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。
25 m bandwidth and 15 m bandwidth, 30 m, 20 m, 10 m aperture planing tending. The pine plantation and afforestation were carried out with landscape treatment and two types of container seedlings and bare root seedlings were planted. The growth, survival rate and seedling growth of Pinus koraiensis seedlings under various treatments were studied dynamically. The results showed that the growth and survival of Pinus koraiensis seedlings after afforestation were better than bare root seedlings. And the seedling cycle was shortened by two years. The seedlings of Korean pine were narrow-band and mesoporous. The bare-rooted seedlings were better with banded and undergrowth afforestation. The cold-tolerant and cut-crown measures did not significantly improve the survival rate of seedlings after afforestation. Pine plantation afforestation experiment for long-term positioning.
