通过对5a生樟子松移植桶苗、容器苗及2a生裸根苗的造林成活率、保存率、根系生长及树高生长的调查、分析得出,用移植桶苗及容器苗造林,比用裸根苗成林速度快2～4a,成活率及保存率也明显提高;经ABT生根粉、HRC保苗剂等处理过的2a生樟子松,成活率与用容器苗及移植桶苗的成活率相近,造林成本比较低。因此,提倡因地制宜,在不同的立地条件及生产条件下,选用不同的苗木造林。
Based on the investigation of 5-year-old Pinus sylvestris plantation seedlings, container seedlings and 2a bare root seedlings, the survival rate, survival rate, root growth and tree height growth were analyzed. The results showed that with transplant seedlings and container seedlings, The survival rate and preservation rate of bare rooted seedlings increased rapidly from 2 to 4a, and the survival rate of 2a-Pinus sylvestris var. Mongolica 2a-treated seedlings treated with ABT, Similar, afforestation costs are relatively low. Therefore, advocating measures to local conditions, in different site conditions and production conditions, choose different seedlings afforestation.
