Technical field

The present invention relates to compound manure field, be specifically related to the short long coated slow-release compound manure of a kind of improvement soil.

Background technology

In modern agricultural production, the figure of the composite fertilizer that is seen everywhere, it has, and nutrient content is high, minor component is few, utilization rate of fertilizer is high, the advantages such as convenient are used in storage, is promoting to play the part of important role aspect higher yield of crops stable yields.Slow-release compound fertilizer is a kind of important classification in composite fertilizer, the research emphasis of Ye Shi China Growth of Chemical Fertilizer Industry, its slowly-releasing principle is the hydrophobic substance at the coated thin layer in fertiliser granulates surface, thereby inner nutrient is discharged in soil slowly, constantly supply with nutrient to farm crop, effectively raise the utilization ratio of fertilizer.But also there is certain shortcoming in existing slow-release compound fertilizer, be mainly manifested in nutrients ratio relatively fixing, be difficult to meet the different demands of all kinds of soil and all kinds of crops; Slow release effect is not fully up to expectations, does not mate, thereby reduced fertilizer efficiency with crop growth demand, affects plant growth, causes the underproduction reduction of income.

Summary of the invention

The object of the invention is to provide the slow-release compound fertilizer of a kind of low cost, efficient, environmental protection, and to achieve these goals, the technical solution used in the present invention is as follows:

The short long coated slow-release compound manure of a kind of improvement soil, it is characterized in that, this fertilizer is made up of the raw material of following weight part: 1250-2000 order diatomite 10-15, fowl and animal excrement 15-18 becomes thoroughly decomposed, zinc sulfate 2-4, ammonium nitrate 12-15, potassium humate 6-8, calcium sulfate 5-8, magnesium sulfate 3-5, ferrous sulfate 2-3, trypterygine water extraction 6-8, cereuisiae fermentum 2-5, southern magnolia fallen leaves 4-5, wheat bran 10-12, prairie milk vetch herb 5-7, snail shell powder 1-2, trimethyl-glycine 1-3, pigeon dung 4-6, urea 20-22, zein 14-16, polyvinyl butyral acetal 4-5, 90% aqueous ethanolic solution is appropriate, oleic acid 2-3, glyceryl monostearate 1-3, auxiliary agent 4-5,

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 is appropriate, Cuprocitrol 1-2, manganese citrate 1-2, zinc citrate 1-2, preparation method is: first by the washing of poultry feather process, after high-temperature sterilization, pulverize, drop in sulphuric acid soln, add subsequently nano-sized carbon, trisodium phosphate, after stirring, soak 25-30h, in the hydrolyzed solution obtaining, add appropriate sodium hydroxide neutralization solution pH value to 6.5-7.5, 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 dry completely, make powder and get final product.

The described short long coated slow-release compound manure of one improvement soil, its production stage is as follows:

(1) by after cereuisiae fermentum, southern magnolia fallen leaves, wheat bran, prairie milk vetch herb co-grinding, add appropriate water, carry out fermentative processing, for subsequent use after becoming thoroughly decomposed completely;

(2) pigeon dung is after sterilization is processed, and dry, grinding powder is for subsequent use;

(3) diatomite is mixed with waiting the water of weight part, grinding 20-30min, makes diatomite slurry, adds subsequently trypterygine aqueous extract, zinc sulfate, ferrous sulfate, trimethyl-glycine, and after stirring completely, mixture anhydrates dryly, makes diatomite coating material;

(4) zein is added in 90% appropriate aqueous ethanolic solution, heating in water bath, to 50-60 DEG C, is stirred to material and dissolves completely after dispersion, adds polyvinyl butyral acetal, oleic acid, glyceryl monostearate, continue high-speed stirring and mix 2-3h, make slow release coating agent for subsequent use;

(5) other leftover materials are mixed with step (1), (2), (3) gained material; drop into granulation in tablets press; and spraying slow release coating agent prepared by step (4) 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 not only reduce production cost, also improved the single fixing phenomenon of conventional composite fertilizer nutrient simultaneously; In production technique, utilize diatomite and trypterygine aqueous extract, zinc sulfate, ferrous sulfate, trimethyl-glycine etc. to have and regulate the nutrient such as activeconstituents and middle trace element of promoter action to adsorb plant growth, realize better and being coated, prevent nutrient loss; With standby modified corn prolamine slow release coating agents of mixed raw material such as zein, polyvinyl butyral acetal, oleic acid, there is good elasticity and snappiness, film forming ability is strong, Controlled release ability is good, sustained release nutrient for a long time, and finally can be degradable, nontoxic; 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 spoiled soil environment, also contain natural soil improvement composition, strengthen soil vitality, reduce pathogenic bacterium, final significant crop yield and the quality of improving, obtains good planting benefit.
