In a greenhouse experiment, the effects of soil microorganisms and extracts <i>Achnatherum inebrians</i> on seed germination seedling growth <i>Elymus nutans</i> were studied. The results showed that both from aboveground belowground parts <i>A. significantly inhibited rate, potential, index, vigor height, root length, fresh weight <i>E. nutans</i>, but increased malondialdehyde content, catalase, peroxidase superoxide dismutase activity seedlings (<i>p</i> < 0.05). allelopathy aqueous was stronger than precipitates. Aqueous decreased by 10.45%–74.63%, 24.18%–32.50%, 19.03%–73.36%, 37.83%–88.41%, 21.42%–53.14%, 2.65%–40.21%, 20.45%–61.36%, respectively, peroxidase, 8.09%–62.24%, 27.83%–86.47%, 22.90%–93.17%, 11.15%–75.91%, respectively. above indexes higher in live sterilized soil.
