青松岭大队位于建平县东北部,是个纯山区,气候干旱,全年降水量为500毫米左右,而且降水量的70-80%以上都集中在6、7、8三个月份。土壤干旱瘠薄。这个大队广大革命群众、革命干部响应毛主席“绿化祖国”、“实行大地园林化”的伟大号召,大搞植树造林,取得了一定的成绩。并于1969年雨季在平均土层厚20厘米,并含石砾,植被盖度不大的三个不同坡向上用油松百日苗造林试验获得初步成功,平均成活率达到88%(见表1)。

Qing Songling Brigade is located in the northeast of Jianping County, is a pure mountainous area, arid climate, the annual precipitation is about 500 mm, and more than 70-80% of precipitation are concentrated in 6,7,8 three months.
