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
