Culture material for cultivating pleurotus citrinipileatus sing by using waste pleurotus eryngii and culture process of pleurotus citrinipileatus sing

The invention discloses a culture material for cultivating pleurotus citrinipileatus sing by using waste pleurotus eryngii. The culture material is prepared by mixing the following materials in percentage by mass: 30-65% of waste pleurotus eryngii, 5-15% of corncobs, 5-25% of saw dust, 5-20% of bran, 5-15% of corn flour and 2% of light calcium carbonate. When the culture material is used for cultivating the pleurotus citrinipileatus sing, not only is the utilization problem of the waste pleurotus eryngii solved, but also the raw material cost is greatly reduced, and the economic benefit brought to a producer is also increased; and the pleurotus citrinipileatus sing cultivated by using the culture material is yellow or bright yellow in body, beautiful in shape and white in pulp, and three crops of pleurotus citrinipileatus sing can be harvested.
