What are the functions and effects of microbial inoculants?
Microbial inoculants are made by multiplying microorganisms and using some porous substances as adsorbents. Then they are processed into an active bacterial preparation. Microbial inoculants can be used for seed dressing and root irrigation. They are very beneficial to crop growth and have many functions, and they are welcomed by many people. So what exactly are the functions of microbial inoculants? Today the editor will give you a brief introduction. Let's take a look below!
1. Increase yield and quality
Microbial inoculants can provide crops with a large amount of nutrient elements and promote crop growth. Moreover, many microorganisms can also secrete various active substances such as gibberellin and cytokinin, which are very beneficial to the growth of planted plants and can achieve the purpose of increasing yield. In addition, microbial inoculants can also improve crop quality. Professional data surveys have shown that after using microbial inoculants, the content of nutritional elements such as protein and amino acids in crops is effectively increased. They can also greatly help the development of crop fruits, grains and so on.
2. Enhance crop stress resistance
In most microbial inoculants, the microorganisms have the ability to secrete antibiotic substances. The active enzymes they contain have a very strong inhibitory effect on bacteria and can even kill them. Therefore, they can not only reduce the incidence of crop diseases and pests, but also improve crop stress resistance. For example, after using microbial inoculants, the cold resistance, drought resistance and even lodging resistance of crops are enhanced. At the same time, they can also effectively reduce some physiological diseases and avoid some unnecessary losses in planting.
3. Improve fertilizer utilization rate
Most of the microorganisms contained in microbial inoculants can decompose organic matter in the soil. When decomposing organic matter, humic acid is gradually formed. Humic acid then combines with nitrogen in the soil to form ammonium humate, which can significantly reduce nitrogen fertilizer loss. In addition, some microbial inoculants can decompose phosphorus and potassium fertilizers that have already been fixed in the soil into quick-acting phosphorus and potassium fertilizers. This improves the utilization rate of chemical fertilizers, not only reducing fertilizer input costs, but also avoiding the waste of excessive resources.
4. Improve soil nutrients
The effective bacteria in microbial inoculants can dissolve some insoluble nutrients in the soil, thereby increasing the soil nutrient content and giving crops more nutrition. Effective bacteria can also secrete many extracellular polysaccharide substances. The main function of this substance is to bind the granular structure in the soil together and improve soil looseness and permeability. This reduces soil erosion and improves soil nutrients. It activates potential nutrients in the soil, improves soil fertility, and promotes healthy crop growth.
The above is a brief introduction to the functions of microbial inoculants. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
