摘　　要：研究了在天麻生长基质中添加高Se石煤粉对天麻中Se富集作用的影响,以及对天麻吸收Zn、Cd、Pb等元素的影响。结果表明:在添加高Se石煤粉0～20g/kg浓度范围内,天麻能有效地富集Se;并且可促进天麻对微量元素Zn的富集,还能拮抗污染元素Cd和Pb的积累。The cultural method of stone coal powder with Se- rich added into growth matrix of Gastrodia elata B was studied for the accumulation of Se in Gastrodia elata B and the influence on the content of Zn, Cd, Pb etc. The results indicated that: added with stone coal powder with Se- rich, Gastrodia elata B can efficiently accumulate Se; within the concentration range of 0～20 g/kg, stone coal powder rich in Se could make Gastrodia elata B efficiently accumulate Se, improve the accumulation of Zn and hinder the accumulation of polluting elements: Cd and Pb.
