一、机械化林场更新造林除根的必要性树根是采伐跡地进行全面整地的最大障碍,拔除它用工多,劳动强度大,所以,多少年来人们只能让它埋在土中任其腐烂。目前随着更新造林面积的不断增加和造林作业机械化程度的不断提高,树根与大面积机械化造林的矛盾越来越突出,尤其在大面积机械化作业的平原林区,不拔除树根即行更新,将会造成以下不利影响: I. The Necessity of Mechanizing Forest Farms to Afforestation and Remove Roots The root of the tree is the biggest obstacle to comprehensive land preparation on deforestation sites. It requires more workers to remove it and has more labor. Therefore, for years now, people can only bury it in the soil and let it rot. At present, with the increasing of afforestation areas and the increasing mechanization of afforestation operations, conflicts between tree roots and large-scale mechanized afforestation are becoming more and more prominent. Especially in large-scale mechanized woodland areas, This will have the following adverse effects:
