PURPOSE: An environment-friendly liquid fertilizer manufacturing method of irrigation and cultivation under structure is provided to supplement with insufficient nutrient of SCB liquid and increase resistivity of crops by mixing SCB(Slurry Composting Biofiltration) liquid with nitrogenous guano and palm ash to manufacture liquefied fertilizer. CONSTITUTION: An environment-friendly liquid fertilizer manufacturing method of irrigation and cultivation under structure comprises the following steps. SCP liquid is mixed with guano-nitrogen and palm ash. The mixed ratio of SCB liquid, guano-nitrogen, and palm ash is 75:20:5. This mixing ratio is suitable for primary growth of the crop. The mixed ratio of SCB liquid, guano-nitrogen, and palm ash is 80:13:7. This mixing ratio is suitable for latter growth of crops. The guano-nitrogen and palm ash are differentiated to 250-325mesh and mixed with SCB liquid. The guano-nitrogen contains large amount of nitrogen, phosphoric acid, kali, etc. The palm ash contains large amount of heap ingredient. |
