摘要
PROBLEM TO BE SOLVED: To provide a nutritious liquid supply method to a plant cultivation bed and a nutritious liquid supply system to the plant cultivation bed which can prevent grow inhibition due to high salt concentration and promote plant growth.SOLUTION: In a nutritious liquid supply method to a plant cultivation bed, digestive juice generated by methane fermentation of biomass is carried out desalinization to reduce salt concentration of the digestive juice, and the digestive juice after desalinization is supplied as nutritious liquid to a plant cultivation bed in which plant is cultivated. A nutritious liquid supply system to the plant cultivation bed comprises: a methane fermentation tank for generating the digestive juice by methane fermentation of the biomass; a demineralizer for reducing salt concentration of the digestive juice generated in the methane fermentation tank; and the plant cultivation bed for cultivating plant by being supplied the digestive juice having reduced salt concentration by the demineralizer as the nutritious liquid.
