The dynamic change of absorption ratios of molybdenum,boron and selenium by red soil with culture time under indoor condition were studied. The results showed that the absorption ratio of molybdenum didn’t increase with the increasing concentration(0,0.5,1.0,2.0,4.0 mg·kg-1)of applied molybdenum. And the absorption ratio of molybdenum by red soil of applying 1 mg Mo·kg-1 soil reached the maximum. After applying different concentration of molybdenum, the absorption ratio of molybdenum decreased first and increased later with culture time. The absorption ratio of boron by red soil decrease gradually by the increasing concentration(0,1.0,3.0,5.0,7.0 mg·kg-1)of applied boron. And the absorption ratio of boron by red soil of applying 1 mg B·kg-1 soil reached the maximum. After applying different levels of boron, the absorption ratio of boron increased first and decreased later with culture time. After applying different concentration(0,0.5,1.0,1.5,2.0 mg·kg-1)of selenium, the available selenium content in red soil decreased first and increased later with culture time. The absorption ratio of selenium by red soil was keeping in a high level through the whole experiment period.
