The invention discloses a liquid
organic fertilizer prepared from kitchen waste, and a production process thereof, and belongs to the technical field of fertilizers. The liquid
organic fertilizer comprises, by weight, 60-70 parts of kitchen waste, 15-20 parts of
straw, 2-3 parts of zymophyte, 1-1.5 parts of
nitrogen-fixing
bacteria, 0.5-1 part of
bacillus mucilaginosus, 0.2-0.5 part of purple
bacteria, 3-5 parts of supplementary nutrients, 10-15 parts of
potassium hydroxide solution, 4-8 parts of decomposed
coal, 5-10 parts of
urea, and 200-300 parts of deionized water.
Nutrient substances aresupplemented, zymophyte continuously consumes the
nutrient substances in the high-temperature
fermentation process, after high-temperature
fermentation is finished, the
nutrient substances in
fermentation liquor are sharply reduced,
ammonium sulfate,
magnesium sulfate,
potassium phosphate and
calcium carbonate are additionally added into the fermentation liquor to supplement elements needed by the zymophyte, the
nutrient substances are kept sufficient, and the
nutrient content of the zymophyte is increased. By adding the decomposed
coal and a
potassium hydroxide solution, the activation of the decomposed
coal is facilitated, so that
humic acid is converted into a soluble state, and the absorption of crops is facilitated.
