摘　　要：松土补播红豆草对昌吉市退化草地生产力的影响研究结果显示：松土补播红豆草可以有效提高天山北坡中山带退化草地的生产力水平,松土补播第2年比封围区提高82.3%~92.5%。松土补播红豆草可以显著增加天山北坡中山带退化草地植被的覆盖度和高度,松土补播红豆草2年后,植被覆盖度较封围区增加50.0%~62.5%,植被高度较封围区增加38.9~48.0%。红豆草在天山北坡中山带退化草地的适应能力很强,松土补播2年后,红豆草已成为草地植被的主要成分之一,红豆草的定植密度达到34~76株/m2,定植率21.3%～47.5%。Effect of loosening and re-sowing of Onobrychis viciaefolia on of deteriorated grassland in Changji Prefecture was studied.The results revealed that lossening and re-sowing of Onobrychis viciaefolia could effectively improve the deteriorated grassland in the north slope of Tianshan Mountains.The rate increased by 82.3%~92.5% next year.Furthermore,after two years,vegetation cover rate increased by 50.0%~62.5%.The height of vegetation increased by 38.9%~48.0%.The Onobrychis viciaefolia was highly adaptable and it became the basis of the grassland.After two years,the density became 34~76 strains/m2,the fixed value got to 21.3%~47.5%.
