Title
(EN) AGRO-HORTICULTURAL SOIL COVER FILM
(FR) COUCHE DE COUVERTURE DE SOL AGRO-HORTICOLE
(JA) 農園芸用覆土フィルム
Abstract
(EN)
An agro-horticultural soil cover film that reflects visible radiation and absorbs infrared radiation, reflecting light needed for growth of plants toward the plant side and absorbing heat-generating infrared radiation to thereby warm soil, and that does not raise the air temperature within a greenhouse. There is provided an agro-horticultural soil cover film having a white light reflection layer containing a white light reflection material and an infrared absorption layer containing infrared absorption material microparticles, characterized in that the infrared absorption material microparticles are composed of tungsten oxide microparticles and/or composite tungsten oxide microparticles, the tungsten oxide microparticles being those of the general formula WOX (2.45≤X≤2.999), the composite tungsten oxide microparticles being those of the general formula MYWOZ (0.001≤Y≤1.0 and 2.2≤Z≤3.0) having a hexagonal crystal structure.

La présente invention concerne une couche de couverture de sol agro-horticole qui réfléchit les radiations visibles et absorbe les radiations infrarouges, réfléchissant la lumière nécessaire à la croissance de la plante vers le côté de la plante et absorbant les radiations infrarouges générant de la chaleur vers le sol ainsi chauffé, et n'augmentant pas la température de l'air dans une serre. Elle met à disposition une couche de couverture de sol agro-horticole comportant une couche de réflexion de la lumière blanche contenant un matériau réfléchissant la lumière blanche et une couche d’absorption infrarouge contenant des microparticules de matériau absorbant les infrarouges, caractérisée en ce que les microparticules de matériau absorbant les infrarouges sont composées de microparticules d’oxyde de tungstène et/ou de microparticules d’oxyde de tungstène composite, les microparticules d’oxyde de tungstène étant de formule générale WOX (2,45 ≤ X ≤ 2,999), les microparticules d’oxyde de tungstène composite étant de formule générale MYWOZ (0,001 ≤ Y ≤ 1,0 and 2,2 ≤ Z ≤ 3,0) et présentant une structure cristalline hexagonale.
