Abstract:
Light conversion film is a kind of functional agricultural film which can convert light quality and absorbed sunlight into light needed by plant photosynthesis.In this study，Italian lettuce was used as the experimental variety to study the effect of light conversion film on greenhouse environment，soil environment and lettuce growth and development,in order to provide a theoretical basis for the development of light conversion film in agriculture.The results showed that the environmental parameters of the greenhouse were effectively improved by the light conversion film.During the whole growth period，the average air temperature，average light intensity，average CO2 concentration and soil temperature of the greenhouse were 2.10%，3.79%，31.73% and 3.32% higher than those of the common greenhouse.For crop growth，the plant height，leaf length and SPAD of lettuce in the light conversion film greenhouse increased by 3.55%，2.55% and 2.42% respectively，and the average yield of lettuce per hectare increased by 8.54%.As a whole，the air，light and soil environmental parameters of greenhouse were improved under the use of light conversion film，which further promoted the growth and yield formation of lettuce.
