| Abstract: | Stumping of desert shrubs(Calligonum rubicundum,Atraphaxis bracteata and Hedysarum scoparium) in south margin of Tengger Desert has significant effect on their growth and shows little effect on rejuvenation of Caragana korshinskii.The optimum time of stumping is in the middle and last ten days of April.The optimum height of stubble is 30 cm or 40 cm for Calligonum rubicundum and Hedysarum scoparium,20 cm or 30 cm for Atraphaxis bracteate,40 cm or more for Caragana korshinskii. |
