The invention relates to a seedling-raising medium, and especially relates to a seedling-raising medium production method. The method is characterized in comprising the following steps: a, waste furfural residue is composted and fermented, wherein urea is added before fermentation for adjusting a carbon-nitrogen ratio to 25:1; during fermentation, turning time and frequency are determined according to fermentation temperature; b, fermented and composted furfural residue is subjected to sunlight exposure; c, the fermented and composted furfural residue, perlite, vermiculite, furnace slag, urea, monoammonium phosphate, potassium sulfate, carbendazim and the like are weighed according to a certain ratio, and are well mixed, such that the seedling-raising medium is obtained. The seedling-raising medium has unique raw materials. With the seedling-raising medium, the soilless cultivation yield is high, the cost is saved, pest and disease seldom occur, the production period is short, weather and season influences are low, and vegetable products are provided with good flavors and quality. The medium and the method facilitate the realization of agricultural mechanization and automation, and facilitate standardized management.
