Objective: To research the effects of different concentrations of trace elements zinc on yield and effective components of Rabdosia rubescens under field condition

and to provide scientific basis for proper application of trace elements zinc. Method: Foliar application of different concentrations of trace elements zinc In the initial stage of growth and development of R. rubescens，according to the yield and content of the results of analysis of oridonin

rosmarinie aci and ponicidin，filtering out the best spraying concentration. Result： Compared with spraying water

0.10% of the zinc could make the R. rubescens high yields and improve its effective components，increase yields 16.5%

enhance the content of oridonin 40.28%. Conclusion ：Rational application of zinc could increase the yields and made an obvious improvement in the content of oridonin.
