Title: Packaged tunnel-type greenhouse for row crop

Abstract: A tunnel-type greenhouse is packed in a mailing tube with wires constituting support-wicket halves received in a core tube on which a synthetic-resin foil usable as the greenhouse wall is wound. The wire wicket halves are joined together by short sleeves and formed into wickets that are driven into the ground in a row. The foil is unwound from the core tube which is broken in two at a central weakened region to form two stakes that are driven into the ground at the ends of the row. String unwound from the ends of the core tube is secured between these stakes and the apices of the end wickets. The foil is stretched between the stakes over the wickets and extra wickets may be engaged over the foil to hold it in place.
