Technical field
The invention belongs to biological organic fertilizer fields, and in particular to a kind of biology using microbial fermentation composition is compounded with
Machine fertilizer.
Background technique
Biological organic fertilizer plays an important role always during China's agricultural development, it is microorganisms with specific functions
With mainly with plant and animal residues (such as feces of livestock and poultry, agricultural crop straw) for source and through harmless treatment, decomposed organic matter
Expect that the one kind being combined has both the fertilizer of microbial manure and organic fertilizer effect.The microorganism of its specific function can be including the use of
The beneficial bacterium that the phosphate solubilizing bacteria and potassium solubilizing bacteria of phosphorus, potassium element in soil or parent soil material can antagonism soil-borne pathogens growth, breed
Deng, so that the organic nutrients such as organic matter rich in, amino acid, protein in organic fertilizer, while also containing nitrogen, phosphorus, potassium etc.
Inorganic nutrients, a large number of studies show that, crop yield, getting fat soil fertility not only can be improved in application biological organic fertilizer, can more improve agriculture
Product quality improves waste utilization rate, economizes on resources, preserve the ecological environment, and is the important of realization Sustainable Development of Modern Agriculture
Approach.
It handles to obtain currently, biological organic fertilizer usually passes through compost fermentation.Compost is in items such as certain moisture, C/N ratios
It is suitable for the process of the fertilizer of land use under part, by the effect of microorganism by organic matter degradation and generating, with aerobic compost
Based on.The composting process of modernization would generally experienced three stages, respectively in thermophase (phase temperature is usually 30-40
DEG C, the time is mostly 1-3 day), hot stage (for the phase temperature usually at 45-65 DEG C, the time is mostly 3-8 days), cooling and it is decomposed
Stage (time is usually 10-20 days).Wherein, hot stage is dirty for promoting crops stalk, human and animal excreta, weeds, rubbish
The decomposed and mock-strawberry germ therein of the deposits such as mud and worm's ovum etc. have good effect, but the stage wants temperature
It asks higher, and the duration is longer, not only needs large area place, but also the stink issued is heavier, it is raw to influence the mankind around
Living, oxygen demand is also big, and capital expenditure is more, in addition, serious to soil fail at compost.
Summary of the invention
It is asked the purpose of the present invention is serious, serious to soil fail for stink in composting process of the existing technology
Topic provides a kind of preparation process and does not allow the biological compound organic fertilizer for being also easy to produce stench and will not destroying soil.
