Or, more generally, what is the best way to use an artificial ground
with an antenna like that one, when a proper metallic ground is not
available?

An artificial ground tunes the ground wire such that it appears as a very
low impedance point at the rig. That ground wire should be tied to the rig
chassis. Another way to solve the problem is to put resonant radials on the
base of the vertical. In fact, your DK3 configuration will be a dog
without radials.
