The invention relates to a strawberry culture medium, in particular to a special soilless culture medium for strawberries. According to the special soilless culture, an upper-layer medium is prepared by mixing green algae, spirogyra, zinc ash, manganese ash and silica fume, a middle-layer medium is prepared by mixing rotten wood, brewer's grains and apple pomace, and high-phosphate slag powder is taken as a bottom-layer medium. Waste is taken as a medium raw material, waste natural resources are sufficiently utilized, environmental pollution is reduced, the special soilless culture medium contains higher trace elements such as zinc, manganese and the like and meets the demands of strawberries for microorganism elements, the medium continuously and slowly releases nutritional ingredients in the planting process, accordingly, the phenomena of overnutrition at the earlier stage of strawberry planting and nutrition deficiency in the later planting period of the strawberries cannot be caused, the nutrition demand of the strawberries in the whole growth period is met, outside fertilization is not required in the culture process, all that is required is to meet the daily water demand, the medium can rapidly dredge water, microbial source germination of powdery mildew, gray mold and anthracnose is avoided, root growth of the strawberries can be promoted, a protective layer is formed on the surfaces of root systems, and the disease-resistant capability of seedlings is improved.
