Biological fertilizer referred to as "bacteria fertilizer" is a microbial life activities lead to crops to obtain a specific fertilizer effect of a product. It uses the life activities and metabolites of microorganisms to improve crop nutrient supply, provide nutrient elements for crops, grow substances, increase growth, enhance stress resistance, improve yield, improve quality, reduce fertilizer use and improve soil fertility. Improve the crop nutrition conditions, such as nitrogen in fixed air, participate in the transformation of nutrients, promote crop nutrient absorption; secrete all kinds of hormones to stimulate crop root development, inhibit the activities of harmful micro-organisms. In the application of vegetables, can prevent the dead trees, reduce the disease, improve the soil, the lifting of salt and other special effects, and welcomed by farmers.
Types of microbial fertilizers
(1) microbial agents. Refers to the target micro-organisms (effective bacteria) after industrial production and production of activated bacteria made of the preparation, it has a direct or ask to improve the soil, to restore soil fertility, to maintain rhizosphere microbial flora balance, degradation of toxic and harmful substances and other effects; In the agricultural production, through the activities of microorganisms contained therein, increase the supply of plant nutrients or promote plant growth, improve the quality of agricultural products and agricultural ecological environment. Microbial agents according to the type of microbial contained or functional characteristics can be divided into rhizobia fungicides, azotobacter bacteria, phosphorus microbial agents, silicate microbial agents, photosynthetic bacteria agents, organic materials, Bacteria agents, mycorrhizal fungi, bioremediation agents and so on. Shandong Yitai Biotechnology Co., Ltd. specializes in the field of modern agriculture, aquaculture and environmental management, mainly engaged in research and development, production and sales of compound micro-ecological agents. The company uses the self-breeding of fine strains for fermentation production, the bacteria stout, vigorous, spore neat, with a strong environmental adaptability, easy processing and preservation.
(2) composite microbial fertilizer. Refers to the combination of specific microorganisms and nutrients, can provide, maintain or improve plant nutrition, improve the yield of agricultural products or improve the quality of agricultural products in vivo microbial products.
(N + P2O5 + K2O, trace elements, biological protein, organic matter, activated carbon, active calcium, humic acid, etc.), which is a microbial agent (microbial agent), which is a microbial agent The most obvious difference between microbial fertilizers. Microbial bacteria inside the bacteria of high purity, effective viable count of ≥ 5 billion / gram. Microbial fertilizer is generally effective viable count ≥ 20 million / g.
(3) bio-organic fertilizer. Refers to a specific functional microorganisms and mainly with animal and plant residues (such as livestock and poultry manure, crop stalks, etc.) as raw materials and harmless treatment, decomposition of organic materials combined with a combination of microbial fertilizer and organic fertilizer effect of fertilizer The Played a biological bacteria "solution" role, itself and the supply of a variety of nutrition, biological bacteria is a major application of progress
