A field trial was carried out to study the influence of different kinds of spring topdressing on growth, yield and quality of Ligusticum chuanxiong. The results showed that the spring topdressing had effects of improving root length, tiller numbers and plant height to some extent. At the same time the chlorophyll content and dry weight accumulation especially the dry weight of root increased significantly. It also showed that the yield increased and quality was improved significantly. The effect of different treatment with urea58.7 kg x hm(-2)(N 27 kg x hm(-2)) was the best and the treatment with N,P,K the second.
