The invention relates to a soilless culture method for white pea sprout vegetables, and belongs to the field of agricultural technologies. The soilless culture method mainly includes steps of firstly, mounting culture frames, seedling growing trays and tungsten filament lamps and preparing sprinklers; secondly, accelerating germination of seed grains, to be more specific, soaking seeds in clear water at the temperature of 27-28 DEG C for 20-24 hours, fishing the seeds out of the clear water, keeping the temperature at 28-30 DEG C and accelerating germination; thirdly, transplanting seed buds, to be more specific, carefully scattering the seed buds on stainless steel meshes of the seedling growing trays, carefully stroking and spreading the seed buds, preferably occupying each mesh with a single seed bud and placing the trays on shelves of the culture frames after the seed buds are spread; fourthly, carrying out cultivation management, to be more specific, spraying clear water once at the intervals of 6-8 hours, spraying fertilizer liquid once every 20-24 hours, stopping spraying the fertilizer liquid 3 days before the white pea sprout vegetables are harvested, keeping illumination for 15-18 hours on a daily basis and keeping the indoor temperatures at 25-30 DEG C; fifthly, harvesting the white pea sprout vegetables and selling the white pea sprout vegetables on markets 5-6 days after the seed buds are transplanted. The fertilizer liquid comprises 0.5% of urea, 0.3% of potassium chloride and 0.2% of monocalcium phosphate. The soilless culture method has the advantage that the vegetables can be supplied by the aid of the soilless culture method.
