The invention discloses a cultivation bag material capable of increasing the yield of tremella. The cultivation bag material comprises the following components in parts by weight: 10 to 25 parts of traditional Chinese medicine dreg mixture, 30 to 60 parts of wood dust, 30 to 50 parts of corn pulp dry powder, 20 to 45 parts of wheat bran and a sufficient amount of water, wherein the traditional Chinese medicine dreg mixture comprises the following traditional Chinese medicine raw materials: mountain mint, mulberry leaves, cacumen tamaricis, mountain pine seeds, jingangtou and litchi leaves. Thetraditional Chinese medicine crushed materials are added into the cultivation bag material, so that the cultivation bag material is completely pollution-free, can provide specific nutrition for tremella cultivation and enables the variety of the cultivated tremella to be better; trace elements required by the tremella are added, so that the cultivated tremella is vigorous in hypha growth, thick and strong in mushroom body, large and thick in mushroom cover, high in yield and high in commodity trait; the cultivated tremella has the advantages that the hypha grows early and the sporocarp develops well, and the yield of the tremella is greatly increased; and the source of the raw materials is sufficient, the technology is simple and easy, the cost is low, the yield is high, the conidial powder is full, grains are not needed, and the cultivation bag material is quick in response and suitable for wide popularization and application.
