Abstract In order to clarify the soil nutrients and comprehensive fertility of Panax ginseng cultivated in farmland and provide reference for rational planting ginseng, 14 soil nutrient indexes of 42 soil samples from 14 counties and cities in ginseng producing areas were studied, the soil fertility status was comprehensively evaluated by principal component analysis and fuzzy mathematics membership function model, and the comprehensive index value (IFI) of soil fertility was calculated. The results showed that the contents of soil organic matter, total nitrogen, total phosphorus, alkalihydrolyzed nitrogen, available potassium, available iron and manganese were sufficient. The average of IFI value of soil fertility index of farmland ginseng in field producing area was 0.71, and most of them were in gradeⅠand grade Ⅱ. Among them, the soil fertility accounted for 66.67% of the sampling area, and the overall level of soil was good.
