以红色彩椒品种‘凯特琳’为试验材料,研究了加入转光剂和红色母粒涂覆型消雾无滴EVA棚膜的透光性、保温性及对红色彩椒植株生长、果实品质和产量的影响。结果表明,与消雾无滴EVA棚膜相比,专用膜的保温性有所提高,明显促进红色彩椒植株生长,有利于提高彩椒产量。且专用膜覆盖下红色彩椒果实转色早且均匀,果实VC含量、糖酸比、花青素含量明显提高。总体来看,甜椒专用膜更有利于提高红色彩椒果实的综合品质。
With the red cauliflower cultivar ’Caitlin’ as the experimental material, the translucency and heat preserving properties of the spray-coated and red masterbatch-coated EVA film without spray were studied, and the effects on the plant growth, fruit quality And the impact of production. The results showed that, compared with the fog-drip-free EVA film, the thermal insulation of the special film was improved, which obviously promoted the growth of the red-color pepper plant and promoted the production of the sweet pepper. And the special film covered the red color pepper fruit turn early and even color, fruit VC content, sugar acid ratio, anthocyanin content increased significantly. Overall, the special pepper film is more conducive to improving the overall quality of the red bell pepper fruit.
