    ObjectiveTo find the status and changes of the soil nutrients in rhizosphere of Atractylodes lancea.MethodTotal nitrogen (total N), available K, available P, organic matter (ORG), available nitrogen and pH in rhizosphere soil of the wild growing A. lancea in 3 sites, MS, LT and MFS, and the cultivated ones with different ages in LT were detected.ResultThe contents of total nitrogen (total N), available K, available P, organic matter (ORG), available nitrogen and pH value in rhizosphere soil were significant different between MS, LT and MFS (P < 0.01). The results of the 6 detected parameters in MS were the lowest, in MFS were the highest and in LT were in the middle. The total N, ORG and available N in the cultivated A. lancea were lower than that in the wild ones (P < 0.01) and available P and pH value in the cultivated A. lancea were higher than that in wild ones (P < 0.01) and there was no difference in available K between the wild and cultivated ones in LT (P > 0.05); 3 available P in rhizosphere soil of the two years old A. lancea were higher than of the one year old A. lancea (P < 0.01) and there were no difference of total N, ORG, available N, available K and pH value in rhizosphere soil of A. lancea between one year and two years plant (P > 0.05).ConclusionIt is indicated that the growth of A. lancea in Mt. Mao is faced nutrient stress.
