The Pleurotus eryngii strain as the test material was collected and isolated from the Baiyun District,Guiyang City.After ITS identification,a phylogenetic tree was established.The optimal cul-tivation conditions for Pleurotus eryngii were studied using basic biological research methods.The re-sults showed that Pleurotus eryngii belongs to the genus Pleurotus and is closely related to the facto-ry-cultivated Pleurotus eryngii.The optimal carbon source for Pleurotus eryngii was dextrin.The optimal nitrogen source was soybean meal powder.The optimal temperature range for growth was 20-25 ℃.And the optimal pH range for growth was pH 6 to pH 9.This study provided a theoretical basis for the future development and utilization of Pleurotus eryngii resources and layed a foundation for its large-scale production.
