Plant growth and root development after inoculation of arbuscular mycorrhizal fungi in coal mine subsided areas
A field experiment was conducted to study the ecological effects of arbuscularmycorrhizal fungi (AMF)(Glomus mosseae, G.intraradices) on the growth of Prunusjaponica, L.and their root development in the degenerated mining subsidence sandy land.Mycorrhizal colonization rate, plant and root growth and soil properties such as soil moisture, soil pH and soil electric conductivity, soil available phosphorus content, soil acid phosphatase activities and soil microbe populations were determined after inoculation mycorrhiza fungi for one year.Results showed that AMF improved the shoot and root growth of Prunusjaponica L., and significantly increased root colonization.Except for the soil electric conductivity and soil acid phosphatase activity, single inoculation had better performance than the co-inoculation.Single inoculation of G.intraradices had good performance in plant height, soil moisture, and soil bacteria quantity; while single inoculation of Gmosseae had good performance in soil available phosphorus concentration and soil fungi quantity.It can provided a good way for the further ecological restoration.
