Background technology
Coated fertilizer claims again coated fertilizer, film fertilizer.The fertilizer forming with semipermeability or opacity film substrate parcel quick-acting chemical fertilizer granule.Filmogen has plastics, resin, paraffin, polyethylene and elementary sulfur etc.The object of coating is that the available nutrient of coated fertilizer the inside after being manured into soil is discharged lentamente, to extend fertilizer efficiency.Rate of release is decided by coating kind, thickness, particle diameter, fertilizer solvability, the soil moisture, soil moisture content and soil microbial activities etc.Be applicable to that economic worth is high, breeding time is long, fertilizer requirement is large but the crop of inconvenient split application, and nutrient is easy to that the temperature of leaching loss is high, area of heavy rainfull or irrigation region, especially on the light sand loam soil of quality.Existing coated fertilizer lacks specific aim more.
Summary of the invention
The object of the present invention is to provide a kind of with strong points, effective fertilizer special for soybeans.
Above-mentioned purpose realizes by following scheme:
A kind of fertilizer special for soybeans, it is characterized in that: it is to be made through coating process by the raw material of following weight parts: composite coated powder 1-3, wintergreen oil 4-6, paraffin 5-8, urea 20-24, diammonium phosphate 40-50, Repone K 40-50, zinc sulfate 1-2, borax 0.5-1.5, Common Cnidium Fruit 1-2, wilkinite 0.5-1.5; Described composite coated powder is made by the raw material of following weight parts: calcium carbonate 1-2, iron sand 1-2, rhombspar 1-2, potassium felspar sand 1-2, slag 2-4, root of langdu powder 3-5, Folium pterocaryae stenopterae powder 1-2.
Described a kind of fertilizer special for soybeans, it is characterized in that: the preparation method of described composite coated powder is: mix by weight raw material calcium carbonate, iron sand, rhombspar, potassium felspar sand, slag, after after 400-500 ℃ of scaling loss 6-8 hour, common process grinds to form nanometer powder, after mixing by weight with root of langdu powder, Folium pterocaryae stenopterae powder and get final product.
Described a kind of fertilizer special for soybeans, is characterized in that: described wilkinite is nano-bentonite.
Described a kind of fertilizer special for soybeans, is characterized in that:
Preparation method is:
(1) urea, diammonium phosphate, Repone K, zinc sulfate, borax, Common Cnidium Fruit, wilkinite mix rear pulverizing by weight, cross 100-200 mesh sieve, then common process granulation and compound fertilizer granule;
(2) having sprayed by weight the composite coated powder of compound fertilizer granule external parcel of wintergreen oil, obtain coated carbamide one time, spray by weight the paraffin of melting on a coated carbamide surface, obtain product.
Described a kind of fertilizer special for soybeans, is characterized in that:
Preparation method is:
(1) urea, diammonium phosphate, Repone K, zinc sulfate, borax, Common Cnidium Fruit, wilkinite mix rear pulverizing by weight, cross 100-200 mesh sieve, then common process granulation and compound fertilizer granule;
(2) in rotary drum seed-coating machine, put into by weight compound fertilizer granule, preheating 6-8min at 30-40 ℃, seed-coating machine rotating speed is 35-40r/min, after preheating, temperature is remained on to 45-55 ℃, rotating speed remains on 45-55r/min, in rotary drum, spray wintergreen oil, in rotary drum, add composite coated powder simultaneously, after adding by weight composite coated powder and having sprayed wintergreen oil, keep the rotating speed of seed-coating machine at 35-45r/min, control temperature at 40-50 ℃, discharging after 20-24 minute, air-dry, obtain coated fertilizer one time;
(3) coated fertilizer is dropped in rotary drum seed-coating machine again, it is 40-50 r/min that seed-coating machine rotating speed is set, temperature remains on 50-70 ℃, after preheating 30-35min, toward the paraffin that sprays heating and melting in rotary drum, 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:
1, 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.Bentonite nanoization can make slow release effect of the present invention better, in the situation that reaching equal slow release effect, the wilkinite usage quantity of nanometer still less, more environmental protection, root of langdu powder, Fructus Cnidii powder, Folium pterocaryae stenopterae powder can play good sterilization and disinsection effect, and the in the situation that of coating, this effect can be long-acting embodies.
2, the present invention is in preparation, because wintergreen oil and composite coated powder coating layer can produce certain micropore, then sprays paraffin and can effectively extend sustained release performance.
