The cultivation methods determine the production and remediation capacity of crops in heavy metal-contaminated farmland. This study investigated the effects of seedling establishment methods and relay intercropping with Chinese milk vetch (Astragalus sinicus L., CMV) on the production and remediation of Napier grass (Pennisetum purpureum Schum, NG) in cadmium (Cd)-contaminated farmland in southern China. The results showed that the regrow NG (RNG) had higher aerial part yield because of its well-developed roots and larger tiller numbers, which ...
