Answer: (1) Improve soil fertility. This is the main effect of biofertilizers, such as various autogenous, combined or symbiotic nitrogen-fixing biofertilizers, which can fix nitrogen in the air and increase nitrogen content in the soil; A variety of microorganisms that decompose phosphorus and potassium minerals, such as silicate bacteria, can decompose potassium feldspar, mica and phosphate rock in the soil, so that the insoluble phosphorus and potassium in them are effective.
2) Manufacture and assist crops in absorbing nutrients. After the application of some bacterial fertilizers such as "5406" antibiotic fertilizer, due to the activity of microorganisms, it can not only increase the effective nutrients of the soil, but also produce a variety of hormones and various vitamins, thereby promoting the growth of crops; The nitrogen provided by rhizobia in rhizobia fertilizer to leguminous plants accounts for 30% to 80% of their lifetime requirements; Va mycorrhizae is a soil fungus that can live in symbiosis with a variety of plant roots, and its hyphae extend far from the roots and can absorb more nutrients for various plants to use, among which the absorption of phosphorus is the most obvious.
3) Enhance the stress resistance of plants. After inoculation, some biofertilizer strains become the dominant bacteria in the rhizosphere of crops due to their massive growth and multiplication in crop roots, and they can secrete antibiotics against fungi and bacteria, thereby inhibiting the growth of a variety of pathogens. Due to the large growth of mycorrhizal hyphae in the roots of crops, in addition to absorbing nutrients that are beneficial to the growth of crops, they can also increase the absorption of water by crops and improve the drought resistance of crops.

Biological fertilizer is a new type of biological "fertilizer" that has emerged in recent years, although it is called bacterial fertilizer, but its essence is not fertilizer, but only some beneficial bacteria that are beneficial to the soil and crops cultivated in the soil by means of some factories.
Function. More than three kinds of compound bacteria promote and complement each other, and the effect of resistance to soil-borne diseases is much greater than that of a single species. The beneficial flora synergizes with each other and works together to achieve high yields and high yields.
Increase crop yields.
Improve crop quality.
Enhance crop stress resistance.
Improve fertilizer utilization.
Improve the soil environment.

Answer: Biofertilizer relies on the role of microorganisms to increase yield, and its effectiveness depends on excellent strains, high-quality bacteria and effective application methods. Therefore, the principles of rational application of biofertilizers are:
First, it is necessary to ensure that the fertilizer has a sufficient number of effective microorganisms; Second, it is necessary to create environmental conditions suitable for the growth of beneficial microorganisms.
1) Biological fertilizers must be of qualified quality, and those of inferior quality and expired cannot be used. The fertilizer must be kept at low temperature (optimal temperature 4 10), cool, ventilated and protected from light to avoid invalidation.
2) In order to minimize the death of microorganisms, direct sunlight should be avoided during application; Add an appropriate amount of water when dressing seeds, so that the seeds are completely adsorbed. After seed dressing, it is necessary to sow and cover the soil in time, and should not be mixed with pesticides and fertilizers.
3) The direct application effect of general bacterial fertilizer in acidic soil is poor, and it is necessary to cooperate with the application of lime, plant ash, etc., to strengthen the activity of microorganisms.
4) Sufficient water is needed for microbial growth, but too much water will cause poor ventilation and affect the activity of aerobic microorganisms. Therefore, attention must be paid to timely drainage and irrigation to maintain the right amount of moisture in the soil.
5) Most of the microorganisms in biofertilizers are aerobic, such as rhizobia, autogenous nitrogen-fixing bacteria, phosphorus bacteria, etc. Therefore, the application of bacterial fertilizer must be combined with soil improvement and reasonable tillage to keep the soil loose and well aerated.
6) Microbial activity requires the consumption of energy. Organic matter is the main energy source of microorganisms, and the decomposition of organic matter can also provide microbial nutrients. Therefore, the application of biofertilizers must be accompanied by the application of organic fertilizers.
7) Microbial growth requires a variety of nutrients. Therefore, it is necessary to have sufficient nitrogen, phosphorus, potassium and trace elements. For example, in the early stage of leguminous crop growth, an appropriate amount of nitrogen must be used to promote crop growth and root nodule development, and increase nitrogen fixation; Phosphorus fertilizer can play the role of "increasing nitrogen with phosphorus"; Appropriate amount of potassium and calcium nutrition is conducive to the proliferation of microorganisms; Molybdenum is an indispensable element for the synthesis of nitrogenase by rhizobia, and the combined application of molybdenum fertilizer and rhizobia fertilizer can significantly improve the nitrogen fixation efficiency.

To put it bluntly, it is a "fertilizer" made of microorganisms that are beneficial to soil and plants. Its main function is not to provide nutrients to plants, but to improve the soil environment, regulate the plant's own functions, and enhance the growth ability of plants.
We all know that yogurt is better for the human body than fresh milk, especially for people with gastrointestinal problems. This is the same as biological fertilizer: if chemical fertilizer, organic fertilizer, etc. are compared to fresh milk, biological fertilizer becomes lactic acid bacteria, and biological bacterial fertilizer and chemical fertilizer organic fertilizer are together to become yogurt.
I wonder if this explanation is understood?

