摘要
辽西气候干旱少雨,土壤含水率低,造林不易成活,苗木通过截干或平茬处理后,可减少地上部枝叶水分蒸发,并能快速恢复根系吸收功能,从而能大大提高造林成活率,并能促进苗木的正常生长发育,是干旱地区造林中一项重要举措。
It is little-rain and drought in west part of Liaoning Prov.. The soil moisture is very low,and the seedlings is uneasy to survive. Moisture evaporation of shoots above ground can be reduced after truncation or stumping of seedlings. It can increase the survival ratio of afforestation significantly and accelerate the growth of seedlings. It is one of important measures of afforestation in arid areas.
