摘要
通过对榆林沙区飞播的沙柳(Salix psammophila)等4种灌木林进行平茬更新复壮试验,结果表明:灌木林平茬既更新了老化的树种,又增加了植被覆盖度,同时延长了灌木的生长寿命,提高了防风固沙效益;平茬可以显著提高灌木林的生长,改变衰老长势,春季平茬效果要好于冬季。
The rejuvenation experiments were conducted on four species of shrubs, such as Salix psammophila , which were planted in the Yulin Desert Area. Result shows that the shrub not only regenerate the aging tree species, but also increase the vegetation coverage and prolong the growth life of the shrub. It has improved the benefits of wind and sand fixation;stumping can significantly increase the growth of shrubs and change the growth of aging, and the effect of stumping in spring is optimal than that in winter.
