Description
Technical field
The present invention relates to the production method of fertilizer, the method for preparing organic fertilizer in particular to fermentation method.
Technical background
It is well known that phosphorus ore will generate a large amount of phosphorite tailings after ore dressing, component characteristics are wherein P2O5Quality point
Number≤10%.Because of low, the phosphorite tailings slag category industrial solid castoff containing phosphorus content.It is handled by the way of discarding or accumulation at present,
It is had some impact on to environment, therefore the utilization of phosphorite tailings is by the concern of enterprise and scholar.
Maotai-flavor liquor vinasse are the Main By products of liquor production, contain nutriment more abundant, such as albumen
Matter, fat, cellulose and various trace elements etc. have certain value of exploiting and utilizing.But water content height and acidity have become greatly
The principal element that the alcoholic that is limited grain recycles.How vinasse are effectively utilized, is to realize liquor industry maximum resource utilization
It is crucial.So the recycling research for actively developing vinasse not only can be reduced the vinasse accumulation bring wasting of resources, improve environment, also
It can be turned waste into wealth, create new social economic value.
Currently, many researchers are raw applied to fertilizer as raw material using phosphorite tailings and Maotai-flavor liquor vinasse respectively
It produces, phosphorite tailings is made by phosphate fertilizer compound fertilizer by chemical acid hydrolyzation, belong to chemical fertilizer, but providing available phosphorus to soil
It, can be because of the variation of the excessive accumulation and soil physico-chemical property of Phosphorus in Soil caused by inefficient application, to induce ring while source
Border pollution, affects to human health, brings hidden danger to food safety.However, Maotai-flavor liquor vinasse can be sent out by accumulation
Organic fertilizer is made in ferment, can avoid soil issues and environmental pollution caused by chemical fertilizer well, but because it lacks certain plants
Nutrient such as phosphorus element etc., cannot be effectively facilitated plant overall growth necessary to growing.
It is not many in relation to the application part using spirit stillage resource production fertilizer in Chinese patent database, wherein：
No. CN101255076《The production method of vinasse mixed organic manure and organic fertilizer》, disclosed technique be first pass through vinasse fermentation,
Dry obtained vinasse powder；Again using vinasse powder as Organic Ingredients, feature is planted by condition in different ground and different crops, is fitted
The mineral nutritions sources such as nitrogen, phosphorus, potassium are added in amount, and vinasse mixed organic manure and organic fertilizer is made；No. CN102992915A《A kind of benefit
With the method for distillers ' grains production environment-friendly and high-efficiency biological organic fertilizer》, disclose and carry out fermentation substrate by screw bulking machine
Expanding treatment, then be transported to and cooled down and be added microelement mineral salt in wet feed mixing machine, when temperature reduces in proportion
Inoculation mixed bacteria liquid is sufficiently mixed；It is loaded into novel silica gel respiratory membrane fermentation bag by automatic gauge packaging system,
It ferments under constant temperature in fermenting cellar, as finished product；No. CN103553736A《It is a kind of organic using waste and old tobacco rod, vinasse production
The method of fertilizer》, disclosed method is to use the leftover bits of production process of flue-cured tobacco and/or inferior grade flue-cured tobacco former as organic fertilizer
Material crushes granulating, mixes with freshly-slaughtered poultry excrement, is sufficiently mixed uniformly by mechanical stirring and microbial fermentation inoculum, at normal temperature heap
Fermentation, turning are set, decomposed fermentation materials obtain powdery or granular refined organic fertilizer material by finishing.
The patented technology with phosphorite tailings and Maotai-flavor liquor vinasse production organic fertilizer is had no at present.
Summary of the invention
The present invention is intended to provide with the method for phosphorite tailings and Maotai-flavor liquor vinasse production organic fertilizer, with effective land productivity
With phosphorite tailings and both industrial wastes of Maotai-flavor liquor vinasse, for sustainable development and improves the ecological environment new skill is provided
Art and data basis.

Bacteria suspension；The Paecilomyces lilacinus PSF7 after activation is seeded on potato glucose solid medium again, is placed in 30 DEG C of cultures
After cultivating 3d in case, fungal spore suspension is obtained by 4 layers of sterile gauze filtering；Bacterium bacteria suspension and fungal spore are modulated respectively
The concentration of suspension reaches 1 × 108CFU/mL, then be uniformly mixed with the ratio of PSF7 and PSB3 volume ratio 2: 1-2.5: 1,
Composite bacteria liquid is made；
(2) a solid state fermentation：
Example in mass ratio takes 90~94 parts of vinasse and 6~10 parts of phosphorus mine tailings to be put into fermenter, and is adjusted initially with distilled water
Moisture content is stirring while adding to 55% or so；After mixing, in mass ratio 15%~20% composite bacteria liquid is inoculated with to mixed organic matter
In, ferment 3~5d at a temperature of 25 DEG C~30 DEG C；
(3) secondary compost fermentation：
After a solid state fermentation, example in mass ratio takes 10~15 parts of stalks, 1.5~2.5 parts of quick limes, 0.7~1.2 respectively
Part urea, 1.5~2.0 parts of potassium chloride, 5~10 parts of zeolites, 3~8 parts of bentonites and 10~15 parts of medical stones are added to primary solid
In mixed organic matter after state fermentation；After mixing, 5%~10% cellulase aqueous solution, side edged are added in mass ratio
It is stirred；After mixing, it ferments under 40 DEG C~50 DEG C of greenhouse in oxygen supply abundance, well-ventilated, temperature, every 3d
Turning is primary, and 18~24d post-fermentation terminates；
(4) detect, pack：
After fermentation, it is in more uniform large grained, ordorless, no mechanical admixture gives out moist soil that material color, which is brown,
Breath；Pass through conventional detection after mixing, eligible bag distribution packaging is to get organic fertilizer products.
In (1) step of the above method, the gene order of the thermophilic narrow food unit cell PSB3 and Paecilomyces lilacinus PSF7 of malt
It has been filed on to National Center for Biotechnology Information NCBI (National Center of Biotechnology
Information) in database GenBank, sequence number is respectively MG594526 and MG148343.
In (4) step of the above method, the conventional detection qualification refers to that every main physical and chemical index meets NY-525
- 2012 organic fertilizer standards.
Inventor points out that although the content that secondary compost fermentation is selected lists many substances, but be not intended to limit using energy
It is enough in other substances for containing plant nutrient of the method for the present invention.
Inventor points out again：Fermentation process is a kind of biochemical reaction, and composting fermentation process is divided into low temperature by the present invention
Fermentation, 2 stages of mesophilic digestion, the reaction temperature of the cold fermentation of a solid state fermentation is at 30 DEG C hereinafter, secondary compost fermentation
Mesophilic digestion reaction temperature at 30 DEG C~60 DEG C.
Phosphorite tailings and Maotai-flavor liquor vinasse belong to trade waste, and with land occupation, there are latency environment danger
The features such as evil；Tradition utilizes the method drawbacks such as that there are processing costs is high, utilization rate is low.The present invention passes through two-step fermentation for phosphorus ore
Tailing and Maotai-flavor liquor vinasse " turn waste into wealth, turn harm into good ", are made the organic fertilizer for meeting national sector standard, obtain
Organic fertilizer category green product, in soil improvement, crop planting, having very high application prospect and economic effect
Benefit；For chemical phosphatic ferfilizer, the secondary pollution of environment not will cause not only, also there is certain corrosion inhibitive function.The present invention is practical
It is easy to operate, it is easy to implement, to production equipment without particular/special requirement.There are Maotai-flavor liquor vinasse again suitable for existing phosphorite tailings
