Trott said it was a brave decision to bat first but admitted they were well short on a "350-360 wicket".
Trott said his players would have benefited from having the match at the same venue where they play defending champions England on Sunday.
Afghanistan are playing at their third World Cup and have now lost 16 of their 17 matches, their only victory coming against Scotland in 2015.
"Azmat played really well, stepping up to number five and showing the talent and the pedigree that he's got as an all-rounder," Trott said.
"So those are the things we're looking to get right going forward and get ready for England."
