[The reformation of tomato ecology using photo-ecology film]

The action spectrum of photosynthesis of tomato was studied with excitation and fluorescence spectra of its leaf. To simulate action spectrum of tomato the fluorescent auxiliary was specially prepared and used to make the photo-ecology film. The film was used to cover the roof of greenhouses for planting tomatoes in Jianguo village of Xinfa town, Daoli district, Harbin. The survey of ecology conditions, tomato growth and yield has been made in comparison with those in the greenhouse using normal film. It is shown that the yield of tomato in the photo-ecology film greenhouse has increased by 53.7%, which leads to a production value rise of 61.4%.
