Bidentis were studied by adopting indoor bioassay. The results showed that the volatile matter of F. bidentis had not allelopathy to four receptor plants. The eluviated matter inhibited seedling growth of cotton obviously, the inhibition ratio of root and stem were 6.29% and 10.42% respectively. The aqueous extract of litterfall and root exudates had different inhibition to four receptor plants, The synthesis effectof all treatments was significantly greater than eluviated matter treatment except for B3 of the aqueous extract of root exudates, such as the synthesis effect of all treatments (A1, A2, A3, B1, B2, B3 and eluviation) were 44.74, 29.37, 14.5, 31.54, 16.52, 3.55, 1.48 respectively.
