The invention discloses a preparation method and a product of a garlic straw returning crop root rot prevention agent. The raw material is based on agricultural waste garlic straw, and then the anti-root rot factor is extracted, the garlic straw is carbonized, the carbonaceous nutrient solution is extracted, and the Carbon-based bacteria-carrying and other technologies are finally combined with the extracted nutrient components, the bacteria-carrying carbon base and the clay matrix decomposed by garlic roots. The invention can reduce the incidence of root rot by 90.23% while realizing the return of garlic straw waste to the field, and reduce the death rate of plants by 77.27% after the disease occurs. |
