Rickie Lambert grabbed his eighth of the season from the penalty spot and Guly do Prado, Adam Lallana and substitute Richard Chaplow all got in on the act, while David Connolly was unlucky to have one ruled out for offside at the end.
"We scored four very good goals," said Adkins.
"David Connolly scored another right at the end which wasn't offside but the linesman gave it unfortunately.
"They were all good goals that we scored. Frazer Richardson storming down the right-hand side and linking up well with Guly, another great cross for Adam Lallana, and then the final goal from Richard Chaplow was a great goal at a great time."
