泽泻有效成分与生态因子的关系

Relationship Between Effective Component of Alisma orientalis(Sam) Juzep and Ecological Factors

通过相关性和灰色关联分析方法系统研究了泽泻有效成分与生态因子之间的关系.相关性分析表明泽泻药材有效成分与其生长期内的平均温度呈负相关(r=-0.724 5),与空气平均相对湿度呈正相关(r=0.740 0);灰色关联分析表明泽泻生长期内平均相对湿度是影响泽泻中2,3-乙酰泽泻醇B含量的主导气候因子,并且土壤中的钾元素对泽泻中2,3-乙酰泽泻醇B的含量影响最大.结合分析江苏地区的气候及土壤因子以及引种后的泽泻药材质量,证明江苏地区适宜泽泻的生长,泽泻引种江苏是切实可行的.

The relationship between effective component of Alisma orientalis （Sam） Juzep and ecological factors were analyzed by using correlation and grey correlation analysis. Correlation analysis indicated that the effective component of Alisma orientalis showed negative correlation with average temperature （ r = - 0. 724 5 ） , and positive correlation with average relative humidity（ r =0. 740 0）. Grey correlation analysis showed that average relative humidity was the dominant climatic factor and the content of kalium in soil affected most on the content of 2,3 -acetyl alisol B. The study of climatic factors and soil factors in Jiangsu area and the quality of the introduced medicinal material found Jiangsu suitable for the growth of Alisma orientalis, which demonstrated that it is feasible to introduce Alisma orientalis into Jiangsu.
