Bio-organic fertilizers are rotten at high temperature, have high nutrient content, are rich in beneficial bacteria groups, have high utilization rate and good effect, and are favored by fruit farmers. The effective live bacteria of biological organic fertilizer can not be seen or touched. From the appearance of the product, it is no different from ordinary organic fertilizer. How to identify the authenticity?
Judging from the outer packaging 1. Check whether there is a microbial fertilizer registration certificate issued by the Ministry of Agriculture. The registration of bio-organic fertilizer products is carried out at the Microbial Fertilizer Registration Center of the Ministry of Agriculture, and the Ministry of Agriculture issues a fertilizer registration certificate. The registration method of the certificate number is "microbiological fertilizer (registration year) Linzi (number) number" or "microbiological fertilizer (registration year) Zhunzi (number) number". 2. Check whether the effective live bacteria number is marked on the package. If not, they are fake and shoddy products. 3. Check whether the package is marked with the production date and the expiration date. Because the special functional bacteria in bio-organic fertilizers are live and alive, the product's expiration date is too long to be responsible to the user. 4. You can go to the relevant website of the Department of Planting Management of the Ministry of Agriculture for inquiries.
See if the product is homogeneous. If the water content is too high or too low, it is not conducive to the survival of the bacteria. Judging method: Grab a fertilizer and observe it in the sun. The "organic fertilizer nutrition" suitable for the growth of special functional bacteria should be a package type, composed of a variety of organic nutrients (such as: fermented vegetable meal, soybean meal, etc.). The traces of raw materials can be seen in the light, Smell the special smell of raw materials.
At first glance, in addition to two bubbles and three fires, some user experience can also be used for reference. A look: High-quality bio-organic fertilizer generally uses high-quality chicken manure as raw materials, with high nutrients, relatively loose, and dark brown in color. Poor organic fertilizers are usually black and not loose enough. Second bubble: Authentic granular organic fertilizer will be dissolved in water in a short time, the color is gray and black, but there are no impurities; false ones will have a lot of impurities that are not soluble in water. Mizuma: Put a small amount of organic fertilizer on an iron plate and put it on a fire source. In a short time, the real product will smoke, coke, and there will be few residues; fake ones will leave a lot of residues.
