It takes special technologies to apply arbuscular mycorrhiza fungi to the land reclamation. This paper studies sunflower growth, soil properties remediation and microbe population fluctuation after arbuscular mycorrhizal fungi being inoculated on the Shendong coal mine subsided land for 5 months. The following results are obtained. Arbuscular mycorrhizal fungi can shift the plant flowering period two weeks earlier than the control group. After 5 months growth, the mycorrhizal inoculation rate and the hyphal density are both increased. Mycorrhiza can promote plant growth. The leaf number and the weight of the mycorrhizal plants are increased as compared with the control group. The mycorrhizal plant root extends well. Mycorrhizal plant's dry weight is higher than the control group. The sunflowers' productions are also increased. The effectiveness of phosphorus and potassium is increased in the mycorrhizosphere soil. The populations of the microorganism are increased. All those show that their ecological effects are significantly improved. Arbuscular mycorrhizae would promote reclamated soil properties that will help the rehabilitation and sustainability of the ecological systems. These results provide a theoretical base for the micro-reclamation application in the coal mine areas, also for the reclamation practice. |
