摘 要:通过对3年生樟子松容器苗与裸根苗定植后的成活率、保存率、生长量、生产管理和投资费用对比分析,提出了定植容器苗大大优于裸根苗,定植成活率和保存率分别达到96.3%和99%。与裸根苗相比,容器苗造林每667 m2可节约投资764元。特别是在风沙、干旱、瘠薄的榆林沙区,由于风沙侵蚀严重,立地条件低劣,更应提倡并推广使用容器苗。Survival rate,preservation rate,growth,production management investment cost of three-year-old container seedlings of Pinus sylvestris var.mongolica with bare root seedlings after planting were analyzed.It proposed that field-planting container seedlings are much optimal than bare-rooted seedlings,planting survival preservation rate are 96.3% 99% respectively.Compared with bare root seedlings,afforestation by container seedlings can save investment by 764 yuan per 667 m2.Container seedlings should be promoted in the sandy,arid barren Yulin sandy area due to its severe wind and sand erosion,poor site conditions.
