辽宁省西部干旱低山丘陵区,建国以来,人工造林有相当数量造林成活率不高,保存率低,影响经济效益、生态效益和社会效益的充分发挥。除气候条件不利和人为因素外,造林前不进行整地,造林时不精心栽植,不适地适树,不重视苗木质量等,也是造成失败的一个极其重要的原因。为了提高“三北”防护林工程体系建设质量,省“三北”办公室和建平县林业局、山建委、“2772”工程建设指挥部共同结合生产,进行了《提高荒山造林成活率》的开发性试验,工作从1984年开始至1987年春,通
Since the founding of the People’s Republic of China in the arid hilly region of western Liaoning Province, a considerable amount of afforestation has low survival rate, low preservation rate, and has brought economic, ecological and social benefits into full play. In addition to unfavorable climatic conditions and man-made factors, afforestation is not carried out before afforestation. When afforestation is not carried out carefully, unsuitable land for trees and poor quality of nursery stock are also an extremely important reason for the failure. In order to improve the construction quality of the “Three Norths” shelterbelt project, the “Three Norths” office and the Jianping County Forestry Bureau, Shanjiangye Committee and “2772” Construction Headquarters jointly developed the project of “Improving the Survival Rate of Afforestation on Barren Hills” Sexual testing, work from 1984 to spring 1987, pass
