A preparation method of a calcareous silicate fertilizer containing pyroligneous liquor is provided to make best use of effective elements and high water absorption properties of the pyroligneous liquor. A preparation method of a calcareous silicate fertilizer includes the steps of: baking waste shells or egg shells at 1000-1200deg.C and pulverizing the waste shells or the egg shells; mixing 100wt% of the baked waste shell powder or egg shell powder with 80-120wt% of 60-80deg.C water to cause hydration; baking biotite at 900-950deg.C and pulverizing the biotite; and adding 100wt% of a mixture, which is composed of 60-70wt% of the waste shells or egg shells and 40-30wt% of the biotite powder, into 20-35wt% of water containing 4-8% concentration pyroligneous liquor. |
