How to use microbial fertilizer rationally
The exertion of microbial fertilizers is affected not only by its own factors such as the type and amount of effective microorganisms contained in fertilizers, but also by other factors such as soil moisture, organic matter, pH, etc. Fertilizer selection and application should pay attention to rationality. So far, there are only 100 kinds of microbial fertilizers that have been approved by the State to register, and actually more than 2,000 manufacturers have been produced. Therefore, microbial fertilizers sold on the market are mixed. Farmers' friends lack relevant knowledge and detection methods. Therefore, when selecting microbial fertilizers, they should consult the local units engaged in soil fertilizers (earth-fertilizer stations, agricultural institutes), and pay particular attention to the following issues: 1. Microbiological fertilizers that do not have a national registration permit cannot be promoted by the State. Microbiological fertilizers must be inspected by the designated units of the Ministry of Agriculture and regular field tests, fully demonstrating their effectiveness, non-toxicity and harmlessness, and they must be approved by the Ministry of Agriculture for registration, and they must be issued to temporary registration certificates. , After three years of practical application of the test is reliable and then issued to the 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. The number of microorganisms that do not meet the standard for effective viable count shall not be the same as the national standard for the number of viable microbial cells in the microbial organism or not more than 200 million g/g, and the effective live bacterial efficiency of bio-organic fertilizer shall be ≥20 million g/g, and there shall be 40% surplus. If this standard is not met, the quality cannot meet the requirements. 3. Microbial fertilizers with storage time exceeding the valid period should not be used due to the limitation of the technical level. At present, the effective bacteria of most microbial fertilizers in our country have survived for less than one year. Therefore, it must be used as soon as possible within the validity period. The sooner the better, the expired microbial fertilizer will definitely affect its fertilizer efficiency. 4. Storage conditions and methods of use must be strictly in accordance with regulations. Many effective live bacteria in microbial fertilizers are not resistant to high temperatures, low temperatures, and strong light. They are not resistant to strong acids and bases and cannot be mixed with certain chemical fertilizers and fungicides. Therefore, the promotion and application of microbial fertilizers must be scientifically preserved and used in accordance with the product specifications. 5. Application method Microbial fertilizer should be applied directly below the root of the crop. Do not leave the roots too far. Cover the soil and do not let the sun shine directly on the fungus fertilizer. Microbial fertilizer is mainly used as a base fertilizer and should not be sprayed on foliage. The use of microbial fertilizers cannot be used. Instead of using fertilizer. 6. Anshan's custody of unused microbial fertilizers should be properly kept to prevent the spread of bacteria in microbial fertilizers.
