气候因子对狭叶四照花幼苗年生长节律的影响

Effect of Climatic Factors on Annual Growth Dynamics of Dendrobenthamia angustata

应用灰色系统理论中的关联分析方法,对1年生狭叶四照花苗高、地径生长量与气候因子间的关系进行了定量分析,结果表明影响其苗高、地径净生长量的主导因子分别是旬平均气温和旬降水量。

In this paper the various climatic factors affecting the growth of height and diameter at ground of one year seedling of Dendrobenthamia angustata were quantitatively analyzed through the application of the grey-function scale associative method. And the result showed that the main factors were average temperature and rainfall in each ten-days.
