The invention concerns a material used in agriculture for increasing the amount of solar radiation received by plants of for modifying its quality, said covering consisting of a planar structure, with greater length than width, comprising reflecting blades (1), juxtaposed in the longitudinal direction of the width and maintained together by a yarn system (2). The system (2) consists of knitted fabric, produced on a knitting machine with overlapping stitches, with frontal weft insertion, according to a net-type weave from three warp thread laps (10, 11, 12) separately distributed to the needles via three bars with guides operating such that: the front bar (BI) operates according to a pillar stitch weave; the central bar (BII) operates according to a weave producing transverse links (4); the rear bar (BIII) distributes its yarns (12) to each needle according to a weave picked under the needle; the yarns (10, 11, 12) used for producing said knitted fabric are synthetic monofilaments; the reflecting blades (1) are picked over the whole length of the knitted fabric. |
