassium dihydrogen phosphate, polymerised sulphur
Sour iron, nano silica and water.Using potassium permanganate as parent, it is suitably added potassium dihydrogen phosphate as tobacco leaf nutritive agent,
Potassium dihydrogen phosphate has significant increasing both production and income, improves many excellent works such as potassium content optimization quality, disease and insect resistance, prevention and treatment early ageing
With, and have overcome plant growth later period root system aging absorbability decline caused by malnourished effect；Add simultaneously
Enter bodied ferric sulfate, as the inorganic polymer flocculant of superior performance, on the one hand can purify water, on the other hand can mention
Active principle is risen in the adhesion property on blade face.And nano silica can increase three kinds of substances in leaf as surfactant
The storage in face increases potassium permanganate to the oxidation effectiveness of pesticide residue, while the tobacco leaf for increasing the nutrients such as potassium, phosphorus, iron absorbs energy
Power improves quality of tobacco.By the way that potassium permanganate, potassium dihydrogen phosphate, bodied ferric sulfate, nano silica and water are acted synergistically
Play the role of remains of pesticide on degradation crop.
The application of the degradating agent for residual agricultural chemicals of the invention in degradation crop remains of pesticide.The pesticide residue drop
Solving agent is 63.8~95% to remains of pesticide volume degradation rate, degradation efficiency with higher.
Further, tobacco degradation of pesticide agent provided by the invention is to tobacco virus methyl phenyl ethers anisole, imidacloprid, Acetamiprid, furan
Worm amine, match worm piperazine, oxime grass ester, Tebuconazole, Nitenpyram and olefin conversion have preferable degradation effect, especially to Nitenpyram and pyrrole
Worm quinoline degradation is significant.
