Beneficial bacteria. Compared with organic fertilizer and bio-fertilizer, it not only has more active beneficial bacteria, but also increases the production cost in the production process due to the addition of strains! The microorganisms in nature are “ubiquitous, no time, no matterâ€, whether it is air or not. There are a large number of microorganisms in rivers, grounds, deep seas of several kilometers deep, and animal and plant organisms. Due to the nature and metabolism of various microorganisms, they are divided into beneficial microorganisms and harmful microorganisms.
Harmful microorganisms oxidize organic substances, causing food deterioration, mold, equipment decay, poisoning, this process is the result of the activation and growth of pathogenic microorganisms and spoilage bacteria; and microbial live bacteria are beneficial and effective microbiota, It can synthesize antioxidant substances and inhibit and kill pathogenic microorganisms and spoilage bacteria. "Active Probiotics" is not only a nemesis for the survival of various diseases of plants, but also a nemesis of various pollutions.
The addition of beneficial bacteria in fertilizers is made by industrial cultivation, and the biological strains have different effects.
Below we understand the role of various strains.

15. Lactic acid bacteria group: It has strong bactericidal ability, can effectively inhibit the activity of harmful microorganisms and the rapid spoilage decomposition of organic matter, and can decompose lignin and cellulose which are not easily decomposed under normal conditions, and ferment and decompose organic matter. Lactic acid bacteria can also inhibit the proliferation of pathogenic bacteria caused by continuous cropping disorders.
16, yeast group: synthesis of active substances that promote root growth and cell division, and promote the supply of other effective microorganisms (food) to provide important feeding guarantee
Bacillus coagulans: It can reduce harmful gases such as ammonia and hydrogen sulfide in the environment. Increase the content of amino acids in the fruit.
17, Aspergillus oryzae: Make the organic matter in the straw the nutrients needed for plant growth, improve the soil organic matter, and improve the soil structure. Decomposes protein, cellulose, hemicellulose, lignin, etc., and combines thermophilic, heat-resistant bacteria, fungi, yeast strains and related decomposing enzymes. It has strong degradation ability and can simultaneously raise temperature, deodorize and eliminate pests and diseases. , weed seeds and the effect of improving nutrients,
18, Aspergillus niger: cracking macromolecular organic matter and insoluble inorganic matter, facilitating the absorption and utilization of crops, improving soil structure, enhancing soil fertility, and increasing crop yield. ,
19. Trichoderma viride: It is one of the strains with the highest cellulase activity. The cellulase produced has a degrading effect on crops, and the effect is very good. At the same time, it is a resource-rich antagonistic microorganism with protection and treatment. Double effect, can effectively prevent soil-borne diseases.
20, Trichoderma harzianum: used to prevent plant diseases caused by pathogenic bacteria such as Pythium, Rhizoctonia solani, Fusarium, Rhizopus oryzae, Rhizopus, Sclerotinia, and sclerotium.
21, Beauveria bassiana: in the natural conditions through the body wall contact infection to kill pests
22, Metarhizium: a class of insecticidal fungi that can parasitize a variety of pests, enter the pest through body surface invasion, and continuously increase in the pests through consumption of nutrients, mechanical penetration, toxin production, and continuous pest population Spread in the middle, causing the pest to die. ,
23, EM bacteria: from Bifidobacterium, lactic acid bacteria, Bacillus (Bacillus licheniformis, Bacillus subtilis, Bacillus licheniformis, Bacillus thuringiensis, etc.), photosynthetic bacteria, yeast, actinomycetes, acetic acid bacteria and other single strains High-efficiency compound microbial strains which are separately expanded, fermented and spray dried by special techniques

Look at the benefits of adding organic fertilizers:
Soil organic matter contains various nutrients needed for plant growth and development, and is also an important source of phosphorus, sulfur, calcium, magnesium and trace elements in soil. At present, the soil problem is highlighted, and it is urgent to supplement organic matter. The following are the specific effects of soil organic matter.
1. Promote the growth and development of crops.
Humic acid in organic matter can enhance plant respiration, increase cell membrane permeability, and enhance the absorption of nutrients. At the same time, vitamins and some hormones in organic matter can promote plant growth and development.
2. Improve soil structure.
The humus in organic matter is the main binder of soil aggregates. On the one hand, it can reduce the viscosity of sticky soil, reduce the resistance of farming and improve the quality of farming; on the other hand, it can improve the agglomeration of sand and improve its excessive Loose state.
3, improve soil water and fertilizer capacity.
The organic colloid in the soil organic matter has a strong adsorption capacity, which can improve the ability of the soil to maintain fertilizer and water storage, and also improve the buffering of the soil to acid and alkali.
4. Promote soil microbial activities.
Soil organic matter supplies the energy and nutrients needed by soil microbes to facilitate microbial activity. The energy substances and nutrients required for soil microbial life activities are directly and indirectly derived from soil organic matter, and the humus can regulate the acid-base reaction of the soil and promote the improvement of physical properties such as soil structure, which is beneficial to the activities of microorganisms. This promotes the ability of various microorganisms to convert substances. Soil microbial biomass increased with the increase of soil organic matter mass fraction, and there was a significant positive correlation between the two. However, due to the low mineralization rate of soil organic matter, it does not have a rapid stimulating effect on microorganisms like fresh plant residues, but provides energy for microorganisms in a stable and stable manner.
Because of this, soil fertility with a lot of organic matter is stable and long-lasting, and it is not easy to produce crops that are violent or de-fertilized.
5. Increase soil temperature.
The organic matter is a dark substance, generally brown to dark brown, and has a strong heat absorption property, which can raise the ground temperature. Can improve soil thermal conditions.
6, improve soil nutrient.
The humus in organic matter has complexation, and the humus can form a complex or chelate with phosphorus, iron and aluminum ions, avoiding the precipitation of poorly soluble phosphate and increasing the amount of effective nutrients.
7, promote the physiological activity of plants
Humic acid can promote the physiological activity of plants at a certain concentration.
(1) The dilute solution of humate can change the sugar metabolism in plants, promote the accumulation of reducing sugars, and increase the osmotic pressure of cells, thereby enhancing the drought resistance of crops. Fulvic acid is also a major component of certain drought-tolerant agents.
(2) It can increase the activity of catalase, accelerate seed germination and nutrient absorption, thereby increasing growth rate.
(3) It can enhance the respiration of crops, increase the permeability of cell membranes, thereby increasing their ability to absorb nutrients, accelerate cell division, and enhance root development.
8, reduce pollution of pesticides and heavy metals
Humus helps to eliminate pesticide residues and heavy metal pollution in the soil and the toxicity of Al, Mn and Fe in acidic media. In particular, brown humic acid can increase the solubility of certain pesticides such as DDT and triazabenzene remaining in the soil, accelerate the leaching of the soil, and reduce pollution and toxicity. Humic acid can also complex with certain metal ions. Due to the water solubility of the complex, toxic metal ions may be discharged with water, reducing crop damage and soil pollution.
Through the comparison of the above strains and organic matter, we can clearly distinguish the mystery of the price of bacteria-containing fertilizers in new fertilizers. The functions of the two fertilizers are different. The fertilizers containing bacteria and organic matter must be high, and the fertilizer containing organic matter does not necessarily contain bacteria.
