(2) by weight, spray the composite coated powder of compound fertilizer granule external parcel of wintergreen oil, obtained coated carbamide one time, on a coated carbamide surface, sprayed by weight the paraffin of melting, obtained product.
Described a kind of spring maize dedicated fertilizer, is characterized in that:
Preparation method is:
(1) urea, diammonium phosphate, Repone K, zinc sulfate, cloves powder, Stemona Root, attapulgite 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 10-12 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, sprayed 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 each required nutritive element of reasonable composite Spring-maize Growth, makes compound manure, and light weight, water holding, fertilizer conservation, sustained release performance are outstanding.Attapulgite clay nanoization can be so that slow release effect of the present invention be better, in the situation that reaching equal slow release effect, the attapulgite usage quantity of nanometer still less, more environmental protection, cloves powder, Leaf of Camphortree 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.
