you can use the --worker-exec option.

This is used to run php-fastcgi (or other software requiring specific
environment) under the uWSGI environment

uwsgi --limit-as 256 --worker-exec /bin/ls

As others have already said to you, remember that limits set by a parent
are inherited by all of the children. So running apps via fork+exec or via
attach-daemon in uWSGI will set their limit automatically.
