    Abstract
  • Based on briefly summarization of the ecological characteristics, ecological threats and the main ecology restoration obstacles in the rocky desertification region, the present paper systematically analyzes the ecological adaptation ability and potential for ecological restoration of mycorrhizal mulberry. Because of good characters in the developed roots, well drought-resistance and tolerance to barren soil, mycorrhizal mulberry is considered as a fast-growing forestry plant in karst environment. It plays an important role in increasing vegetation coverage, promoting environmental improvement and realizing fragile ecosystem restoration and balance. Especially because of the special eco-physiological function of AM fungi (for example, to increase minerals and water absorption) having good corresponding relations with the main ecological obstacles drought and leanness, mycorrhizal mulberry will be a new try to overcome the barriers of vegetation restoration in rocky desertification area. Mulberry that inoculated with arbuscular mycorrhizal fungi will be able to further stimulate the absorption and transportation of mineral nutrition and water, alleviate the poor and drought stress, speed up the soil microbial community construction and increase soil biological activity as well as promote the vegetation positive succession. Usage of mycorrhizal mulberry will provide a new approach for ecological restoration in karst rocky desertification area.
