摘要
通过连续3a对琅琊榆播种苗苗高、地径生长量的调查,以及对天然次生林不同透光度下萌蘖苗生长、生理分析,模拟出珍稀树种琅琊榆苗期生长模型;在此基础上,将苗木年生长过程划分为3个不同的生长阶段;并探讨了光影响苗木生长及分布的内在机理.
Based on investigation
on growth and physiological index of the sowing seedlings and the sprout tillers of Ulmus
chenmoui, several mathematical models for their growth were developed The annual growth
process was devided into three stages And then,the paper analysed the internal machanisms of
that light effected on distribution and growth of the seedlings
