陕西吴堡地处黄河沿岸土石山区,山地面积占90%以上,“山高坡又陡,熟土年年走”的自然特征成为提高枣树造林成活率的主要制约因素。经试验,采取以下集成抗旱造林技术可大幅度提高成活率。1)集水造林。依据造林地坡度大小,采用水平沟、鱼鳞坑和反坡梯田等蓄水工程造林。无论采用哪种整地形式,都力求塄埂坚实牢固,达到“三光一硬,脚踩不 Wubu Shaanxi Province is located in the rocky mountainous area along the Yellow River. The mountainous area accounts for more than 90% of the total. The natural features such as steep mountains and steep mountains and mature earths walking each year become the main constraints to improve the survival rate of jujube trees. After testing, the following integration of drought afforestation technology can greatly improve the survival rate. 1) catch water afforestation. According to the slope of afforestation land size, the use of horizontal ditch, fish scale pit and anti-slope terraces and other water projects afforestation. No matter what kind of site preparation form, all strive to 塄 埂 solid and firm, to achieve ”three light and one hard, do not step on the foot
