Factory-like soilless culture method for gastrodia elata

The invention discloses a factory-like soilless culture method for gastrodia elata. The factory-like soilless culture method for the gastrodia elata is characterized in that intelligent factory facility construction is standardized, the factory construction goal can achieve annual production and cultivation of the gastrodia elata in 365 days, intelligent temperature control, humidity control, light control and oxygen control are achieved, and a steam high-temperature sterilization and disinfection device is installed; after a factory is built, the ground needs to be hardened, drainage ditches are reserved, galvanized square pipes are adopted in the drainage ditches to form shelves with the length, the width and the height being 12 m * 1.5 m * 5 m, aisles with the width being 1 m are reserved in the middles, 15 layers of the shelves with the height being 5 m are arranged, and the layer height is 32 cm. According to the factory-like soilless culture method for the gastrodia elata, a compound substrate is mainly
