红松容器苗造林技术

针对我国东北林区红松更新造林难度大、成活率和保存率低等实际问题，采用红松容器苗和自行研制、配套的苗木集装运输设备及植苗器具，进行不同季节的更新造林试验。结果表明：造林后的前两年，容器苗无缓苗现象，幼树的高、径生长量明显大于裸根苗，大幅度提高了造林成活率与保存率，从而使幼林尽早郁闭。解决了干旱瘠薄的陡坡地段红松造林不易成活的难题。容器苗造林技术的推广作用，结束了我国北方高寒林区单一裸根苗造林的历史。

Study on Container Seedling Planting Techniques of Korean Pine

Manual regeneration of Korean pine is difficult, how to improve the survival rate and preserving rate is a tough problem. By using container seedlings of Korean pine and self-invented equipment for transporting and planting the container seedlings, planting experiment has carried out in different seasons of year. The result shows, compared with bare-root seedlings, container seedlings need no seedling-recovery, and have better height and diameter growth in the first 2 years after planting. Using container seedlings can improve the survival rate and preserving rate remarkably. Thus the plantation will have early crown closure. This technique can solve the problem of low survival rate in the steep sites, which are dry and poor. The extended application of container seedling will end the situation of regeneration using solely bare-root seedling in the north China forest areas, and has a good economic and social benefit.
