So! I answer to myself... This can be usefull for people who have
several systems installed and who use xfce (I don't know if the same
problem occurs for kde or gnome): icons of partitions of other system
show on the desktop.

Create a file (98-local.rules for instance) in /etc/udev/rules.d with:

ENV{ID_FS_UUID}=="17e0b155-4d77-4769-b568-723329c5f656", \
ENV{UDISKS_IGNORE}="1"

for each partition you want to hide.

You can find the right syntax, ENV{ID_FS_UUID} for instance, with the
command:

udevadm info /dev/md2

After reboot, icons do not show on the desktop.
