- Abstract
The pot experiment was conducted to study the effects of lettuce intercropping with positive and negative grafting generations of two ecotypes (farmland and mining) of cadmium (Cd) hyperaccumulator plant Galinsoga parviflora on soil enzymes activity. The positive grafting: the rootstock was mining ecotype of G. parviflora (post generation was defined as mining-rootstock) and the scion was farmland ecotype of G. parviflora (post generation was defined as farmland- scion); the negative grafting: the rootstock was farmland ecotype of G. parviflora (post generation was defined as farmland-rootstock) and the scion was mining ecotype of G. parviflora (post generation was defined as mining-scion). The results show that only lettuce intercropping with mining-scion significantly increased the soil invertase activity, soil urease activity and soil catalase activity compared with the monoculture of lettuce. Therefore, intercropping lettuce with mining-scion could improve the ecological environment of Cd-contaminated-soil.
