Described a kind of treated starch ether coating long-acting slow-release compound fertilizers, its production stage is as follows:
(1) potato pulp, cottonseed meal, brewer's grains are mixed to rear pulverizing, add appropriate water by fermentation to becoming thoroughly decomposed completely, fermentation material is standby;
(2) diatomite is mixed with waiting water of weight part, grinding 20-30min, makes diatomite slurry, adds subsequently boron fertilizer, plant ash, stirs rear mixture and anhydrates dryly, makes diatomite coating material;
(3) first titanium dioxide and Witco 1298 Soft Acid mix and blend are disperseed to 30-40min, make modified titanium slurry standby, again starch ethers is mixed with appropriate deionized water, being stirred to starch ethers dissolves after dispersion completely, add modified titanium slurry, polypropylene fibre, high-speed stirring is disperseed 1-2h, makes slow release coating agent standby;
(4) other leftover materials are mixed with step (1), (2) gained material; drop into granulation in tablets press; and the slow release coating agent of preparing in the particle surface spraying step (3) 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, the introducing of a large amount of organic matter materials, has not only reduced growth cost, improve the single fixing phenomenon of conventional composite fertilizer nutrient, also effectively protected soil; In production technique, utilize diatomite and boron fertilizer, plant ash etc. to contain the raw material that plant growth must nutrient and adsorb mutually, thereby effectively prevent that nutrient runs off too early; The slow release coating agent of preparing with the starch ethers solution of the material modifications such as polypropylene fibre, titanium dioxide, has good coated slow-release controllability, and fertile amount is evenly lasting thoroughly; Composite fertilizer prepared by the present invention utilizes slow release coating agent prepared by diatomite and treated starch ether nutrient to be formed dual coated, make the utilization ratio of fertilizer higher, fertilizer efficiency is more lasting, and spoiled soil environment not, has directly improved efficiently Crop yield and quality.
