Abstract: In order to understand the soil condition of peanut farmland in Dabie mountainous area of Hubei province, 88 samples of soil were tested and analyzed from 7 main peanut-growing counties and cities, different farming modes and soil types in the Dabie mountains of Hubei province. The results showed that the peanut arable land in the Dabie mountains of Hubei province was generally weakly acidic, and the average soil pH was 6.12, which was a slight variation; The content of total soil carbon was low, and the content of total soil nitrogen, available potassium, and available phosphorus were generally higher; The soil alkalinity nitrogen content was overall low; The soil pH of the peanut farmland with different planting methods was weakly acidic, and the soil nutrient of the peanut farmland in rotation was better than that of continuous cropping in winter, but there was no significant difference; The particle size composition of peanut farmland soil in Dabie mountain area of Hubei province was basically coarse powder>sand>clay.
