The effects of different acidities and basicities on contents of rare earth, P, K and trace elements in Pleurotus tuber regium′s sclerotium and their relativities were studied by cultivating Pleurotus tuber regium in the same cultivated medium with different pH values in the paper. The results show that the contents of rare earth, P, K and trace elements in Pleurotus tuber regium′s sclerotium are different with pH values. The content of erbium in the sclerotium is the highest when pH value of the cultivated medium is 7.5; that of thulium, copper and molybdenum are the highest when pH value is 8.5; that of phosphor is the highest when pH value is 7.0; that of kalium and sulfur are the highest when pH value is 6.5; and that of indium is the highest when pH value is 8.0. It is seen that pH values are highly correlated with the contents of copper, molybdenum, sulfur and phosphor, and are medially correlated with the contents of ferrum, thulium and kalium, and are weakly correlated with the contents of erbium and indium. In addition, there are different correlative relations among the contents of rare earth, P, K and trace elements in Pleurotus tuber regium′s sclerotium; thereinto the relativity between kalium content and ferrum content is most notable.
