Description

Technical field

[0001] The invention relates to a granular composite microbial bacterial agent and a production method thereof, in particular to a composite microbial bacterial agent using medical stone as an adsorption carrier for microbial fermentation liquid, a production method and application thereof.

Background technique

[0002] Medical stone is a loose layered, veined, and lenticular structure formed by the original rock through alteration and weathering. It contains a variety of mineral elements that are beneficial to plant growth and development. It has a large specific surface area and has a porous and Sponge-like structure, at the same time, in these structures, tetrahedrons and octahedrons are arranged alternately, and Al in the lattice 3+ instead of Si 4+ As a result, excess negative charges appear, and additional cations are needed to balance the negative charges. These cations are loosely combined with the crystal lattice, so medical stone has good adsor...

Examples

Embodiment 1

[0051] 1. Strain fermentation

[0052] Bacillus subtilis (Bacillus subtilis), Bacillus megaterium (Bacillus megaterium), jelly-like Bacillus (Bacillus mucilaginosus), three strains were respectively subjected to slant culture, shaker expansion culture, seed tank fermentation and fermenter fermentation, After fermentation, the number of viable bacteria in the bacterial liquid reaches 3.5-4.5 billion / ml; (for strain fermentation, please refer to figure 1 )

[0053] 2. Bacterial liquid adsorption: the fermented bacterial liquid of a single strain is adsorbed with medical stone respectively in the adsorption stirring equipment, (the adsorption ratio is by Bacillus subtilis bacterial liquid: medical stone=1:5 (L / kg) , the adsorption ratio is by bacillus megaterium bacterium liquid: medical stone=1: 5 (L / kg), and the adsorption ratio is by jelly-like bacillus: medical stone=1: 5 (L / kg)), then stir Evenly, then mix and mix according to the ratio of 2:2:1; (for the preparation of po...

Embodiment 2

[0070] In the preparation of powdery composite microbial bacterial agent: the fermented bacterium liquid of single strain is adsorbed with medical stone respectively in the adsorption stirring equipment, (adsorption ratio is by Bacillus subtilis bacterium liquid: medical stone=1: 4( L / kg), the adsorption ratio is according to bacillus megaterium bacteria liquid: medical stone=1: 6 (L / kg), and the adsorption ratio is according to jelly-like bacillus: medical stone=1: 5 (L / kg) ), then stir evenly, then mix and mix according to the ratio of 2:3:1.
