How to buy biological bacteria fertilizer

1. When purchasing biological bacterial fertilizer, it is necessary to pay attention to whether it has passed the effective period of the product. Generally, the biological bacterial fertilizer activity exceeding one year of production date will be significantly reduced.

2. Check whether there is a registration certificate of the Ministry of Agriculture. The products of regular manufacturers should be registered with the Ministry of Agriculture. The Provincial Department of Agriculture does not approve the registration of biological fungicide. The bio-fertilizers with *** province's agricultural fertilizer registration are counterfeit products.

3, prevent ordinary organic fertilizer posing biological bacteria. In addition, we must see whether the number of active bacteria indicated on the packaging bag meets the national regulations (the state requires that the number of viable bacteria in the biofungicide is ≥200 million/g, and granular ≥100 million/g. The composite microbial fertilizer and bio-organic fertilizer are effective. The number of viable cells was ≥20 million/g). Unqualified biofungus will never be purchased.

4, see the bacteria stored or used in the ground for a short period of time, will not grow hair, according to information on the introduction of bacteria long hair, because the microbial bacteria in a suitable environment for a large number of breeding, not a fertilizer problem, on the contrary It is precisely demonstrated that the microorganisms have high activity, good stress resistance, and they can survive in harsh environments.

5, smell the organic fertilizer used in the regular bacterial fertilizer fermentation should be aromatic, rather than bad odor.

6. When examining the quality of the fungus, one of the key indicators is stress resistance, that is, the viability of the strain under adverse conditions. It is recommended to choose a bacterial fertilizer that has a relatively strong scientific research strength and a regular bacterial fertilizer company to co-produce.
