The invention relates to a low light tolerant culture method for a vegetable. The low light tolerant culture method for a vegetable comprises the following step: under a culture condition of insufficient illumination intensity, spraying a fertilizer to leaves of a plant at the early stage of each growing period of the vegetable, wherein the fertilizer contains organic carbon and a silicon compound; the mass percent of the organic carbon in the fertilizer is 15-25%; the mass percent of the silicon compound is 0.1-0.5%; and the organic carbon is at least one of amino acid, saccharide and alcohol. The low light tolerant culture method for a vegetable is simple to operate, and can increase the yield of the vegetable.
