Description

A kind of method of utilizing animal manure fermentative production organic composite fertilizer
Technical field
The present invention relates to a kind of method of utilizing animal manure fermentative production organic composite fertilizer, belong to biological utilization of new energy resources field.
Background technology
Organic fertilizer has been applied for many years in agricultural, particularly in rural area, has a large amount of various vegeto-animal wastes, can pile up on the spot, and fermentation, uses on the spot, and source is wide, economical and practical, of a great variety.At China's general using straw, people and animals' fecaluria, or utilize the crop of special plantation as green manure, also utilize river silt, bone meal, plant ash etc.Organic fertilizer is different from chemical fertilizer, they contain complex element, wherein not only there are nitrogen, phosphorus, three kinds of principal elements of potassium, but also contain calcium, magnesium and crop required with its trace element, the nutrient that organic fertilizer contains is organic form more, it must could utilization absorbed by crops through microbial transformation, thereby the slightly slow but reserve strength foot of fertilizer efficiency.Organic fertilizer, in the decomposition and inversion process by microorganism, can partly form soil ulmin, and this humic mass-energy promotes the formation of soil aggregate, thereby can improve the physical properties of soil, strengthens the shock-absorbing capacity of soil.Therefore organic fertilizer is the good fertilizer of getting fat soil fertility, while certainly cooperating use with chemical fertilizer as required, when more effective.
Animal manure is the waste of aquaculture, also very low in agricultural-food utilization ratio.The starter of selling in the market, is that to take milk-acid bacteria be main microbial inoculum mostly, with its fermentation, only can preserve fermentation, and a large amount of fibrous substances that can not degrade in ight soil, can not improve the content of its protein.Therefore the forming technique that, lacks animal manure fermentative production compoiste fertilizer in prior art.
Summary of the invention
The present invention is directed to existing problems, its object is to provide a kind of method of utilizing animal manure fermentative production organic composite fertilizer, utilize the silage principle of anaerobically fermenting, by adding EM bacterium liquid fermentation process, carry out animal manure fermentation, in fertilizer, useful active bacterium composition and survival rate are high, for agricultural provides a kind of nuisanceless high-quality biological organic complex fertilizer; Can not only provide sufficient balanced nutrition to farm crop, and can also rely on the powerful fermentation capacity of decomposition of ferment flora, successive elimination chemical fertilizer, agricultural chemicals are for the pollution of soil, product, transformation soil, reach green, organic standard, the composition that contains living microorganism flora wherein can continue for a long time to play a role in soil, thereby plays increasing both production and income, improves the effect of quality.Technical scheme of the present invention is: a kind of method of utilizing animal manure fermentative production organic composite fertilizer, and the method comprises pretreatment, expanded, batching, fermentation and granulation, it is characterized in that production technique is:
