Abstract

The invention discloses a preparation method of an algae amino acid microbial fertilizer, which comprises the following steps: (1) crushing algae, adding water and a fermentation promoter, sterilizing for 20-40 minutes at the temperature of 120-125 DEG C, reducing the temperature to room temperature, adding a composite strain to ferment the mixed solution for 3-5 days at 25-35 DEG C, and adjusting the pH value to 7.2-8.0; and (2) sequentially adding urea and / or monopotassium phosphate and chelating-state trace elements into the solution obtained in the step (1) in a stirring state, and stirring for 20-50 minutes to obtain the liquid algae amino acid microbial fertilizer. According to the invention, algae is subjected to deep fermentation by use of a high-activity microbial agent, the natural active ingredients in algae are perfectly maintained; and due to compatibility with the chelating-state trace elements, the nutrient elements and utilization rate of the fertilizer are improved, and the algae amino acid microbial fertilizer is a novel algae microbial fertilizer for bioremediation and soil adjustment and conforming to ecological balance of animals, plants and microorganisms.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a preparation method of seaweed amino acid microbial fertilizer. Background technique [0002] In recent years, with the development of the economy, people have paid more and more attention to the living environment and quality of life, and food safety issues have attracted more and more attention from all aspects of society. These changes have challenged the original agricultural production model, and finding new agricultural measures that meet the needs of sustainable agricultural development has become a hot spot in current agricultural production research. [0003] For a long time, fertilization technology has been one of the important means to ensure the smooth progress of agricultural production. However, the long-term use of a large amount of inorganic fertilizers and unreasonable fertilization measures will cause fertilizer pollution in agricultural produc...
