There is a specific rule in magic that prevents lands from being played on your opponents turn.
115.2a. Playing a land is a special action. To play a land, a player puts that land onto the battlefield from the zone it was in (usually that player's hand). By default, a player can take this action only once during each of his or her turns. A player can take this action any time he or she has priority and the stack is empty during a main phase of his or her turn.
305.3. A player can't play a land, for any reason, if it isn't his or her turn. Ignore any part of an effect that instructs a player to do so.
