To understand the function of microelements on Dodonaea viscosa growth, the effects of micro-elements (B, Fe, Mn, Zn) on the growth and chlorophyll fluorescence characteristics were studied. The results showed that all the microelements except Mn significantly promoted the growth and chlorophyll fluorescence parameters of D. viscosa (P<0.05). Biomass accumulation of D. viscosa supplemented with B was significantly higher than that of control by 133.61%. Microelement and soil types had significant interactions on leaf P concentration and N/P (P<0.05). The addition of Zn in purple soil and Fe in yellow brown soil significantly reduced the leaf N/P. The plant height, leaf area and biomass accumulation of D. viscosa in dryland red soil and yellow brown soil were higher than those in purple soil, but the root-shoot ratio and leaf N/P of D. viscosa in purple soil and yellow brown soil were significantly higher than those in dryland red soil (P<0.001). Therefore, it was indicated that microelements played an important role of in the growth of D. viscosa in dry-hot valley, and the plant growth could be promoted by adding B, Fe, Zn, especially B during the vegetation restoration process.
