利用挤压法使荧光染料渗入聚乙烯膜中，制造出一种新的温室塑料膜。荧光染料将光谱的绿色部分转换成红色。用这种荧光塑料膜作为温室膜与不染色的透明膜比较，能使西红柿的产量增加１９．６％、玫瑰花的花枝数量增加２６．７％。作物产量的增加，主要是由于作物对太阳光谱变化的生态反应引起的，它能增强植物有机组织的发育，也能增加光合作用。
The use of extrusion method to fluorescent dye into the polyethylene film, to create a new greenhouse plastic film. Fluorescent dyes convert the green part of the spectrum to red. Using this fluorescent plastic film as a greenhouse film compared with a non-dyed transparent film increased the yield of tomatoes by 19.6% and the number of flowering branches of roses by 26.7%. The increase in crop yield is mainly due to the ecological response of the crop to changes in the solar spectrum, which enhances the development of plant organic tissue and also increases photosynthesis.
