The preparation method of the special composite coated fertilizer containing chelating amino acids liquid of described a kind of soybean base fertilizer, is characterized in that: every 80-150g animal feather adopts the sulphuric acid hydrolysis that the concentration of 200-300ml is 25-35%.
The preparation method of the special composite coated fertilizer containing chelating amino acids liquid of described a kind of soybean base fertilizer, it is characterized in that: step (4) operating procedure is: in rotary drum seed-coating machine, put into by weight compound fertilizer granule, preheating 12-15min at 60-70 ℃, the rotating speed of seed-coating machine is at 40-50r/min, toward the paraffin that sprays heating and melting in rotary drum bag, spray by weight after paraffin, cool the temperature to 20-30 ℃, seed-coating machine rotating speed is 35-45r/min, after 12-15 minute, discharging, obtains product after normal temperature cooling drying.
Beneficial effect of the present invention is:
The present invention, by the reasonable re-compounded soybean required each nutritive element of growing, makes compound manure, and light weight, water holding, fertilizer conservation, sustained release performance are outstanding.Kuh-seng has sterilization and disinsection effect, wears into pulvis, sneaks in compound manure, contributes to prevention and elimination of disease and pests.Chelating amino acids liquid mixes micro-, moderate-element wherein, when having increased the nutrition of fertilizer, can allow micro-, moderate-element discharge more slowly.
Paraffin can regulate the slow release effect of coated fertilizer as outer coating agent.Favourable absorption effect by composite powder to chemical fertilizer nutrient, the retardation that soil pore water is permeated delay the release to chemical fertilizer nutrient, have obtained good result, have also enriched the nutritive element of fertilizer simultaneously together with chelating amino acids liquid
