摘要
以番茄品种"太宝1号"为试材,以传统内添加型EVA和PVC棚膜为对照,研究涂覆型EVA无滴消雾棚膜的透光性、保温性、紫外线透过率及对番茄生长、品质、产量的影响。结果表明:与内添加型EVA和PVC棚膜相比,涂覆型EVA棚膜的透光性、保温性及紫外线透过率均有所提高,明显促进番茄生长,显著提高了果实糖酸比、可溶性糖、番茄红素及VC含量,同时提高了番茄产量,比使用内添加型EVA和PVC棚膜分别增产12.2%和34.8%。
The light transmittance, heat retaining property and UV transmittance of the coating EVA anti -fog greenhouse film and its effects on the growth, quality and yield of tomato were studied with the tomato variety ＂Tai Po 1＂ as the material and the inner - added EVA and PVC types of anti - fog greenhouse film as the controls. As the results, using the coating EVA anti -fog greenhouse film, the light transmittance, heat retaining property and UV transmittance were increased; the growth of tomato, the sugar - acid ratio and the contents of soluble sugar, lycopene and Vitamin C in fruit were significantly improved;the yield of tomato was increased by 12.2% and 34.8% respectively compared with the inner - added EVA and PVC types of anti - fog greenhouse film.
