The invention discloses an
amino acid fermentation liquor preparation method, which comprises the following steps: mixing egg waste liquid with water to obtain mixed liquid; and adding white
sugar,
lactic acid bacteria and
neutral protease into the mixed liquid to carry out
fermentation to obtain
amino acid fermentation liquor after the fermentation is completed. After the egg waste liquid is fermented,
protein in the mixed liquid can be effectively converted into
amino acid, amino acid can accelerate seed
germination, and the
germination rate and the emergence rate are increased. The
amino acid fermentation liquor can also improve the
chlorophyll content of crops and accelerate the growth of over-ground parts of the crops. After amino acid enters a
plant body, amino acid has a stimulationeffect on the
plant, and the stimulation effect is mainly reflected in increase of
respiration intensity, increase of
photosynthesis and enhancement of activities of various enzymes, so that the
chlorophyll content is increased, the tillering capacity of leaves is enhanced, and better growth of crops is facilitated. The egg waste liquid is used as a
fertilizer after being fermented, so that the environmental
pollution is reduced, the additional value of an industrial chain is improved, and sustainable healthy development and virtuous cycle of the industry are realized.
