摘要
用“小直坑回填整地”和“塑料护苗筒坑整地”２种方法，在高寒地区干旱沙地进行樟子松冬季造林试验，不但可充分利用冬闲时间，延长造林季节，还使造林成活率较穴状整地高．春、秋造林成活率提高４０％以上，保存苗成本降低５０％以上．
Using
soil preparation of small perpendicular pit and seedling plastic tube,winter afforestation test of
Pinus sylvestris var.mongolica was carried out.These methods not only used free time and
extended afforestation season,but also improved survival rate.Survival rate in Spring and Autumn
reached above 40%,preserving seedling cost reduced 50%.
