NOVELTY - Fertilizer comprises 4 pts. fresh broken egg shell, 0.7 kg farmyard manure, 750 g rice washed water, 200 g wet sludge, 600 g animal offal or animal carcasses, and 1 kg plant ash. The preparation of fertilizer comprises adding the raw materials into a wide-port container, evenly mixing, fermenting, removing the fresh air from the container, adding 5 kg rice washed water, re-sealing and fermenting, removing waste, squeezing out the liquid waste, filtering the residue using fine gauze filter, re-crystallizing the filtered liquid to obtain crystals, then packing in a pouch, sealing, and storing.    USE - The fertilizer is useful for cultivating indoor flowering plant (claimed).    ADVANTAGE - The fertilizer satisfies the growth requirements of different flowering plants.    DETAILED DESCRIPTION - Fertilizer comprises 4 pts. fresh broken egg shell, 0.7 kg farmyard manure, 750 g rice washed water, 200 g wet sludge, 600 g animal offal or animal carcasses, and 1 kg plant ash. The preparation of fertilizer comprises adding the raw materials into a wide-port container, evenly mixing, sealing the port with a plastic film, placing the container under sunlight, fermenting for 10-25 days until there are no bubble generation on the surface, removing the fresh air from the container, adding 5 kg rice washed water, re-sealing and fermenting for 5-8 days, removing waste, squeezing out the liquid waste retained in the container, filtering the residue using fine gauze filter with three layers, re-crystallizing the filtered liquid to obtain 17-20 g crystals, then packing in a pouch, sealing, and storing in dark. The use method of fertilizer crystals comprises mixing 4-5 g crystals with 20-30 g charcoal residue, uniformly burying 3-5 cm deep into the soil around the plant pots, where the fertilizer layer has thickness of 3-5 cm, pouring enough boiled water over three days under sunlight, or directly watering pond water or river water, preferably rain water, and then watering once again soon after the initial water absorbance until there is no bubble generation and the underlying soil is saturated.
