Abstract

A microbial protectant in a high-nutrient and high-activity chemical fertilizer-biological compound fertilizer and a preparation method thereof are related, belonging to the technical field of biological extracts. The microbial protectant mainly includes alginate oligosaccharide and tetrahydropyrimidine, with the other ingredients further including at least one of burdock oligosaccharide, chitosan oligosaccharide, amino acid, vegetable oil, fumaric acid, and citric acid. The microbial protectant can protect microorganisms from injury and death in extreme environments, such as a high-salt environment, has broad application prospects, and may be applied to the preparation of a high-activity microbial agent and the preparation of a high-nutrient chemical fertilizer-biological compound fertilizer.
