The results show that the contents of rare-earth elements, P, K and trace elements in the sclerotia of Pleurotus tuber regium are different when treating with various N sources. Except Er and Tm, the contents of rare-earth elements of La, Ho, Dy, Tb and Yb are the highest by treating with ammonium sulfate. When concerning the contents of P, K and trace elements in the sclerotia in different N source treatments, the contents of Cu and Fe are the highest by using cow dung as N source, In and P are the highest by using ammonium sulfate, K, Cl and S are the highest when using urea as N source. The correlation analysis show that certain correlation exists among the contents of rare-earth elements, P, K and trace elements in the sclerotia of Pleurotus tuber regium. Furthermore, the correlation is different by using different N sources, among which the content of Dy is positively related with the contents of P and In, Yb is highly positively related with P content and La is negatively related with S content.展开更多

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.展开更多
