摘要:选用8种不同类型果袋对‘岱妃’桃进行套袋处理,研究了套袋对果实大小、内在品质和果皮色差的影响。结果表明,套单层黑色无纺布袋的果实单果重最大,套双层外黄内黑纸袋的果实内在品质较好,套双层外黄中黑里红纸袋的果实色差最好。综合各项指标,双层外黄内黑纸袋是8种果袋中最适合‘岱妃’桃套袋的袋型。

The results showed that the fruits bagged with single-layer black non-woven bags had the highest single fresh fruit weight; the fruits bagged with double-layer black-inner and yellow-outer bags had the best internal quality; the fruits bagged with double-layer red-inner,black-middle and yellow-outer bags had the best fruit chromatism. It was concluded that the double-layer black-inner and yellow-outer bags was the best for Daifei peach. Key wordsPeach; Bagging; Fruit quality; Chromatism
套袋技术在果实生产中应用广泛,是提高果实外观、生产优势果品的有效生产技术。套袋可以有效地减少病害的侵染和鸟虫的啄咬,减少农药的使用,并且可以提高果实表面的光洁度。目前市场上销售的果袋型号较多,用户根据自己的喜好使用,缺乏专业指导。为了探明不同果袋对桃果实外在品质和内在品质的影响,为合理使用果袋提供理论支持,进一步提高桃果实品质,特进行本试验。
