Abstract: Capsicum annum L.,Solanum nigrum L.and Amaranthus hypochondriacus L.were used as the test materials, and the field experiments were conducted through intercropping Capsicum annum L.with Solanum nigrum L.and Amaranthus hypochondriacus L.respectively.The effects of Capsicum annum L.intercropping with different accumulators on the uptake and accumulation of cadmium（Cd） in Capsicum annum L. were studied, in order to provide reference for the safe production of Capsicum annum L..The results showed that intercropping with Amaranthus hypochondriacus L.and Solanum nigrum L.had no significant effect on the yield of Capsicum annum L.,and there was no significant difference in fruit number per plant, yield per plant and per 667 m~2 under different intercropping patterns.Intercropping with Amaranthus hypochondriacus L.and Solanum nigrum L.could reduce the Cd content of Capsicum annum L.roots, stems, leaves and fruits, and the effect of intercropping with Solanum nigrum L.were better than that of Amaranthus hypochondriacus L..Intercropping with accumulators could reduce the transport ability of Capsicum annum L.leaf and root to fruit, intercropping with Solanum nigrum L.could significantly reduce the Cd accumulation of Capsicum annum L.fruits.The content of Cd in roots, stems and leaves of intercropping Solanum nigrum L.was higher than that of intercropping Amaranthus hypochondriacus L..Intercropping with Solanum nigrum L.had a better effect on soil Cd reduction..In summary, intercropping with Solanum nigrum L.could reduce the absorption and accumulation of Cd by the fruits of Capsicum annum L.,which was beneficial to the safe production of Capsicum annum L..
