摘　　要：对2年生天台鹅耳枥地上营养构件(树干、侧枝、叶)的生长发育过程进行研究的结果表明,苗高和地径生长均表现为"慢-快-慢-快"的趋势,呈双峰曲线,苗高生长高峰为6月1日和8月19日,地径生长高峰为4月15日和7月15日。侧枝生长先快后慢,呈"S"型曲线,侧枝生长高峰期在5月份。叶片生长盛期有两个,分别是展叶初期之后以及5月份,长得早的叶片叶形较小。试验表明在天台鹅耳枥幼苗培育过程中,在温度过高时多浇水,当光强过大时注意遮荫;在快速生长期注意施肥,以促进生长。A systematic study was conducted to explore the growth and development of vegetative components(trunk,lateral branch and leaf)on the ground of the two-year-old C.tientaiensis,it began to grow for seedling and ground diameter,which showed the bimodal trend of“slow-fast-slow-fast”.The peak of seedling height growth was in June 1 and August 19 while it was in April 15 and July 15 for diameter growth.Lateral branches grew faster at the beginning but slower subsequently,showing the“S”curve;and the growth peak of the lateral branches was in May.The two growth periods of leaves were at the early stage of the stretching leaves and in May,but leaves that grew early were smaller.The experimental results indicated that when the seedling of C.tientaiensis cultivation process,watered more when the temperature was too high,and shaded more when the light was too strong;and soil should be fertilized to promote its growth during the rapid growth.
