摘　　要：采取分次刈割的方法,对煤矿区废弃物中接种丛枝菌根真菌对紫花苜蓿的生长状况、营养吸收进行动态监测。结果表明,在煤矿区废弃物中,接种摩西球囊霉菌根真菌苜蓿的侵染率大于接种地球囊霉菌根真菌的侵染率。丛枝菌根真菌对宿主矿质营养吸收尤其是磷吸收有一定促进作用,接种菌根使植物从基质中吸收氮、磷的强度比对照高,在第6个月时磷含量达到高峰,而对照在第9个月时才达到高峰。With the methods of periodical cradle, the growth and mineral nutrition adsorption of alfalfa will be monitored in the solid wastes from coal mine. The results show that the infection rate of G. mosseae is heigher than that of G. geosporurn. AM fungus can increase the host adsorption of mineral nutrition especially phosphorus. The P and N adsorption intensity of mineral nutrition in mycorrhizal plants is higher than that of no mycorrhizal plants. The P content of the former reaches the maximum value at the sixth month, but the one of the latter reaches the maxmum volue at the ninth month.
