The 27-year-old scored six goals during the month in the form of two hat-tricks, in a 7-1 demolition of Bolton and a 5-1 thrashing of Blackpool.
He helped Reading to three wins and a draw from their five league matches and now has 13 goals for the season.
Royals director of football Nicky Hammond told Press Association Sport: "Alfie has been smashing.
"We know what a good player he is, he's an out-and-out goalscorer and he's been a big part of our recent run of form.
"Every day Alfie comes in and works hard, practices his finishing, and he's a great example to the younger players.
"His goalscoring record at every level is up there with the best."
