Effect of AM fungus on camphor seedling growth and soil nutrients

Abstract

Abstract: Three treatments of non-inoculated control（CK）, inoculation with Glomus mosseae （G.m） and inoculation with Glomus intraradices （G.i） were used for potting test. The dry matter quality of roots, stems and leaves of seedlings and the contents of potassium and phosphorus in soil of seedlings were measured three months later. The results showed that after three months, the infestation rates of CK, G.m and G.i were 0, 32.38% and 29.97%, respectively, which increased the biomass of G.m and G.i seedlings by 52.9% and 32.8% compared with that of CK. G.m treatment increased 27.4% effective phosphorus content and 38.3% effective potassium content, and G.i treatment increased 20.8% effective phosphorus content and 23.1% effective potassium content, respectively. Both species of AM fungi could successfully infect seedlings of camphor, increase the content of effective potassium and effective phosphorus in the soil and promote plant growth, and Moses Ballooney was more effective in promoting the growth of seedlings and activating soil potassium and phosphorus.

Key words: arbuscular mycorrhizal fungi, camphor, soil nutrients, biomass
