Abstract: Four-year-old kansu peach ‘Taiwan farmers sweet’ (Prunus persica cv.tainongtianmi) which was grown in solar greenhouse was used as experiment material to research the comprehensive influence of Coating- anti-fog film and inner-added anti-fog film on light and temperature condition and fruit quality. Results showed as follows：Coating- anti-fog film has better ultraviolet-B transmittance, insulation and moisture retention than inner-added anti-fog film through the results. Meanwhile Coating-anti-fog film is more conducive to promoting the growth of the fruit, sugar, starch, also reducing the synthesis of organic acids and improving sugar acid ratio, but goes against the synthesis of protein. In a word Coating- anti-fog film is more conducive to improveing the comprehensive quality of the fruit.
