Recent research has demonstrated that multifunctional light-converting greenhouse films can significantly improve both crop yield and fruit quality by optimizing the light-temperature microenvironment. Compared with conventional greenhouse films, novel light-converting films optimize spectral composition and increase light intensity by over 5.04% while maintaining stable light transmittance under low incidence angles. The study found that these films significantly enhance accumulated temperature and improve stress tolerance under low-temperature and low-light conditions. Following application of the novel greenhouse film, tomato yield increased by 4.39%, with simultaneous improvements in nutrient indicators including sugar-to-acid ratio, vitamin C, and soluble protein content. The research confirmed for the first time that accumulated soil temperature is the core driving factor of tomato plant morphology and root development, establishing an integrated regulation pathway from optimal light and temperatures to improved fruit quality and yield. These findings provide scientific support for the optimization and commercialization of light-converting films designed for greenhouse cultivation.
