长白山区防治朝鲜崖柏扦插苗冻拔害的试验

摘要

The effect of different chill-proof measures on frost heaving damage prevention in alpine region of Changbai mountain was researched by taking 2 a Thuja koraiensis cutting seedling as material.The result showed that setting windbreak with two-layer and six-neede sunshade net worked best and the survival rate was 100 %.The root system of cutting seedling which was made the cold-proof treatment was pulled out and dead in the end.The survival rate was 0.%以朝鲜崖柏2 a生扦插苗为试验材料,研究在长白山高寒地区不同防寒措施对其防治冻拔害的效果,结果表明:以设立风障+覆盖二层六针遮阳网效果最好,成活率为100 %;不进行防寒处理(CK)的扦插苗根系全部拔出致植株死亡,成活率为0.
