Abstract
With the tomato cultivar 'Chaoqunfenguan' as test material,the effects of different greenhouse films,including the inner-added-type EVA,PE and PVC films,and the coated-type EVA and PVC films,on the light transmittance,transmission of ultraviolet ray,heat conservation of greenhouse and growth,fruit quality and yield of tomato were studied in this paper.The coated-type anti-fogging EVA film had the highest UV transmission and light transmittance,and the best heat preservation;it also played obvious roles in promoting the tomato growth and increasing the fruit quality and yield.
