摘要
通过logistic方程对糙叶杜鹃一年生苗的苗高和地径生长曲线进行拟合,总结出苗期生长发育规律,为其园林应用、保护和开发提供理论依据。结果表明:logistic方程对糙叶杜鹃一年生苗苗高和地径生长曲线的拟合相关性极显著,苗高和地径生长增量呈现出明显的"慢-快-慢"节律,苗高和地径的生长可分为出苗期、生长初期、速生期和生长后期,苗高的速生期在7～10月,地径的速生期在7～11月。同时还对苗期管理进行了探讨。
The plants of Rhododendron scabrifolium Franch is excellent materials of gardening. The growth rule of 1 a seedlings of Rhododendron scabrifolium Franch was studied by Logistic equation, then provided theoreti- cal basis to garden, protection and exploitation. The conclusion showed as follows, the height and diameter growth increments of 1 a seedling had slow-fast-slow rhythm. The height increments increased quickly from July to October, The peak of diameter growth appeared later than height, the diameter growth was increased quickly from July to November. The growth process of height and diameter were imitated suitable by logistic equation. Then the seedling control was discussed.
