The present invention is in the seaweed sprout vegetable and cultivation method, especially by cultivating the seaweed by organic farming method in the soil of land, the salty peculiar to the seaweed is reduced to 35-50%, there is no bitter taste, easy to intake and increased usability It relates to a seaweed sprout vegetable and cultivation method characterized by providing a method for producing a sprout,In mid-October, the red maple leaves were harvested and dried in a plastic house at 5-7 wt% of moisture for 5-7 days in a plastic house, followed by hair removal, and then harvested 1-1.2 mm of seeds. Hamcho seed harvesting step of filtering; By-products of seaweed or seaweeds, seaweeds, and namul ashes are collected and placed in a concrete storage tank on the ground, and doubled by 100% by weight of seaweed by-products or salt plants and sawdust by 100% by weight of seaweed by-products or salt plants. 10 to 15% by weight, 5 to 10% by weight of oyster and conch shellfish powder are mixed and fermented for at least 6 months to filter the fermented salted plant fermented product to separate the liquid and the dry matter. The fermentation drying machine is prepared after fermenting the salted plant fermentation compost, which is chopped with a grinder and dried to make fermentation powder of 30-35 mesh; Prepare plastic bed or rice bed with 500 × 300 × 100mm standard, prepare fermented powder compost with loess, side leaf soil and salt plant as top soil, and compost ferment powder with ocher, side leaf soil and salt plant 30% by weight: 40% by weight: 30 Mixing with a proportion of weight percent to prepare a bed and top soil to make the top soil for cultivation; Soak seaweed seeds in water for 5-8 hours, soaked in the rice tray to remove moisture while remaining slightly moistened, and soak the seaweed seeds at 1.5-2cm or 2-3cm intervals so as not to be smothered after putting the seaweed cultivation soil on the bed plate. And, after sowing the seaweed cultivation t
