我们公社位于兴城县的西北部,屈石质山区,土层薄而干旱。以往造林多采用不整地造林或小坑造林法,成活率和保存率较低。为了加速绿化步伐,提高造林质量,在林业先进单位经验的启示下,破因循守旧的保守思想和“懦夫懒汉”世界观,发动群众,大干苦干,大打了植树造林前整地的人民战争,1974年在山坡造林地上于造林前进行了水平带状大垄整地18,500亩。规格是:垄宽1米、长30～50米,垄面活土层厚45～60厘米,外沿高于里沿20～30厘米,垄向沿等高线方向排列,垄距为2米。同年秋季栽植洋槐林,株行距为1×2米或1.5×2米。实践证明,干旱瘠薄山区实行整地造林有利于保持水土,如 Our commune is located in Xingcheng County, northwestern Qu stone quality mountainous areas, thin and arid soil. In the past, most of the afforestation methods were not afforestation or pits afforestation, with low survival rate and preservation rate. In order to speed up the pace of afforestation and improve the quality of afforestation, inspired by the experience of forestry advanced units, they broke the old conservative thinking and the “cowardly lazy man” world outlook, mobilized the masses and worked hard to fight the people’s war before afforestation. Year in afforestation on the hillside in afforestation carried out a horizontal strip of large ridge land 18,500 acres. Specifications are: Ridge width of 1 m, length 30 to 50 meters, the soil layer of living soil layer thickness of 45 to 60 cm, the outer edge of 20 to 30 cm above the ridge, the ridge along the direction of contour lines, ridge spacing of 2 meters . The same year autumn planting acacia forest, spacing of 1 × 2 meters or 1.5 × 2 meters. Practice has proved that arid barren mountain land afforestation helps maintain water and soil, such as
