英文摘要An effective strategy for the safe utilization of Cd-contaminated soil involves the cultivation of crop varieties with low Cd accumulation in conjunction with a hyperaccumulator such as Hylotelephium spectabile. . In this study, the peach cultivar 'Lvhuajiu' was intercropped with two ecological types of H. spectabile, , 'Liaoning (LN)' and 'Hebei (HB)', to explore plant Cd uptake and rhizosphere soil properties. The results revealed that under pot inter- cropping conditions, the roots of the 'Lvhuajiu' peach tree engaged in nutrient competition, which increased biomass production. A maximum of 68.02% reduction in Cd content was observed in peach tree roots under open intercropping with H. spectabile LN. H. spectabile absorbed more available Cd under intercropping, and LN had a higher Cd absorption capacity than HB. The removal efficiency under restrictive intercropping (0.34%-0.50%) was slightly lower than that under open intercropping (0.62%-0.67%). Intercropping systems were highly abundant in Proteobacteria, , Acidobacteria, , Bacterodietes, , and Actinobacteria, , which are essential for the elimination of Cd and cycling of nutrients. Furthermore, the field experiment showed that peach and H. spectabile inter- cropping could achieve a 4.11% removal efficiency per year under water-soluble chitosan addition. Besides, Cd concentrations in the peaches under all treatments remained below the national food standard of 0.05 mg center dot kg-- 1 . In conclusion, intercropping peaches with H. spectabile facilitates the safe utilization of Cd-contaminated soil by modifying rhizospheric soil properties, underscoring its considerable potential for a wide range of applications.
