Abstract

The invention discloses a new-generation full-element chelated-state food-grade liquid bacterial fertilizer and a preparation method thereof, relates to an organic fertilizer containing bacterial cultures or hyphae, and aims at providing a liquid bacterial fertilizer and a preparation method thereof. Multiple high-salt-resistant strains are reasonably matched and cooperate with multiple chelating solutions, and therefore after the bacterial fertilizer is applied, effective ingredients in the bacterial fertilizer can be efficiently utilized for a long term. The new-generation full-element chelated-state food-grade liquid bacterial fertilizer is prepared from 4-6 parts of composite microbial strains, 4-5 parts of molasses, 0.4-0.6 part of bran, 0.05-0.1 part of carbamide, 0.05-0.1 part of sodium chloride, 0.01-0.02 part of tea leaves, 7-9 parts of a composite sugar alcohol-trace element chelating solution, 20-26 parts of an ammonium polyphosphate-nitrogen-phosphorus-potassium chelating solution, 3-5 parts of an organic acid-medium and trace element chelating solution and 45-50 parts of water.
