Vale, second in the table, have slipped five points behind League Two leaders Gillingham after losing five of their last eight matches.
Three of those defeats make up a four-game winless run at Vale Park, where Adams' side have not tasted victory since beating AFC Wimbledon 3-0 on February 5.
Bottom-of-the-table Aldershot visit Burslem on Saturday for a game which the Vale boss believes is up there with the club's biggest of the season.
"People expect you to win your home games, but it's never that easy," Adams said.
"With recent results at home, perhaps some people are not as confident as they should
be. But after last weekend's result (a 2-0 away win at York) we're feeling a lot better about ourselves now and I'm hoping it will kick-start us again, especially at Vale Park.
"Home form is always important and the Aldershot game is massive now, probably one of the biggest of our whole season. It's a cup final for us and we have to approach it in that manner - as we do all of the remaining seven games.
"Getting to that 70-point mark will be a big psychological boost for us. The quicker we can get there, the better. If we can do it on Saturday, that would be great."
