As long as I know it is not possible to use the sections name.
I would avoid to have the same field name even between differents sections.
Or a option is to pass the field ID and then create classes or constants to not hard code IDs
@Html.Sitecore().Field("{E77E229A-2A34-4F03-9A3E-A8636076CBDB}");
or
@Html.Sitecore().Field(MyTemplate.MyGroup.Foo); //where foo returns the id.
EDIT:
MyTemplate.MyGroup.Foo
would be classes/structs you created your own just to make easier and more reliable the references all over you project. (you can use a tool to auto-generate it like a T4 template)
public static struct MyTemplate
{
public static struct MyGroup1
{
public static readonly ID Foo = new ID("{1111111-1111-1231-1231-12312323132}");
}
public static struct MyGroup2
{
public static readonly ID Foo = new ID("{9999999-9999-xxxx-1231-12312323132}");
}
}
