The role and use of microbial fertilizer

With the development of modern agricultural technology, there are more and more types of fertilizers , including foliar fertilizers , rooting agents, microbial fertilizers , etc. These fertilizers have different functions, but they all have a significant promoting effect on the growth of crops. Let’s talk about the role and use of microbial fertilizers.

1. What is microbial fertilizer?

Microbial fertilizer is generally speaking a kind of fertilizer containing microorganisms. This kind of fertilizer not only contains a large number of beneficial microorganisms, but also contains a large amount of organic matter. This kind of microorganism can multiply in large numbers in the soil and has many functions such as improving fertilizer utilization rate , preventing and controlling diseases, improving soil, improving product quality, and increasing yield.

2. The role of microbial fertilizer

1. Improve soil environment

In the past, farmers tended to prefer using traditional large-scale chemical fertilizers. Over time, nutrients in the soil were lost, and problems such as soil compaction and salinization occurred. At this time, it is necessary to change direction in time, use microbial fertilizers, adjust the physical properties of the soil, loosen the soil, and retain water and fertilizer.

2. Stimulate crop growth

The microorganisms in the bacterial fertilizer will remain active in the soil, and in the process they will produce a large amount of gibberellins and cytohormones. After coming into contact with the plant roots, these substances will regulate the metabolism of the crops, thereby stimulating crop growth and achieving increased production and income.

3. Improve fertilizer utilization

Some microorganisms can decompose the phosphorus and potassium elements fixed in the soil and release them for crops to absorb and utilize, and absorb and utilize nitrogen in the air to synthesize "ecological nitrogen fertilizer".

4. Increase production and improve quality

Microorganisms can secrete a variety of enzymes in the soil. These substances can decompose various ions such as phosphorus, potassium, iron, copper, etc. in the soil and be absorbed and utilized by crops, thereby improving nutrient utilization and increasing crop yield and quality.

5. Disease prevention and control

Beneficial microorganisms multiply rapidly in the soil, forming dominant populations in the micro-ecosystem of the crop rhizosphere soil, preventing or inhibiting the growth and reproduction of other harmful bacteria and their harm to crops. During the reproduction process, they also produce active substances such as subtilisin, polymyxin, nystatin, and gramicidin. These active substances have a significant inhibitory effect on pathogenic bacteria in the soil and even have a killing effect on some harmful pathogens, reducing the chance of harm from harmful microorganisms.

3. How to use microbial fertilizer

1. Use for seedling cultivation

Adding it to the nutrient soil during seedling cultivation can not only promote root growth and make the seedlings stronger, but also prevent the occurrence of diseases such as damping-off disease, damping-off disease, and root rot in the seedling stage.

2. Used as base fertilizer

When applying base fertilizer to crops, microbial fertilizer can be used together with organic fertilizer , compound fertilizer and other fertilizers. This can not only improve the utilization rate of fertilizer, but also inhibit pathogens in the soil.

3. Used for seed dressing

Before sowing crops, soak the seeds in clean water, take them out, mix them with microbial fertilizer, make the surface of the seeds evenly covered with fertilizer, and then dry them in a cool and ventilated place before sowing. It can prevent seeds from being infected with diseases.

4. Use by spray

Microbial fertilizer can be filtered and sprayed directly on the leaves of crops. The living spores use the nutrients and water on the leaves to reproduce on the leaves, quickly occupying the entire leaf surface, and at the same time secrete active substances with bactericidal effects, thereby effectively repelling, inhibiting and killing pathogens. Prevent bacterial infection and the occurrence of diseases.
