| Outline of Final Research Achievements |
Horticultural crops are cultivated in greenhouses almost year-round, including during periods of high temperature. However, high temperatures in a greenhouse can have negative effects on plants. Therefore, measures to counter heat are becoming an urgent issue. However, the common method of using shading material decreases the amount of light available for photosynthesis. In this study, we examined the influence of a film that limits near-infrared light transmission without reducing the transmission of visible light to the cultivation environment and crops. This heat-barrier film was used during periods of high temperature. While the temperature in the greenhouse was not affected, the soil and plant temperatures decreased, and the yields of crops such as eggplant and paprika increased.
The film was a valuable countermeasure to heat, but it is necessary to be careful when using the film year-round, because it might decrease the crop yield during very cold periods.
