Functionalized carbon-based organic fertilizer and preparation method thereof
By preparing functionalized carbon-based organic fertilizer, specific biocontrol strains are combined with porous biochar carriers and organic fertilizer matrix, solving the problems of low survival rate and unstable control efficacy of microbial fertilizers in soil. This achieves highly efficient control of tobacco black shank and bacterial wilt, and significantly improves the survival ability and control efficacy of functional bacteria.

AI Technical Summary
Existing microbial fertilizers have low survival rates and are difficult to colonize in soil, resulting in unstable preventive effects. They also lack precise compounding solutions for specific diseases and regional characteristics. Traditional organic fertilizer substrates have limited protective effects on microorganisms, leading to limited control effects.
Functionalized carbon-based organic fertilizer is prepared by screening specific preserved biocontrol strains and combining them with porous biochar carriers and organic fertilizer matrix. During the preparation process, the biocontrol strains are uniformly attached to the carbon-based carrier. Combined with the physical protection and nutrient slow-release effect of biochar, functionalized carbon-based organic fertilizer is prepared.
It has achieved highly efficient control of tobacco black shank and bacterial wilt, with a control efficacy of over 73%. It has significantly improved the survival ability of functional bacteria in complex soil environments, regulated the rhizosphere microecology, induced systemic resistance in tobacco, and replaced chemical pesticides.
