Described a kind of antibacterial green dual control slow-release compound fertilizer, its production stage is as follows:
(1) by mixing with plant ash, soy sauce residues, yellow wine lees after myrtillin leave pulverizing, add appropriate water, anaerobically fermenting 3-4d under normal temperature condition, fermentation material is for subsequent use;
(2) diatomite is mixed with the water that waits weight part, grind 20-30min, make diatomite slurry, add poly-silicic acid iron sulfate with stirring arm material limit, back, poly-silicic acid iron sulfate adds medical stone powder after adding, and stirs 10-15min, then adds borax, ammonium molybdate, after stirring, mixture anhydrates dryly, makes diatomite coating material;
(3) polyvinyl alcohol, expanded starch, vinylformic acid are mixed and added in appropriate deionized water, be stirred to material and dissolve completely after dispersion, add potassium permanganate, litsea cubeba oil, continue to stir 10-15min, make 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 spraying slow release coating agent prepared by step (3) at the particle surface making, the particle after coating is cooling through warm air drying, room temperature, gets product.
Beneficial effect of the present invention is: formula Raw wide material sources, take full advantage of common raw material in daily life production, and in reducing production costs, improve the single fixing phenomenon of conventional composite fertilizer nutrient; In production technique, utilize the heat and the gas that in medical stone powder and poly-silicic acid iron sulfate process, produce can promote the good nutrition absorption in diatomite and raw material, reach stable covered effect; The slow release coating agent obtaining with mixed raw materials such as polyvinyl alcohol, expanded starch, vinylformic acid, has good coated slow-release controllability, and slow release effect is stable lasting, and wherein coated litsea cubeba oil also has the effect that suppresses pathomycete, bacterium; Composite fertilizer prepared by the present invention utilizes diatomite and slow release coating agent nutrient to be formed dual coated, nutrient is difficult for running off, fertilizer efficiency is more lasting, can meet the each growth period desired nutritional of crop, and for crop root provides good growing environment, the not spoiled soil eubiosis, is a kind of composite fertilizer of novel green high-efficient, can improve significantly crop yield and quality, improve planting benefit.
