short answer: you don't. qsynth has no plugin form whatsoever.

though, there are the current alternatives:
a. fluidsynth-dssi: works on qtractor; no dice on ardour.
b. calf-fluidsynth (lv2): works on both, qtractor and ardour.
c. a-fluidsynth (lv2): same as above, but no gui here (stock/generic
host ui applies).

looking into the later, as Hanspeter already stated, you can load it and
work with it onto every lv2 host you can think about, provided you set
LV2_PATH environment variable appropriately

eg. export LV2_PATH="/usr/local/lib/ardour5/LV2:$LV2_PATH"
(nb. in my case, ardour5 is installed below /usr/local; ymmv).

once set permanently (maybe on .profile or .bashrc) you may find Ardour
Team's plugins from any other lv2 host, like say, qtractor (which i
think is what you're after;)

ps. i've tested and it works, although i kind of fail to make the
a-fluidsynth reverb settings to work somehow. chorus yes. reverb nope.
maybe's my bad, maybe already fixed upstream. anyway, as far as i can
tell, it really doesn't give you access to most of the internal sf2
controls. but again, for that matter, neither do calf, qsynth or
fluidsynth-dssi.

hth.
cheers
