以富士苹果为试材，在宁夏引黄灌区中卫和青铜峡两个苹果主产区研究了套袋对苹果品质及农药残留的影响。结果表明，套袋果光洁度、着色指数、商品果率、含水率均高于不套袋果，而硬度、可溶性固形物、固酸比、花青苷含量则明显低于不套袋果。套袋对果形指数和单果重影响不明显，但有降低果实单果重的趋势；套袋可有效降低果实农药残留，但对提高果实食用安全性的优势并不突出。综合分析，套袋的影响弊大于利，“无袋”栽培将是未来宁夏苹果产业的发展方向。

Taking Fuji apple as material，the differences of fruit quality and residues of pesticides is studied by the method of bagged and non-bagged fruits in Zhongwei and Qingtongxia of Yellow River Irrigation Area， which are two different main apple production area of Ningxia. The result shows that the smooth index，color index，commodity rate and rate of water content of bagging fruits are higher than non-bagging fruits，but the firmness，soluble solids，solid acid ratio and anthocyanin content are all significantly lower than those of non-bagging fruits .Bagging had no effect on fruit weight and fruit shape index，might reduce fruit weight .Bagging can effectively reduce the fruit pesticide residues，but the advantages of bagging to improve the edible safety of fruits is not prominent .
