Abstract

In order to understand the radiation transmittance performance of agricultural plastic films, the plastic films were scanned using VARIAN Cary-50 Ultraviolet/visible photometer and FT-IR 8700 Far infrared spectrometer (Shimadzu) in this paper. At the same time, the UV, PAR and Infrared(IR) ray radiation transmittance spectrums were analyzed. The results showed: ①the transmittance in UV part, PVC was the lowest, EVA was next, and PE was much higher. ②in PAR part, the transmittance area ratio was calculated based on the scanning results in this paper. PVC was abundant in the blue area, PE was the richest in yellow and green areas; the red and far red areas were shown in R/FR, the R/FR value was consistent in new films, but after 100 days, the R/FR value of PVC dropped by 0.076. The R/FR values of PE and EVA both dropped by 0.050. ③in IR area, PVC had the outstanding infrared impediment ability, PE was next, and EVA had a bad impediment ability.
