Effects of arbuscular mycorrhizal fungi on ecological restoration in coal mining areas

Effects of arbuscular mycorrhizal fungi on ecological restoration in coal mining areas In the coal mining subsidence areas in arid and barren locations in western China where plants are difficult to grow, the root of A. fruticosa was inoculated with arbuscular mycorrhizal fungi (AMF). The effects of inoculation with AMF on the growth of A. fruticosa and improvement of the degraded soil were determined. Results showed that the selected AMF and A. fruticosa had a strong symbiotic relation. Sixteen months after inoculation, the root colonization rate in A. fruticosa reached 88%. Inoculation with AMF was shown to promote the growth and root development of A. fruticosa and improve rhizospheric soil and fertilization of A. fruticosa. After the inoculation, the contents of organic matters and glomalin-associated proteins in the rhizospheric soil of A. fruticosa increased significantly. Sixteen months after the inoculation, the acidic phosphatase activity in the rhizosphere of A. fruticosa in the inoculated plots increased by 44% compared with that of the control plot, and the content of available phosphorus was 2.5 times that of the control. Hence, inoculation with AMF improves the rhizosphere of A. fruticosa, promotes a stable ecosystem in the mining area. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals
