What are the common types of microbial fertilizers? How to use it correctly?

As we all know, if there is no microbial composition in the soil, it is equivalent to no activity and productivity. However, the most common agricultural phenomenon in China is serious cropping and excessive chemical fertilizer index, resulting in the destruction of a large number of beneficial microflora in the soil. Therefore, the application of microbial fertilizer is the most direct and effective way to improve soil quality and soil biological fertility, so as to increase crop income. So what are the common types of microbial fertilizers? How to use it correctly? Let's get to know it.

Common types of microbial fertilizers

1. Nine bacterial agents

Rhizobium agents, nitrogen-fixing agents, phosphorus-solubilizing agents, silicate agents, mycorrhizal agents, photosynthetic agents, organic material ripening agents, compound agents and soil remediation agents.

Function: microbial agents can directly or indirectly improve soil, restore soil fertility, maintain the balance of rhizosphere microflora, degrade toxic and harmful substances and so on.

2. Two bacterial fertilizers

① compound microbial fertilizer is the first fertilizer to solve soil consolidation, repair and recuperate soil, improve the utilization rate of chemical fertilizer and improve fruit quality and yield.

② bio-organic fertilizer: a kind of fertilizer with the effect of both microbial fertilizer and organic fertilizer, which is mainly derived from animal and plant residues and treated with harmless and decomposed organic materials.

Application method of microbial fertilizer

1. Microbial agents

It is mainly used as base fertilizer, topdressing and seedling fertilizer. The general dosage of solid bacterial agent is about 2 kg / mu, which is evenly mixed with 40-60 kg organic fertilizer and used. When raising crop seedlings, the solid bacterial agent can be mixed into the nutritious soil, mixed and then loaded into the nutrition bowl to raise seedlings; it can also be diluted 10-20 times to mix seeds, dip in roots, spray roots, or 500 times diluted solution for foliar spraying.

2. Compound microbial fertilizer

Used as base fertilizer 10-20 kg / mu, applied together with organic fertilizer or farm manure; topdressing 10-20 kg / mu, topdressing during crop growth period; foliar spraying, diluted 500 times.

3. Bio-organic fertilizer

As base fertilizer 100 kg / mu, applied together with farm fertilizer; topdressing is about 7-10 days earlier than chemical fertilizer, which can be applied with reference to the amount of chemical fertilizer.

The above is the introduction of the types and methods of use of microbial fertilizers, it should be noted that microbial fertilizers have relatively strict requirements on soil conditions, and should be avoided to be used at the same time with pesticides. And we just need to use it according to the correct instructions of different varieties.
