Novel soilless cultivation device

A novel soilless cultivation device comprises a cultivation floating disc, wherein a plurality of planting holes are uniformly distributed on the cultivation floating disc, and bottom holes are formed at the bottoms of the planting holes; the cultivation floating disc is placed in a container filled with liquid, a drain hole is formed on the wall of the container; a plurality of hair-shaped matrix bodies are arranged in the planting holes, and a plurality of grooves are vertically formed on the hair-shaped matrix bodies; and the hair-shaped matrix bodies are made of hydrophilic materials, such as polyester fibre, glass fibre, plastics, or rubbers. By adopting the novel soilless cultivation device provided by the utility model, concrete, plastic films and the like are not required to be used, thereby saving resources and protecting environment; the effects of water absorption and water retaining capacity of the matrix are ensured, furthermore, the links of manufacture, transportation and sale of a traditional
