Description
Technical field
The invention belongs to agricultural plantation technology fields, and in particular to a kind of preparation method of environment-friendly pesticide.
Background technology
Pesticide can be used for killing the biology of insect, fungi and the growth of other damages to crops.The pesticide used earliest has drop
DDT, six six six etc., they can largely eliminate pest.But their stability is good, can long-term existence in the environment, and planted dynamic
It constantly accumulates in object and human body, is eliminated thus.It used organophosphorus pesticide, such as DDVP instead later, and substituted initial pesticide.So
And they contain P elements, be easy to cause aquatic organism eutrophication.
Chinese patent CN104472480A discloses a kind of composition of degrading pesticide residues, and active constituent is by following heavy
The group of amount part is grouped as：1 part of algal polysaccharides, 0.05~20 part of rare earth：0.05~20 part of gibberellic acid.Degrading pesticide residues of the present invention
Composition can stablize under the premise of not influencing pesticide efficacy, the agriculture in crop products before harvest is greatly reduced
Medicine residual quantity, and surface of agricultural products pesticide residue can be removed and reduce the residual quantity that agricultural product include pesticide, in guarantee
The food security of city's crop products；And be prepared using convenient source, preparation method is simple, of low cost.
Chinese patent CN104342161A discloses a kind of degradating agent for residual agricultural chemicals, it is characterised in that：It contains following group
Point, 8 parts of butene dioic acid, 15 parts of butene dioic acid, 12 parts of alkyl benzene sulphonate, 15 parts of sodium carbonate, 10 parts of sodium sulphate, 56 parts of water, paddy Guang
5 parts of sweet peptide, 1 part of borax, 4 parts of calcium sulfate.The degradation agent further includes 6 parts of benzyl ring.The degradation agent further includes amino acid 18
Part.The degradating agent for residual agricultural chemicals of the invention can effectively improve soil, after the invention degradating agent for residual agricultural chemicals, on the one hand
Beneficial microbe in disinfectant generates a large amount of secondary metabolite in crop root mass propagation in reproductive process,
The formation of soil aggregate structure can thus be promoted.
Existing agricultural chemical insecticide is not degradable, or addition degradation of pesticide agent is needed to degrade pesticide residue, from
And cost is higher, and people often do not reprocess after applying pesticides, and pesticide is caused constantly to remain accumulation.
