PURPOSE: A manufacturing method of environmentally-friendly functional liquid fertilizer exclusively for facility cultivation irrigation is provided to increase crop resistivity and to supplement insufficient nutrients of SCB(Slurry Composting Biofiltration) liquid by manufacturing liquid fertilizer by mixing nitrogenous guano with natural potassium sulfate in a low concentrated SCB liquid. CONSTITUTION: A manufacturing method of environmentally-friendly functional liquid fertilizer exclusively for facility cultivation irrigation comprises the following step: mixing guano-nitrogen and natural potassium sulfate in the SCB liquid. The guano-nitrogen and natural potassium sulfate are pulverized into a size of 250-350 meshes and are mixed into the SCB. The SCB liquid, guano-nitrogen and natural potassium sulfate are mixed with a mass rate of 4-6:3-5:1. The liquid fertilizer in which SCB liquid, natural potassium sulfate, and guano-nitrogen comprises 5-10 wt% of nitrogen, 3-8 wt% of phosphoric acid, 4-8 wt% of kali, 1-4 wt% of sulfur, 6-8 wt% of glycine betaine 4-6 wt% of seaweed extract ascophyllum nodosumt of residual amount of water. |
