Agricultural microbial agent (GB20287-2006) bio-organic fertilizer (NY884-2012) compound microbial fertilizer (NY/T798-2004)
1. Agricultural microbial agents (GB20287-2006)
On May 25, 2006, the State issued the GB20287-2006 "Agricultural Microbial Agent" standard, which was implemented on September 1, 2006.
1. Agricultural microbial agents (abbreviated as microbial products) are live bacteria that are directly used after one or more functional microorganisms (effective living bacteria) are added by industrial production, or are concentrated or adsorbed by carriers. Products. It is characterized by high number of bacteria, low dosage, use of various functional strains, and many varieties of products; wide application objects; parameters and indicators involving trial design and effect evaluation are also diverse.
9 varieties: rhizobium agent, nitrogen-fixing bacteria, phosphate-dissolving agent, silicate agent, photosynthetic bacteria, organic material decomposing agent (straw, feces, etc.), growth-promoting agent, complex bacteria, bacteria Rhizobium and bioremediation agents (degradation of pesticide residues, overcoming crop weight).
Scope of application: crops, soil, straw, pesticide residues, etc.
2, organic material decomposing agent / straw decomposing bacteria
Organic material decomposing agent: It can accelerate the decomposing microbial live preparations of various organic materials (crop straw, poultry manure, etc.). The technical index of the product is compounded with GB20287-2006 "Agricultural Microbial Inoculant" or Agricultural Industry Standard NY609-2002 "Organic Materials". Rotating agent.
Features: (1) The requirements of the strains in the product and their combinations should use functional strains that produce cellulase, hemicellulase and ligninase, often consisting of not less than 3 functional bacteria. (2) Evaluate the effect of the product by accelerating the decomposition of straw.
At present, the applicable range of organic material decomposing bacteria is divided into: crop straw (straw rotten bacteria), poultry manure (livestock and poultry manure decomposing bacteria) and both (crop straw, livestock and poultry manure).
2. Compound microbial fertilizer (NY/T798-2004)
The compound microorganism refers to a living fungus product which is compounded with nutrients (nitrogen, phosphorus, potassium, etc.) after being industrially produced and added. The total content of NPK in powder and granule products is not higher than 25%, in the range of 6% to 25%; liquid dosage form products are above 4%.
Features: Contains functional bacteria, nitrogen, phosphorus and potassium nutrients and organic carrier composition; balanced fertilizers for quick-acting and long-term supply needs.
3. Bio-organic fertilizer standard (NY884-2012)
Bio-organic fertilizer: a combination of specific functional microorganisms and a mixture of animal and plant residues (such as livestock manure, crop straw, etc.) and harmless treatment, and associated organic materials, both microbial and organic fertilizers. Effect of fertilizer.
Features: Add functional microorganisms in high-quality organic fertilizer (after decomposing).
