If that piece is 100% on top of support material, then you're never going to get as good of a surface as if you printed directly on the bed. You can try to improve it some by using dense supports or even a dissolvable support material, but it will never be as good as direct on-the-bed printing.

Very helpful!! 
As Carl has said, you're not going to get a perfect curved under surface, however adding some dense support layers....say 2... with 100% fill will probably give you the best you're going to get.
If you don't have it set already, also try changing the Outline Direction (Layer tab) to Inside-out...and use 3 or 4 perimeters. If this compromises the surface finish further up the model, you may need to use two profiles; one for the lower section printing perimeters Inside-out, and the second for the rest of the model printing perimeters outside -in.
