The effects of living plants and straws of four hyperaccumulator plant species (Siegesbeckia orientalisL., Crassocephalum crepidioides, Galinsoga parviflora and Solanum nigrumL.) on the growth and cadmium (Cd) content of Ziziphus acidojujuba seedlings were studied through intercropping and straw-applying experiments. Compared to the control, the four hyperaccumulator plant species and their straws increased the biomass, photosynthetic pigment contents, antioxidant enzyme activities and soluble protein content of Z. acidojujuba seedlings. The growth of Z. acidojujuba seedlings was increased most significantly by intercropping with G. parviflora and applying S. orientalis straw. Two experiments both reduced Cd content in roots of Z. acidojujuba seedlings, while increased the Cd content in shoots of Z. acidojujuba seedlings. The Cd content in shoots of Z. acidojujuba seedlings increased most significantly when intercropping with G. parviflora and applying C. crepidioides straw. In summary, four living hyperaccumulator plant species and their straws promoted the growth of Z. acidojujuba seedlings while increased the Cd content of the shoots, an outcome not conducive to the remediation of Cd-contamination jujube orchards.
