The invention relates to the technical field of vegetable planting, in particular to a culture medium for soilless culture, which comprises the following components in parts by weight: 10-20 parts ofriver sand, 20-30 parts of plant ash, 1-5 parts of gabbro, 10-20 parts of Wali wormcast, 8-12 parts of mushroom residues, 1-2 parts of brewer's grain and 1-2 parts of bark powder. The pH value of theculture medium is 6.5-6.8, and the volume weight of the culture medium is less than 0.7g / cm<3>; According to the culture medium for soilless culture of vegetables, the Wali wormcast is added and has rich humic acid and a large number of beneficial microbial bacteria, 18 amino acids and various trace elements, and nutrients needed by plant growth can be provided. Beneficial active bacteria are contained, so that the fertilizer efficiency is slowly released and the fertilizer is continuously supplied. Wormcast is an organic matrix, the cation replacement capacity is high, and the buffering capacity, namely the acid-base property change alleviating capacity, of wormcast is high.