Biological fertilizer is a living fertilizer, and its role is mainly completed by the life activities of a large number of beneficial microorganisms contained in it. Only when these beneficial microorganisms are in vigorous reproduction and metabolism can the transformation of substances and beneficial metabolites continue to be formed. Therefore, the types of beneficial microorganisms in microbial fertilizers and whether their life activities are vigorous are the basis of their effectiveness, unlike other fertilizers based on the form and amount of major elements such as nitrogen, phosphorus, and potassium.
Because microbial fertilizer is a living preparation, its fertilizer efficiency is closely related to the number and intensity of live bacteria and the surrounding environmental conditions, including temperature, moisture, pH, nutritional conditions and the rejection of indigenous microorganisms in the soil.

To improve the soil, the traditional Chinese medicine biological fertilizer can play a good role in improving the soil, and even better with humic acids, which is obvious to all in improving soil fertility.
Traditional Chinese medicine biological fertilizer is based on traditional Chinese medicine extract as the carrier, adding a variety of beneficial microorganisms, plant proteins, amino acids, trace elements, small molecule polypeptides, etc., which can be quickly absorbed by plants and promote growth. Traditional Chinese medicine biological fertilizer is rich in a variety of beneficial bacteria, which become the dominant bacteria in the rhizosphere of crops through its large growth and multiplication in the rhizosphere of plants, compete for nutrients with harmful bacteria in the soil, and form antagonism, which can effectively enhance crop resistance and prevent various pests and diseases.
Precautions for the use of bacterial fertilizer.
The amount of biological fertilizer is small, and it is not easy to apply evenly alone, and it is easy to be affected by sunlight before covering the soil, and the problem of being blown away by the wind will occur on windy days. Therefore, when used as base fertilizer, under the condition of applying organic fertilizer, the biological fertilizer and organic fertilizer should be mixed in a ratio of 1::500, covered after spraying with water, composting for 3-5 days, and applying after smashing once in the middle.
When applying, it should be evenly applied in the ditch, and then the ridge should be formed; If no organic fertilizer is applied, mix 30-50 kg of slightly moist fine soil with 1 kg of biological fertilizer, evenly apply it to the ditch, and then ridge and cover the soil. In paddy or dry fields, it can also be evenly spread on the surface, and then immediately raked into the soil, and can not be exposed to the sun for a long time.

1. Biofertilizer is also known as biological fertilizer, bacterial fertilizer, bacterial fertilizer or inoculant, etc., but most people are used to calling it bacterial fertilizer. To be precise, biofertilizer is a fungus rather than a fertilizer, because it itself does not contain the nutrients needed for plant growth and development, but only contains a large number of microorganisms, which improve the nutritional conditions of crops through the life activities of microorganisms in the soil.
2. Improve the fertility of soil before repentance. This is the main effect of microbial fertilizers, such as various autogenous, combined or symbiotic nitrogen-fixing biofertilizers, which can fix nitrogen in the air and increase the nitrogen content in the soil; A variety of microorganisms that decompose phosphate and potassium ore precursors, such as silicate bacteria, can decompose potassium feldspar, mica and phosphate rock in Bixian Qing soil, so that the insoluble phosphorus and potassium in them can be effective.
3. Manufacture and assist crops to absorb nutrients. After the application of some bacterial fertilizers, due to the activity of microorganisms, it can not only increase the effective nutrients of the soil, but also produce a variety of hormones and various vitamins, thereby promoting the growth of crops.
4. Enhance the stress resistance of plants. After inoculation, some microbial fertilizer strains become the dominant bacteria in the rhizosphere of crops due to their large growth and multiplication in crop roots, and they can secrete antifungal and bacterial antibiotics, thereby inhibiting the growth of a variety of pathogens.

As the name suggests, bacterial fertilizer is bacteria + fertilizer, bacteria are all kinds of beneficial microorganisms, fertilizer can be organic fertilizer, can also be nitrogen, phosphorus, potassium, trace elements and other inorganic fertilizers, the main advantage of bacterial fertilizer is the function of beneficial bacteria!
Compared with ordinary chemical fertilizers, microbial fertilizers can improve the symbiotic nitrogen fixation efficiency of crops, improve soil quality, resist salinity, resist heavy cropping, and can effectively increase crop productivity when applied together with organic fertilizer. Traditional chemical fertilizers have caused many problems in China's land. One of the most important problems is land salinization, compaction, the Ministry of Agriculture has canceled a series of preferential measures for chemical fertilizers, and does not advocate the use of chemical fertilizers, so microbial fertilizers are the trend, recommended, rolling green microbial science and technology research rich farmer series products, more than 15 billion microbial agents per gram, there is a lot of relevant information.
