Effects of agricultural managements on the function of arbuscular mycorrhizal fungi

Arbuscular mycorrhizal fungi(AM) exist widely in agricultural system, which may be associated with the vast majority of crop to be arbuscular mycorrhiza symbiosis. AM can improve nutrient and water absorption of the crops, and increase crop yield and resistance to biotic and abiotic factors and improve soil structure. Tillage, straw mulching, crop rotation, fertilizer, pesticides and other agricultural management practices will influence the diversity of AM fungi, hyphal length and the infection status of crops which will affect the function of AM fungi in pastoral agricultural ecosystem. No tillage, straw mulching, crop rotation, organic fertilizer can promote the infection of AM fungi which have significant impacts on the diversity of AM fungi. However, tillage, monoculture, fertilizers, fungicides can reduce the infection of AM fungi which also have influence on the diversity of AM fungi. The present paper summarized and reviewed the effects of agricultural management measures on AM fungi diversity and function, aiming to improve pastoral agricultural ecosystem productivity through the application of AM fungi.
