摘要
稀土转光薄膜是一种具有能改变透过薄膜的阳光光质功能的新型农用薄膜。农田应用试验结果表明，与普通聚乙烯薄膜相比，稀土转光膜可以提高光温效应，透光率可提高9％左右，棚温增加1℃左右，并能增强植物光合作用能力，生物效应明显，可使作物产量增加，品质改善，其中番茄、黄瓜、草莓增产14％，茄子增产5．67％，产品中Vc及糖的含量有所提高。
The rare earth film is a new agricultural film which could transform light quality. The results of field experiments indicated that when it was used to made a shed,its light temperature effect was higher than that of common agricultural film. The light transmission rate and the inside temperature increased about by 9% and 1℃, respectively. This made crops photosythesize and grow vigorously and so obvious improvement was made in yield and quality of crops. The yield increased by 14% for tomato,cucumber and strawberry,by 5. 67% for eggplant. There were more or less increases of Vc and sugar content in plants.
