The invention relates to an alga
microorganism fertilizer agent and a preparation method thereof and belongs to the technical field of aquiculture and the like. The alga
microorganism fertilizer agent is fermented in such a way that
monosodium glutamate waste liquid, alga paste,
photosynthetic bacteria, actinomycetes, azotobacters and
bacillus subtilis are compounded, and meanwhile,
chitosan,
chitosan oligosaccharide, microelements and molasses are added according to appropriate parts. The alga
microorganism fertilizer agent is formed in such a way that the
monosodium glutamate waste liquid is adopted for
fermentation, and the raw
materials preparation is simple; high-content compound
bacteria are contained (the content of the
bacillus subtilis is larger than three hundred million / mL, and the total content of the
photosynthetic bacteria, the actinomycetes and the azotobacters is larger than one hundred million / mL) and the fertilizing effect is obvious; and the alga microorganism fertilizer agent also has a function of purifying
water body, has a wide application range, and is suitable for sea-water and fresh-water cultivation.
