Light conversion film（LCF）is a functional agricultural films，which could absorb
part of the ultraviolet light from sunlight and convert it into red-blue light to be utilized by plant
photosynthesis．Taking the strawberry variety ‘Hongyan’as test material，this paper studied the effect
of LCF on strawberry growth and quality．The results showed that compared with the ordinary film
（POF），LCF could increase average daily indoor temperature by 0.39 ℃ and accumulated temperature
during growth period in green house by 75.0 ℃．During full productive stage，the photosynthesis
rate and chlorophyll content of strawberry leaves treated with LCF were increased by 14.3% and
14.0%，respectively．Beside，LCF treatment could remarkably promote strawberry early maturity
and yield increase．Compared with POF treatment，LCF-treated strawberries could mature 10 days
earlier，and increase yield by 3.3 t · hm^-2 ．Besides，LCF could obviously improve the fruit quality．
The VC content of LCF-treated strawberry in the first and second harvest periods were increased 16.1% and
24.4%，respectively than that of those treated with ordinary film．While，the differences in soluble sugar
content were not significant．
