摘要: 以内蒙古毛乌素沙地沙柳(Salix psammophila)人工林为对象,对灌木林平茬预留盖度、留茬高度、平茬时间及平茬生产周期进行试验研究。结果表明:沙地沙柳造林后4~6 a内应进行首次平茬复壮,进入丰产期后平茬周期以4 a为宜,可收获最高的生物量。人工林下草本植被盖度达18%以上时,沙柳平茬的适宜预留盖度为10%;当林下草本盖度小于上述值或无草本层覆盖,平茬预留盖度应提高至20%左右,以防止引起地面风蚀。沙柳平茬适宜的留茬高度为5 cm左右,可使其萌生生长能力最强。

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
