    Functions of arbuscular mycorrhizal fungi (AMF) in intensified farming systems have been attracting more and more attention.In the past decade,a big headway has been made in recognition of the significance of shifting from simulation in the greenhouse and laboratory to in-situ field study in the research on interactions of AMF and plants. Analysis of findings of related theoretical and applied/basic researches has led to such a conclusion that mycorrhizal biotechnology should include not only technologies for production and application of common AMF inoculums,but also techniques for regulating amount and infectivity of indigenous AMF propagules.Agricultural practices,such as rotation,intercropping,reduced or non-tillage,and application of rhizosphere signaling substances could effectively bring indigenous AMF into play.To better understand how spatial and temporal variation of indigenous AMF communities is related to their ecological functions will probably be the hot spot for future studies in this aspect.Besides,to screen and cultivate high-yielding crop cultivars or varieties that are highly responsive to AMF in fertile soils is thought to be an effective approach to enhance the use efficiency of soil nutrient resources.
