LIGHT-REFLECTIVE SHEET FOR FIELD CROP CULTIVATION AND CULTIVATION OF FIELD CROP USING THE SAME SHEET

摘要

PURPOSE:To accomplish the title cultivation by setting up a light-reflective sheet under field crops to be cultivated in a dangling state and irradiating the lower face of the crops with the resultant reflected light to promote their growth. CONSTITUTION:Grapes 1 are cultivated in a dangling state from a shelf 3. A sheet 6 is horizontally set up under the grapes 1. This sheet 6 is a band- shaped light-reflective sheet, consisting of a white film made from synthetic resin, aluminum foil film or silver film. Therefore, incident rays from above are reflected on the upper surface of the sheet 6 and hit the lower face of the grapes 1 to effect promotion of their growth.
