摘　　要：对秃杉1年生实生苗进行根外追肥试验，以不施肥为对照。结果表明：根外迫肥对苗木的高、径生长均有明显的促进作用，追肥5个月苗高达21．3～26．0cm．地径为0．39～0．47cm,而对照则分别为17．7cm和0．27cm。不同肥料对苗木高、地径生长的促进作用差异显著，其中大肥王、复合肥对苗高、地径的增长效果较好，其苗高分别比对照增加55．45％、74．55％，地径分别比对照增加167％、141．6％。在秃杉实生苗培育生产上可首选复合肥进行根外追肥。Foliage top dressing was conducted on 1-year-old Taiwanic flousiana Gausses seedling, the results showed that foliage top dressing had the evident promoting effect on the seedling height and diameter growth, the height reached 21.3-26.0 cm after 5 months long of foliage top dressing, the ground diameter reached 0.39-0.47 cm, whereas the above of control reached 17.7 cm, the latter of control reached 0.27 cm. There was significant difference between various fertilizers＇ promoting effects on seedling height and ground diameter growth, the king fertilizer and compound fertilizer had relatively big growth effects on the seedling height and ground diameter growth, the seedling heights were 55.45 % and 74.55 % higher than the control, respectively, the ground diameters were 167 % and 141.6 % higher than the control, respectively. The compound fertilizer might be firstly applied to conduct the foliage top dressing during T. flousiana Gausses seed plants culture and production.
