The contamination of orchard by cadmium (Cd) has recently increased in severity. To decrease the Cd content in fruit tree, a pot-based experiment was conducted to study the effects of intercropping with two species ( and ) on the growth and Cd accumulation of seedlings. The data revealed that intercropping with two species significantly increased the biomass, photosynthetic pigment contents, antioxidant enzyme activities, and soluble protein contents of seedlings under Cd stress condition. The intercropping significantly decreased the Cd content in seedlings. However, the intercropping significantly decreased the and biomasses, while increased the Cd content and accumulation in the roots and shoots of two species, and the Cd uptake by was lower than that of . Therefore, intercropping with these two species, especially , may promote the growth and decrease the Cd content in .
果园土壤中镉（Cd）的污染近来日益严重。为降低果树中 Cd 的含量，采用盆栽试验研究了两种（和）间作对 Cd 胁迫下实生苗生长和 Cd 积累的影响。结果表明，与两种间作相比，显著增加了 Cd 胁迫下实生苗的生物量、光合色素含量、抗氧化酶活性和可溶性蛋白含量。间作显著降低了实生苗中的 Cd 含量。然而，间作显著降低了和的生物量，同时增加了两种间作的根和茎中的 Cd 含量和积累，且对 Cd 的吸收低于。因此，与这两种间作，特别是间作，可能会促进实生苗的生长并降低其 Cd 含量。
