Field Experiment of Ecological Restoration Application of Arbuscular Mycorrhizal Fungi Inoculation on Amorpha Fruticosa
摘要
Abstract
[Objective] The ecological restoration effect of inoculation of Amorpha fruticosa in mining area of degraded vegetation was studied,to provide theoretical basis and field experimental data for the application of arbuscular mycorrhizal fungi in the ecological reconstruction of arid and semi-arid coal mines in Western China.[Methods] Take Amorpha fruticosa as the host plant,the symbiotic status of arbuscular mycorrhizal fungi and Amorpha fruticosa was observed in fieM conditions and the improvement of plant rhizosphere soil in coal mining subsidence area was studied.[Results] Through 4 years continual monitoring,the results showed that the inoculation promoted the growth of Amorpha fruticosa,inoculation survival rate was higher than 30％;the mycorrhizal infection rate and hyphal density of inoculated Amnorpha fruticosa were significantly higher than those of the control;the rhizosphere soil available phosphorus of the inoculated Amorpha fruticosa increased and the pH value decreased.According to these,the ecological restoration effect was achieved.[Conclusion] Under field conditions,mycorrhizal fungi can promote the formation of plant-mycorrhizal symbiosis and improve the nutrient environment of plant-mycorrhizal symbiosis.关键词
