Pass the id of one node by url for new node
One easy way to do this is with the module

nodereference_url


  The Node Reference URL Widget module adds a new widget to the Node
  Reference field type. It auto-populates a node reference field with a
  value from the URL, and does not allow this value to be changed once
  set. It can automatically provide a link on the referencing node
  types, that will contain the proper URL to prepopulate the field.
