Preferably, including following components: 1.2 parts of pesticide active ingredient, 3 parts of auxiliary material, 35 parts of filler material, 15 parts of bonding agent,
20 parts and 8 parts of organic material of water.
Preferably, the pesticide active ingredient be selected from including insecticide, fungicide, acaricide, nematicide, herbicide,
One group in molluscicide and plant growth regulator or multiple combinations.
Preferably, the auxiliary material includes sucrose and cornstarch, and the weight ratio of sucrose and cornstarch is 1:4-7.
Preferably, the filler material include talcum powder, kaolin, bentonite, sawdust, light calcium carbonate powder, calcium carbonate, conch meal,
One or more combinations of diatomite, nacrite, resin, clay powder and gelatinized starch.
Preferably, the bonding agent include Sodium Polyacrylate, carboxymethyl cellulose, polyvinyl alcohol, sodium alginate, hide glue,
Gelatine and the one or more combinations of epoxy glue.
Preferably, the organic material includes poultry manure, straw, sawdust, rice bran, bagasse and peanut shell, wherein
Poultry manure includes one or more combinations of sheep dung, pig manure, horsehit, duck excrement and chicken manure.
A kind of preparation method of slow controlled release granular pesticide, comprising the following steps:
S1, pesticide active ingredient, auxiliary material and filler material mixed first by weight ratio, stirs evenly, is made
The mixed material of standby inner sandwich layer；
S2, mixed material obtained in S1 is first passed through to roller drying processing, is put into pelletizer and is granulated later, obtains inner core
Layer particle；
S3, bonding agent, water and organic material are mixed, are stirred evenly, made mixed slurry in underflow state, obtain mixing slurry
Liquid；
S4, inner sandwich layer particle obtained in S2 is put into mixed serum obtained in S3, does outer layer covers processing, make to mix
Slurries wrap inner sandwich layer particle, obtain jacket layer；
S5, the inner sandwich layer particle with jacket layer will be finally obtained in S4 being put into dryer, drying obtains sustained-release pesticides
Grain.
Preferably, in S5, organic material also needs to carry out heating pulverization process before progress, is in first block through roller machine drying
Shape, then granulate through crusher is broken.
Technical effect and advantage of the invention: the slow controlled release granular pesticide and preparation method thereof, by being provided with inner core
Layer and jacket layer, jacket layer wrap up pesticide active ingredient, delay the pesticide active ingredient in internal inner sandwich layer
Slow release effectively extends the acquisition time of pesticide, avoids and disposably all discharges pesticide active ingredient, causes to waste
The problem of, preparation method is simple and practical, and inner sandwich layer includes filler material and auxiliary material, can be in the mixing with pesticide active ingredient
Cheng Zhong guarantees that pesticide active ingredient can be finally discharged into soil, and the component of jacket layer and inner sandwich layer is mostly organic material
Material can be mixed with soil by biodegrade, not will cause the pollution to environment, while also can be by organic material
Sugarcane sugar and starch reagent in organic principle and auxiliary material can either improve the nutrition composition in soil in pesticide slow release,
After can be improved action of agricultural chemicals again simultaneously, the growing environment of beneficial bacterium.
