NOVELTY - Use of a combination of plants, insects, animals, and microbial inoculants for a completely ecological greening, housefly larvae, and chain style method to keep chickens.    USE - The combination of plants, insects, animals, and microbial inoculants are useful for a completely ecological greening, housefly larvae, and chain style method to keep chickens (claimed).    ADVANTAGE - The cost of this ecological chain type of cycling utilization is low and development potential is huge.    DETAILED DESCRIPTION - Use of a combination of plants, insects, animals, and microbial inoculants for a completely ecological greening, housefly larvae, and chain style method to keep chickens, where (a) plants and flowers that are fit to be planted in doors are planted in basins at vacant place of in-door chicken farm; the leaves of plants can absorb a certain concentration of harmful gas in air; (b) plants and flowers planted in basin outside of rooms are transported in doors for several days and then they are replaced by other group of plants to strengthen fresh of air in doors and to assure purifying effect of air; (c) the energy-conservation plants photo electricity light pipe is installed for basin-planted plants and flowers in doors to increase light; (d) a bracket plant is hung at 10 centimeters top of each 6-8 chicken in cages so that long vines of green leaves cover cages; (e) a small plastic basin with combination of organic fertilizer and soil is put at place where the eggs are obtained; the buds of paddy taken from budding room are sprayed on surface of soil in basin and then they are pulled out to feed chicken after they grows for 7-8 days freely, which can not only purify air, but also supplement green feed for chicken; and (f) in cold winter, the wheat is for budding. The organic fertilizer soil and wheat bud are mixed and then put into basins with proper water. The water is not too much but to keep the soil wet. The best growth time for feeding chicken with seeds is 15 days.
