2014—2016年,连续3年在山东省蓬莱市进行套袋试验,研究了二次套袋对‘烟富3’苹果产量、品质及经济效益的影响。结果表明,‘烟富3’苹果采用二次套袋(处理3)效果最好,单果重、可溶性固形物含量分别较一次套袋(处理1)提高6.6%、18.5%,总酸含量降低17.2%,而光洁度指数仅降低1.4%,每667m2产量提高6.5%,每667 m2效益提高50.5%。
In 2014-2016, three years of bagging experiments were conducted in Penglai City, Shandong Province to study the effects of secondary bagging on the yield, quality and economic benefits of ’Fu 3’ apple. The results showed that ’Yanfu 3’ apples had the best effect when using second bagging (treatment 3). The single fruit weight and soluble solid content were increased by 6.6% and 18.5% respectively and the total acid content decreased by 17.2 % While the finish index decreased by only 1.4%, the yield per 667m2 increased by 6.5%, and the benefit per 667 m2 increased by 50.5%.
