封育法恢复胡杨林,虽然时间较长,但却是经济有效的方法。1960年以来,额济纳旗林场先后封育了河流两岸居民点附近及沙漠戈壁边缘的胡杨、柽柳天然次生林共15,412亩。通过16年来的观察,我们认为封残育林是恢复胡杨天然次生林的好办法。胡杨是干旱荒漠地区遗留下来的宝贵阔叶树种,它有较强的限蘖萌芽能力,凡在地下水为1—8米的范围内,均能自然生长根蘖苗,每丛4—40株,一般生长在树冠之外。大树被采伐后,距树根1—5米有少量萌生根蘖
Sealing method to restore Hu Yang Lin, although a long time, but it is a cost-effective method. Since 1960, Ejin Banner forestry farm has successively closed up a total of 15,412 mu of natural secondary forests of Populus euphratica and Tamarisk near the settlements on the banks of the river and on the edge of the desert. Through 16 years of observation, we believe that sealing residual forest is a good way to restore natural secondary forests of Populus euphratica. Populus euphratica is a valuable leaved species left in the arid desert region, it has a strong capacity of limited tillering, where the groundwater is within the range of 1-8 meters, can grow naturally tillering seedlings, 4-40 plants per cluster, the general Grow outside the canopy. After the tree was harvested, root 1-5 meters away from the root of a small amount of root tillers
