野生柳兰生长与主要气候因子关联分析

摘要

为明确柳兰生长的限制因素,科学开发柳兰规模化种植技术,在实地监测内蒙古锡林郭勒野生柳兰全生育期生长情况的基础上,应用灰色关联度分析方法对其与主要气候因子的关系进行研究.结果表明,对野生柳兰植株生长量而言,4个主要气候因子的关联度从大到小依次为降水量、相对湿度、光照强度、气温,可见降水量是影响野生柳兰植株生长量的主导因子;对野生柳兰植株叶片数量而言,4个主要气候因子的关联度从大到小依次为相对湿度、气温、光照强度、降水量,可见相对湿度是影响野生柳兰叶片数目的主导因子;对野生柳兰植株叶片长度而言,4个主要气候因子的关联度从大到小依次为光照强度、气温、相对湿度、降水量,可见光照强度是影响野生柳兰最长叶长的主导因子.%In order to clarify the limiting factors for the growth of Epilobium angustifolium,and to develop the scale planting technology scien-tifically,on the basis of the field monitoring of the growth of wild Epilobium angustifolium in Xilingol of Inner Mongolia,the relationship be-tween the main climatic factors and the growth of wild Epilobium angustifolium was analyzed by using the gray relational degree. The results showed that:for the amount of growth of wild Epilobium angustifolium,the correlations of the four major climatic factors from the largest to the smallest were precipitation,relative humidity,light intensity and air temperature,it could be seen that the precipitation was the dominant factor affecting the growth of wild Epilobium angustifolium plants;In terms of the number of wild Epilobium angustifolium plant leaves, the correla-tions of the four major climatic factors from the largest to the smallest were relative humidity,air temperature,light intensity and precipitation, it could be seen that the relative humidity was the dominant factor affecting the number of leaves of wild Epilobium angustifolium.In terms of leaf length of wild Epilobium angustifolium plants,the correlations of the four major climatic factors from the largest to the smallest were light intensity,temperature,relative humidity and precipitation,it could be seen that the light intensity was the dominant factor affecting the longest leaf length of wild Epilobium angustifolium.
