Abstract: By adopting mesocosm experiment, Camellia sinensis (L.) O. Kuntze var. Wuniuzao tea plant was used as test material. This paper studied the effects of inoculating arbuscular mycorrhizal fungi (AMF) on the growth of tea plant, the absorption of mineral nutrition, the water content in leaf tissue and the quality of tea under salt stress. AMF-inoculation could effectively promote growth and nutrient uptake of tea plant, deccrese the water saturation deficit and improve the growth quality of tea plant and the quality of tea, compared with ordinary cultivation. Under salt stress, the growth of treated tea plant was inhibited, and N, P, K, Mg, Fe and Zn contents in the treated tea plant, K+/Na+ ratio and fruit yield were all decreased, while inoculation with AMF could mitigate the inhibitory effect of salt stress on tea plant growth, made the N, P, K, Mg, Fe, Zn contents in the tea plants were increased by 7.7%, 31.2%, 20.2%, 23.8%, 9.4% and 9.5%, respectively, comared with the control tea plant, and made K+/Na+ ratio of the plant increased obviously. It was suggested that AMF could promote the plant growth and nutrient uptake of tea plant under salt stress, increase the plant salt-tolerance, and improve the tea yield and nutrient quality.

Key words: arbuscular mycorrhizal fungi (AMF), tea plant, salt stress, mineral nutrition, quality
