What kinds of bacteria for biological bacterial fertilizers determine how the bacteria and bacteria are qualified?
Bio-organic fertilizer is high-temperature decomposed, with high nutrient content, rich in beneficial bacteria, high utilization rate and good effect, which is favored by growers. However, due to its high selling price, some lawless elements are driven by interests, making and selling fake and inferior products, which harms the interests of legitimate legal enterprises and farmers. The effective living bacteria of bio-organic fertilizer can not be seen and 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
First, check whether there is a microbial fertilizer registration certificate issued by the Ministry of Agriculture on the packaging. Since bio-organic fertilizer is a fertilizer with special functions, the product registration is carried out at the microbial fertilizer registration center of the Ministry of Agriculture, and the fertilizer registration certificate is issued by the Ministry of Agriculture.
Unlike compound fertilizers and common organic fertilizers, fertilizer registration is carried out in the soil and fertilizer stations of the agricultural departments of the provinces, and provincial fertilizer registration certificates are issued. The registration method of the license number is “microbial fertilizer (registration year) Pro word (number) number†or “microbial fertilizer (registration year) quasi-word (number) numberâ€.
The second is to check whether the number of valid viable bacteria is marked on the package. If not, it is a fake and shoddy product.
The third is to check whether the product is marked with the product production date and expiration date. Because the special functional bacteria in bio-organic fertilizers are live and animate, as the storage time of the products is prolonged, the number of effective viable bacteria of special functional strains will continue to decrease, so the product validity period is too long to be Be responsible for.
Fourth, you can go to the relevant website of the Plantation Management Department of the Ministry of Agriculture for inquiries. For dealers, you can also check the authenticity of bio-organic fertilizer from the product inspection report. The first is to check whether the product name, inspection basis, technical indicators, etc. of the batch product inspection report are consistent with the packaging label. Be sure to check the “supervision inspection†report instead of the “commission inspection†or the inspection report issued by the manufacturer itself.
See if the product is even
The key role of bio-organic fertilizers is achieved by microbial strains with special functions. If the water content of the product is too high or too low, it is not conducive to the survival of the strains. Therefore, it is relatively straightforward to judge from the water content.
See if the product is valid
The key role of bio-organic fertilizers is achieved through microbial strains with special functions. If these products do not have these special-purpose microbial strains or their content is not high and their ability is not strong, the application effect can be imagined.
Microbial fertilizers generally do not contain the nutrients needed for crop growth. Instead, they improve the nutrient conditions of crops through the life activities of microorganisms, such as fixing nitrogen in the air, participating in the conversion of nutrients, promoting the absorption of nutrients by crops, and secreting each The hormone stimulates the root development of the crop and inhibits the activity of harmful microorganisms to achieve the purpose of promoting crop growth.
There are many types of microbial fertilizers, which are classified into bacterial fertilizers, actinomycetes (such as antibiotics), fungal fertilizers (such as mycorrhizal fungi), nitrogen-fixing cyanobacteria, etc. according to the specific microbial species in their products. According to their different functions, microbial fertilizers can be divided into five categories:
(1) Fertilizers with nitrogen fixation, including rhizobial fertilizers, nitrogen-fixing bacteria fertilizers, and nitrogen-fixing cyanobacteria fertilizers.
(2) Fertilizers that decompose soil organic matter, including organophosphorus bacterial fertilizers and compound bacterial fertilizers.
(3) The bacterial fertilizer that decomposes the insoluble minerals in the soil, including silicate bacterial fertilizer and inorganic phosphorus bacterial fertilizer.
(4) Fertilizers that promote the use of crops for soil nutrients, including mycorrhizal fertilizers.
(5) Fertilizers that are resistant to disease and stimulate crop growth, including antibiotic fertilizers and strains.
