[Objective] The effects of two ecotypes(farmland and mining) of accumulator plants intercropping with cherry seedlings on soil enzyme activity under cadmium stress were examined in order to provide the reference for cherry production in cadmium pollution area. [Methods] Tianxin cherry and Naweng cherry were intercropped with two ecotypes of cadmium accumulator Conyza canadensis

Solanum nigrum and Digitaria sanguinalis

respectively

and the soil catalase

urease and invertase activities were determined. [Results] When Tianxin cherry intercropped with mining ecotype of D. sanguinalis

the soil catalase and urease activities reached to the highest values

which were improved by 41.07% and 57.53% than monoculture of Tianxin cherry

respectively. When Naweng cherry intercropped with farmland ecotype of C. canadensis

the soil catalase activity reached to the highest value

and the soil urease activity reached to the highest value when intercropped with mining ecotype of D. sanguinalis. When cherry seedlings intercropped with two ecotypes of accumulator plants

only Tianxin cherry intercropping with farmland ecotype of C. canadensis

Naweng cherry intercropping with mining ecotype of D. sanguinalis and Naweng cherry intercropping with farmland ecotype of D. sanguinalis improved the soil invertase activity. [Conclusion] Under cadmium stress

the soil enzyme activity of cherry could be improved by intercropping

and the best material was mining ecotype of D. sanguinalis

and followed by farmland ecotype of C. canadensis.
