Abstract

The invention discloses a preparation method of novel blueberry special-purpose fertilizer. According to the preparation method, fermentation is mainly carried out in a fermentation tank and comprises composting chicken manure in the fermentation tank, preferably adding a proper amount of zymophyte into the fermentation tank, covering the fermentation tank with an agricultural mulch film and generally carrying out fermentation for 10-20 days. The deeply fermented chicken manure is dried by an oven and then is crushed, wherein the crushed chicken manure can be directly used as traditional farm manure but is not commercial organic fertilizer. According to the NY525-2002 standard, the crushed chicken manure can be processes into the commercial organic fertilizer. According to the NY525-2002 standard, the commercial organic fertilizer must have total NPK content greater than or equal to 4%, organic matter content greater than or equal to 30%, water content less than or equal to 20% and a pH value of 5.5-8.0. The commercial organic fertilizer must also satisfy requirements such as five heavy metal content below a standard value and roundworm ovum mortality and colititer below standard values. The commercial organic fertilizer satisfying the above requirements is qualified commercial organic fertilizer.

Description

A kind of making method of novel blueberry special fertilizer

Technical field

The invention belongs to the fertilizer field, be specifically related to a kind of making method of novel blueberry special fertilizer.

Background technology

The fowl poultry kind ight soil (comprising barnyard manure) such as pig, chicken, duck.Large-scale Organic Fertilizer Plants, large-scale cultivation factory and farm.Play temperature fast, envrionment temperature is more than 0 ℃ the time, and within 48 hours, temperature rises to more than 55 ℃.Can fully decompose in fowl poultry kind ight soil the organic sulfide that produces stink, organic nitrogen compound etc.After stirring, within 2-3 days, can eliminate stink.The compost cycle is short, within 10-15 days, becomes thoroughly decomposed fully.The compost high-temperature and durable, can kill germ, worm's ovum, weed seed in fermented product., compost total nutrient loss is few, humus content is high, the potassium cellulose content increases obviously.Contain the harmful germ of a large amount of microorganisms in chicken manure, definitely can not directly use, must carry out degree of depth thermophilic fermentation.The purpose of certain fermentation is mainly two, the one, and the kill harmful germ, the one, the material fully do not digested is carried out to organic materialization, increase actual organic content.

Summary of the invention

Main making method:

Fermentation is mainly to carry out in fermentation vat, is about to chicken manure and is deposited in this ferment, adds appropriate fermented bacterium in the time of best, still carries out the film covering with agricultural mulching afterwards, and the time of fermentation is 10-20 days usually.Chicken manure after the degree of depth is sent out this ferment, dried, and pulverizes.Chicken manure after pulverizing can directly be used, but also just is referred to as traditional farm manure, still can not be referred to as Commodity Organic Fertilizer.But, if make commercial organic fertilizer, carry out the NY525-2002 standard.According to this standard, the total content of NPK must be more than or equal to 4%, and organic matter must be more than or equal to 30%, and moisture content is less than or equal to 20%, and pH value is at 5.5-8.0.Certainly also have other requirement, as the content of five heavy metals can not exceed standard, induced worm egg death rate and colititre etc. all needs conformance with standard.Only meeting above-mentioned requirements, is all qualified organic fertilizer.From in appearance, Commodity Organic Fertilizer is divided into powdery and particle two kinds.If be produced into the Commodity Organic Fertilizer of particle, also need to carry out granulation, the granulating production equipment of organic fertilizer generally adopts the many of disc granulation, comprises metering outfit, assay device, whipping device, granulating equipment, drying plant, screening plant, filling apparatus, seam bag equipment.

1, fluff packing method

In the collected manure place, in banking process, keep ventilation good the fresh livestock fecaluria fluff packing of looping.Under hot conditions, the livestock fecaluria becomes thoroughly decomposed and decomposes soon, within short duration, can make the fertilizer become thoroughly decomposed.

2, tightly packed method

From the livestock fecaluria tripped out in enclosing, in the collected manure place, to pile up from level to level, accumulation limit, limit compresses.If too dry, can add suitable quantity of water to keep moistening, the height of fertile heap is advisable with 1.5 meters to 2 meters, waits to pile up complete, with earth, fertilizer is piled and is sealed, and temperature generally remains on 15 ℃ to 35 ℃.Adopt the accumulation of this method soil ulmin more, nitrogen loss is less, approximately through 3 after 4 months, fertilizer can reach the state that partly becomes thoroughly decomposed, and more than 6 months, could become thoroughly decomposed fully.

