A method for producing a liquid fertilizer by using a fermented stevia solution is provided to increase the sugar degree and freshness of agricultural crops, to enhance growth of agricultural crops, to inhibit harmful insets, and to reduce environmental pollution. A method for producing a liquid fertilizer by using a fermented stevia solution comprises: a step(10) of finely crushing dried stevia to obtain stevia powder; a step(2) of introducing the stevia powder into water in an amount of 2.5 times of the weight of the stevia powder at 70-75 deg.C for 20-30 minutes to sterilize pathogenic microorganisms contained in the stevia powder; a step(30) of cooling the water to 20-35 deg.C and introducing effective microorganisms including yeast, bacillus and actinomyces thereto; a step(40) of fermenting stevia by using the effective microorganisms at 20-25 deg.C for 2 days; a step(50) of extracting a fermented stevia solution in a squeezing instrument; and a step(60) of aging the extracted fermented stevia solution at 20-30 deg.C for 20 days to obtain a liquid fertilizer containing effective microorganisms including yeast, bacillus and actinomyces. |
