Abstract:The UN Intergovernmental Panel on Climate Change (IPCC) pointed out that nitrogen deposition was being increasingly intensified along with climate warming. In this paper, we conducted a multi-factor experiment from 2005 using Artemisia frigida, a Mongolian traditional medicinal plant in Inner Mongolia steppe, to study the effect of simulated warming and nitrogen addition on 12 essential element contents and their allocation in reproductive branches (vegetative branches) by ICP-AES. The four treatments were: CK (ambient), IR (warming), N (nitrogen addition) and IRN (warming plus nitrogen addition). The simulated warming was 2 ℃, and the total amount of added NH4NO3 was 10 g N·m-2·a-1. In this study, our result showed that warming and nitrogen addition influenced the essential element absorption and distribution. Compared to ambient, there were different variations in 12 essential element contents at warming condition, but the negative effects were more than the positive effects. Nitrogen deposition significantly increased absorption of P and Mn, but no interactive effect of warming, Nitrogen deposition, and different part on all of 12 element contents. In addition, absorption and allocation of N, K, Ca and Mg were significantly different between reproductive branches and vegetative branches (P<0.05).
