散射光薄膜对番茄生长和果实品质的影响

Effect of Diffuse Light Thin Film on Tomato Growth and Fruit Quality

以番茄品种博粉为试材,以普通薄膜为对照,研究散射光薄膜对番茄生长与果实品质的影响。结果表明：相对于普通薄膜,在散射光薄膜温室中生长的番茄长势更强,叶绿素含量更高,番茄果实数量和平均单果质量分别增加12.52%和7.71%,产量提高21.19%;果实的体积显著增大,果形更接近于该品种特征果形（果形指数为0.8~0.9）;在果实品质方面,番茄的可溶性固形物含量及VC含量都有显著提高。表明散射光薄膜不仅有助于番茄植株的生长,对果实的品质也有一定的改善。

Taking tomato variety ‘bofen＇ as experimental material and ordinary film as the contrast,this paper studied the effect of diffuse light thin film on tomato growth and fruit quality. The results showed that tomato had strong growth vigor under diffuse light thin film,the content of chlorophyll was higher,the fruit setting number and average single fruit weight were increased by 12.52% and 7.71%,respectively. Its yield was also promoted by 21.19%. Besides,the fruit volume was significantly enlarged. The fruit shape index was 0.8-0.9. Further more,its fruit quality was improved. The contents of soluble solid content and VC were remarkably increased,indicating the diffuse light thin film was not only helpful for promoting tomato plant growth,but also for improving its fruit quality.
