NOVELTY - Use of corn straw for preparing Ganoderma lucidum producing strain, is claimed, where the application method comprises: selecting the dry, normal colored and strip-shaped maize straw as a main raw material; cutting, immersing in lime water, soaking and drying; mixing sawdust, wheat bran, corn powder and calcined lime as auxiliary materials; and mixing the raw materials with the auxiliary materials, stirring uniformly to get a mixed material, adding proper amount of water; injecting the mixture into a plastic cylinder; sterilizing; inoculating; culturing; and producing the strain.    USE - The corn straw is useful for preparing Ganoderma lucidum producing strain (claimed).    ADVANTAGE - The corn straw is rich in resources and can be used to produce the strain without requiring crushing process, thus reducing the production cost, and preventing environment pollution.    DETAILED DESCRIPTION - Use of corn straw in the preparation of Ganoderma lucidum producing strain, is claimed, where the application method comprises: selecting strip-shaped maize straw as a main raw material; cutting into the length of 25-30 cm, immersing in 2% of lime water, soaking for 20-24 hours and drying; mixing 82 wt.% of sawdust, 11 wt.% of wheat bran, 6 wt.% of corn powder and 1 wt.% of calcined lime as auxiliary materials; and mixing the raw materials with the auxiliary materials, uniformly stirring to get a mixed material, adding proper amount of the water content to the mixed material to produce a mixture; injecting the mixture into a plastic cylinder, binding an opening of the cylinder tightly to form a cultivation bag, filling corn straw until the bag is fully filled, and tying an opening of the bag tightly by a rope; sterilizing the material in the cultivating bag by a heating process; inoculating the cultivation bag material under a clean environment without pollution; culturing the bag material at room temperature of 15-30 degrees C with the relative air humidity of 60-70%; and producing the strain.
