NOVELTY - Culturing Pleurotus eryngii using raw materials comprises (i) taking cotton seed shell, corn cob, rice husk, wheat bran, corn powder and gypsum powder; (ii) mixing raw materials to obtain mixed material, and adding water to the mixed material to obtain culture material; (iii) crushing P. eryngii strain into corn grain size, mixing with the culture material and stirring, and loading the culture material into culturing bag; (iv) conveying the culturing bag with culture material into chamber, culturing, and covering the mycelium into bags; and (v) processing fruiting management.    USE - The method is useful for culturing P. eryngii using raw materials (claimed).    ADVANTAGE - The method: does not require sterilizing process and complex procedures; produces the culture medium without any nutrient loss, and high biological conversion rate; can mix the inoculating strain and culture material to increase the inoculum size; quickly grows hypha upon germination; has less pollution rate; is suitable for industrial P. eryngii production.    DETAILED DESCRIPTION - Culturing Pleurotus eryngii using raw materials comprises (i) taking 33% cotton seed shell, 28% corn cob, 22% rice husk, 10% wheat bran, 6% corn powder, and 1% gypsum powder; (ii) mixing and uniformly stirring the raw materials to obtain a mixed material, and then adding water (specific amount) to the mixed material to maintain the water content at 55-60% to obtain culture material; (iii) crushing P. eryngii strain into corn grain size, directly mixing with the culture material and stirring uniformly, where the mass ratio of strain and culture material is 15-20:100, and then loading the culture material into a culturing bag; (iv) conveying the culturing bag with culture material into a chamber, then culturing, and covering the mycelium into the bags; and (v) processing oyster mushroom fruiting management using raw mushroom cultivation, where the fresh mushroom crop achieves 3-4 stubble ploughing, and the high biological conversion rate can reach to more than 145-200%.
