Abstract: The objective of this study was to investigate the effect of temperature raising on solubility of trace elements in soil, and the bioavailability of trace elements in spring wheat (Triticum aestivum L.) A simulated warming manipulation was conducted to evaluate the effect of temperature raising on Cd, Cu, Fe and Zn accumulation of spring wheat in Dingxi, Gansu province, the semiarid northwest of China. The results of the study revealed that temperature raising will lead to a significant change in trace element concentration in soil and spring wheat. Compared with control, the strongest effects of 3℃ temperature raising were that the trace elements concentrations in grain of Xihan 1, Xihan 2 and Xihan 3 decreased by 43.4%, 11.1% and 13.4% on Cd, and 30.4%, 25.1% and 10.8% on Cu, respectively. But it was converse for the concentrations of Fe and Zn in grain of spring wheat, the concentration of Zn increased by 28.9% and 35.8% respectively in grain of Xihan under 1℃ and 3℃temperature raising treatments. According to the change of temperature raising with 1.9℃ by 2050 in semiarid northwestern of China, the elements concentrations in spring wheat will be in a range of Cd (0.59-0.65 mg/kg), Cu (5.91-7.64 mg/kg), Zn (63.73-69.41 mg/kg) and Fe (185.23-202.70 mg/kg), respectively.
