The invention discloses an
organic fertilizer for preventing and controlling soil-borne
pathogenic bacteria of green plants and a preparation method of the
organic fertilizer. The
organic fertilizer is prepared from the following raw materials in parts by weight: 70-80 parts of kitchen waste, 30-40 parts of rice
bran, 25-35 parts of duckweed, 10-15 parts of
