Description
Technical field
The present invention relates to agriculture microbial manure technical field, more particularly to a kind of composite microbiological fertilizer and its preparation
Method.
Background technology
Resource and environment problem is one of problem that the world today mankind very pay attention to.China is used as hair maximum in the world
Country in exhibition, populous, resource and environment problem is on the rise.In recent years, due to excessively cutting down, overgrazing, industry with
A large amount of discharges of sanitary wastewater, a large amount of of agriculture chemical use, and cause to become serious to the pollution mouthful of environment, and serious jeopardizes
The health of the people, threatens the existence of the mankind.Particularly at present, due to the growth of whole world agricultural and fertilizer application amount, to agriculture
The dependence mouthful benefit enhancing of medicine and chemical fertilizer, causes organic fertilizer and uses deficiency, soil nutrient out of proportion, soil hardening, soil matter
A series of problems, such as amount decline, river and underground water pollution.Avoid following covering for developed country " first pollution destruction, administer afterwards "
Rut, the new agriculture usage amount it is necessary to reduce agricultural chemicals and chemical fertilizer of development " sustainable development ", finds effective substitute.
Composite microbiological fertilizer is according to rhizosphere soil microecology and plant battalion physiological principle, with multifunctional microbial
Active bacteria (with nitrogen bacterium, phosphate solubilizing bacteria, B. mucilaginocus) is core, with fertilizer type organic matter as carrier, then is equipped with a small amount of inorganic
Nutrient and trace element process with pollution-free, nuisanceless, be suitable to produce the new-type fertilizer of pollution-free food.It is this new
Fertilizer can draw and be implanted with beneficial microorganism dominant group to crop rhizosphere soils again to crops fertilizer, reach infertile field strong sprout, promote
The purpose of biological and ecological methods to prevent plant disease, pests, and erosion disease and good quality and high output.According to the requirement of Ministry of Agriculture composite microbiological fertilizer professional standard NY/T798-2004, have
Effect viable count is the key technical indexes of this product, and living bacteria count amount have to be larger than 2,000 ten thousand/gram, total nutrient (N+P2O5+
K2O) have to be larger than 6%.But ensure number of viable high, the support material for accounting for product formula ratio 70%-80% is influence
The principal element of number of viable.
CN101928186A discloses a kind of composite microbiological fertilizer of controlling crop diseases and insect pests, with following raw material and
Into：Composite microbial fertilizer bactericide, insecticidal synergist, plant growth regulator, turf, expanded chicken manure, inorganic fertilizer and bonding
Agent；This have controlling crop diseases and insect pests function composite microbiological fertilizer can using seed dressing, various fertilising sides such as make base manure, topdress
Formula is applied to various crops such as cucumber, tomato, ginger, watermelon, peach, peanuts, is had and significantly reduce pest and disease damage, improves and make
The effect of article matter and increase yield.CN102515951A discloses a kind of Tobacco composite microbial fertilizer, comprising active function
Bacterium component, organic fertilizer component, inorganic fertilizer component；The fertilizer has organic fertilizer, inorganic fertilizer, active function microbial manure three concurrently
Person's advantage, can guarantee that active function microorganism survives for a long time under hypersaline environment, can prevent soil degradation, reduce soil-borne disease
Incidence, improves cigarette quality and yield.
However, existing microbial manure also has the following disadvantages：1. main airborne as having by the use of turf or humic acid
Body；2. viable bacteria is contained in composite microbiological fertilizer, and the drying in granulation process has a great impact to number of viable, product forms
Mainly based on powdery；3. disk and drum granulating balling ratio are low, and particle is irregular, rough, have impact on the outer of product
Appearance quality.Therefore, prepare that a kind of microorganism survival rate high, fertilizer excellent quality, fertilizer efficiency are notable, antibacterial is disease-resistant, increasing both production and income
Crops microbial manure is one of important directions of technology development.
