摘　　要：张广才岭上部寒温地带生长的原始云冷杉林，经采伐后迹地次生演替成为亚高山禾草草甸。本研究应用新技术５ＺＰ—１０型化学灭草专用喷雾器，在草地喷洒灭生性除草剂进行整地和抚育幼林，其结果：灭草效果在９５％以上；抚育后的云杉幼林年平均高生长量是人工刀抚２８２％，落叶松是人工　　刀抚１９２％；幼林保存率由１０％提高到８０％以上，并使草甸化的迹地；恢复云冷杉林的时间大大缩短，为草甸化迹地天然和人工更新提供了有效途径。There were virgin dragon spruce and faber fir forests in upper frigid and temperate zone in Zhangguangcai Mountain.After cutting,the site became sub-alm through secondary succession.5ZP-10 type weeding sprayer were used to spray weedicide to prepare site and tend young growth. The result was above 95%.The height growth of young dragan spruce forest was on the average 282%as much as that with commoon tending.The larch was 192%.The rate of young forest was increased from 10 % to above 80%.
