二白杨蛀害木伐桩萌蘖恢复防护林带技术试验

The Test of Restoration Measures for Shelterbelt with Stump Sprouting on Worm-eaten Stake of Populous gansuensis

利用采伐虫害木遗留的伐桩萌蘖培育速生林结果表明:伐桩萌蘖苗比新植林带成品苗树高增加155.8%,胸径增加146.3%,节约成本93.33元/hm^2,为虫害木采伐更新恢复防护林带提供理论依据。

The results of cutting stump damaged by pests and sprouting in the fast-growing forest showed that: the seedling height of sprouting seedlings increased by 155.8% compared with that of new seedlings,increased by 146.3%, a diameter at breast height increased by 146.3%, cost saving 93.33 RMB/hm^2. It provides a theoretical basis for the restoration of protection forest belt by cutting and renewal of pest wood.
