A kind of preparation method of microbial organic fertilizer
Technical field
The present invention relates to Crop fertilizer preparation field, particularly relate to a kind of preparation method of microbial organic fertilizer.
Background technology
In recent years, because chemical fertilizer and the unreasonable in a large number of chemical pesticide are used, not only consume resource non-renewable in a large number, and destroy Soil structure, pollute quality of agricultural product and environment, have impact on the health existence of the mankind.Therefore, viewed from the green agriculture advocated from modern agricultural production, the development trend of the ecological agriculture, harmless boilogical fertilizer free from environmental pollution, will play a significant role in the future of agriculture is produced.
Biological chemical fertilizer is both containing nutritive element needed for crop, the goods again containing microorganism, be biological, organic and inorganic combination it can replace chemical fertilizer, all kinds of nutritive elements needed for crop growthing development are provided.
But add single culture due to most in microorganism chemical fertilizer, make the nutrition of chemical fertilizer play not exclusively, cause wastage of material, the number of microorganism beneficial bacterium kind survival is simultaneously not high, can not Reusability.
Summary of the invention
Improving microorganism beneficial bacterium kind survival number to solve in background technology, making the fertilizer prepared urge plant growth growth problem, the invention provides a kind of preparation method of microbial organic fertilizer.
Technical scheme provided by the invention is:
A preparation method for microbial organic fertilizer, is characterized in that, comprises the following steps:
1) milk-acid bacteria, bifidus bacillus, actinomycetes and water are put in vessel according to the ratio that mass percent is 1: 1: 1: 3, drip acid, the PH of solution is adjusted to 3-5, under the water vapor atmosphere of 60-70 DEG C, carries out sealing and fermenting, fermentation time is 2-3 hour, obtains mixed fermentation liquid 1;
2) in diatomite, add glutaraldehyde, bis-diazotized benzidine, stir after heating 35-40 DEG C, static 24-48 hour, add mixed fermentation liquid 1, under the water vapor atmosphere of 55-60 DEG C, carry out sealing 1-2 hour, then as ambient temperature curing 12-24 hour, obtain material 1;
3) by step 2) in material 1 to be crushed to particle diameter be 5-10mm, add farm manure and mix, obtain material 2;
4) stack retting: corrugate, layer overlay wall to wall on ditch, by step 3) material 2 that obtains is placed on wall to wall, and spray lime and water, seal stack retting with coverture.
Preferably, the preparation method of described microbial organic fertilizer, is characterized in that, described milk-acid bacteria comprises streptococcus, genus bifidobacterium, genus lactobacillus acidophilus or lactococcus, and this milk-acid bacteria can be wherein one or more.
Preferably, the preparation method of described microbial organic fertilizer, is characterized in that, described farm manure can be one or more of poultry manure, animal waste and human faecal mass.
Preferably, the preparation method of described microbial organic fertilizer, is characterized in that, step 2) in the mass percent of diatomite, glutaraldehyde and bis-diazotized benzidine that adds be 50: 1: 2.
Preferably, the preparation method of described microbial organic fertilizer, is characterized in that, described step 4) in wall to wall be straw or crop material.
Preferably, the preparation method of described microbial organic fertilizer, is characterized in that, described step 4) in stack retting humid control at 50-60%, stack retting temperature is 60-70 DEG C.
Beneficial effect of the present invention:
1, the microbial organic fertilizer prepared contains multiple beneficial flora, by milk-acid bacteria, bifidus bacillus and actinomycetic associating, plays synergy, effectively decomposes the organism in farm manure and degraded cellulose, improves the transformation efficiency of fertilizer.
2, the microbial fertilizer of united symbiosis, can increase Nitrogen In Soils usually source, makes the phosphorus of indissoluble in soil and potassium decompose out, promotes plant absorption; Produce plant hormone material, stimulate and regulate the growth of crop.
3, composite bacteria produces antagonistic action, limits the growth and breeding chance of other pathogenic micro-organism, alleviates insect pest.
4, improve the resistance of crop, bacterial classification induction crop produces free radical dismutase, eliminates because the free radical of adverse circumstance generation is to improve the resistance of crop while alleviating disease.
Save energy, nontoxic, reduce production cost
5, add diatomite in profitable strain and glutaraldehyde, bis-diazotized benzidine carry out crosslinking reaction, make the cell fixation in flora, maintain microbic activity, improve probiotics survival number.
Embodiment
Following examples further illustrate of the present invention, but absolutely not limit the scope of the present invention.Elaborate the present invention further referring to embodiment, but it will be appreciated by those skilled in the art that the present invention is not limited to the preparation method of these embodiments and use.And those skilled in the art can carry out equivalent replacement, combination, improvement to the present invention according to description of the invention or modify, and these all comprise within the scope of the invention.
Embodiment 1

2) in diatomite, glutaraldehyde, bis-diazotized benzidine is added, wherein mass percent is 50: 1: 2, stir after heating 35 DEG C, static 24 hours, add mixed fermentation liquid 1, under the water vapor atmosphere of 55 DEG C, carry out sealing 1 hour, then as ambient temperature curing 12 hours, obtain material 1;
3) by step 2) in material 1 to be crushed to particle diameter be 5mm, add poultry manure and mix, obtain material 2;
4) stack retting: corrugate, layer overlay straw on ditch, by step 3) material 2 that obtains is placed on straw, and spray lime and water, seal stack retting with coverture, stack retting humid control is 50%, and stack retting temperature is 60 DEG C.
Use the microorganism fertilizer that the present invention prepares, can execute around crop root part, 280kg/ mu, base manure ditch spread can be mixed or spread fertilizer over the fields, after executing, return soil.The increasing crop yield 25% of finally planting out, subterranean pest-insect hazard ratio is 1%, and every gram is 200,000,000 containing the probiotics number of living, and soil is without the phenomenon that hardens.
Embodiment 2
1) Lactobacterium acidophilum, bifidus bacillus, actinomycetes and water are put in vessel according to the ratio that mass percent is 1: 1: 1: 3, drip acid, the PH of solution is adjusted to 5, under the water vapor atmosphere of 70 DEG C, carries out sealing and fermenting, fermentation time is 3 hours, obtains mixed fermentation liquid 1;
