Look at the registration number to distinguish between true and false
According to the current fertilizer management regulations, the compound fertilizer, water-soluble fertilizer, organic fertilizer, microbial fertilizer, etc. must be examined by the management department before production, and the registration certificate number can be used for production. The registration certificate number is four digits. If there is no registration certificate number or registration certificate number on the package label that is more or less than four digits, it is a product that has not obtained the fertilizer registration certificate. In addition, if two or more different types of fertilizer products or the same type of products are marked with different nutrient contents, the same registration number is used, at least one of which is a counterfeit registration number, and the farmers' friends must be cautious when choosing.
Look at nutrients to identify true and false
The nutrient content of fertilizer products generally does not exceed 60%, and more than 60% is generally problematic.
A large amount of elements, medium and trace elements, organic matter and other nutrients are marked together on the packaging label of a certain fertilizer; the three elements of nitrogen, phosphorus and potassium fertilizers and medium elements (calcium, magnesium, silicon, etc.) are marked on the compound fertilizer packaging label. The trace elements (zinc, boron, iron, etc.) nutrients are added together; the organic-inorganic compound fertilizer packaging label indicates that the organic matter content and the total nutrients of nitrogen, phosphorus and potassium are together and are generally problematic.
See how many functions are true and false
The function of the fertilizer is to provide nutrients for crop growth or to improve soil physical and chemical properties. If the fertilizer product packaging label indicates a variety of functions, be careful when purchasing. If it is marked with "preservation of flowers and fruit, swelling and coloring", it is likely to add hormones; if it is marked with "detonation of fertilizer nuclear power", "addition of zinc long-acting corn to a shell", there are suspicions of exaggerated propaganda, which are unauthorized changes. Fertilizer registration packaging identification behavior. The packaging label is marked with exaggerated and ambiguous words such as “××肥王â€, “all elements××fertilizerâ€, “international advanced level†and “nano-fertilizerâ€. These fertilizers are mostly irregular or non-standard manufacturers. It is more prudent to buy.
See if the standard is true or false
Some of the fertilizers produced by irregular or non-standard manufacturers are generally not standardized. For example, the same fertilizer product is marked with multiple product names, both “organic fertilizer†and “organic-inorganic compound fertilizerâ€, and “complex fertilizerâ€; for example, “chlorine†fertilizer, not “ Chlorine is indicated in the nutrient site, but is indicated in the hard-to-find parts. The font used is very small and may cause serious damage to crop growth after use.
