it was on cherry tree farm –we saw many animals.

it was on cherry tree farm –we saw many animals.
这个定语从句的关系词，应该用什么？
应该是：
it was on cherry tree farm that we saw many animals.
意思是：正是在这个樱桃（树）（水果？）农场里我们看见了很多动物。
首先，这是一个标准的it be。。。that。。。的强调句型，
其次这不是定语从句，而是主语从句，还原为正常语序是：
we saw many animals on （the？） cherry tree farm。
