PROBLEM TO BE SOLVED: To provide a closed-system nutrient liquid cultivation method of plants in which accumulation of growth inhibition substance exuded from roots of a plant can be suppressed, and an electrolyzer for nutrient liquid cultivation, in which temperature rise of culture solution can be suppressed, and a problem that nutrient is crystallized on an electrode side and nutrient required for growth becomes short can be prevented.SOLUTION: In a nutrient liquid cultivation method in which concentration of growth inhibition substance, which exuded from a plant to be cultivated into culture solution, in the culture solution is reduced by electrolysis which is performed by applying voltage to a pair of electrodes 8, voltage to be applied to the pair of electrodes 8 is AC voltage.SELECTED DRAWING: Figure 1 |
