              RYL designed and conducted this experiment, and she also
            
            
              completed and modified the first draft. PTG was in charge of
            
            
              experimental design, data analysis, writing and modification of
            
            
              the manuscript. XYL participated in the experimental design
            
            
              and provided instructions on the application of materials. DGZ
            
            
              was the project leader.

              advices, and his reading and reviewing on this paper. We
            
            
              wouldalso like to thank technicians, ZGL, from HITAR for
            
            
              planting and caring for the populations. Lastly, we want to
            
            
              thank the two anonymous reviewers for their useful critical
            
            
              comments and advices on this paper.
