Abstract: Objective To discuss the variation and the stability of the different sowing methods in area of the Achnatherum inebrians and lay the foundation for the effective prevention and control methods.MethodIn 2013, reseeding experiments were conducted on Ashili Township mountain meadow of Changji Prefecture, Xinjiang and 3 year later after sowing, A.inebrians and the edible forage went through field monitoring and research.ResultThe results showed that with the increase of replenishment time, the height of the most A.inebrians decreased, coverage and aboveground biomass increased in 2015 and then decreased in 2016, density showed a certain degree of volatility;The height and coverage of edible pasture were negatively correlated with the change of A.inebrians, density also fluctuated, but aboveground biomass showed a continuous upward trend.Comprehensive evaluation showed that B2 (unicast alfalfa (Medicago sativa)), treatment had a relatively strong inhibitory effect on the population characteristics of A.inebrians, which at the same time promoted the role of each index of edible forage.ConclusionTherefore, it is suggested that Medicago sativa should be planted in the area where A.inebrians occur, so as to achieve the goal of ecological restoration and long-term control of A.inebrians.
