The effects of intercropping with two ecotypes of Galinsoga parviflora and their post-grafting generations on nutrient uptake of Lactuca sativa were investigated through pot experiment under the cadmium stress. The results showed that intercropping with post-grafting generation of G. parviflora of farmland ecotype as rootstock (FR) had the best effect on increasing P content in L. sativa roots, while intercropping with post-grafting generation of G. parviflora of mine ecotype as scion (MS) could increase the P content in L. sativa shoots most effectively. The root content of K in the monoculture L. sativa was the highest, and the highest shoots K content was found in the L. sativa intercropping with G. parviflora of farmland ecotype (FCK). As far as the grafting method is concerned, intercropping with post-grafting generation of G. parviflora of mine ecotypes are used as scions and farmland ecotypes as rootstocks is more conducive to L. sativa nutrient uptake. Intercropping with MS can increase soil available N and K.
