Bio-organic fertilizer is one of the most technologically advanced products in China's new type of fertilizer. According to the study, the key factor in the apparent effect of bio-organic fertilizer is "living + microbial bacteria with special functions," as fertilizer testing technology cannot keep up. Lead to market confusion, farmers can not tell. Design a set of identification methods for reference.
First, look at the packaging, is it standardized?
1. Product Registration Certificate: With the Ministry of Agriculture's Microbiological Fertilizer Registration Certificate No. (Note: Provincial Departments have no registration right), the correct method: "Microbial fertilizer (registration year) Pro word (number)" or "Microbial fertilizer (registration year ) Quasi-word (number) number";
2. Product technical indicators: The number of effective live bacteria (CFU) is ≥ 0.2 million/g. When registering, the Ministry of Agriculture only allows the labeling of ≥0.2 billion/g and 0.5 billion/g (Strict regulations, which must be required on the last day of the preservation period. Reach this number). In order to cater to the market, some companies have deliberately marked hundreds of billions of dollars. This is unscientific (the current technology is difficult to achieve) and is wrong.
3. Validity of the product: The national regulations are more than 6 months. With the extension of the storage time of bio-organic fertilizer products, the number of effective viable cells will continue to decline. It is irresponsible to mark the validity period too long.
Second, look at the material, is it even?
1. The product water content is too high or too low are not conducive to the species survival, judgment methods: grasping a handful of fertilizer observed in the sun, was a group of cloudy tide, dry ash are not normal products.
2. "Organic fertilizer nutrition" suitable for the growth of special functional bacteria species should be a package type, composed of a variety of organic nutrients (such as: fermented rapeseed, soybean flour, etc.), can see the traces of raw materials in the light, Or can smell the special smell of raw materials.
Third, see the effect, is it efficient?
Test method: add a small amount of water to transfer the bio-organic fertilizer into a lump and place it in ice in the refrigerator. Take it out the next day and dissolve it. Repeatedly three times, the bacteria in the fertilizer will be frozen or greatly reduced; this is Use it to compare with the original product and observe the difference in the same field, the difference is obviously good fertilizer, the difference is not obvious, indicating that the product has problems, it is recommended to give up.
