- 摘要:
- 以红花玉兰1 a生播种苗为试材，研究了红花玉兰物候期特性和年生长规律。结果表明：播种后第2周，幼苗开始露出地面，出苗期长达93 d，第189天（10月下旬）地径生长进入慢速生长期时，幼苗开始形成冬芽，12月初幼苗开始落叶;根据Logistic生长曲线，地径和苗高的生长曲线均呈“S”型，地径的快速生长期（播种后第50~189天）长于苗高（播种后第84~150天），但地径和苗高每15 d的最大和次大净增量均发生在7月底至8月底;同时发现，遮荫环境更适于红花玉兰1 a生播种苗的生长。
- Abstract:
- Taking one-year-old Magnolia wufengensis L.Y.Maet L.R.Wang seedlings as test material，the phenological observation and annual growth dynamics were studied.The results showed that seeds of M.wufengensis L.Y.Maet L.R.Wang had sprout into seedlings after two weeks since sown；the emergence period was long for 93 days.And winter buds were formed on the 189thday(in late October)，when the growth of diameter stepped into the slow growth period.Until early December，leaves began to drop.Based on the Logistic curves，the growth curves of diameter and height were shown as ‘S’，though the rapid growth period of diameter(during days from the 50thto 189thsince sown) was longer than height(during days from the 84thto 150thsince sown)，the first and second net increment for each 15 days were occurred from late July to late August.It was also found that shade environment was better for the seedling growth.
