The function and prospect of probiotics in microbial fertilizer

Microbial fertilizer

Microbial fertilizer is also called the biological fertilizer, agricultural production is used in a kind of fertilizer products, with the nature of chemical fertilizer, organic fertilizer, green manure, it is the use of microbial life activities and the role of metabolites, improve crop nutrient supply, to provide crop nutrients, growth material, control its growth, improve yield and quality, reduce fertilizer use, The purpose of improving soil fertility.

Using microbial fertilizer can improve the microecological environment of crop rhizosphere. Through the synthesis or decomposition of microbial life activities, the soil hardening and poor physical and chemical properties caused by long-term application of chemical fertilizers can be improved, so that the rhizosphere soil of crops can retain water and fertilizer with good permeability, and the root system of crops can be developed and the drought-resistant ability can be enhanced. Moreover, the dominant population of beneficial bacteria in crop rhizosphere formed by many beneficial microbial populations can antagonize the relatively weak population of pathogenic bacteria, destroy or weaken pathogenic bacteria, and thus reduce or avoid crop disease.

Microbial fertilizers have more advantages than chemical fertilizers in improving crop quality. The results of many studies and experiments have proved that microbial fertilizer can balance the relationship between nutrient supply and improve the quality of agricultural products. Reasonable and correct application of microbial fertilizer can improve the appearance quality of agricultural products, improve the storage and transportation performance, optimize the flavor and taste, and increase the accumulation of dry matter.

Produces and assists crops to absorb nutrients, improve soil fertility, improve fertilizer efficiency and reduce the amount of fertilizer used. Through specific microbial populations in the microbial fertilizer nitrogen fixation, phosphate-solubilizing, releasing, and other functions, and microorganism on crop root system grows, can promote the absorption on the one hand, on the other hand, the life of the microbial population activity, can make a lot of humus, improve soil physical and chemical property, avoid the loss of a large number of fixed and fertilizers in soil, the, thus improve the fertilizer effect. At the same time, due to the decomposition and synthesis of microorganisms (such as nitrogen fixation, etc.), the fertilizer supply of the native soil to the rhizosphere can be increased, and the amount of chemical fertilizer can be reduced, thus increasing the efficiency and saving energy.

Compared with chemical fertilizer, microbial fertilizer consumes less energy during production and has lower production cost. Moreover, due to the use of microbial fertilizer, the utilization rate of chemical fertilizer can be increased by at least 50%. From the perspective of the current use of chemical fertilizer in agricultural production, it is an amazing economic account whether it is the saving of production cost in micro agricultural production or the saving of national energy in macro.

The use of microbial fertilizer can promote the decomposition and utilization of agricultural waste (crop straw, animal manure, animal product waste, etc.) and urban refuse; It can be made into microorganism organic compound and compost to realize waste utilization and provide high quality fertilizer with low cost for agriculture.

Small amount of microbial fertilizer, labor and festival, itself non-toxic and harmless, no environmental pollution problem; It can reduce the amount of pesticide and simplify the operation procedure of farming because of its promoting effect. The use of chemical fertilizers causes serious environmental pollution problems.
