Īn L, Pan Y, Wang Z, Zhu C (2011) Heavy metal absorption status of five plant species in monoculture and intercropping. From the antioxidant system, the performance of the three seedlings intercropped together is better than the two however, the accumulation of Cd shows the opposite trend, and the participation of cabbage in the intercropping is relatively conducive to reducing the Cd content in the edible parts.Īi S, Guo R, Liu B, Ren L, Naeem S, Zhang WY, Zhang YM (2016) A field study on the dynamic uptake and transfer of heavy metals in Chinese cabbage and radish in weak alkaline soils. When intercropping with pakchoi or lettuce separately or together, it promoted the accumulation of Cd in radish root when intercropping with pakchoi, the value of TF was the smallest. At the same time, root or shoot bio-concentration factors also performed the same trend, and TF was the smallest and less than 1 however, the TF of lettuce is greater than 1.
When intercropped with pakchoi and lettuce, the Cd content in the roots and shoots of pakchoi is higher and lower, respectively. Intercropping increased the soluble sugar and proline content in the lettuce seedlings, while those in the radish and lettuce seedlings reduced or had no significant effect. When three seedlings were intercropped together, the antioxidant enzyme activity of pakchoi, lettuce, and radish increased and the content of malondialdehyde decreased, except that the superoxide dismutase activity of radish is inferior to the value of radish and pakchoi intercropping. Intercropping is not conducive to the accumulation of chlorophyll and biomass content of pakchoi, lettuce, and radish. ramosa Hort.), and radish ( Raphanus sativus L.) seedlings under monoculture, mutual intercropping of two or three varieties.
This study investigated the physiology and cadmium (Cd) content of pakchoi ( Brassica chinensis L.), lettuce ( Lactuca sativa L. Intercropping can affect the growth and elemental absorption of vegetables.
