The invention relates to a complex microorganisms
flora grain type ascharite
fertilizer and preparation method thereof. The preparation method comprises the steps of: cultivating
bacillus subtilis and
bacillus mucilaginosus by means of amplifying bacterination, and fermenting and absorbing to obtain complex microorganisms microbial inoculum; stirring and mixing ascharite mineral
powder, manganeseore
powder,
zinc sulfate,
bentonite and the complex microorganisms microbial inoculum with a stirring device; pelleting with a pelleting device;
drying with a
drying device; and screening with a screening device to obtain the complex microorganisms
flora grain type ascharite
fertilizer. The preparation method specifically comprises the steps of: respectively weighing the raw materials according to components and weight parts in the stirring device to stir and mix for 1-2 h, pelleting with the pelleting device,
drying with the drying device, and screening with the screening device under the condition that the temperature is 10-15 DEG C and the pH value is 5-10.5. The
fertilizer can provide the
nutrition for the growth of crops; can prevent and cure physiological diseases of the crops due to the lack of
boron and
magnesium; has the functions of solidifying the
nitrogen, decomposing the
phosphorus and decomposing the
potassium, and the like, can change the host specificity of
nitrogen fixation, has no side effects to man and beast, and has no
pollution to the
soil quality as the complex microorganisms
flora has high adaptability and stable performance; and can lead the various indexes of the crops to be capable of meeting the requirement of
green food after being used, thereby increasing the quantity and improving the quality.
