Judging from the packaging The first is to check whether there is a microbial fertilizer registration certificate issued by the Ministry of Agriculture on the packaging. As bio-organic fertilizer is a fertilizer with special functions, product registration is conducted at the Microbiological Fertilizer Registration Center of the Ministry of Agriculture, and a fertilizer registration certificate is issued by the Ministry of Agriculture. Unlike compound fertilizers and common organic fertilizers, fertilizers are registered at the soil fertilization stations of the Agricultural Department of each province, and provincial-level fertilizer registration certificates are issued. The certificate number registration method is "microbial fertilizer (registration year) Pro word (number)" or "microbial fertilizer (registration year) standard (number)". The second is to check whether the number of valid live bacteria is marked on the packaging. If not, it is fake and shoddy products. The third is to check whether the packaging is marked with the date of production and the expiration date of the product. Because the special functional bacteria in biological organic fertilizers are alive and alive, the number of effective viable cells of special functional bacteria will continue to decrease with the extension of product preservation time. Be responsible for. The fourth is to see if there is a "NY884-2012 bio-organic fertilizer" standard on the packaging. The product implementation standards for bioorganic fertilizers and common organic fertilizers are different, the former being NY884-2012 (replacement of NY884-2004) and the latter being NY525-2012 (replacing previous NY525-2002). The fifth is to go to the website of the Ministry of Agriculture's Plant Management Division to make inquiries. For distributors, it is also possible to check the authenticity of bioorganic fertilizers from the product inspection report. The first is to check whether the product name, inspection basis, technical index, etc. on the inspection report of this batch of products are consistent with the packaging label. We must check the “supervision and inspection†report instead of the “consignment inspection†or the inspection report issued by the production company itself. See if the product is even The key role of bio-organic fertilizers is realized by microbial strains with special functions. If the product's water content is too high or too low, it is not conducive to the survival of the bacteria species. Therefore, it is relatively straightforward to judge from the moisture content. Grab a handful of fertilizer in the sunlight to see if the material is in the shade and throw it up to see if it is dust. Fertilizers are lumpy, or dry and ashy, all of which are substandard products. The carrier added in the bio-organic fertilizer should be a "package" composed of a variety of organic nutrients. Since it is a combination of various raw materials, it should be able to see traces of various raw materials under light. The composition of general products contains plant stalks (corn cobs, pods, etc.). A careful observation reveals the true ingredients of the raw materials, and some of the raw materials have special odors. See if the product is valid The key role of bio-organic fertilizers is achieved through the use of microbial strains with special functions. If these products do not have these special microbial strains or their content is not high and their abilities are not strong, the application effect can be imagined. Based on the experience of the laboratory, the author designed a simple identification method: In the first step, take a small amount of product and add a little tap water to make a dough. Put ice cubes in the refrigerator and disintegrate in the sun the next day. After repeated freezing and thawing at least three times, the bacteria in the fertilizer will freeze. When dead (cells freeze and form ice needles to puncture cells), the number will be greatly reduced, and the role played by the bacteria will be basically eliminated. In the second step, the original product and the two fertilizers and feces that are repeatedly frozen and thawed are in the same field or small pot, and the difference between the two is observed and observed regularly. If the difference is not obvious, it indicates that the bio-organic fertilizer product The ability of "special function strains" is not strong or sufficient, or even not.

How to distinguish the authenticity of biological organic fertilizer
Bio-organic fertilizers are decomposed by high temperature, have high nutrient content, are rich in beneficial bacteria, have high utilization rate and good effect, and are deeply favored by growers. However, due to its high selling price, some criminals have been driven by profits, and the production and sale of shoddy products have harmed the interests of legitimate enterprises and farmers. The effective living organisms of bio-organic fertilizer can not be seen and touched. From the aspect of product appearance, it is no different from common organic fertilizer.
