The results showed that light adjusting film had better effect (0.3-2.0 ℃) than ordinary film in increasing ground temperature, and light adjusting film increased the number of tobacco effective leaves, shortened field growth period, promoted tobacco mature, increased yield and higher grade leaves, and output. Therefore, light adjusting film has high potential in flue-cured tobacco production. keywords: light adjusting film; soil temperature; flue-cured tobacco; yield
