Soil physicochemical properties and fungal communities are pivotal factors for continuous cropping of American ginseng (Panax quinquefolium L.). However, the response soil to replant disease has not yet been studied. High-throughput sequencing analyses were undertaken investigate difference environmental driver in new old fields; extent fields closely related changes was also determined. Results indicated that an field more sensitive environment than those a field, mainly driven by organic matter (SOM), available phosphorus (AP), potassium (AK). Notably, healthy plants may influence actively recruiting potential suppressive agents such as Amphinema, Cladophialophora, Cadophora, Mortierella, Wilcoxina. When these key groups members depleted, possibly declined, increasing abundance pathogens. used grow contained variety pathogens, including Alternaria, Armillaria, Aphanoascus, Aspergillus, Setophoma, Rhexocercosporidium. Additionally, micro-ecological affecting outbreaks included strengthening competition relationships, weakening cooperation change trophic strategies among communities.