The content of the invention
It is disease-resistant, increasing both production and income compound micro- present invention aim to provide a kind of notable fertilizer efficiency, safety and environmental protection, antibacterial
Bio-feritlizer and preparation method thereof.
To achieve the above object, the present invention is achieved by the following scheme：
A kind of composite microbiological fertilizer, counts by weight, and the microbial manure is by 20-40 parts of microbial organic fertilizer group
Divide, 60-80 parts of inorganic fertilizer component and 4-6 parts of active microorganism bacterium component are constituted；Wherein, the microbial organic fertilizer component
For：By bacillus subtilis, bacillus amyloliquefaciens and azotobacter chroococcum by volume 2：2：After 1 mixing, with 0.1-0.4%'s
Inoculum concentration is inoculated in the mixture of furfural dregs, dregs of beans and plant ash the fermentation 10-15d that banks up, then in a low temperature of 10-20 DEG C
Dry, make the water content of fermentate between 15-25%；The active microorganism bacterium component contains：The huge gemma bar of phosphorus-solubilizing bacteria
Bacterium bacterium powder, potassium solubilizing bacteria bacillusmusilaginosiengineering bacterium powder and AMF bacterium powder；The inorganic fertilizer component is：Calcium superphosphate
10-35wt%, potassium sulfate 10-30wt%, urea 5-15wt%, potassium chloride 10-30wt%, zinc sulfate 5-10wt%, magnesium sulfate
5-15wt%, clay 5-10wt%.
Wherein, the weight ratio of each bacterium powder is in the active microorganism bacterium component：Phosphorus-solubilizing bacteria bacillus megaterium bacterium powder：Solution
Potassium bacterial jelly sample bacillus bacterium powder：AMF bacterium powder=2~3：1.5~2.5：1~3.
Preferably, the inorganic fertilizer component is：Calcium superphosphate 25wt%, potassium sulfate 20wt%, urea 15wt%, chlorination
Potassium 15wt%, zinc sulfate 5wt%, magnesium sulfate 10wt%, clay 10wt%.
Living bacteria count is 2 × 10 in the composite microbiological fertilizer9~2 × 1010Individual, total nutrient N+P2O5+K2O is 15
~30%, the content of organic matter is 20-40%.
In addition, present invention also offers the preparation method of the composite microbiological fertilizer, specifically including following steps：
(1) inorganic fertilizer component granulation：By calcium superphosphate, potassium sulfate, urea, potassium chloride, zinc sulfate, magnesium sulfate and clay
Mix in proportion, slurry-spraying pelletizing, after drying, sieve takes the particle of particle diameter 1-3mm, obtains final product inorganic composite fertilizer component；
(2) by weight by microbial organic fertilizer component, inorganic fertilizer component, active microorganism bacterium component and 10-15 parts
Embedding medium, 4-8 part of bonding powder carries out mixing embedding, is pelletized at 10-20 DEG C afterwards, pelletizes after 10-20 DEG C of cryogenic vacuum
Dry, that is, obtain composite microbiological fertilizer.
And described embedding medium is that, with the sodium alginate of 2-3%, soluble in water being made of the polyvinyl alcohol of 6-7% mixes molten
Autoclaving is obtained after liquid.
The particle diameter of the embedded particles is 1-4mm.
The beneficial effects of the invention are as follows：(1) present invention carries out microbial fermentation and obtains microorganism to organic fertilizer component first
Organic fertilizer component, can effectively lift N, P, K content in fertilizer, lift fertilizer efficiency；(2) it is of the invention by microbial organic fertilizer group
Divide, inorganic fertilizer component and active microorganism bacterium component are prepared by certain proportioning, after gained incorporation of fertilizerin the soil, by it
In bacterial strain quickly breeding causes that the nutrient potentiality of environment are given full play to, and a large amount of fresh corruption for producing during the fermentation
Mass-energy improved soil is grown, soil fertilizer, fertilizer and venting and water permeable ability is improved, stimulates plant growth, increase the confession of plant nutrient
