[Study on wild tending of Chrysanthemum indicum].

ABSTRACT

To provide theoretical basis for the formation of Chrysanthemum indicum resource and quality,the differences in biology,ecology,yield and quality of Ch. indicum population in the wild tending,the cultivated and the wild were analyzed and compared in this study. The results showed that in the aspect of biology,there was no significant difference between the condition of wild tending and cultivated Ch. indicum at the height of plant,both were significantly higher than wild Ch. indicum. In the aspect of ecology,in the condition of wild tending is less likely to occur water logging than cultivated Ch. indicum. In the condition of wild tending is less likely to occur plant diseases and insect pests than Ch. indicum in the condition of wild. In the aspect of production,the average output of the sample of the condition of wild tending was significantly higher than that the condition of artificial cultivation and wild quadrat. There was no significant difference between the three kinds of condition on the traits of capitulum dichasium,the content of buddleoside of the wild tending Ch. indicum was significantly higher than that of 0. 80% required by the Chinese Pharmacopoeia( 2015 edition). Therefore,the artificial supplement and the appropriate artificial management of wild tending is a mode of production to increase the population density of Ch. indicum and obtain high quality and high yield medicinal materials.
