摘要
通过不同坡位、距林缘远近、采用防寒和裁冠处理,对红松容器苗和裸根苗的造林质量的影响进行了试验研究,结果表明:坡位和距林缘距离对生长量影响不大;坡上死亡率裸根苗高于容器苗4个百分点;距林缘距离与裸根苗死亡率无关;带状造林不需要防寒和裁冠处理。
Effect of different slope positions, distance to the forest edge, winter protection ＆ crownshearing treatment on af- forestation quality of container seedlings ＆ truncated plant of Pinus koraiensis were studied. Result shows that ： slope posi- tion ＆ distance to the forest edge has little effeet on the growth;upslope mortality of truncated plant is 4% higher than that of container seedlings ; distance to the forest edge has no correlation with mortality of truncated plant; winter protection ＆ erownshearing treatment are not required for zonal woodland.
