In order to ensure the use of microbiological fertilizers, the following issues should be noted in the promotion and application of the majority of microbial fertilizer consumers:
1. Microbiological fertilizers without national registration certificates cannot be promoted. The State requires that microbial fertilizers must be inspected by the designated units of the Ministry of Agriculture and verified by regular field tests to fully prove their effectiveness, non-toxicity and harmlessness, and be approved by the Ministry of Agriculture for registration. In addition, they must be issued to a temporary registration certificate, and after three years of practical application, inspections will be reliable. Issue an official registration certificate. The official registration certificate is only valid for 5 years. Therefore, there is no problem with the quality of microbiological fertilizers that have not obtained a national registration certificate. Do not use them on a large scale.
2. Do not use microbial fertilizers that do not meet the standard number of live bacteria. The national regulations stipulate that the effective microbial count of microbial fertilizer bactericide should be ≥ 200 million ug/g, and the effective live bacteria count of large fertilizer should be ≥ 20 million ng/g, and there should be 40% surplus. If this standard is not met, the quality cannot meet the requirements.
3. Microbial fertilizers that are stored for longer than the expiration date should not be used. Due to the limitation of the technical level, at present, the effective bacteria of most microbial fertilizers in China are not more than one year old, so they must be used within the effective period as soon as possible. The sooner the better, the effect of expired microbial fertilizers will certainly be affected.
4. Storage conditions and methods of use must be strictly in accordance with regulations. Many effective microorganisms in microbial fertilizers are not resistant to high and low temperature and strong light, they are not resistant to strong acids and alkalis, and cannot be mixed with certain chemical fertilizers and fungicides. Therefore, the promotion and application of microbial fertilizers must be scientifically preserved and used according to the product specifications.
