Organic pigment will degrade due to oxygen when heat ray shielding sheets of curtains in a greenhouse contain the organic pigment. The invention provides a green house with a heat ray shielding sheet restraining degradation of organic pigment. Plants are planted in the greenhouse provided with a heat ray shielding sheet. The heat ray shielding sheet is provided with a first transparent layer, a second transparent layer and a third transparent layer. The first transparent layer is provided with oxygen permeation coefficient lower than 100 cc/m<2>*24hr*atm. The second transparent layer contains organic pigment with heat ray shielding ability. The third transparent layer is provided with oxygen permeation coefficient lower than 100 cc/m<2>*24hr*atm. The second transparent layer is clamped between the first transparent layer and the third transparent layer. |
