摘　　要：通过对沙棘林不同龄组、不同季节平茬复壮效果的研究表明:沙棘林栽植后5～7a进行平茬更新效果最佳,萌蘖株数达到3.89万株/hm2,幼树生长旺盛,在平茬时间上以春季平茬效果最佳。沙棘根部萌蘖的苗木生长格外旺盛,雨季平茬效果欠佳。Study on the effect of stumping and rejuvenating of Hippophae rhamnoides Linn.at different ages and seasons showed that the optimum time of stumping and rejuvenating was 5 to 7 years after planting. The effect of stumping in the spring was best while the tiller numbers reached 398 plants per hectare and the younglings were vigorous.Growth of seedlings sprouting from root part of hipplphae rhamnoides is better.The effect of stumping in rainy season is not good enough.
