Abstract: 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.geosporum. 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.
