Abstract:: Cultivation of Panax ginseng in farmland is being implemented in most areas,because of destruction of the environment by the Panax ginseng of cutting forest.Therefor,people have explored new channels for the development of ginseng,and have also achieved great results,and many scholars have made the field ginseng more and more popular through the improvement and research of farmland soil.The standard of soil evaluation has a great effect on the standardized production of Panax ginseng that the growth of Panax ginseng has a very high requirement for soil,but China still does not have a standard soil fertility index.This study reviewed that the suitable for the growth of farmland Panax ginseng of approximate range value of various fertility indexes by summarize the research results at china and abroad.The results showed that the pH 5.0-6.0；EC value 100-200 μS·cm-1，organic matter 16-30 g·kg-1，total nitrogen 1.6-2.8 g·kg-1，effective nitrogen 10-150 mg·kg-1，total phosphorus 0.1-0.7 g·kg-1，available phosphorus 20-50 mg·kg-1，total potassium 5.0-12 g·kg-1，available potassium 200-300 mg·kg-1.
