Currently, microbial fertilizers include microbial inoculants (microbial inoculants), compound microbial fertilizers (bacterial fertilizers), and biological organic fertilizers (bacterial fertilizers). In the process of use, microbial fertilizers have significant effects on improving soil fertility, preventing and controlling diseases, and improving quality. However, some friends report that the effect is unstable. The effects of the same batch of varieties are very different under different crops, different periods, and different dosages. . The investigation found that there are many misunderstandings in the use of this type of fertilizer.
Misunderstanding 1: The type is chaotic, and it is not clear whether the bacterial agent or the bacterial fertilizer is used
Agricultural microbial inoculants refer to live bacteria preparations made by industrial production and expansion of target microorganisms (beneficial bacteria); microbial fertilizers include compound microbial fertilizers and bio-organic fertilizers. The main animal and plant residues (such as livestock and poultry manure, crop straws, etc.) are living bacteria products compounded with organic materials from the source and harmless treatment.
The most important difference between bacterial agent and bacterial fertilizer lies in the content of nutrients and organic materials in the product. In use, it is necessary to select the right product according to actual needs.
Misunderstanding 2: Think that the more types of bacteria in a product, the greater the number of bacteria, the better
The use effect of the compound bacterial agent will be affected by the growth habit of different bacterial species, and blindly compounding can easily cause antagonism between bacterial species and affect the effect. After the product is used, only live bacteria work, so the standard of bacteria measurement is "effective viable cell number (CFU)". The larger the effective viable bacteria number, the better the effect.
In addition, the purity of the bacteria is also very important, and the application will be affected when the number of fungi and the rate of fungi in the product exceeds the standard. The few unqualified products on the market contain pathogenic bacteria, which not only cannot repair the soil, but also cause diseases.
Misunderstanding 3: One-time use in one season is fine, and one-time use can last for many years
Some microbial strains will multiply after being applied to the soil. When the number reaches a certain level, they will become the dominant flora. However, changes in the external environment will cause the death of beneficial bacteria, which will affect the status of the beneficial bacteria in the soil microbial system. Its status requires the use of microbial fertilizers to supplement beneficial bacteria during the growth period of crops.
Misunderstanding 4: Do not pay attention to the types of bacteria, think that one type of bacteria can solve multiple problems
A small number of users lack the awareness of symptomatic use of bacteria. When purchasing products, they only pay attention to whether they contain bacteria, but do not pay attention to the types of bacteria. After using the incorrect bacteria varieties, the desired purpose cannot be achieved.
For the microbial species registered with the Ministry of Agriculture at this stage, they have different functions. It is necessary to select symptomatic products based on the needs, the characteristics of the bacteria, and the functions of the bacteria.
