Biological bacterial fertilizer and preparation method thereof

Abstract

The invention discloses a biological bacterial fertilizer, which is prepared from the following raw materials in parts by weight: 40 to 60 parts of amino acid, 4 to 6 parts of brown sugar, 20 to 30 parts of bacillus subtilis, 5 to 15 parts of photosynthetic bacteria, 1 to 3 parts of magnesium sulfate, 80 to 120 parts of fish protein powder and 600 to 1000 parts of water. The photosynthetic bacteria in the biological bacterial fertilizer can perform photosynthesis, photosynthesis is performed by utilizing light energy, meanwhile, the soil structure can be improved, the soil fertility can be improved, and crop growth can be promoted; and bacillus subtilis not only can inhibit phytopathogen, but also can induce the disease resistance mechanism of plants so as to enhance the disease resistance of plants, and the biological bacterial fertilizer obtained by mixed fermentation of photosynthetic bacteria, bacillus subtilis, amino acid, brown sugar, magnesium sulfate and fish protein powder can effectively reduce the usage amount of a nitrogen phosphorus potassium fertilizer. and the yield and the quality of products are improved at the same time.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological bacterial fertilizer and a preparation method thereof. Background technique [0002] At present, most agricultural crops rely on chemical fertilizers and chemical agents to increase production. Long-term use destroys the chemical balance of the natural microbial community in the soil, unbalances the physical and chemical conditions of the soil, and severely attenuates the natural fertility of the soil. Applying more chemical fertilizers to maintain high yields increases costs, and long-term irrational application of chemical fertilizers and pesticides leads to waste of resources and increased production costs, serious environmental pollution, and decline in the quality of agricultural products. [0003] Biological bacterial fertilizer is the main variety of new fertilizers in the 21st century. It is a specific fertilizer containing living microorganisms. It is ba...
