Effect of Bagging and Surpporting Techniques on Fruit Quality of ‘Red Fuji' Apple in Transformed Orchard

以经过改造的郁闭园"长富2"苹果为试材,研究了果实套双层纸袋和复合袋,配合铺反光膜、摘叶、转果等措施对果实外在品质和内在品质的影响。结果表明:套袋及其配套技术增加了单果重、果实直径和可溶性固形物含量,全面着色果实比例显著提高,果形指数、可滴定酸含量、维生素C含量变化不大,果实硬度降低;总体上提高了果实品质,套双层纸袋和复合袋对果实品质影响差异不大。

Taking ‘Red Fuji＇ apple from reconstructed closing orchard as material, the effect of baging double-deck paper bag and compound bag combined with the technique of pave tapetum lucidum,pick leaf and turn fruit on fruit appearance and internal quality were studied. The results showed that bagging and surpporting techniques increased single fruit weight,fruit diameter, and content of soluble solid. The proportion of comprehensive colour fruit promoted notablely. Fruit shape index, content of titratable acid and vitamin C changed rarely. Fruit firmness reduced. On the whole, fruit quality promoted. The difference was little of fruit quality for baging double-deck paper bag and compound bag.
