NOVELTY - A fertilizer for cultivating indoor flowering plant comprises following raw materials: 2 wt.% fresh egg shell, 0.5 kg farmyard manure, 750 g Taomishui, 200 g waste milk, 500 g animal carcasses or animal corpse, and 1 kg of plant ash.    USE - As fertilizer for cultivating indoor flowering plant (claimed).    ADVANTAGE - The configuration of raw materials can be changed according to the characteristics and growth needs of plant. The fertilizer has wide raw material, is low cost, has simple structure, is convenient to use, is colorless and flavorless, has strong fertilizer effect, retains fertilizer effect for longer period of time, is suitable for indoor flowering plants, improves indoor environment of plant, has reduced fertilizing dosage, uses charcoal residue that reduces moisture loss of soil, reduces watering time and prolongs fertilizer effect, increases flower growth period, improves soil structure of potted flowering plant, increases efficacy of soil, and improves water absorbing time of plant. The fertilizer uses charcoal residue that allows further absorption of harmful substances in air. The fertilizer can not only satisfy the requirement of long-term growth of plant but also beautifies the indoor environment, cleans air, and plays important role in air purification of soil.    DETAILED DESCRIPTION - A fertilizer for cultivating indoor flowering plant comprises following raw materials: 2 wt.% fresh egg shell, 0.5 kg farmyard manure, 750 g Taomishui, 200 g waste milk, 500 g animal carcasses or animal corpse, and 1 kg of plant ash. The preparation process of fertilizer involves: taking the raw materials according to the weight ratio into a container, mixing uniformly, sealing the opening of the container with plastic thin film, fermenting using solar source for 10 to 25 days to form surface with no bubbles, shifting to ventilated place and then adding to the container, 5 kg of Taomishui, continuing resealing and fermenting for 5 to 8 days, taking out the dregs, squeezing out the liquid of dregs and placing the liquid into storage container to form three layered liquid, filtering water residue with fine yarn cloth filter, recrystallizing the filter liquid to form crystals of 14-19 g, placing in a pouch, packaging, sealing and storing to form the fertilizer. The method of using fertilizer involves taking 2 to 4 g of crystals formed, and mixing with 20-30 g of charcoal residue, burying evenly within soil in 3.5 cm deep plant pots, where fertilizing layer thickness is 3.5 cm, applying enough sunlight for more than 3 days or directly pouring boiling water or river water or rain water, where due to sunlight, initial water is quickly absorbed by the soil, extinguishing water again until no bubbles are formed or estimating the bottom soil, and saturating the soil.
