The invention discloses a method for preparing a culture medium with Chinese herbal
medicine dregs. The method comprises the steps as follows: after the Chinese herbal
medicine dregs are accumulated for anaerobic
fermentation, compound
bacteria of
bacillus subtilis and
aspergillus niger as per the bacterial content are added and mixed uniformly to enable the bacterial content concentration to be higher than 500 thousands
bacteria per
gram, then syrup is sprayed and mixed uniformly, after accumulation, the accumulated materials are covered with a black
plastic film until the highest temperature in the accumulated materials reaches 55 DEG C, the black
plastic film is removed for aerobic
fermentation until the
moisture content of the accumulated materials is lower than 45%, and the culture medium can be obtained through accumulation and
ageing. The culture medium prepared with the method is low in
salinity, low in EC value, large in
cation exchange capacity and high in acid-base buffering capacity and
saline-alkaline buffering capacity; meanwhile, by the aid of the culture medium, the soil looseness degree, the
fertilizer keeping and
water holding capacity and the heat insulation and ventilation capacity can also be improved; the culture medium is suitable for most of crops, even flowers, plants and the like with very strict cultivation requirements, the culture medium is suitable for mixing with any materials to be prepared into required media without limitations, and salinization conditions caused by excessive use can be avoided.
