Abstract: This paper chose the Salix psammophila artificial shrubbery in the Mu Us Sandy Land as research object, stumping reserve coverage, stumping stubble height, stumping time and stumping cycle time were observed. The results showed that, to promote artificial forest rejuvenation, S. psammophila should be stumped after afforestation 4-6 a. To get the highest biomass, stumping cycle of resource utilization was 4 year. When the coverage of understory herbaceous reached 18%, stumping reserve coverage was controlled in 10%; if it had no herbaceous or the coverage less than 18%, stumping reserve coverage should be up to 20%, it was conducive to prevent and avoid soil wind erosion. When the stumping stubble height is 5 cm, branches number and biomass increased.

Key words: Mu Us Sandy Land, Salix psammophila, stumping rejuvenation
