PURPOSE: A cultivation method of leafy vegetables using deep sea water and an LED is provided to supply light using the LED from the germination of the leafy vegetables. CONSTITUTION: A cultivation method of leafy vegetables comprises the following steps: soaking vegetable seeds in water at room temperature; germinating the water soaked seeds in the shade at 22-23 deg C; planting the obtained seedlings in an urethane sponge when the size of dorsal roots from the seeds are 2-3mm; transferring the seedlings to a seedling raising bed, and irradiating the seedlings with light from an LED for 24 hours; circulating a nutrition solution containing deep sea water using a circulating motor around the seedling raising bed and a nutrient solution tank; supplying oxygen into the nutrient solution tank using an oxygen generator; and transplanting the seedlings to an official cultivation bed when the size of the seedlings is 6-7cm. |
