Description
Technical field
The present invention relates to technical field of pesticide preparations, and in particular to a kind of compound controlled release fertilizer granules of graphene and its system
Preparation Method.
Background technique
Medicine fertilizer be pesticide and fertilizer are formulated according to a certain percentage to mix, and by certain technology by fertilizer and
Pesticide is stable in specific compound system and the novel ecological compound fertilizer of formation, generally makees the carrier of pesticide with fertilizer.Medicine
Fertilizer has both the effective component of pesticide and fertilizer, and applied once had not only been able to satisfy crop to the needs of N,P,K fertilizers, but also can
The pest for endangering plant is killed, thus, it can be achieved that two operating procedures in field are combined into one, this not only saves labour
Power, and reduce the consumption of time and the energy.
In medicine fertilizer system, the raw medicine of pesticide generally cannot be used directly, it is necessary to which processing is configured to various types of preparations,
It can use.At present using the use of earliest, maximum dosage being pulvis, since it can directly spread fertilizer over the fields or mix native use, work efficiency is high,
It without water, is used particularly suitable for the mountain area of drought and water shortage or upper level and forest land, but the disadvantage of pulvis is that easy drift is dirty
Environment is contaminated, pesticide efficacy is low, and general only 20% pulvis is deposited on target organism, and in addition blade face adhesion is poor,
It is easily blown off or by rain drop erosion, and the drug effect phase is shorter.Therefore since the 1970s, the production of pulvis and make
With on a declining curve.Instead granule.Granule is maintaining the advantage that pulvis is easy to use, work efficiency is high, and gram
The low disadvantage of the easy drift pollution environment of pulvis, effective rate of utilization is taken.
But this kind of granule release time is short, Free up Memory is uncontrollable, it is therefore desirable to a kind of with slow releasing function
Granula, burst size, release time and Free up Memory are controllable, and by effective component according to preset concentration and time
(needing to formulate according to the prevention and control of plant diseases, pest control) continues and is slowly released into environment, and can maintain for a long time one it is specific
Concentration.
A kind of Bactericide fertilizer granule containing Fluoxastrobin is disclosed in license notification number CN102674956B, it is this
Granule is using fertilizer as carrier, by the mixing granulations such as Fluoxastrobin and carrier, filler, corrosion inhibiter and binder, obtains having and remove
The particle of bacterium and fertilizer efficiency, still, the essence of this medicine fertilizer particle are no different with the effect separately applied, only have certain sustained release
The incubation period of drug effect and fertilizer efficiency can be appropriately extended in effect, be extremely difficult to answer the controlled-release function of medicine fertilizer efficiency energy in technical effect
It is poor with effect.
License notification number CN104151088B disclose a kind of medicine fertilizer slow-release preparation, and preparation method thereof and application side
Pesticide imidacloprid, bacteria remover fludioxonil and compound fertilizer are mixed with patent medicine fertilizer particle by method, the technical solution, have fertilizer efficiency
The preferable feature of foot, desinsection bacteria-eliminating efficacy, but because similar with the preparation method of previous public technology scheme, at controlled release
Reason aspect still remains deficiency.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of compound controlled release fertilizer granules of graphene and its
Preparation method, the type fertilizer granules are handled by special film-coating technique, have fertilizer efficiency fast and stable, and desinsection drug effect is slowly held
