中文摘要	Both arbuscular mycorrhizal fungi (AMF) and earthworms often coexist in agriculture ecosystems, but very little is known on the interactions between them. A two-compartment air gap-incorporating device was used to investigate the effects of three species of earthworm (epigeic Eisenia foetida, endogeic Aporrectodea trapezoide, and anecic Pheretima guillelmi) on AMF (Glomus intraradices) under the exclusion of plant roots, and then on maize (Zea mays L.) performance and nutrients uptake. Results showed a strong correlation between hyphal length density and subsequent plant growth and nutrient uptake. Earthworms improved soil nutrients availability in hyphal compartment (HC): E. foetida improved the concentration of soil inorganic N, A. trapezoide changed the concentration of available phosphate in the soil, and P. guillelmi changed the soil's physical properties. We found some indications that different species of earthworm and AMF might interact within the soil. Earthworms and AMF mainly acting on different nutrients create distinct niches for plants. The feeding and burrowing activities did not significantly destroy hyphal length density and made negative affect on plant performance.
