Effects of the Continuous Cropping and Soil-borne Diseases of Panax ginseng C. A. Meyer on Rhizosphere Soil bacterial Communities

Continuous cropping and soil-borne diseases affect soil microbial diversity and structure, which is the main factors caused continuous cropping obstacle of ginseng. This study was carried out to explore the response of bacterial community of ginseng rhizosphere soil to continuous cropping and soil-borne diseases. Therefore, we took the woodland soil without planting ginseng as control to study these changes. The results showed that continuous cropping and soil-borne diseases significantly affected bacterial communities. Using MiSeq high-throughput sequencing, we found the alpha diversity and number of bacterial communities significantly changed after continues cropping and soil-borne diseases. In a word, this study expounded the effects of continuous cropping and soil-borne diseases on soil and provided a theoretical basis for the alleviation of soil-borne diseases of ginseng.
