Summary of the invention

Main making method:

Take straw powder, wheat bran as raw material, be equipped with ammonium sulfate and water, autoclave sterilization, the inoculation liquid spawn changes aseptic solid fermentation Quchi over to, thick layer ventilation fermentation preparation trichoderma conidium fermenting culture; With the trichoderma conidium culture, oven dry is pulverized, and adds conidial protective material, and get final product.The present invention is mould as bacterial strain with wood take efficient biological and ecological methods to prevent plant disease, pests, and erosion, utilize the cheap raw materials such as stalk, wheat bran, under the aseptic condition of approximate GMP, fermentative production trichoderma conidium preparation as the soil microorganisms microbial inoculum, is used and is prevented and treated the various plants soil-borne disease, simultaneously, this microbial inoculum can Promoting plant growth, improves utilization rate of fertilizer, and inducing plant produces the ability of degeneration-resistant border and disease resistance.Fermentation mainly is to carry out in fermentation vat, is about to chicken manure and is deposited in this ferment, adds an amount of fermented bacterium in the time of best, still carries out film with agricultural mulching afterwards and covers, and the time of fermentation is 10-20 days usually.The process degree of depth is sent out the chicken manure behind this ferment, dries, and pulverizes.Chicken manure after the 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, namely 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, can not exceed standard such as the content of five heavy metals, induced worm egg death rate and colititre etc. all needs conformance with standard.Only meeting above-mentioned requirements, all is qualified organic fertilizer.From in appearance, Commodity Organic Fertilizer is divided into powdery and particle two kinds.If produce 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.

In the collected manure place, keep ventilation good in the banking process 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 that becomes thoroughly decomposed.The livestock fecaluria that trips out in enclose is piled up from level to level in the collected manure place, the compression while piling up.If too dried, can add suitable quantity of water keeping 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 to be sealed, and temperature generally remains on 15 ℃ to 35 ℃.Adopt the accumulation of this method soil ulmin more, nitrogen loss is less, and approximately fertilizer can reach the state that partly becomes thoroughly decomposed after 4 months through 3, could become thoroughly decomposed fully more than 6 months.Adopt loose closely alternately accumulation, both can shorten becoming thoroughly decomposed the time of fertilizer, can reduce nitrogen loss again.Fresh fertilizer about one meter high of the outer fluff packing of circle, is not compressed, in order to ferment.Temperature can reach 60 ℃ to 70 ℃ in generally fertilizer was piled after 2 days to 3 days, also can continue later on to pile up fresh fertilizer, piled 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 just can become thoroughly decomposed fully after 4 months.

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.
