摘　　要： 研究一套科学有效的草甸草原入侵植物少花蒺藜草的生态防控措施对于保障草原的生态生产安全具有重要意义。大面积试验证明采用机械翻耕可显著降低少花蒺藜草的出苗率,翌年出苗率可降低64.16%;连续刈割清穗3年,入侵地少花蒺藜草出苗率可降低85.21%;补播多年生牧草紫花苜蓿、沙打旺、小冠花、沙生冰草、黑麦草、羊草和披碱草对于抑制少花蒺藜草株高、分蘖数、刺苞数及颖果数等生长发育指标均有显著成效。 A set of scientific and effective ecological control measures for invasive plant Cen- chrus pauciflorus in Liaoning northwest meadow grassland have a great significance to protect the ecological safety of grassland. The results showed that the mechanical tillage could significantly reduce the emergence rate of Cenchrus pauciflorus by large area demonstration measuring, the germination rate could be reduced by 64.16% in the next year. Continuous cutting ears for 3 years, the germination rate could be reduced by 85.21%. Sowing Medicago sativa, Astragalus adsurgens, Coronilla varia, Agropyron desertorum, Lolium perenne, Leymus chinensis and Elymus dahuricus had inhibitted the height, tillers, number of thorn bud and caryopsis of Cenchrus pauciflorus significantly.
