Description
Technical field
The present invention relates to a kind of liquid selenium-enriched organic fertilizer and preparation method thereof, belong to selenium-rich organic fertilizer production technology neck
Domain.
Background technology
Selenium is a kind of necessary trace element with physiologically active of human body, with very high value medical health care, human body
Selenium deficiency can induce a variety of diseases.Selenium can strengthen immunity of organisms simultaneously, including cellular immunity, humoral immunity and non-specificity are exempted from
Epidemic disease.But, the content of selenium is very dilute micro- in the earth's crust, and air and industrial pollution further destroy absorbing for Selenium By The Plants, make
Obtain mankind's selenium deficiency state increasingly serious.Moreover, China's overwhelming majority area is all in poor selenium area, majority's body is interior to lack selenium member
Element.Therefore, selenium-supply is particularly important for the fitness for improving our people.Domestic selenium-supply source, mainly inorganic at present
Compound sodium selenite etc..This kind of product has the shortcomings that absorptivity is low, toxicity is high, thus adds inorganic in production estimation
Selenium can not only reach preferable se complementary effect, and also environment can be polluted, and form potentially hazardous to human body.And pass through
Selenium element is enriched in the microorganism selenium produced in the cell protein structure of microorganism, belongs to organic selenium source, human body pair is being met
After the psychological need of selenium, it can also be stored in human body, it is to avoid selenium deficiency again in a short time.But, this quasi-microorganism selenium is due to life
Production. art is complicated, and cost is higher, and yield is again relatively low, on the one hand can not meet the demand of people's selenium-supply, on the other hand higher valency
Lattice make ordinary consumer be difficult to receive.
Kitchen garbage is the discarded object after food processing process and diet consumption.Comparison of ingredients is complicated, containing oil, water, consolidates
Body residue mixing vegetables, pericarp, fruit stone, rice and flour, fish, meat, bone and useless tableware, paper handkerchief etc..Kitchen garbage content of organics height,
Moisture content is high, therefore easily rotten, rotten.Leakage water meeting polluted-water, air, the influence city appearance of the city and human settlement.And eat
Kitchen rubbish is the resource discarded object that can be recycled, if using appropriate processing method to it, kitchen garbage can turn waste into wealth,
Turn harm into good.Biogas fermentation technology has with low cost, product resource efficiency high, it is easy to accomplish the characteristics of engineer applied, is
Handle kitchen garbage at present and carry out the best-of-breed technology of resource reutilization.But, it is simple to utilize biogas fermentation technical finesse kitchen
The cost of rubbish is too high, and the benefit of the generation such as biogas and biogas slurry for being produced in processing procedure is relatively low, causes to utilize biogas fermentation
The pattern of technical finesse kitchen garbage can not large-scale promotion.
The content of the invention
Biogas fermentation is utilized to provide a kind of production technology simplicity, the relatively low microorganism selenium fertilizer of production cost, and improving
The benefit that technical finesse kitchen garbage is obtained, the present invention provides a kind of liquid selenium-enriched organic fertilizer and preparation method thereof, uses this
The liquid selenium-enriched fertilizer that method is produced, serves not only as organic fertilizer and provides the nutrients such as nitrogen, phosphorus, potassium for crops, its institute
The microorganism selenium contained also provides organic selenium source for crops, while being crops increase yield, raising quality, also makes selenium-rich
Corps nutrient value afterwards is higher, indirectly improves the commercial value of liquid selenium-enriched fertilizer, biogas is utilized so as to improve
The benefit that fermentation technique processing kitchen garbage is obtained, makes using the call by pattern of biogas fermentation technical finesse kitchen garbage to push away
Extensively, the reluctant problem of kitchen garbage is solved.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of liquid selenium-enriched organic fertilizer, adds the 2.5mol/L of raw material volume 2% to 3% sodium selenite in biogas fermentation material
The urea of solution and raw material volume 1.5% to 2.5%.
It can be prepared as follows：Sodium selenite solution is uniformly mixed simultaneously with biogas fermentation material in proportion with urea
Stirring, the substrate after stirring is added and fermented in methane-generating pit, is fermented 20 to 25 days under conditions of 35 DEG C or so, draws natural pond
Upper strata biogas slurry and it is transferred in gas pond in storage tank, adds the calcium superphosphate solution of material liquid volume 0.1% to 0.2%, add
The urea liquid of material liquid volume 0.5% to 1.5%, is staticly settled 18 to 24 hours after being sufficiently stirred for, and is drawn after solution-stabilized
Supernatant liquor is preserved with 150 mesh sieve net filtrations, finally sealed, obtains liquid selenium-rich organic fertilizer product.
The beneficial effects of the invention are as follows：All raw material is without noxious materials such as heavy metal cadmium, lead, arsenic, chromium, in microorganism
Live body roundworm egg, Escherichia coli and other harmful bacterias have been killed in fermentation process, kitchen garbage has been solved reluctant
Problem, and there is provided a kind of preparation method of microorganism selenium fertilizer.The a large amount of organic matters and humic acid contained in fertilizer, can improve soil
Earth biochemical activity, improves disease-resistant crops insect prevention ability, reduces interionic antagonism, alleviates soil hardening to a certain extent
Problem.The present invention can make that plant roots are deep, full of leaves, stem strong, increase crop yield；Crops can be made to be rich in needed by human body simultaneously
Various nutrient elements, and help human body to supplement lacked selenium and other trace elements, improve agricultural products in China in the international market
Competitiveness, increases the value of green organic farm products；The biochemical activity of soil can also be improved in addition, reduce making for chemical fertilizer
Consumption, safeguards that soil ecology is balanced.
