Beware of three misunderstandings when applying microbial fertilizers

Misunderstanding one thinks that microbial inoculum is equal to microbial fertilizer

Microbial inoculants refer to the live bacteria preparations made from the fermentation broth that adsorbs the bacteria by using porous materials such as peat charcoal and vermiculite as adsorbents after the target microorganisms (effective bacteria) are expanded through industrial production. Its storage environment and use The time limit is relatively strict. Once the live bacteria expire, the product is basically of no use value.

There are two common types of microbial fertilizers: bio-organic fertilizer and compound microbial fertilizer. Even if the viable microbial fertilizer is invalid, the product can still be used as a general organic fertilizer or compound fertilizer.

Misunderstanding 2

It is believed that the more effective live bacteria, the better

Don't blindly pursue the high bacterial content of a single strain when applying microbial fertilizers. Beneficial bacteria need to cooperate and grow cooperatively with other bacteria in the soil to play a huge role.

Of course, qualified microbial fertilizers have basic requirements for the effective number of viable bacteria. The bio-organic fertilizer standard stipulates that the effective live bacteria content is not less than 20 million/g, and the organic matter content is not less than 40%; the microbial inoculant standard stipulates that the effective live bacteria number is not less than 200 million/g (ml), and the particle type is not less than 100 million/g; the compound microbial fertilizer standard stipulates that the effective number of viable bacteria is 50 million/ml for liquid and 20 million/g for solid.

Misunderstanding three

The growth of soil hair after application of microbial fertilizer is related to the quality of the fertilizer

In fact, most of the white hairs or hyphae appearing in the soil are miscellaneous fungi, and some are slime fungi, while small mushrooms are mostly Coprinus fungi. These fungi like to live in humid places, most of them are saprophytes, and the temperature requirements are not very strict. Generally, they can grow at 2℃~33℃. Therefore, it cannot be used to judge the quality of microorganisms.
