The difference between microbial bacterial agent and microbial fertilizer

Microbial fertilizers: products containing specific living microorganisms, applied to agricultural production, increase the supply of plant nutrients or promote plant growth, improve yields, and improve the quality of agricultural products and the agroecological environment through the life activities of the microorganisms contained therein.

Microbial fertilizer includes microbial inoculant (agricultural microbial bacterial agent), compound microbial fertilizer and bio-organic fertilizer.

1, Agricultural microbial inoculant: the target microorganisms (effective bacteria) through industrial production and expansion of the processing of live bacterial preparations, it has direct or indirect soil improvement, restoration of ground strength, maintenance of inter-root microbiota balance, degradation of toxic and harmful substances, etc.; applied to agricultural production, through the life activities of the microorganisms contained in it, increase the supply of plant nutrients or promote plant growth, improve the quality of agricultural products and agricultural ecological environment. quality and agro-ecological environment.

2, Compound microbial fertilizer: the purpose of the living bacteria products made by the industrial production of biological multiplication and nutrient compound.

3, Bio-organic fertilizer: A kind of fertilizer with microbial fertilizer and organic fertilizer effect, which is compounded by specific functional microorganisms and organic materials mainly from animal and plant residues (such as animal and poultry manure, crop straw, etc.) as the source and harmlessly treated and decayed. 

The difference between microbial bacterial agent and microbial fertilizer.

Microbial agent is the abbreviation of agricultural microbial agent, which refers to the living product formed by 1 or more kinds of target microorganisms directly used after industrial production and expansion or only adsorbed with the carrier that is conducive to the survival of the culture, it is one of the categories of bacterial fertilizer.

Bacterial fertilizer is the abbreviation of microbial fertilizer by the people and some dealers, it refers to the target microorganisms after industrial production and expansion and nutrients and other composite products, containing the culture of living products, it is larger in the amount per unit area, currently can be divided into compound microbial fertilizer, bio-organic fertilizer and agricultural microbial agents, i.e., covering bacterial agents.

Bacterial fertilizer is generally packaged larger, mostly 40kg, there are also 25kg and 50kg package, the general mu dosage is larger, according to the current mu organic matter content of about 1.0% across the country, the general fruit trees to about 200-500kg. Large fertilizer bacterium fertilizer current market price is more concentrated in between 2000-3000, has gradually become the mainstream of the market fertilizer. General compound microbial fertilizer and bio-organic fertilizer use more than 200kg per mu, while the amount of agricultural microbial mycorrhizal agent on the unit area is less, generally 2-5kg per mu.

General agricultural microbial fungicides are referred to as fungicides, which are small fertilizers and dispensing agents. The compound microbial fertilizer and bio-organic fertilizer is referred to as bacterial fertilizer, which is a big fertilizer.

The connection between microbial bacterial agent and microbial fertilizer

In the development of national standards, microbial bacterial agent is a class of microbial fertilizer, currently in the microbial agent product registration of 152 strains, the top 10 strains used more frequently are: Bacillus subtilis, jelly-like Bacillus, Bacillus licheniformis, Bacillus megaterium, Bacillus amyloliquefaciens, Saccharomyces cerevisiae, Bacillus lateralis short spore, Streptomyces fine yellow, Lactobacillus plantarum, Aspergillus niger. Among them, Bacillus accounts for 75%.

At present, when promoted in the market, microbial fungicides are divided into: rhizobacteria, nitrogen fixing bacteria, phosphorus solubilizing microbial fungicides, silicate microbial fungicides, photosynthetic bacterial fungicides, organic material ripening agent, growth promoting fungicides, mycorrhizal fungicides, bioremediation fungicides; the dosage form is mainly liquid, but also powder and granule type.

According to different crops in different areas, microbial fungicides are mostly used in four ways: as a base fertilizer with a dosage of 2kg per mu, evenly spread when plowing; as a chasing fertilizer with a dosage of 1-2kg per mu; as a drip irrigation and flushing, taking the clear liquid with conventional fertilizer for watering, and the residue as a base fertilizer to improve the soil; as a seed fertilizer, mixing the seed in appropriate amount, and using it according to the conventional seedling or sowing method.
