菌根技术在赤泥堆场植被恢复中的应用前景

菌根是植物根系与土壤真菌形成的互惠共生体，对提高植物抗逆能力十分重要。赤泥是氧化铝生产中排出的高碱性尾矿，赤泥堆场对环境造成不良影响，植被恢复困难。讨论了菌根的作用及其在工矿破坏区土壤修复中的应用；论述了菌根技术在赤泥堆场植被恢复中的应用策略，认为通过广泛调查和进行菌株及适生植物筛选试验，可以将菌根技术应用于赤泥堆场的植被恢复。

Application Perspective of Mycorrhizas in the Vegetation Restoration in Red Mud Tailing Dam

As a mutual symbiosis formed between plants and soil mycorrhiza fungi, Mycorrhiza plays a key role in protecting host plants against environmental stress. Red mud is the high alkaline tailings from the production process of alumina, the tailing dam of red mud has adverse environmental impacts and its vegetation construction can be very difficult. This paper discusses the role of mycorrhiza and its application in the soil remediation in mining areas, and also the technological strategies of applying mycorrhiza in vegetation restoration of red mud tailing dam. It is concluded that applying mycorrhiza technologies to the vegetation construction of red mud tailing dam is feasible through extensive investigation and selection testing of mycorrhiza fungi and its suitable plants.
