金银花道地与非道地产区地质背景及土壤理化状况分析

目的:研究金银花道地性与其地质背景系统(GBS)、土壤理化状况的关系。方法:比较5个不同产区同一种质金银花的地质背景系统(GBS),分析土壤理化状况。结果:道地金银花的分布受GBS制约,主要分布于北纬34°-36°、东经113°-118°的大陆性暖温带季风性半干旱气候区内。结论:道地金银花产区土壤受其成土母质影响;道地金银花最适合的土壤类型是中性或稍偏碱性的砂质壤土,且要求土壤的交换性能较高,可作为其道地性的特征之一。

Analysis on the Geologic Background and Physicochemical Propertiesof Cultivated Soil of Flos Lonicerae in the Geo-authenticand Non-authentic Producing Areas

Objective: To study the relationship between the Geo-authentic and Geologic Background System (GBS) and physicochemical properties of cultivated soil in the Flos Lonicerae. Method: The analysis on the physicochemical properties of cultivated soil, the geologic background system in 5 producing areas of Flos Lonicerae was compared. Result: The distribution of genuine Flos Lonicerae was restricted by GBS, which was mainly restricted in the temperate continental monsoon semi-arid climate zone between north latitude 34-36° and east longitude 113- 118°. Conclusion: The most suitable soil for the genuine Flos Lonicerae is the neutral or weak alkali sandy loamy soil with higher ion exchanging capacity, and the soils from those producing areas are determined by soil-forming parent materials.
