Establishment of climate characteristic curve of medicinal plant Fritillaria cirrhosa D. Don (Fritillaria cirrhosa D. Don)

Abstract

The invention relates to establishment of a climate characteristic curve of a medicinal plant Fritillaria cirrhosa D. Don, and discloses a method for analyzing and establishing a climate characteristic curve of Fritillaria cirrhosa D. Don, so as to attempt to find climate characteristics of main producing areas of the Fritillaria cirrhosa D. Don. The method comprises the following steps: F1, determining distribution points of the Fritillaria cirrhosa D. Don in China according to the Chinese virtual herbarium and literature review; F2, obtaining data of 9 climatic factors of the distribution points of the Fritillaria cirrhosa D. Don; F3, obtaining ecological factors having a relative large contribution rate on the geographical distribution of the Fritillaria cirrhosa D. Don and constituting climate characteristic parameters of distribution areas of the Fritillaria cirrhosa D. Don according to a factor analysis method and functional rules of the ecological factors on plants; and F4, calculating a variation range of the climate characteristic parameters, and establishing the climate characteristic curve of the Fritillaria cirrhosa D. Don in these areas. According to the method for establishing the climate characteristic curve of the Fritillaria cirrhosa D. Don disclosed by the invention, the characteristic extraction and selection thought and method in mode recognition are used for the first time for quantitatively evaluating the climate demands of the Fritillaria cirrhosa D. Don in the whole country, so as to give the reasons why the quality of famous-region drugs is high.

Description

technical field [0001] The invention relates to the field of establishment of climate characteristic curves of the medicinal plant Fritillaria fritillaria, in particular to the definition of the climate characteristics of Fritillaria fritillata, the data form used to reflect the climate characteristics, the construction method of the climate characteristics and the like. Background technique [0002] Fritillaria cirrhosa D.Don is a well-known commonly used traditional Chinese medicine, which has the effects of moistening the lungs and resolving phlegm, relieving cough and asthma, and clearing away heat. Fritillaria is mainly distributed in East Asia, among which China, India, Nepal and other countries are its main distribution areas. The growth, development and distribution of plants are closely unified with the environmental conditions, while Fritillaria is mainly distributed in Sichuan, Tibet and Yunnan, indicating that the environment in these areas is extremely suitable ...

AI Technical Summary

Problems solved by technology

The growth, development and distribution of plants are closely unified with the environmental conditions, while Fritillaria is mainly distributed in Sichuan, Tibet and Yunnan, indicating that the environment in these areas is extremely suitable for the growth of Fritillaria, and climatic factors have great influence on the formation of Fritillaria. It plays an important role. In the past, most of the researches were to compare the content of Fritillaria fritillatus in different producing areas. There has been no clear data on the climate characteristics of the growth area of ​​Fritillaria fringata.
