Abstract: In order to guide the rational fertilization about Anemarrhenae rhizoma, and provide the technical support for its standardized cultivation and application of different kinds of basal species and different fertilizer amount when Anemarrhenae rhizoma were transplanted, this paper studied the influence of basal fertilizer on growth characteristics and active ingredient content of Anemarrhenae rhizoma. The results showed that under different fertilizer treatments the plant height, matter accumulation and active ingredient content all  increased, but no significant difference between each other. The influence of different fertilizing amount of Anemarrhenae rhizoma on the dry and fresh weight of rhizoma and fibres, total plant dry matter accumulation and the influence of the active ingredient content were presented B3>B2>B1. Due to no significant difference between B2 and B3, considering the cost problem, B2 fertilizing amount was choose. Among different fertilizer types,  Anemarrhenae rhizoma growth characteristic index and the influence of active ingredient content were not significant. A2B3 was the best from the datas of matter accumulation, but the effect of organic fertilizer was better than the inorganic fertilizer from the content of active ingredients. Considering the influence of basal fertilizer on Anemarrhenae rhizoma growth characteristics and  the content of active ingredients, A1B2 worked best. The results provided the fertilizer practice for the standardized cultivation of Anemarrhenae rhizoma.
