Interactive effects of arbuscular mycorrhizae and maize ( Zea mays L.) straws on wheat ( Triticum aestivum L.) growth and organic carbon storage in a sandy loam soil

摘要

A pot experiment was conducted to study interactive effects of arbuscular mycorrhizae (AMs) and maize (Zea mays L.) straws on wheat (Triticum aestivum L.) growth and organic carbon (C) storage in a sterilized sandy loam soil. The experiment included four treatments: control, inoculation with AM fungus Glomus caledonium?(M), amendment with maize straw (S), and amendment with maize straw plus inoculation with G. caledonium (S + M). The inoculation of G. caledonium significantly (P P P G. caledonium and maize straw had no significant effects on root mycorrhizal colonization rate compared to the M treatment, while significantly (P P P G. caledonium and maize straw on soil pH (P P < 0.01), and the redundancy analysis result indicated the potential application of AM fungi in straw-returned fields.