3, loose tight cross stacking method

Adopt loose closely alternately accumulation, both can shorten becoming thoroughly decomposed the time of fertilizer, can reduce nitrogen loss again.Fresh fertilizer, approximately one meter high of the outer fluff packing of circle, is not compressed, in order to ferment.Generally after 2 days to 3 days in fertile heap temperature can reach 60 ℃ to 70 ℃, also can continue to pile up fresh fertilizer later, pile up, until highly 2 meters to 2.5 meters so from level to level.With earth, the fertilizer heap is sealed, kept temperature, hinder air and enter, prevent that nutriment in a fertilizer loss and moisture from evaporating in a large number.General 1 first quarter moon to 2 month just can reach the state that partly becomes thoroughly decomposed, and after 4 months, just can become thoroughly decomposed fully.

Enzyme agent fertilizer bacterial classification Rw enzyme agent is the high-tech product of development.This product is by multiple bacterial strains such as the fungi that can strongly decompose feces of livestock and poultry, bacterium, thread fungus, yeast and relevant enzymes is composite forms, aerobic fermentation, decomposing protein are very competent, can reach the effect of intensification, deodorizing, elimination disease and pest, weed seed and enrichment nutrient simultaneously.

4, dried poultrymanure fermentation

First dried poultrymanure is laid on the ground to (outdoor concrete floor or soil all can) and is strip, by chicken manure, heavy 35% waters.

Chicken manure per ton spreads 1 kilogram of quick rotting agent (because little being difficult to of quick rotting agent consumption sprinkles evenly, can first add rice bran or wheat bran to make Preblend), adds 15 kilograms of calcium superphosphate (deodorizing is used), adds 100 kilograms, grass meal or careless carbon.Then by compost overturning twice, pile the heap that high approximately 1 meter, wide 1.5-2 rice, length are not limit, and the punching of heap top several.Finally with rectangle plastics cloth, the fertilizer heap is covered, plastic cloth and ground join, and every 1 meter pressure one weight, make not only to ventilate but also avoid being heaved by strong wind in film.In summer, fermentation in autumn, take off 1 time (1-2 hour) of film ventilation sooner or later, can take off at dusk the previous day film if fine, cover morning next day.After stack retting 3-4 days, the heap temperature can rise to 60-70 ℃.But stack retting turning 1 time after 10 days, stack retting 20 days can be well-done, and nutriment in a fertilizer improves, and eliminates harmful entomogenous fungi, becomes good environmental friend fertilizer.

5, wet chicken manure fermenting

First spread on the ground one deck straw powder (rice bran, grass meal, peanut hull meal, the peat composed of rotten mosses all can), then above the chicken manure that will wet is layered on, heavily be sprinkled into 0.1% urea by windrow, by the heavy 15 kilograms of calcium superphosphate that are sprinkled into per ton, be sprinkled into (quick rotting agent is 0.2%, separately adds wheat bran or rice bran pre-mixing) by the Preblend processed of 0.2% quick rotting agent.

The moisture controlled of fertile heap is in 50% left and right, and available straw powder is regulated humidity, agglomerating to hold, freely land to scatter from 1 meter high and be advisable.By compost overturning twice, pile wide 1.5-2 rice, high 1 meter heap that left and right, length are not limit, and, with bludgeoning ventilating pit, cover plastic cloth insulation, moisturizing, fertilizer conservation.Other management, with the dried poultrymanure fermentation, should be specifically noted that ventilation.

Three, precaution

1, this product must with the fermented product rear use that stirs.

2, this product must be deposited in ventilation, cool place, dry place.

Embodiment 1:

First the raw material moisture mixed is controlled to about 40%-50%, then use: the water surface is mixed bacterial classification, is sprinkling upon the fertilizer top layer mixed, and manually equably the raw material stirrer of packing into is carried out to crushing, stirring.Fertilizer stirs its water content of GPRS while pulverizing, and general water content is no more than 40%-45%.Moisture is excessive or too smallly all can affect fermented quality, with hand by fertilizer degree of pinching group, hand seam water breakthrough but do not drip to loose one's grip to land to fall and dare to be advisable.Stir and want evenly, thoroughly, want the fluffy living piece that do not stay.

The batching that is stirred heap or wide 1.5-2 rice, high 0.3-0.4 rice rectangular, upper cover straw screen or mat or hessian cloth carry out aerobic fermentation composting.The temperature in 24 hours of generally banking up rises to 50 ℃, and in 48 hours, temperature can rise to 60-70 ℃, and during fermentation high like this temperature can be killed all pathogeny bacterium and worm's ovum, grass-seed etc.Obtain novel blueberry fertilizer special for organic.
