摘要
采用２５ ｍ带宽和１５ ｍ带宽、３０ ｍ、２０ ｍ、１０ ｍ孔径斑块抚育伐．对红松造林试验进行景观处理、栽植了容器苗和裸根苗两种类型的红松苗．并对各种处理方式下红松幼苗的生长、成活率和缓苗情况进行了动态、定位研究。结果表明：红松容器苗造林后生长和成活都优于裸根苗．而且育苗周期缩短两年；红松容器苗采用窄带和中孔径斑块、裸根苗采用带状和林下造林效果较好；带状造林后防寒和裁冠措施没能显著提高造林后幼苗成活率；红松景观造林试验地可供长期定位研究。
Adopting landscape treatment, the planting experiment was carried out using bare-root and container seedlings after felling in two second-growth stands in belt, with width of 25 m and 15 m, and in patch. with radii of 30 m. 20 m and 10 m. The growth. survival rate and recovery status of Korean pine seedlings under different treatments were observed. Result shows that. compared to bare-root seedlings. container seedlings. which have shortened nursery period of 2 years. have better performance both in growth and survival rate. Container seedlings planted in narrow belt and in mid-radius patch and bareroot seedlings planted in belt and under trees have good results. Anti-frost measures and crownshearing treatment did not have noticeable improvement in seedling growth and survival rate. This landscape planting experiment will facilitate long term study of Korean pine.
