采用白色纸袋、黄色纸袋、花色纸袋和白色塑料薄膜纸袋4种纸袋,以不套袋为对照,研究不同颜色和质地的纸袋对温室‘火焰无核’葡萄产量和品质的影响,筛选出适宜设施‘火焰无核’葡萄套袋的纸袋。测定其果实单粒重、单穗重、可溶性固形物含量、总糖量、可滴定酸含量和糖/酸比,调查其颜色、采收期和病虫害的发生情况。结果表明:白色纸袋和白色塑料薄膜纸袋均有利于提高设施‘火焰无核’葡萄的平均单粒重和平均单穗重。在葡萄果实品质方面,白色纸袋和白色塑料薄膜纸袋有利于果实可溶性固形物含量、果实总糖量和糖/酸的增加;白色塑料薄膜纸袋对果实滴定酸含量无影响;白色纸袋和白色塑料薄膜纸袋有利于果实着色,颜色均一,同时可以提前采收期。白色纸袋处理的‘火焰无核’葡萄没有病虫害发生,而白色塑料薄膜纸袋病虫害发生最为严重。经综合分析,白色纸袋最有利于提高设施‘火焰无核’葡萄的产量和改善其品质,是适宜吐鲁番地区‘设施火焰’无核葡萄套袋的纸袋。
Using four kinds of paper bags: white paper bag, yellow paper bag, flower paper bag and white plastic paper bag, the effect of different color and texture of paper bag on the yield and quality of ’Flame Seedless’ ’Flame Seedless’ bag with paper bag. The single kernel weight, single spike weight, soluble solid content, total sugar content, titratable acid content and sugar / acid ratio were measured to investigate the color, harvest time and occurrence of pests and diseases. The results showed that both the white paper bag and the white plastic paper bag were beneficial to increase the average single ear weight and average single ear weight of ’Flame Seedless’ grape. In the grape fruit quality, the white paper bag and white plastic film bag are conducive to fruit soluble solids content, total sugar content and sugar / acid increase; white plastic film bag has no effect on the titration of fruit acid content; white paper bag and white plastic film Paper bag is conducive to fruit coloring, color uniformity, and can be harvested in advance. The “flame-free” grapes treated with the white paper bag did not cause pests and diseases, while the white plastic film bag was the most serious. After a comprehensive analysis, white paper bag is most conducive to improving the production of ’Flame Seedless’ grape and improving its quality. It is suitable for Tuofei Flame’ non-nuclear grape bagging bag.
