Described a kind of water conservation long-acting slow-release compound fertilizers containing catnip, its production stage is as follows:

(1) by corn citric acid waste, discarded mushroom root, reed stems and leaves co-grinding, add subsequently appropriate water to carry out fermentative processing, standby after becoming thoroughly decomposed completely;

(2) diatomite is mixed with waiting water of weight part, grinding 20-30min, makes diatomite slurry, the careless dry powder that camphorates subsequently, four water manganous sulfates, ferrous sulfate, and after stirring, mixture anhydrates dryly, makes diatomite coating material;

(3) yam starch is mixed with the deionized water of 6-8 weight part, heating in water bath is to 60-80 ℃, stir gelatinization 20-30min, subsequently the yam starch gelatinization liquid of preparation and vinylformic acid, tween 80, dimethyl silicone oil are added in appropriate water, stir 20-30min, add sodium bicarbonate, ammonium persulphate, continue stirring reaction 40-60min, make slow release coating agent standby;

(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, when reducing production costs, avoid the destruction of a large amount of chemical feedstockss to soil, improved the single fixing phenomenon of conventional composite fertilizer nutrient; In production technique, utilize the raw material that diatomite and camphor grass meal, four water manganous sulfates, ferrous sulfate etc. contain the necessary middle trace element of plant growth and energy cover crop root to adsorb mutually, reach covered effect, prevent the too early invalid loss of raw material; The slow release coating agent of preparing with raw material hybrid reactions such as yam starch gelatinization liquid and vinylformic acid, has good coated slow-release controllability and certain water suction drought-resistant ability; It is dual coated that composite fertilizer prepared by the present invention utilizes diatomite and slow release coating agent to form nutrient, improves the utilization ratio of fertilizer, and have water conservation drought-resistant ability concurrently, can also prevent that worm ant from destroying crop root, can effectively improve output and the quality of crop.
