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.[Method]In 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.[Result]The 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.[Conclusion]Therefore, 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.

摘要： [目的]研究补播不同牧草对醉马草(Achnatherum inebrians)发生区的规律及其稳定性,为筛选出有效的防控方法奠定基础.[方法]2013年在新疆昌吉市阿什里乡山地草甸进行补播试验,在补播后3年对醉马草和可食牧草进行实地监测.[结果]随着补播年限的增加,多数处理的醉马草高度呈下降趋势,盖度和地上生物量为2015年升高,2016年下降;密度具有一定的波动,无明显规律性;可食牧草的高度、盖度均与醉马草的变化呈负相关,密度也具有波动性,但地上生物量表现为持续上升趋势.B2(单播紫花苜蓿(Medicago sativa))处理对醉马草种群特征的抑制效果相对较强,同时对可食牧草的各指标有促进作用.[结论]在醉马草发生区单播紫花苜蓿,从而达到生态修复、长久控制醉马草的目标.
