Description

Pear tree fertilizer of a kind of liquid state fermentation and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, pear tree fertilizer being specifically related to a kind of liquid state fermentation and preparation method thereof.

Background technology

Excrement of animals and the resistates of various organic domestic waste after fermentation are the organic colloids that a kind of size distribution is very wide, and the thorough separation difficulty of its solid-liquid is very large, and this makes fermented liquid be restricted to commercial fertilizer transformation by traditional Land use systems.To the organic waste water of different sources, there is different treatment processs, as the flocculation agent such as Tai-Ace S 150 and active silica, chitin and chitosan, polyacrylamide or flocculation agent are reported a lot to the treatment effect of suspension system, but be the theoretical investigation in laboratory mostly.

Residue after disposed waste in agricultural crop straw, biology and the manure fermentation of livestock is mainly divided into nutritive substance, mineral substance and active substance, nutritive substance is wherein divided into again crude protein, crude fat, humic acid, crude fibre, nitrogen-free extract, mineral substance is divided into again trace element and major element, and activeconstituents is amino acid, plant hormone, vitamin B group, lytic enzyme and microbiotic substantially.Containing abundant nutritive element and organic matter.

Summary of the invention

Be fully utilized to make each composition in fermented ingredient, the present invention uses flocculation agent to be adsorbed by each for fermented ingredient kind of plant beneficiating ingredient, then the fertilizer of different-effect and type is prepared for fertilizer additive, be satisfied with the demand of various Different Crop, not only self provide abundant nutritive ingredient, and can promote that crop is to the absorption of NPK, concrete grammar is as follows:

A kind of pear tree fertilizer of liquid state fermentation, it is characterized in that, be made up of the raw material of following weight part: industrial starch 30 ~ 35, soyabean expeller 25 ~ 35, complex micro organism fungicide 3 ~ 5, wheat bran 45 ~ 60, earthworm soil 15 ~ 20, withered leaf 10 ~ 15, humic acid 6 ~ 8, saturated limewater 12 ~ 18, potassium primary phosphate 10 ~ 16, bicarbonate of ammonia 20 ~ 25, boric acid 8 ~ 12, quartz sand 4 ~ 6, flocculation agent 7 ~ 10 and appropriate water;

Described flocculation agent is made up of the raw material of following weight part: terra alba 15 ~ 20,10% ferrum sulfuricum oxydatum solutum 10 ~ 14,10% acetic acid solution 4 ~ 6, primary isoamyl alcohol 0.6 ~ 1.2, methyl acrylate 6 ~ 8, tween 80 1 ~ 2, peanut oil 3 ~ 5, ethanol 4 ~ 8 and water 60; The mixing of second alcohol and water is poured in reactor by preparation method, then methyl acrylate is added, be heated to 60 ~ 70 DEG C of stirring and dissolving, then add 10% ferrum sulfuricum oxydatum solutum, 10% acetic acid solution, primary isoamyl alcohol and terra alba, keep temperature of reaction kettle, adjustment rotating speed 100 ~ 120r/min stirs 20 ~ 30min, finally add tween 80 and peanut oil simultaneously, insulated and stirred 30min is emulsion uniformly, obtains pulvis by funnel suction filtration, namely obtains pulvis flocculation agent after oven dry.

A preparation method for the pear tree fertilizer of liquid state fermentation, is characterized in that, comprises following step:

(1) mixed industrial starch, soyabean expeller, wheat bran, withered leaf and humic acid, add the water of 4 ~ 5 times of its weight parts, ball milling 30 ~ 45min, to homogenate, pours in fermentor tank, carries out high-temperature sterilization process;

(2) complex microorganism bacterial classification is added the water dilution of 5 times of its weight parts, be modulated into bacterium liquid, be then seeded in the fermentor tank of (1), adjustment pH5.5 ~ 7, temperature 24 ~ 28 DEG C, passes into sterile air simultaneously and stirs, and ferments 5 ~ 7 days;

(3) after (2) complete, pour out fermented liquid and add flocculation agent, spraying saturated limewater after stirring 8 ~ 10min in fermented liquid surface, leave standstill 30 ~ 40min and carry out precipitation adsorption process voluntarily, dry in drier after completing;

(4) by the mixing of the precipitation material described in (3) earthworm soil, potassium primary phosphate, bicarbonate of ammonia, boric acid, quartz sand and other remaining component, pasty state is modulated into, by spray granulating.

Study Tai-Ace S 150, ferric sulfate, iron(ic) chloride, ferrous sulfate by experiment under the effect of saturated limewater to the cohesion of fermented liquid, first stage is mixed with the fermented liquid of excrement of animals a kind of elder generation of four kinds of flocculation agent above, then add saturated limewater and carry out precipitation adsorption, then all the components is transferred in filter bag, with the centrifugal 3 ~ 5min of drier, by for subsequent use for air-dry for gained material rear pulverizing, be the fermented ingredient after cohesion;

Above-mentioned fermented ingredient is added in the ternary compound fertilizer of urea-primary ammonium phosphate-Repone K of 10-10-10 ratio as the additive of Chemical Mixed Fertilizer, for planting common agricultural, agrochemical analytical procedure detects the available nutrient of soil routinely simultaneously, wherein N is 72.4mg/kg, P is 3.4mg/kg, K be 156mg/kg, K is 421mg/kg, organic matter is 18.2g/kg, pH is 5.5.

Compared with un-added chemical fertilizer, Chemical Mixed Fertilizer volume increase 9.5 ~ 11.6% of the present invention, and the mixed organic manure volume increase 14.5% ~ 16.4% of 80% amount of nutrients, can also make the Vc of agricultural-food improve.

In separation test, by being in the test of main component to flocculation agent in 4, prove to adopt ferric sulfate to be the main component of flocculation agent, the flocculating result reached is best, then 10% acetic acid is adopted to have certain promoter action as the separating effect of cohesion medium to inorganic flocculant, but the reaction of acetic acid and fermented liquid is comparatively slow, period, some fermented liquid was overflowed with the bubble of densification, so add primary isoamyl alcohol when preparing flocculation agent as defoamer, adding the minimum terra alba of particle diameter is stablizer, make each composition of ferric sulfate and cohesion promoter action under the cohesive action of methyl acrylate, be adsorbed on the surface of landplaster particle, after all the components has adsorbed, finally adding a certain amount of vegetables oil can effectively prevent flocculation agent particle to be mutually sticked together, become agglomerate, influence effect, particle aggregation agent after completing just can with an overall form storage, transport and use, successful.

Beneficial effect of the present invention: the present invention adopts liquid fermenting formula to ferment, what ferment is more thorough, in the water of the various component dissolves useful to farm crop, recycling special flocculation agent condenses in together, then dries the processing being used for fertilizer, and test proves the absorption that effectively can promote chemical fertilizer NPK, simultaneously through liquid state fermentation, be fermentation speed, efficiency or result is all better than solid state fermentation, the various wastes in life are utilized, realize merchandized handling.
