Auxiliary agent is made up of the raw material of following weight part: poultry feather 12-14, nano-sized carbon 6-8, the sulphuric acid soln 30-40 of 30-40%, trisodium phosphate 1-2, gac fine powder 18-20, Sodium hydroxide q. s, Cuprocitrol 1-2, manganese citrate 1-2, zinc citrate 1-2, preparation method is: first poultry feather is passed through washing, pulverize after high-temperature sterilization, drop in sulphuric acid soln, add nano-sized carbon subsequently, trisodium phosphate, 25-30h is soaked after stirring, appropriate sodium hydroxide neutralization solution pH value is added to 6.5-7.5 in the hydrolyzed solution obtained, and be heated to 50-70 DEG C, add Cuprocitrol, manganese citrate, zinc citrate, stirring reaction 1-2h, finally add gac fine powder, mix rear drying completely, make powder and get final product.

Described aqueous polyurethane emulsion solid content is 30%-55%;

Described a kind of slow-release compound fertilizer promoting soil fertility, its production stage is as follows:

(1) wheat bran, broad bean skin, soya bean oil expression tankage are mixed rear pulverizing, add myo-Inositol hexaphosphate and appropriate water carries out fermentative processing, for subsequent use to material after becoming thoroughly decomposed completely;

(2) mixed with waiting water of weight part by diatomite, grinding 20-30min, makes diatomite slurry, add Prohexadione calcium, ferrous sulfate, Zinc vitriol subsequently, mix and blend 20-30min, stirs and terminates rear mixture and to anhydrate drying, make diatomite coating material;

(3) first agarose, polyglutamic acid are mixed with appropriate 50-70 DEG C of hot deionized water, be stirred to material to dissolve completely, again nano-silicon is mixed with Sodium dodecylbenzene sulfonate (ABS), add in aqueous polyurethane emulsion together with agarose, polyglutamic acid mixed aqueous solution, be heated to 60-80 DEG C, abundant stirring 1-1.5h, makes slow release coating agent for subsequent use;

(4) other leftover materials are mixed with step (1), (2) gained material; drop into granulation in tablets press; and at slow release coating agent prepared by obtained particle surface sprinkling step (3), the particle after coating, through warm air drying, room temperature cooling, gets product.

Beneficial effect of the present invention is: formula Raw wide material sources, take full advantage of raw material common in daily life production, while reduction production cost, reduce the amount of chemical fertilizer, more environment-friendly high-efficiency, improves the single fixing phenomenon of conventional composite fertilizer nutrient; Production technique utilizes diatomite have the nutrient of promoter action to adsorb mutually with Prohexadione calcium, ferrous sulfate, Zinc vitriol etc. to plant growth, realize the coated of nutrient, prevent the invalid release of nutrient and loss; With the urethane slow release coating agent of the modifications such as agarose, polyglutamic acid, nano-silicon, there is excellent coated slow-release controllability, slow release effect persistent high efficiency, can ensure that crop absorbs enough nutrients in growth cycle; Composite fertilizer prepared by the present invention utilizes diatomite and modified polyurethane slow release coating agent to be formed dual coated to nutrient, make fertilizer efficiency more lasting, and containing the organic composition after multiple fermentation, nutrient is more easily absorbed by crops, soil fertility can be promoted, not spoiled soil acid base equilibrium, source improves the growing environment of crop, for crop all obtains considerable raising on yield and quality.
