摘要

The panel (S) has a parallelepiped shaped structure (1) with air sending and aspiration chambers provided with vertical air sending openings and air aspiration openings. The openings are transversely aligned face-to-face so as to be served as common air aspiration and sending units (2), so that the panel is utilized in series with identical panels that are alternatively turned for 180 degrees around a vertical axis so as to simultaneously process narrow rows of plants to allow the openings to face air sending and aspiration openings of adjacent panels, according to different orientation.
