A method for manufacturing a plant growth-promoting agent by using waste glass is provided to neutralize the acidified soil by chemical fertilizer, strengthen the stem and leaf of plants and increase disease resistance of plants by using silicic acid derived from waste glass, so that environment pollution caused by waste glass is prevented. A method for manufacturing the plant growth-promoting agent comprises the steps of: mixing 25-45 wt.% of waste glass, 25-30 wt.% of cullet including Na2SiO3, 25-30 wt.% of alkali soda compounds including Na2CO3 and NaOH, 4-8 wt.% of phosphorous compounds including H3PO4, P2O5, NaH2PO4, Na2HPO4, Na3PO4, Na5P3O10, Na4P2O7, K4P2O7 and (NaPO3)6, 0.1-2 wt.5 of boron compounds including H3BO3 and Na2B4O7, 0.1-1 wt.% of Manganese compounds including MnO2, MnCO3 and MnSO4, 0-0.5 wt.% of zinc compounds including ZnCO3 and ZnO, 0.8-3 wt.% of calcium compounds including CaCO3 and 0-0.5 wt.% of molybdenum compounds including Na2MoO4 and (NH4)6Mo24; heating the mixture in an electric furnace at 1,350-1,450 deg.C for 200-240 minutes and cooling the melting solution; and pulverizing the final product. |
