Abstract: The light conditioning biology film for agriculture can transfer certain unused solar radiation in photosynthesis of vegetables into photosynthetically active radiation through the fluorescence additive in it, its value not only lies in promoting the growth of vegetables and increasing yield but also in affecting the nutrients in vegetables. By quantity mensuration of dissolubility sugar, Vitamin C, titrable acidity, coarse protein in tomatoes, cucumber, pimiento grown under the sunlight conditioning film and the conventional film according to GB/T method series and the following analysis, we get the increase ratio of these nutrients in vegetables under light conditioning film comparing with the conventional film.
