is a kind of "bacteria + fertilizer", because on the one hand, bacterial fertilizer contains "organic matter, nitrogen, phosphorus and potassium" necessary for crop growth, on the other hand, the product contains a large number of beneficial microorganisms, beneficial microorganisms and bacteria multiply in the soil, playing a role in improving soil and preventing diseases. So, what is the effect of bacterial fertilizer? How can we effectively use bacterial fertilizer? Is there anything that needs attention? Let us understand together.

What is the role of bacterial fertilizer?

Because biomass fertilizer contains a large number of organisms, the biological activity in biomass fertilizer can not only improve the soil structure, increase the content of various elements in the soil, but also bring the effect of potassium, phosphorus release and nitrogen fixation. After the biological fertilizer is applied to the soil, the organism quickly forms a cluster advantage, decomposing the nitrogen, phosphorus and potassium that are fixed in the soil and cannot be absorbed and utilized by plants, and fixing the free nitrogen in the air for plants to absorb and utilize. In addition, biological fertilizer can also help crops germinate and mature early, and can produce stress resistance in crops, which can effectively resist disease, drought and lodging. Microbial fertilizer itself does not contain toxins and residues, can be used in the field for a long time, can effectively dissolve the heavy metal residues after sewage irrigation, and purify the environment.

Precautions for Using Bacterial Fertilizer:

1. Mixing is exquisite.

biological bacterial fertilizer is completely rotten, not easy to be directly mixed with chemical fertilizer, and easy to be mixed with sulfur-containing chemical fertilizer and plant ash. Its effect is better than that of biological bacterial fertilizer alone. Special attention should not be mixed with sulfur-containing chemical fertilizer and plant ash, because this fertilizer is easy to kill beneficial bacteria in bacterial fertilizer. Use nutrient soil to disinfect the soil or vegetables in the greenhouse, it takes at least 10 to 15 days to get biological fertilizer, remember not to use biological fertilizer to disinfect the soil. Bacterial fertilizer cannot be applied simultaneously with fungicides, herbicides and herbicides. Generally speaking, the fungicide will not be applied again until 48 hours after the application of bacterial fertilizer. Do not mix with the mixed fungicide.

2. have certain requirements for soil quality.

The utilization effect is related to the soil conditions of the biological fertilizer. The soil is too dry or too wet to the reproduction of biological fertilizer, soil moisture should be about 60%.

3. sun conditions are also important.

microbial fertilizer is very sensitive to sunlight, storage or use should try to avoid direct exposure to strong light, generally do not use the ground, can be applied in cloudy days or early morning, evening in the soil. Just spray evenly on the leaf backs of the plants.

4. temperature change.

Apply bacterial fertilizer in the range of 22 ℃-35 ℃, preferably below 5 ℃, and the effect above 40 ℃ is poor. It is not suitable to apply crop fields under high temperature, low temperature and drought conditions. Among them, 60%-70% of the soil is suitable for nitrogen-fixing bacteria fertilizer.

5. dosage.

For many years, due to the application of chemical fertilizers into too many fields, the application amount of chemical fertilizers and organic fertilizers cannot be greatly reduced when applying biological bacterial fertilizers. Because crops rely on chemical fertilizers, biological bacterial fertilizers cannot be used instead of nitrogen fertilizers at once. Therefore, its replacement amount should reach 30%,40%,60%, phosphorus and potassium fertilizer can only be used to supplement, not reduce, or used to replace.

and above are the functions of

bacterial fertilizer

and what should be paid attention to when using it. I hope it will help you!
