Several problems that should be paid attention to in the promotion of microbial fertilizer

Microbial fertilizers provide beneficial microorganisms such as nitrogen fixation, phosphorus solubilization, and potassium release. These living microorganisms can grow and multiply in the rhizosphere of plants, which can bring several benefits: First, through the life activities of these beneficial microorganisms, fixed transformation The molecular nitrogen that can not be used in the air is the combined nitrogen, and the compound phosphorus and potassium that cannot be utilized in the soil are analyzed as phosphorus and potassium in the available state, and more than 10 kinds of medium and trace elements in the soil can be analyzed. The second is to secrete auxin, cytokinin, gibberellin, citric acid and other plant hormones through the life activities of these beneficial microorganisms, promote crop growth, regulate crop metabolism, and build high-quality products according to genetic code. The third is to multiply the beneficial microorganisms in the rhizosphere, produce a large amount of mucopolysaccharides, combine with the mucus secreted by the plants and mineral colloids, organic colloids to form a soil aggregate structure, and enhance soil fertility and water retention capacity. Good quality microbial fertilizer can promote crop growth, improve soil structure, improve the quality of crop products and improve the disease prevention and disease resistance of crops, thus increasing production and income.
Several problems should be paid attention to in promoting the application of microbial fertilizer
1. Microbial fertilizers that do not have a national registration certificate cannot be promoted. The state stipulates that microbial fertilizers must be inspected by the designated units of the Ministry of Agriculture and regular field trials, fully proving that their benefits, non-toxic, and harmless are approved by the Ministry of Agriculture, and are issued to the temporary registration certificate. After three years of practical application, the test is reliable. Issue an official registration certificate. The official registration certificate is valid for only 5 years. Therefore, microbial fertilizers that do not have a national registration certificate may have problems in quality, and should not be widely used.
2. Do not use microbial fertilizers with a valid viable count that does not meet the standard. The state stipulates that the effective viable count of microbial fertilizers is ≥200 million/g, the effective viable count of Dafei is ≥20 million/g, and there should be a 40% surplus. If this standard is not met, the quality will not meet the requirements.
3. Microbial fertilizers with storage time exceeding the expiration date should not be used. Due to the limitation of technical level, the effective bacteria survival time of most microbial fertilizers in China is less than one year, so it must be used as soon as possible within the validity period. The sooner the better, the effect of expired microbial fertilizer will definitely have an impact.
4. Storage conditions and methods of use shall be strictly in accordance with regulations. Many effective live bacteria in microbial fertilizers are not resistant to high and low temperature and strong light, are not resistant to strong acid and alkali, and cannot be mixed with certain fertilizers and fungicides. Therefore, the promotion and application of microbial fertilizers must be scientifically preserved and used according to the product specifications.
