摘要
该文以3～6a生南方红豆杉为研究对象,对林分树高、地径、冠幅、根重、杆重及枝叶重等性状进行研究分析,结果表明:南方红豆杉的根、杆重所占比例随栽培年龄的增大而增加;对于3a生红豆杉遮阴50%为适宜;适于生长在土壤肥厚、有机质含量多、土壤疏松、湿润、排水良好的壤土,并且施复合肥、钾肥、磷肥对红豆杉生长最适宜;根系发达,冠幅完整的壮苗造林成效好。
This paper took 3~6 year-old Taxus chinensis Var.mairei as the research object,in order to research and analysis on the forest stand height,collar diameter,crown diameter and the weight of root,rod and leaves.The results showed that： the weight proportion of Taxus chinensis roots,rods increased with increasing age of cultivation;3 years old Taxus chinensis shade 50% as appropriate;the loam of hypertrophy,organic content,loose,moist,well drained and fertilizer,potash fertilizer,phosphate fertilizer is suitable for growth;strong seedling afforestate a good effect,which have developed root system and complete crown diameter.
