Aerobic bacterium-anaerobic bacterium composite microbe liquid inocula and preparation method thereof

Abstract

The invention discloses aerobic bacterium-anaerobic bacterium composite microbe liquid inocula and a preparation method thereof. The composite microbe liquid inocula comprise six liquid aerobic microbial agents and four liquid anaerobic microbial agents. The liquid aerobic microbial agents comprise a bacillus megaterium agent, a liquid Azotobacter chroococcum agent, a liquid bacillus mucilaginosus agent, a liquid streptomyces microflavus agent, a liquid bacillus subtilis agent and a liquid bacillus licheniformis agent. The liquid anaerobic microbial agents comprise liquid photosynthetic bacteria, a liquid lactobacillus plantarum agent, a liquid lactobacillus acidophilus agent and a liquid lactobacillus delbrueckii agent. The preparation method comprises culturing six types of aerobic bacteria to obtain six liquid aerobic microbial agents, culturing four types of anaerobic bacteria to obtain four mixed liquid anaerobic microbial agents, and injecting the six liquid aerobic microbial agents into the mixed liquid anaerobic microbial agents to obtain the composite microbe liquid inocula. The composite microbe liquid inocula have a quality guarantee period for one year or more at the normal temperature and have functions of nitrogen fixation, phosphate dissolution, potassium release, disease prevention and soil improvement.

Description

technical field [0001] The invention relates to the technical fields of agricultural microorganisms, ecological planting and microbial inoculum, in particular to a microbial liquid inoculum compounded with aerobic bacteria and anaerobic bacteria and a preparation method thereof. Background technique [0002] Due to the long-term excessive application of chemical fertilizers in my country, a large amount of soil compaction and acidification have been caused, the permeability of the soil, the ability to supply oxygen and the ability to maintain nutrient balance have been reduced, the beneficial microorganisms in the soil have decreased sharply, the residue of harmful substances and the growth of harmful microorganisms have been controlled. The absorption of nutrients and water by plant roots leads to poor growth and quality of crops, and various diseases are becoming more and more serious. At the same time, the increase of pesticide chemical residues in crops seriously threaten...
