(4) at 100 weight part compound fertilizer granule surface sprinkling 8-10 weight part melt paraffin coatings, promptly get product.
The special use of described a kind of rape base fertilizer contains the preparation method of the composite coated fertilizer of chelating amino acids liquid, it is characterized in that: described binding liquid refers to a kind of in water glass, benzene emulsion, acrylate and vinyl acetate emulsion, resol, polyvinyl acetate emulsion and the rosin.
The special use of described a kind of rape base fertilizer contains the preparation method of the composite coated fertilizer of chelating amino acids liquid, it is characterized in that: described hydrolyzed solution proportion is 1.1-1.3g/ml.
The special use of described a kind of rape base fertilizer contains the preparation method of the composite coated fertilizer of chelating amino acids liquid, it is characterized in that: it is the sulphuric acid hydrolysis of 25-35% that every 200-250g animal feather adopts the concentration of 200-300ml.
The special use of described a kind of rape base fertilizer contains the preparation method of the composite coated fertilizer of chelating amino acids liquid, it is characterized in that: step (4) operating procedure is: in rotary drum dressing machine, put into compound fertilizer granule by weight, 60-70 ℃ of following preheating 12-15min; The rotating speed of dressing machine is at 40-50r/min; Spray the paraffin of heating and melting in the rotary drum bag, sprayed paraffin by weight after, cool the temperature to 20-30 ℃; Dressing machine rotating speed is 35-45r/min; After 12-15 minute, discharging promptly gets product behind the normal temperature cooling drying.
Beneficial effect of the present invention is:
The present invention makes compound manure through each required nutritive element of reasonable composite growth of rape, and light weight, water holding, the guarantor is fertile, sustained release performance is outstanding.Schizonepeta has the sterilization and disinsection effect, wears into pulvis, sneaks in the compound manure, helps prevention and elimination of disease and pests.Chelating amino acids liquid mixes little, moderate-element wherein, when having increased the nutrition of fertilizer, can let little, moderate-element discharge more slowly.
Paraffin can be regulated the slow release effect of coated fertilizer as outer coating agent.Through composite powder the favourable absorption effect of chemical fertilizer nutrient, the retardation that soil pore water is permeated are delayed the release to chemical fertilizer nutrient, obtained good result, also enriched the nutritive element of fertilizer simultaneously with chelating amino acids liquid.
