摘　　要：研究了不施肥与施P肥3种丛枝菌根菌Gigaspora rosea(Gi.r)、Glomus mosseae(G.m)和Glomus versiforme(G.v)对棉花生长及产量的影响。结果表明,丛枝菌根菌可显著提高棉花叶片光合速率,改善水分状况,促进棉花生长发育,提高籽棉产量,尤其是霜前花产量。其中以接种G.v处理对棉花增产效应最大。Effects of arbuscular mycorrhiza fungi (AMF) including gigaspora rosea, glomus mosseae and glomus versiforme on growth and yield of cotton in fertilized and non-fertilized fields with phosphorus(3Ca(H2PO4)2·H2O + 7CaSO4) are studied. The results show that the AMF is able to increase the photosynthetic rate, improve water status,promote cotton growth and increase its yield ,especially the yield before frost season. Glomus versiforme is the most ef-fective species in increasing cotton yield.
