The function of microbial fertilizer

Microbial fertilizer is actually a kind of bacterial agent, and this kind of microbial agent can provide one or more microbial communities that are beneficial to crop growth. as the microbial agents used in agriculture are often mixed with substrates with high organic matter content, such as peat, peat and organic fertilizers, it is customary to call microbial fertilizers as microbial fertilizers. Let's take a look at the role of microbial fertilizers.

Can increase output.

Practice has proved that the specific fertilizer effect of microbial fertilizer can not only provide nutrients for crops, but also secrete gibberellin, cytokinin, auxin and other active substances to stimulate, regulate and promote the growth and development of crops. it is beneficial to the increase of crop production.

Can improve the quality.

Microbial fertilizer can effectively improve the quality of agricultural products, the contents of protein, sugar, vitamins, amino acids and other beneficial ingredients of agricultural products harvested by microbial fertilizer are significantly increased, the grains and fruits are plump and smooth, and the color of vegetables and fruits is bright, delicious and good-looking, but also of high value. Some microbial fertilizer products can also reduce the accumulation of nitrate and improve the safety of agricultural products.

Enhance stress resistance

The effective bacteria in most microbial fertilizers have the function of secreting antibiotics and a variety of active enzymes, which can inhibit or kill pathogenic bacteria, reduce the occurrence of diseases and enhance the stress resistance of crops. for example, it can enhance the drought, cold, lodging, disease and saline-alkali resistance of crops, and effectively prevent the occurrence of crop physiological diseases.

Improve the utilization rate of chemical fertilizer

Most of the effective bacteria of microbial fertilizer can decompose organic matter in soil, and humic acid is formed during the decomposition of organic matter. Humic acid forms ammonium humic acid with nitrogen in soil, which can reduce the loss of nitrogen fertilizer. The effective bacteria for dissolving potassium and dissolving phosphorus can decompose and transform the solidified chemical potassium fertilizer and chemical phosphate fertilizer into available potassium and available phosphorus, improve their utilization rate, reduce the production input and reduce the waste of resources.

Improve soil nutrients

Effective bacteria of microbial fertilizer can promote the dissolution and release of insoluble nutrients in soil and improve the supply capacity of soil nutrients. The extracellular polysaccharides secreted by effective bacteria are the binders of soil aggregate structure, which can enhance soil aggregate structure, loosen soil, improve soil permeability and water and fertilizer conservation capacity, increase soil organic matter, activate potential nutrients in soil, and improve the supply of nutrients in soil.

Matters needing attention

1. Use it as soon as possible after opening the bag: other bacteria will invade after opening the bag, resulting in changes in the microbial flora and affecting the effect of use, so microbial fertilizer should be used as soon as possible after opening the bag to avoid long-term non-use.

2, avoid use under high temperature and drought: high temperature and drought weather, affect the reproduction and survival of microorganisms, can not play fully, the effect of fertilization will be reduced.

3. Avoid mixed use of uncooked farm manure: immature organic compost will produce a lot of heat in the process of composting, and microorganisms will be killed at high temperature, affecting the fertility of microbial fertilizer. At the same time, we should also pay attention to avoid mixing with acid-base fertilizers.

4. Avoid using pesticides at the same time: if both are used at the same time, the properties of chemical fertilizers and pesticides will inhibit the growth and reproduction of microorganisms and, in serious cases, kill microorganisms.
